Why the manual step?

18th January 2010

One of the consequences of buying a new camera is that your current photo processing software may not be fully equipped for the job of handling the images that it creates. This is a particular issue with raw image files and Adobe Photoshop Elements 5 was unable to completely handle DNG files made with my Pentax K10D until I upgraded to version 7. Yes, I do realise that the upgrading camera should been in order but I only lost the white balance adjustments so I could with things as they until upgrading gained a more compelling case.

As things stood, Elements 7 was unable to import CR2 files from my Canon PowerShot G11 into the Organiser so it was off to the appropriate page on the Adobe website for a Camera Raw updater. I picked up the latest release of Camera Raw (5.6 at the time of writing) even though it was found in the Elements 8 category (don’t be put by this because release notes address the version compatibility question more extensively). Strangely, the updater doesn’t complete everything because you still need to copy Camera Raw.8bi from the zip archive and backup the original. Quite why this couldn’t have been more automated, even with user prompts for file names and locations, is beyond me but that is how it is. However, once all was in place, CR2 files were handled by Elements without missing a beat.

A new acquisition

16th January 2010

Back in the early days of this blog, I mulled over the idea of having a high-end digital compact camera to complement a DSLR that then was delivering very dusty images; that Canon EOS 10D was cleaned since then and comes in for occasional use to this day. That was nearly three years ago and a first generation Ricoh GR Digital was the item that then was catching my eye. At the time, I failed to justify spending that much money on such a thing and ended up acquiring a new Pentax K10D DSLR instead. The question that rattled about my head was this: what was the point of spending DSLR money on a compact camera? Its one that never really went away and comes to mind when you see the prices of interchangeable lens compacts like Olympus’ Pen and equivalent offerings from Panasonic and Ricoh (there, it’s interchangeable lens units rather than actual lenses).

The strongest counterpoint to the cost conundrum is the little matter of size. SLR (film or digital) cameras are sizeable things and there is a place for having something that drops into a pocket. It is that which has propelled me into taking delivery of a Canon PowerShot G11. It may need a good-sized pocket but, unless you are going out with no jacket, it shouldn’t be a problem most of the time. For those shorter sorties when I don’t fancy bringing an SLR out, it well-built and looks the business though some acclimatisation is in order to make the best of the knobs, buttons and menus. Nevertheless, the included manual will help with this process (there’s a paper quick start guide and more detailed documentation on CD).

Canon PowerShot G11

The camera hasn’t seen extensive use just yet so here are a few early impressions. Firstly, there’s the matter of size: it’s even smaller than the first camera that I ever bought (more than fifteen years ago) and that was a Ricoh 35 mm compact film camera. That comparison is even more striking when you consider the feature sets. The Ricoh was a fixed 35 mm lens affair with things like date and time stamping, ISO choice and a nod towards scenic mode selection. In contrast, the much newer Canon is loaded with the sorts of things that normally are found almost exclusively on SLR’s, starting with its effective 28-140 mm focal length range.

Exposure modes such as manual, aperture priority and shutter priority complement scene-based modes and another for movies (not a concern of mine, it has to be said). As if that weren’t enough, there’s exposure compensation too. It came as a surprise to me to find a form of manual focussing included though it is not as convenient as turning a focussing ring on a lens. You can see the inbuilt flash above but there’s also a hotshoe and a place to attach a tripod too. Settings like white balance and file format are accessed using the Function/Set button with the lever underneath the shutter release button controlling the focal length of the lens. In addition, there’s also image stabilisation and that’s important when you’re using live view to compose a photo. Spot metering and focal point selection are other things that find their way into the package. Some may be excited by other things but exposure and focussing are essential for any photographic efforts.

An optical viewfinder is included and it has dioptre settings too but my first impressions are that live view though the rear screen trumps it and I see no need for such things on SLR’s. That also flips out from the camera body and can be rotated either for self-portraiture or for folding back in on the camera body for use like a non-articulated screen. Another use is with those occasions when the subject means holding the camera in positions that would be impossible with a conventional screen; holding the camera over your head or down low on the ground are the sorts of situations that come to mind.

Of course, there’s more there than those features that I have listed and the specifications on the Canon website are as good a place to start as any. So far, my only testing has been of the cursory checks variety and to make sure that the thing works properly. Still, this has given me more of a feel for the camera and how it operates. As you’d expect, high ISO settings are noisy but a bigger surprise was that the smallest aperture setting is f/8. Being used to SLR’s, I was expecting to get f/16 and its like on there but a spot of internet investigation showed that I should have been taking the size of the sensor into account with my expectations. Any trials so far have been in dull weather so I’d need to use it in a wider variety of conditions before giving it the sort of wider appraisal that you’d find in the likes Outdoor Photography (who liked it, it has to be said). For what it’s worth, I have found no major criticism so far though I cannot see it usurping my SLR’s but that never was the intention anyway.

Temptations, temptations…

19th August 2009

Pentax K-7

The last time that I went out and bought a new camera was over two years ago and I am minded not to make another purchase for a while. Apart from damage to the battery cover arising from a fall, my Pentax K10D has survived so far without a problem and I admit to being satisfied with the photos that it makes. Following a professional sensor clean, my Canon EOS 10D has been pressed into service over the past few months too. In the meantime, 6 and 10 megapixel sensors generate nowhere near the attention that might have been case a few years back but that’s by the by. In fact, the megapixel race seems to have stalled with features like video being added to stills cameras over the last year and live screens coming to prominence also. Neither would make me rush out to buy a new DSLR anyway, perhaps because having things the old way suits me just fine and megapixel counts never ever moved me in the first place either.

That’s never to say that the likes of Pentax’s K-7 or Canon’s EOS 50D and 5D Mark II don’t capture my attention with their promises of better quality. However, with things the way that they are in the world, I am more likely to hold onto my cash or maybe invest in new photo processing software for making the most of what I already have. Ideas for photography projects creep into my head when I get to looking over my online photo gallery and realise that not have my tastes changed but my photographic eye has developed too. That seeing of things in a new light may mean that old subjects get revisited and I don’t need a new camera to do that.

Olympus E-P1

High end compact cameras such as Canon’s G11 and Ricoh’s GR Digital III do detain attention for a while but a quick look at their prices proves that you really got to need the portability and I never can justify the outlay when a DSLR will do all that I want from it, and perhaps even for less money. While I admit to pondering the purchase of a GR Digital to cover for the EOS 10D while it was away for cleaning, the Pentax came to be acquired when I realised that the versatility of a DSLR was too much to lose, even for a while. Olympus’ E-P1 may have bridged the gap but the old question of going miniature for the price of a full sized article recurs.

All in all, I am going to stick with what I have right now. We are coming to a time of year when things appear more golden and that combination of lighting and colour are what really matters, not how many megapixels is in you camera sensor unless you are making large prints or supplying stock libraries. As long as my cameras continue to deliver pleasing results, I’ll stick with improving my skills and taking my time over that task, even with all the announcements of new cameras at various exhibitions and shows.

No autofocus?

25th March 2009

Sigma 18-125mm f/3.8-5.6 DC HSM zoom lens

Recently, I recently treated myself to a Sigma 18-125 mm f/3.8-5.6 DC HSM zoom lens for my Pentax K10D. There was a wait for the item to appear and I then found that the lens’ autofocus facility wasn’t compatible with the body. Standard wisdom would have it that I sent the thing back and ask for a replacement or a refund.

Perhaps inexplicably, I did neither. In fact, I came to the conclusion, that since I make photos of landscapes anyway, that been slowed down by the lack of autofocus was no bad thing except perhaps when appealing light makes fleeting appearances. It is true to say that a used Pentax manual focus lens would have been cheaper but I did what I did.

The camera’s autofocus indicator still works and the 18-55 mm zoom that came with the camera wasn’t impressive anyway, so taking matters into my own hands was something that happened a lot. Now, I have better quality glass in front of the sensor and with a metal mount and longer range too. The lens comes with a petal hood too, though I keep that for when I really need it rather than keeping it on the lens and stopping myself focussing the thing.

Speaking of zooming and focussing, the controls work well and smoothly without being at all loose. The AF setting gets used to lock the focus and the zoom can be locked at the wide end so that the lens doesn’t get into the habit of zooming under the influence of gravity, not a bad thing. For future lens purchases, I might be more inclined to ask about compatibility next time around (I may have been spoiled by the Canons that I used to use) but I remain content for now.

All in all, it feels like a quality item and it’s a pity that Pentax saw fit to make the changes that they made, or that Sigma didn’t seem to have kept up with them. Saying that, my photographic subjects usually don’t run off so being slowed down is no bad thing at all, especially if it makes me create better photos.

Another avalanche of new DSLR’s…

24th January 2008

Pentax K20D

A flurry of new DSLR announcements came out today; they seem to come in droves when they do arrive but I reckon that upcoming photography shows might have something to do with it. Canon replaced its entry level offering with the 12.2 megapixel EOS 450D. Yes, I know that megapixels aren’t everything but a goodly number does make a rather good impression and Canon’s range looks a bit lop-sided again with the entry level DSLR on the surface of it having the potential for recording more detail than the next one up in their range, the EOS 40D. It almost seems that it would have been more sensible to delay the arrival of that camera until after the 450D and give enthusiasts a really impressive option. As it stands, they might end up playing into the hands of Nikon with its D300, a strong contender if I were on the market looking for a DSLR. Pentax displays no such idiosyncrasies with it 10.2 megapixel K200D and 14.6 megapixel K20D, and Samsung has also presented their variant of the latter: the GX200. It will be interesting to see reports of how all of these new arrivals perform. Launches like this do not take long to make your once shiny acquisitions look dated and that fate certainly seems to have befallen my K10D. For some reason, that reminds me that my trusty old EOS 10D needs to be sent away for cleaning, a job that has been on the to do list for while.

More digital than film?

26th October 2007

Despite the rampant progress of digital photography, I have continued to stick with film and sit astride the fence. That is something that I wish to continue but my most recent trips into the outdoors have seen me use my Pentax K10D exclusively. That, however, could be something to do with the subject matter. My most recent trot took me into what might be described as featureless moorland, a tricky subject to capture in the best way. So, possibly because of the lesser likelihood of success, I stuck with digital since any lack of success costs less. Previous trips took me out and about locally where I live and I seem to be more likely to use digital, possibly because I have been around the area a lot with my film camera anyway. Also, the vistas, as pleasant as they are, do not possess the drama of the likes of Highland Scotland, the English Lake District, or the mountainous parts North Wales.

That does lead to the impression that I am keeping film for the new and dramatic stuff and it may be true. it is, however, not entirely deliberate and I will continue to take both digital and film cameras with me on my excursions. My reason for taking a DSLR is that I want to put some photos into my posts on my outdoors blog and the world of digital easily speeds that process; my laggardness with getting films processed would add to the time taken too. And film? There is still a certain something about getting a print done for a photo album and the process does force me to print my photos, something that is not a compulsion in the digital world. There is also a greater feeling of permanance with film, a format that has been with us in its various guises for over a hundred years. With the pace of change in the world of computing, would the likes of DNG hold its own for that long?

A rake of new cameras

30th August 2007

Nikon D300The websites of Amateur Photographer and Tech.co.uk are good places to find out what is happening in the world of digital cameras, which is just as well given the recent camera launching frenzy. It all seemed to start off with Canon’s EOS D40 and EOS 1Ds Mark III. The former seemed to be a case of playing catch up but I still think that Canon should have used the opportunity to pull ahead, at least in the megapixel stakes; Sony is working on a 12 megapixel offering and could be about cause of 12 megapixel sensors becoming the norm for consumer digital SLR’s like they did with the 10 megapixel level. I realise that megapixels aren’t everything but it has seemed to go like that thus far. Playing catch up doesn’t apply to the 1Ds Mk III with its having a monster sensor resolution of 21 megapixels and, needless to say, the improvements to the favoured DSLR of landscape photographers don’t stop there. Nikon were also in the fray with new 12 MP offerings: D300 for the enthusiast and D3 for the professional. The sensor in the latter interestingly features a sensor that sits between full frame and the more usual APS-C sizes. Panasonic have also announced a new DSLR but a number of manufacturers have new digital compacts on the market too. All of the previous makers have something as does Olympus. It was amazing to see this all happening at once but I suppose that’s how it goes. IFA has been on over the last week but some launches preceded this; it’s usually something big like Photokina that results in this sort of thing…

Update: I have discovered since the Nikon’s D3 has a sensor sized in the full frame domain. It might be 36mmx23.9mm rather than 36mmx24mm but the FX format comes extremely close and the advent of full frame DSLR’s being purveyed by a number of manufacturers may be upon us.

Taking a camera on a walk…

24th July 2007

On Saturday, I happened to be in Jessops and overheard a salesman emphatically state that you don’t buy a camera for its specifications but for the photos that it produces. While his tone of voice was a touch condescending and he seemed to be putting down a DSLR, he was essentially right. Nevertheless, the specifications do help you get the images and they have to be seen in that light. For instance, having on-board sensor cleaning may save you from having either to clean the thing yourself or send the camera away for the professionals to do the needful, a much safer option in my view. And there may be occasions where image stabilisation is very useful, low light wildlife photography for instance. Yes, there are features that I consider surplus to requirements, like live viewing and movie capture and that is very much due to my buying cameras to make photos. The salesman in question would surely have agreed…

Sunday saw me head to the Lakeland Fells for some walking and a spot of testing of my new Pentax K10D. The details of the walk itself are not for here but for my hillwalking blog and that is where you will find them. While making my way from Crewe to Windermere, I perused the manual looking particularly for information pertaining to functions that I actually use, I should really have done this beforehand, but distractions meant that I hadn’t got around to it. I had to wade through something designed for a new SLR user before I got to what I consider the important stuff. Though this may be a bit irritating, I can understand and accept why they do it this way; we were all new users once and they are hardly likely to want to know about things like aperture priority, raw file capture, ISO control and such like straight away.

What do I think of it then? Let’s start with first impressions. It is definitely smaller than the Canon EOS 10D it accompanies in my possession. That said, it is not too small and there is a decent grip hosting the shutter release button and the camera on/off switch. It also feels well-assembled and reassuringly weighty, an important consideration given that it will see the outdoors a lot. A discussion of the features most relevant to me follows.

On the subject of switching on and off, the camera is set to go into a sleep mode after a second of inactivity but it reawakens quickly when needed, the trigger being half-depression of the shutter release button. In fact, the camera does reawaken much faster than my Canon as it happens and where the delay is a constant source of some irritation. It might sound strange but the on/off switch is also used to activate the depth of field preview, something that no SLR should not have. The location may be unusual, but maybe the designers thought that having shutter release and depth of field preview next to each was a logical way to do it. From a camera operation point of view, there is certainly something to that way of thinking. Behind the shutter release, you’ll find a screen that is a reminder of film SLR’s and it conveys information such as battery life, number of exposures remaining on the card and exposure details (aperture & shutter speed).

Staying on the subject of screens, the one on the back of the camera is larger than that on the Canon. As is customary for these, it allows replay of photos taken and access to the various menus required to control the camera’s operation. In comparison to the Canon, which is essentially a one menu affair with a thumb wheel controlling scrolling and an OK button at its centre to perform operations, the Pentax has a more elaborate system of submenus: one each for recording, playback and set-up. The playback menu is where I found the setting that makes the camera highlight areas of underexposure and overexposure during image playback. This is something that I missed with respect to the Canon until I happened upon it. Camera cleaning is located on the set-up menu and the camera is now set to clean the sensor every time that it is turned on. Why this is not enabled by default is a little beyond me, but the designers might have thought that a vibration from the camera on turning it on could have resulted in a load of support calls. The same submenu also hosts memory card formatting. The recording submenu is where I set the camera to deliver RAW DNG files, an Adobe innovation, rather than the default JPEG’s. There are other options like RAW PEF files, Pentax’s own format, or RAW and JPEG simultaneously, but my choice reflects my workflow in Photoshop Elements; I have yet to stop the said software editing the DNG files, however. With all these options, it is fortunate that there is a navigation wheel whose operation uses arrow buttons to get about. While on the subject of the back screen, there are further settings that are accessed with the FN button rather than the Menu one. These include ISO, white balance, shooting mode (single, continuous, timed and so on) and flash. The only setting that I changed out of this lot was to set the ISO to 400; I prefer to feel that I am in control.

Returning to the camera’s top plate, the exposure mode dial is on the left-hand side, which is no hardship to me as this is in the same place as on the Canon. There are no scene modes, but the available exposure modes are more than sufficient: fully automatic, program, sensitivity priority, shutter priority, aperture priority, shutter and aperture priority, manual, bulb and external flash synchronisation. A few of these need a spot of explaining. Sensitivity priority is no one on me but it is a consequence of the ability of DSLR’s to offer a range of ISO settings; the aperture and the shutter speed are varied according to the ISO setting. Shutter and aperture priority is like manual exposure and is the inverse of sensitivity priority: set both aperture and shutter speed, and the camera will vary the ISO setting. Both of the foregoing assume that you let the camera set the ISO but my setting the thing myself may have put paid to these functions. Shutter priority and aperture priority are, as far as I can tell, their usual selves. For all exposure modes, the thumb wheels at the front and back of the shutter release handgrip set apertures and shutter speeds where appropriate and this arrangement works well.

Mounting on the same column as the exposure dial the metering mode selector and here is where I see more options than my Canon, which has only full and partial multi-segment metering. With the Pentax, you get spot and centre-weighted metering in addition to the default multisegmented variety. Spot metering is definitely very useful but capturing the reading is a multitasking affair: half pressing the shutter button and fulling pressing the AE lock one at the same time. In contrast, Canon’s partial metering is a more convenient single button operation meter and retain facility. Pentax would do well to learn from this.

The focussing mode selector is found on the left of the body next to the lens coupling. I am used to having this on the lenses themselves, so this is a new arrangement for me and one to which I can easily become accustomed. In fact, it is easy to find it while composing a picture. The modes themselves are manual focus, one-time autofocus and continuous autofocus; the last of these is for focussing on moving objects.

I could go further, perhaps overboard, with a discussion of the features of this camera but I draw a line at what’s here. Yes, it is useful to set the focussing point and activate image stabilisation but the above are what matter to me and its performance in the photo making department is the most important aspect. That neatly brings me to my appraisal of how it performs. With inspection of the first few images on the review screen, I was a little disappointed to see how dark the foreground was in comparison to the sky. When I brought everything home as I always do, I found that things weren’t necessarily as they appeared in the field. The Pentax more usefully offers histogram review and highlighting of any areas that are either underexposed or overexposed. It is these functions that I will be using in reshooting decisions while out and about with the Pentax and the same can be said for how I currently use the Canon. In fast changing lighting, the AE lock technique was a bit irritating but I am certain that I will get better at it. The autofocus doesn’t always lock onto the subject, especially in tricky lighting, so manual focussing is a definite necessity and is more useful more for landscape photography, in fact. Nevertheless, the autofocus did do well most of the time and my Sigma lenses have done worse things on me. All in all, I am happy with the K10D and will continue to use it. I have got some decent photos from my excursion and that, as that Jessops salesman would agree, is the main point of a camera.

Amateur Photographer reviews…

19th July 2007

Amateur Photographer seem to have had a run of reviews recently. First off were the Olympus E-410 and E-510 that they seemed to like. Then, they moved onto the Ricoh Caplio GX100 and they seemed to like that too, though they did say that quality wasn’t up to SLR standards. But then again, it is a compact and that might be expecting a bit too much. This week, Paint Shop Pro comes under the spotlight as does Epson’s V350 scanner. I have yet to read these but I have been engaging in a spot of equipment acquisition anyway. My CanoScan 5000F scanner has been usurped by Epson’s Perfection Photo 4490 and very happy I am with it too. The quality of the scans that I have been doing of prints has been good and the presence of an on/off switch is a creditable one. None of the other scanners that I have had possessed it and having to plug something in and out from the power socket is inconvenient to say the least. I have also gone and got myself a new DSLR. Seeing Pentax’s K10D going with a 18-55 mm lens for £499 at Jessop’s overrode my better reason and put paid to ideas of purchasing any other electronic goods for the rest of this year. It’s an award-winning gadget and Photography Monthly’s Will Cheung seemed to get on fine with it. Which Digital Camera said it was heavy but it has to stand up to use in the great outdoors. The sensor may be a 10 megapixel affair so this will be an upgrade to my Canon EOS 10D; that has a sensor in need of clean right now (I plan to get it done by the professionals) and every time that I want to use an image that it has made, Photoshop’s healing brush has to be pressed into service. Pentax does boast about all of the seals that it has added to the K10D, a good thing if they cut down on the dust entering the camera. And if dust does get in, the sensor cleaning feature will hopefully see it off from the photos. Image stabilisation, another value adding feature, is also there and may prove interesting. Strangely, there’s some motion picture capture as well and I hope that it doesn’t get the EU coming after me to collect retrospective camcorder duty. In any case, it’s not a feature that I really need and the Live View functions on the equivalent Olympus offerings fall into the same category anyway. It’ll be interesting to see how the K10D performs and it’s a change from the Canon/Nikon hegemony that seems to dominate digital photography these days.

Pentax K10D

Update: I have since perused the current issue of Amateur Photographer and seen that Paint Shop Pro suffered from performance issues on computers that worked fine with Photoshop. Otherwise, it compared well with Adobe’s offerings even if the interface wasn’t seen to be as slick. Epson’s V350 was well received though it was apparent that spending more got you a better scanner but that’s always the way with these things.

Another Olympus E-system review

27th June 2007

Olympus E-510

I don’t buy Amateur Photographer much these days but sight of a review of Olympus’ E-410 and E-510 SLR’s got a copy into my possession. Amateur Photographer review features are usually comprehensive and this was no exception; there was none of the vitriol directed towards the Live View feature by Practical Photography, a defining feature of what i consider a lop-sided and none too useful review. The verdict was a positive one in the main with the E-510 getting the nod over the E-410 because it fared better on the usability side of things. Image quality, my major concern, was said to be impressive with only dynamic range counting against the results. The Live View feature didn’t attract the harsh commentary devoted to it by Practical Photography. Following this review, I have to say that the E-510 does tempt me with its combination of good image quality, dust removal and image stabilisation.
