Technology Tales

After a session with Photoshop CS2 and a preview of CS3’s capabilities, I went and got myself a permanent copy of Elements 5 after seeing the similarities between Scott Kelby’s books on Elements 5 and CS2. In any event, I fail to justify the cost of CS2 with CS3 being imminent and the attractions of Elements 5 were too much to ignore. I may yet go for CS3 but I’ll stick with Elements 5 for now.

The similarities between the different members of the PhotoShop family are eerie. Once I got used to finding some things in different places from where they are in CS2, I quickly found myself at home in Elements. The biggest miss that I found was the lack of an adjustment layer for the curves adjustment. Otherwise, everything else is as I would hope to find it and the sliders for curves adjustment in Elements make up for the absence of an associated adjustment layer. Bicubic resampling, an enhancement since Photoshop 7, is as per CS2 and my new workflow worked without too many changes. I took advantage of Kelby’s advice when using Camera Raw and used the Adjust Sharpness feature in place of the Unsharp Mask to get what I perceive to be good results. Everything seemed to work fine for the test digital photo that I was processing for my other blog. I am not totally abandoning my examinations of Elements’ big brother though; the smart layers feature looks interesting, especially for non-destructive sharpening.

Last night, I sat through part of Adobe’s CS3 launch and must admit that I came away intrigued. Products from the Macromedia stable have been very much brought under the Adobe umbrella and progressed to boot. One of these that attracts my interest in Dreamweaver and Adobe is promoting its AJAX capabilities (using the Spry library), its browser compatibility checking facility and integration with Photoshop, among other things. Dreamweaver’s CSS support also gets taken forward. In addition, Dreamweaver can now integrate with Adobe Bridge and Adobe Device Central. The latter allows you to preview how your site might look on a plethora of WAP-enabled mobile phones while the latter, unless I have been missing something, seems to have become a media manager supporting all of CS3 and not just Photoshop.

Speaking of Photoshop, this now gets such new features as smart filters, I think of these as adjustment layers for things like sharpening, monochrome conversion and much more. Raw image processing now has a non-destructive element and Photoshop Lightroom is being touted as a companion for the main Photoshop. Speaking of new additions to the Photoshop family, there is a new Extended edition for those working with digital imaging with a 3D aspect and this is targeted at scientists, engineers, medical professionals and others. It seems that data analysis and interpretation is becoming part of the Photoshop remit now as well.

Dreamweaver and Photoshop are the components of the suite in which I have most interest but I also note that Contribute now has blogging capabilities; it would be interesting to see how these work, especially given Word 2007’s support for blogging tools like WordPress and Blogger. Another member of note is Version Cue, adding version control to the mix and making CS3 more like a group of platforms than collections of applications.

Unsurprisingly, the changes are rung out for the rest of the suite with integration being a major theme and this very much encompasses Flash too. The sight of an image selection being copied straight into Dreamweaver was wondrous in its own way and rendering of Photoshop files into 3D images was also something to behold. The latter was used to demonstrate the optimisations that have been added for the Mac platform, a major selling point apparently.

I suppose that the outstanding question is this: do I buy into all of this? It’s a good question because the computer enthusiast seems to be getting something of a sidelining lately. And that seems to the impression left by Windows Vista in its giving the appearance that Microsoft is trying to be system administrator to the world. There is no doubt but CS3 is very grown up now and centred around work flows and processes. These have always been professional tools and the present level of sophistication and pricing* very much reflects this. That said, enthusiasts like me have been known to use them too, at least for learning purposes. The latter point may yet cause me to get my hands on Photoshop CS3 with its powerful tools for digital imaging but Dreamweaver is another story. It doesn’t fit what how I work now so this is an upgrade that I may give a miss, as impressive as it looks. For a learning experience, I might download a demo but that would a separate matter from updating my web presence. This time next month may tell a tale…

*Pricing remains the bugbear for the U.K. market that it always has been. At the present exchange rates, we should be getting a much better deal on Adobe products that we do. For instance, Amazon.com has the Web Premium CS3 suite from Macromedia Studio 8 priced at $493.99 while it is £513.99 on Amazon.co.uk. Using the exchange rate current as I write this, £1 buying $1.96605, the U.K. price is a whopping $1010.53 in U.S. terms. To me, this looks like price gouging and Microsoft has been slated for this too. I wonder what will be said to Adobe on this one.

Having been on a web-building journey from Geocities to having a website with my own domain hosted by Fasthosts, it should come as no surprise that I have encountered a number of tools and technologies over this time and that my choices and knowledge have evolved too. I’ll muse over the technologies first before going on to the tools that I use.

Technologies

XHTML

When I started building websites, HTML 4 was not long in existence and I devoured most if not all of Elizabeth Castro’s Peachpit Visual Quickstart guide to the language within a weekend. Having previously used fairly primitive WYSIWYG tools like Netscape Composer and Claris Home Page, it was an empowering experience and the first edition (it is now on its third) of Jennifer Niederst Robbins’ Web Design in a Nutshell took things much further, becoming something of a bible for a number of years.

When it first appeared, XHTML 1.0 wasn’t a major change from HTML 4, but its stricter more XML-compliant syntax was meant to point the way to the future and semantic markup was at its heart at least as much as it was for HTML 4. XHTML 2.0 is on the horizon and after the modular approach of XHTML 1.1 (which I have never used), it will be interesting to see how it develops. Nevertheless, there is a surprising development in that some people are musing over the idea of having an HTML 5. Let’s hope that the (X)HTML apple cart doesn’t get completely overturned after some years of relative stability. I still bear scars from the browser wars raging in the 1990’s and don’t want to see standards wars supplanting the relative peace that we have now. That said, I don’t mind peaceful progression.

CSS

Only seems to be coming into its own in the last few years and is truly an amazing technology in spite of the hobbles that MSIE places on our ambitions. CSS Zen Garden has been a major source of ideas; I wouldn’t have been able to customise this blog as much as I have without them. I was an early adopter of the technology and got burnt by inconsistent browser support; Netscape 4 was the proverbial bête noir back then, fulfilling the role that MSIE plays today. In those days, it was the idea of controlling text display and element backgrounds from a single place that appealed. Since then, I have progressed to using CSS to replace table-based layouts and to control element positioning. It can do more…

JavaScript

Having had a JavaScript-powered photo gallery before my current Perl-driven one, I can say that I have definitely sampled this ever-pervasive scripting language. Being a client-side language rather than a server-side one, it does place you rather at the mercy of the browser purveyors and it never ceases to amaze me that there is a buzz around AJAX because of this. In fact, the abundance of AJAX cross-browser function libraries is testimony to the need for browser-specific code. Despite my preferences for server-side scripting, I still find a use for JavaScript and its main use for me these days is to dynamically control CSS elements to do such things as control the height of a page element or whether it is shown or not. Apparently, CSS may get some dynamic capabilities in the future and reduce my dependence on JavaScript. In the meantime, Jeremy Keith’s DOM Scripting (Friends of Ed) will prove as much of an asset as it has done.

XML

These days, a lot of the raw data underlying my personal website is stored in XML. I did try to dynamically transform the display of the XML into something meaningful with CSS and XSLT when I first scaled its dizzy heights but I soon resorted to other techniques. Browser support and the complexity of what I required were the major contributors to this. The new strategy involved two different approaches. The first was to create PHP/XHTML pages from the precursor XML offline and this is how I generate the website’s directory pages. The other one is to process the XML as text to dynamically supply an XHTML page as the user visits it; this is the way that the photo gallery works.

Perl

This still powers all of my photo gallery. While thoughts of changing it all to PHP linger, there is a certain something about the Perl language that keeps it there. I suppose it is that PHP is entangled in the HTML while Perl encases the whole business and I am reasonably familiar with its syntax these days which is why it still does a lot of the data processing grunt work that I need.

PHP

PHP is everywhere these days, though it doesn’t attract quite the level of hype that used to be the case. It still appears with its sidekick MySQL in many website applications. Blogging software such as WordPress and content management systems like Drupal, Mambo and Joomla! wouldn’t exist without the pair. It appears on my website as the glue that holds my visitor directories together and is the processing engine of my WordPress blog. And if I ever get to a Drupal element to the site, by no means a foregone conclusion though I am spending a lot of time with it at the moment, PHP will continue its presence in my website scripting as it powers that too.

Applications

Macromedia HomeSite

I have a liking for hand coding, so this does most of what I need. When Macromedia (itself since taken over by Adobe, of course) took over Allaire, HomeSite sadly lost its WYSIWYG capability, but the application still soldiers on even though Dreamweaver offers a lot to code cutters these days. Nevertheless, it does have certain advantages over Dreamweaver: it is a fleeter beast to start up and colour codes Perl syntax.

Macromedia Dreamweaver

There was a time when Dreamweaver was solely a tool for visual web page development, but the advent of Dreamweaver UltraDev added server-side development capabilities to the Dreamweaver family. These days, there is only one Dreamweaver version, but UltraDev’s capabilities still live on in the latest version and I would not be surprised if they were taken further in these database-driven times.

Nowadays, Dreamweaver isn’t an application where I spend a great deal of time. In former times, when my site was made up of static HTML pages, I used Dreamweaver a lot even if its rendering capabilities were a step behind the then-current browser versions. I suppose that it didn’t fit the way in which I worked, but its template-driven workflow would have been a boon back then.

However, my move from a static site to a dynamic one, starting with my photo gallery, has meant that I haven’t used it as much since then. However, with my use of PHP/MySQL components on my site. Its server-side abilities could get the level of investigation that its PHP/MySQL capabilities allow.

Altova XMLSpy Professional

Adding MySQL databases to my web hosting costs money, not a lot but it could be spent on other (more important?) things. Hence, I use XML as the data store for my photo gallery and XML files are pre-processed into XHTML/PHP pages for my visitor directories prior to uploading onto the server.

I use XMLSpy to edit and manage the XML files that I use: its ability to view XML in grid format is a killer feature as far as I am concerned and XML validation also proves very useful; particularly with regard to ensuring that DTD’s and XML files are in step and for the correct coding of XSLT files. There are other features that I need to explore and that would also take my knowledge of the XML further to boot, not at all a bad thing.

Saxon

For processing XML into another file format such as XHTML, you need a parser and I use the free version of Saxon to do the needful, Saxonica offers commercial versions of it. There is, I believe, a parser in XMLSpy but I don’t use it because Saxon’s command line interface fits better into my workflow. This is a Perl-driven process where XML files are read and XSLT files, one per XML file, are built before both are fed to Saxon for transforming into XHTML/PHP files. It all works smoothly and updating the XML inputs is all that is required.

AceFTP

If I were looking for an FTP client now, it would be FileZilla but AceFTP has served me well over the last few years and it looks as if that will continue. It does have some extra features over FileZilla: transfers between remote sites, and scheduling, for example. I have yet to use either but they look valuable.

Hutmil

In bygone days when I had loads of static HTML files, making changes was a bit of a chore if they affected every single file. An example is changing the year on the copyright message on the page footers. Hutmil, which I found on a magazine cover-mounted disc, was a great time saver in those days. Today, I achieve this by putting this information into a single file and getting Perl or PHP to import that when building the page. The same “define once, use anywhere” approach underlies CSS as well and scripting very usefully allows you to take that into the XHTML domain.

Apache

Apache is ubiquitous these days and both the online and offline versions of my site are powered by it. It does require some configuration but it is a very powerful piece of kit. The introduction of 2.2.x meant a big change in the way that configuration files were modularised and while most things were contained in a single file for 2.0.x, the settings are broken up into different files in 2.2.x and it can take a while to find things again. Without having it on my home PC, I would not be able to use Perl, PHP or MySQL. Apart from this, I especially like its virtual site capability; very useful for offline development.

WordPress

My hosting supplier offers blogs on Blogware, but that didn’t offer the level of configuration that I would have liked. It is true that this is probably true of any host of blogs. I can’t speak for Blogger but WordPress.com does have its restrictions too. To make my hillwalking blog fit in with the appearance of my photo gallery, I went popped over to WordPress.org to download WordPress so that I could host a blog myself and have maximum control over its appearance. WordPress supports themes so I created my own and got my blog pages looking as if they are part of my website, rather than looking like something that was bolted on. Now that I think of it, what about WordPress supporting user-created themes? I support that there is the worry of insecure PHP code but what about it?

MySQL

I am between minds on whether this is a technology or a tool. SQL certainly would be a technology standard but I am not so clear on what MySQL would be. In any case, I have classed it as a tool and a very useful one at that. It is the linchpin for my WordPress blogs and, if I go for a content management system like Drupal, its role would surely grow. While I do have a lot of experience with using SAS SQL and this helps me to deal with other varieties, there is still a learning curve with MySQL that gets me heading for a good book and Kofler’s The Definitive Guide to MySQL5 (Apress) seems to perform more than adequately in this endeavour.

Paint Shop Pro

As someone who hosts an online photo gallery, it won’t come as a surprise that I have had exposure to image editors. Despite various other flirtations, Paint Shop Pro has been my tool of choice over the years, but it is now set to be usurped by a member of Adobe’s Photoshop family. Paint Shop Pro does have books devoted to it but it seems that Photoshop gets better coverage and I feel that my image processing needs to be taken up a gear, hence the potential move to Photoshop

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.

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.
