Adventures & experiences in contemporary technology

Two versions ago…

26th March 2007

With all the focus that there is on the current version of a long established piece of software, it is often intriguing to see what it was like a few versions back. And it was with that curiosity that I had a look at PhotoShop 7. Needless to say, a lot of the functionality of the current version is there: adjustment layers, saving for the web and so on. That said, I did spot some absences as one would expect. For instance, the file browser, dropped down by a tab on the main interface, had yet to morph into the standalone Adobe Bridge. Another change has been the resampling choices for resizing; there is no sign of the now prevalent bicubic smoothing and bicubic sharpening. On the filters menu, there is no sign of Smart Sharpening, the now recommended sharpening technique that upstages the one time favourite Unsharp Mask. These may appear little things but little things are often the very items that persuade you that an upgrade is a very good idea.

Is Photoshop CS3 imminent?

16th March 2007

We have seen the beta come out, an unprecedented move for Adobe, and now we are hearing about the new professional editions of Photoshop: Photoshop CS3 for digital imaging and Photoshop CS3 Extended with tools for processing digital video. Together with Photoshop Lightroom for digital photography and Photoshop Elements for the consumer market, it seems that Photoshop is moving from a single application to becoming a big family of them. Adobe is hosting an online launch for the CS3 suite on March 27th so the appearance on the market of the new Photoshop must be very imminent. In the light of this, I think I’ll hold off on a decision to purchase either Elements 5 or its CS2 until I have tried out the latter’s successor.

Update: I’ve just perused both  .Net’s and Advanced Photoshop’s initial appraisals of Photoshop CS3 and they seemed impressed so it should be worth a look then. Another tempting idea is to have a taste of Lightroom so I went and downloaded the 30-day trial version. I may well have a go with it in my own time; I’m not wanting to install it and let the 30 days run out before I get to use it in anger.

More thoughts on learning to use digital imaging software

14th March 2007

If you ever go into a bricks and mortar newsagent and peruse its shelves with an eye out for references to data imaging software, you might find Adobe’s Photoshop as predominant there as it is in the digital imaging world. And the same trend seems to continue in to the bricks and mortar bookshops as well. Online, especially within the vaults of Amazon, it is not as much a matter of what gets stocked as what gets published and my impression is that the bias, if that’s the right word, continues there. That said, I didn’t realise until recently that Elsevier’s Focal Press has been covering Paint Shop Pro, once branded the poor man’s Photoshop, from at least version 7. That discovery, if it had come earlier, may have made a big difference to how I have been using PSP. That said, I have seen some opinions that PSP is easy to use and that may explain the lack of attention from publishers. Future Publishing did put out a monthly guide to PSP but that seems to have disappeared from the shelves and it does lend weight to that argument. Or it could have been Corel’s purchase of JASC that changed things…

Of course, without books and magazines, it is not as easy to see the possibilities and it is here where Photoshop really scores. The digital photography revolution has ensured the software’s escape from the world of computing and the digital arts into photography magazines and beyond. These days, even conventional photography titles feature Photoshop how-to articles. In fact, such is the level of digital content in titles such as Photography Monthly, Practical Photography and Outdoor Photography that you hardly need to pursue the specialist digital photography titles at all.

Speaking of photography, this is and has been my main use of digital imaging technology, be it the scanner that I use for digitising the output of my efforts in film photography or processing RAW files from my digital SLR. I have been using scanners since 1998 and am on my second, a CanoScan 5000F. The colour rendition in the output from its predecessor, a UMAX 1212U, deteriorated to the point where a replacement needed to be sought. As it happened, the Canon proved to be light years ahead of the UMAX, even with the latter operating properly. Incidentally, my first scanning outing was in the then current version of Photoshop (I booked some time on a scanner at the graphics centre of the university I was attending at the time and sneaked in the scanning of a photo with the journal graphic that I needed to do) -- a limited affair, it has to be said -- but I then reverted to things like Corel PhotoPaint and Paint Shop Pro. And PSP was what I was using in the main even after encountering the copy of Photoshop Elements 2 bundled with my EOS 10D. Elements’ cloning capabilities did tempt me though and I did acquire a Focal Press volume on the application but I somehow never took it further.

At the end of last year, Corel and Adobe launch new versions of PSP and Elements, respectively. That got me tempted by the idea of giving the whole business another look, this time in detail. My look at PSP XI regrettably suffered from the lack of time that I could devote to it and seeing what a book on it might have to say. I had more of a chance with Photoshop Elements and came away impressed with the way that it worked. Since then, I have been making my way through Scott Kelby’s latest Elements book and the ideas are building up. At the same time, I have been making good use of a Photoshop CS2 try-out and I am on the horns of a dilemma: do I splash out on CS2, do I get Elements 5 or do I await the now imminent CS3? You’ll notice that PSP doesn’t feature here; the amount of literature pertaining to Photoshop simply is too much to ignore and I have loads more to learn.

Photoshop CS2 workout

8th March 2007

Adobe Photoshop CS2

I am in the process of adding new photos to my online photo gallery at the moment and the exercise is giving my Photoshop CS2 trial version a good amount of use. And the experience also adding a few strings to my bow in graphics editing terms, something that is being helped along by the useful volume that is The Focal Easy Guide to Photoshop CS2.

The most significant change that has happened is that to my workflow. Previously, it took the following form:

  • Acquire image from scanner/camera
  • For a camera image, do some exposure compensation
  • Create copy of image in software’s own native file format (PSPIMAGE/PSP for Paint Shop Pro and PSD/PSB for Photoshop)
  • Clean up image with clone stamp tool: removes scanner artefacts or sensor dust from camera images; I really must get my EOS 10D cleaned (the forecast for the coming weekend is hardly brilliant to I might try sending it away).
  • Save a new version of the image following clean-up.
  • Reduce the size of the digital camera image to 600×400 and create a new file.
  • Boost colours of original image with hue/saturation/lightness control; save new version of file.
  • Sharpen the image and save another version.
  • For web images, save a new file with a descriptive name
  • Create JPEG version
  • Copy JPEG to Apache web server folders
  • Create thumbnail from original JPEG

The new workflow is based upon this:

  • Acquire image from scanner/camera
  • For a camera image, do some exposure compensation; there is a lot of pre-processing that you can do in Camera Raw
  • Create copy of image in software’s own native file format
  • Clean up the image with the clone stamp tool and create a new file with _cleaned as its filename suffix. I tried the spot healing brush but didn’t seem to have that much success with it. Maybe I need to try again…
  • Add adjustment layer for level correction and save file with _level suffix in its name.
  • Add adjustment layer for curves correction
  • Add adjustment layer for boosting colours with hue/saturation/lightness control
  • Flatten layers and save new image with _flatten suffix in its name
  • Sharpen flattened image and create a new version with _sharpened suffix in its name
  • For web images, save a new file with a descriptive name
  • Create JPEG versions in Apache web server folders; carry out any resizing using bi-cubic sharpening at this point.

Some improvements remain. For instance, separation of raw, intermediate and final photos by storing them in different directories is perhaps one possibility that I should consider. But there are other editing tricks that I have yet to use as well: merged and blended layers. Bi-cubic smoothing for expanding images is another possibility but it is one that requires a certain amount of caution. And I am certain that I will encounter others as I make my way through my reading.

Photoshop books

28th February 2007

Having exhausted the trial time on PhotoShop Elements 5, I am now having a look at its big brother PhotoShop CS2. That has got me thinking about PhotoShop books so that I become more of the possibilities and how to use them. Having a Safari subscription as I do, that naturally became my first port of call and I seemed to find two that answered my needs. Both are by Scott Kelby and they now lie on my Safari bookshelf: The Photoshop Elements 5 Book for Digital Photographers and The Photoshop CS2 Book for Digital Photographers. Even so, I am tempted to get a dead tree version of one of them and that presents a chicken and egg dilemma: the books could help choose which software to buy and the software dictates which of them will be the more useful. That said, I suspect price and features will swing it the way of Elements 5; paying over £400 for software whose capabilities I may never need does not sound financially sensible.

Update March 5th, 2007: I have now got my mits on the dead tree edition of Scott Kelby’s The Photoshop Elements 5 Book for Digital Photographers as well as Brad Hinkel’s Focal Easy Guide to Photoshop CS2. Now for some reading…

PSP file gotcha

29th January 2007

Corel Paint Shop Pro Photo XI

Having completed my evaluation of Corel’s Paint Shop Pro (a.k.a. PSP) Photo XI, I dutifully uninstalled it from my system. However, on catching up with some files that I had acquired through the application, I found that I could not open them with its forbear PSP 9. From this, I would have to conclude that Corel made a change to PSP’s native PSPIMAGE file format along the way. Having had Windows 2000 installed in a VMware virtual machine, I got back PSP XI to batch convert the files into PSD (Photoshop’s own file format) and TIFF files for the future. Carrying out the conversion was easy enough thanks to being able to select files according to their file type, something that Adobe could do with bringing into Photoshop Elements; it’s not there even in the latest version.

Batch processing with Corel Paint Shop Pro Photo XI

Photoshop Elements 5 on trial

Photoshop Elements 5 on trial

After having a trial version of Corel’s Paint Shop Pro Photo XI on evaluation, I have now moved on to the latest version of Adobe’s Photoshop Elements. Thanks to the digital photography revolution, image editing has become a lot more user-friendly these days. This is no doubt down to companies realising that investing in the development of this class of software does yield a return and the development effort is progressing things very nicely indeed.

My first exposure to image editing was with Corel’s PhotoPaint, a low profile application that did what I asked of it while guzzling as much of what little memory my PC had in those days (32 MB first, then 64 MB). Paint Shop Pro 5, a popular tool of shareware origins, replaced this, though I must admit that I did briefly encounter the ubiquitous Photoshop at this stage. The PSP commitment continued through versions 7 and 9; though it is only in the later versions that photo processing began to be a significant part of the functionality. PSP XI has taken this further and has add-on tools like SnapFire for downloading photos from cameras. It does feature screen calibration as well but I found that photos appeared very pale when using the calibrated workspace; maybe I set it up wrong. That said, its assistance in setting the brightness and contrast of my monitor was most useful. Until then, I hadn’t realised the details that I had been missing.

Nevertheless, Adobe’s Photoshop Elements has been able to inspire a certain level of confidence that PSP doesn’t. Even PE 2, which I got bundled with my Canon EOS 10D SLR, had that little extra when compared with PSP 9. For instance, it was PE where I saw the real power of the clone stamping tool. That different in air of confidence also extends to the latest generation. I have found PE 5 very quick and easy to generate good results. Features like the levels tool and “Save for the Web” are things that I have found very useful. There are a few minor disappointments such as its not showing the pixel size of the image being edited, a very useful feature of PSP. A bit of clarity around image resizing would also be nice but I suspect that I may just need to learn a little more. Overall, its speed when it comes to creating nice results swings me away from PSP and may ultimately put paid to any loyalty that I may have had to Corel’s image editor for the masses. I think that I’ll have a go with its big brother but it looks as if I may well acquire PE 5 on a more permanent basis.
