Here’s a question which came in to my email just now:

“Could I process a RAW file in Photoshop to achieve a similar effect as if I had used a Polaroid lens filter?
Or would I be better just using the Polaroid filter?”

The answer is that you can never imitate the effect of polarizing light (which changes the way reflective surfaces look, and deepens or lightens the sky blue according to the zone of the sky relative to the sun’s position. But you can use Adobe Camera Raw (CS3 versions) to deepen skies you never thought could be rescued.

The introduction of a £399 (street price, RRP £449) DSLR with 14.2 megapixels – with or without a useful type of Live View – should have been applauded by reviewers. It’s the single most important point about the camera. No other DSLR approaches this image size and resolution at such a low price.

CLICKING on key mapping points of a face, then adjusting some simple overlaid Bezier curves using movable anchors, it takes only a minute to load a typical headshot portrait into Portrait Professional.

Now that there are five Sony Alpha DSLR bodies in circulation, with many owners of the original 2006 Alpha 100 considering a replacement, the differences between this ur-Alpha and the 2007-8 generation of Alpha 700, 200, 300 and 350 need examining.

Epson has today launched an innovative new print plug-in for the Adobe Photoshop family of products that provides users with enhanced functionality and flexibility, making colour-managed printing quicker and easier.

London— April 2, 2008 — Adobe Systems Incorporated (Nasdaq: ADBE) today announced Adobe Photoshop Lightroom 2.0 beta, a public preview of new and improved functionality to be delivered in the next major release. Lightroom is the professional photographer’s essential toolbox, providing one application for managing, adjusting, and presenting large volumes of digital photographs. Lightroom 2.0 beta will feature enhancements such as dual-monitor support, localised dodge and burn correction and will be the first Adobe application to support 64-bit for Mac OS X 10.5 Intel Macs and Microsoft Vista 64-bit operating systems.

Adobe has released updates to Photoshop Lightroom and the Photoshop Camera Raw plug-in, both available immediately as free upgrades for existing users. The releases provide added raw file support for nine additional digital cameras, including the Sony Alpha 200 (already supported by 4.3.2 whether they knew it or not), Alpha 300 and Alpha 350. Lightroom 1.4 also provides updated printer driver compatibility for Apple Leopard Mac OS X 10.5.

The Sony Alpha 350 14.2 megapixel DSLR pioneers a new type of Live View, related to Olympus’s original Mode A of the E-330 where a beamsplitting arrangement allowed a video CCD to view the actual focusing screen of the SLR system.

There’s a lot of controversy right now about whether or not the image structure of the Alpha 700 files at very high ISO - mainly 3200 and 6400 - is as clean as raw processed results from other comparable cameras like the Canon 40D (does not offer ISO 6400), the Olympus E-3 (does not offer ISO 6400) or the Nikon D300. At the heart of this is the way different raw processors handle file conversion, and most specifically, the current performance of Adobe Camera Raw 4.3.1.

The Sony DSLR A200 is now on sale, following the end of Alpha 100 production. Although it is without any doubt the Alpha 100 replacement mentioned by Sony executives in October 2007, when they first revealed that the 100 was no longer being made, it is not an exact equivalent and represents a mixture of upgraded performance and simplified specification. Because it has gone in two directions at the same time, the A200 poses a problem for A100 owners.

Apple’s Aperture 2.0 is a tedious program to test, with all its creation of ‘projects’ and ‘libraries’, ‘albums’, ‘vaults’ and nonstandard GUI, and it isn’t fast in processing files or passing them to Photoshop (which it does in 16-bit form, just another step to reverse before saving as far as I’m concerned). However, it’s handling Alpha 700 raw quite well. And it does things differently, with non-destructive raw editing, stacks of image versions, and so on.

The latest full release - no longer Beta, and accepting previous C1 Pro activation keys for unlimited access but otherwise now on 30-day trial - of Capture One v4 now handles Sony Alpha 700 raw files and transforms high ISO rendering in comparison to the industry standard Adobe Camera Raw.

On January 5th, Photoworld was lucky enough to be able to attend the dress rehearsal and official photo-call for the new Cirque du Soleil production at the Royal Albert Hall in London, and to put the Alpha 700 through its paces for high ISO fast action stage show capture. This article with large reproductions of the images appears in our Photoworld issue due out later in January.

AT THE Consumer Electronics Show, Las Vegas, Sony has announced introduction of the new Alpha DSLR-A200 camera which has been the subject of some strange speculation but was known beforehand to be a replacement for the Alpha 100. This is the first time a DSLR has been launched to the world at this show, and Sony’s decision to do so sends a major signal out as to where they see themselves and the Alpha system in the marketplace. It is highly competitive in price and we have just ordered our body for £369 including VAT (£314 + VAT) plus £13 express shipping from www.sonystyle.co.uk. This is exactly the same price as we paid for our last Alpha 100 in summer 2006.

After reading Andrea Nivini’s article in Italian Tutti Fotografi, December 2007, which launches an attack on Adobe’s Camera Raw plug-in and its handling of many camera types - but specifically, the Sony Alpha 700 - I decided to check out whether the December 5th release, ACR 4.3.1, fixed the problems.

It’s the same on every web forum - if you post a digital picture which would be acceptable to a photo library or professional buyer, half a dozen grumpy one-liners will come out saying ‘That don’t look sharp to me’ or ‘there must be something wrong with your XXX’ (fill in D300, A700, E-3, D3, 40D as required). Then someone posts a hugely messed up image and people say ‘Wow! What sharpness!’…

OUR local dealer, Hector Innes in Kelso, used to be a totally Minolta-dedicated retail shop. Hector and his son Alastair have always been Minolta photographers, and Alastair currently uses the Dynax 7D as weapon of choice for weddings. Their shop is one of those few remaining which combines a professional studio (ABIPP, in Hector’s case) with processing and printing, and retail. On the wall there’s a Minolta clock from two or three changes of logo ago, and on the counter, I found a well-used and yellowed Minolta lens chart mat.

I HAVE set up a pBase gallery with a large number of comparison studio shots, all the way from ISO 100 to the maximum, using the A700 and Nikon D300. It has some minor discrepancies in shooting conditions which I need to explain to anyone visiting the gallery.

LET’S not get too acronymical about all this… or indeed moanious! After posting today’s earlier piece on DRO Advanced, I’ve been asked for some further examples of the potential for processing the raw file using Sony Image Data Converter, which includes DRO. Or so it says on the box.

Sony has released a firmware update for the Alpha 700, from version 1.00 (as supplied) to version 2.00, and an updater for Image Data Converter 2.0 SR.

I’m still testing the Alpha 700 and still struggling with aspects of image quality, notably the failure to get much wow factor from straightforward shots in good light. It seems easy enough to get exceptional high ISO images, of the type they are expected to be, but even then many examples seen are marred by a very coarse noise structure.

ON OCTOBER 10th I left the UK London press launch complete with an Alpha 700 review camera. I’ll be covering the many aspects of the Alpha 700 performance in later reviews, but this camera is so good I wanted to get just something out to you right the next day.

THE ALPHA 700 cameras tried in Italy by press representatives, including Paul Olsen of Dinside Data in Norway who sent us the raw and JPEG files for the image used here, may or may not have been pre-production samples. Some cameras which were felt to be poor had over 1,000 exposures recorded before the event. Olsen’s camera appears to have been new, recording frame counts in the 40s during his shoot, and may be a final production sample rather than one of the much-used demo bodies.

Adobe has posted updates to Photoshop, Lightroom, and the Photoshop Camera Raw plug-in, both available immediately for download on Adobe.com. The updates provide raw file support for 14 additional camera models and camera backs within Lightroom and Camera Raw, including the Sony Alpha 700. Links here.

IT IS very difficult to find a good JPEG from the Alpha 700 pre-production model tests shot in Italy, because too few cameras were available for too short a time - and many of the journalists present were not photographers. But we have found one image you will love.

THE question is being asked, will the Alpha 700 match the rich colour rendering of the Konica Minolta 7D and 5D? These cameras had identical colour profiles, and were in turn very similar to the Dimage A1 and A2. The Sony Alpha 100 proved very different. Here’s my best attempt to explain why.

System
Camera type: Digital SLR with built-in flash and interchangeable lenses
Lens mount: Sony mount; compatible with Minolta A-type bayonet mount
Lens compatibility: All Sony a lenses and Konica Minolta MAXXUM / DYNAX lenses

THE Konica Minolta Maxxum/Dynax 5D colour modes and conversions are like a whole box of film choices in one roll. This article was written using the 5D in 2005. The modes of the Sony Alpha 100 are similar, but the colour palettes will vary from these results.

I SELL digital images through Alamy, the on-line photo library. When an original piece of art is out of copyright, and displayed in public or by an owner permitting photography, the ability to get a good quality reproduction copy on the spot without lights, tripod or flash is valuable. Some 8 per cent of my overall Alamy images sales over the past four years have been of signs, notices and labels - disproportionately high, compared to the actual number of such shots. As someone has commented, editors like pictures which tell their own story, and sometimes have words in the pictures does just that.

TESTING the flash options most widely sold for the Minolta/Sony unique hot shoe system became a necessity after the launch of the Alpha 100. Despite the reliability of automatic TTL off-the-film flash metering ever since Minolta first introduced it with the Auto Electroflash PX series in 1981, things began to go wrong with the shift to digital SLRs.
