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.

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.

FUJIFILM UK Ltd. (Managing Director Hiroshi Saigusa) has announced that it is to increase prices on its range of photographic papers and films in the United Kingdom. The price changes are being implemented on a worldwide basis.

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.

Sony Corporation today announced the development of a 35mm full size (diagonal:43.3mm) 24.81 effective megapixel, ultra-high speed high image quality CMOS image sensor designed to meet the increasing requirement for rapid image capture and advanced picture quality within digital SLR cameras.

In mid 2007, rumours of a 14.8 megapixel Sony sensor came from the usual Far Eastern ‘inside’ sources. As a full-frame Alpha model (the so-called 900) had been previewed at PMA 2007, it was possible this megapixel count related to full frame, or near-full frame. It now looks as if it may have been a leak of development for currently rumoured 14.2 megapixel (active) Alpha 350, which is an APS-C sensor camera.

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.

THE PRESS and trade announcement made below on August 20th 2007 does little to confirm on deny rumours about the forthcoming AA and Flagship DSLRs. Why? You need to study the image, and study the dimension data, and fully understand what they are talking about, before the implications are clear.

IN 1998 Minolta published, for their 70th anniversary, a large poster featuring all the landmark cameras from their own museum and employee collections. Many of the cameras shown – all fairly small on the poster – were well used and worn examples. The original image-files for the poster, which we have archived, are of poor quality. They are Japanese inkset CMYK sharpened for pre-press, with very dark gamma. This page re-creates all the information from the original poster, complete with the photographs. This page has been updated so that each period now appears as a separate section – simply select the next page to move on after reading each one. Page 1 is 1928-39, Page 2 1940-1959, Page 3 1960-69, Page 4 1970-79, Page 5 1980-89, and Page 6 is the 1990s. If you know the period of the camera you want to see, go straight to the page.

It was equipped with a rollfilm back as well as plate holders. The flash synchronisation worked, and the 105mm f/4.5 Anastigmat lens was sufficiently good to permit one commercial studio shot to be completed using the camera, though contrast and light transmission were both low. The camera has a folding sports finder (the wire frame) as well as an optical coupled rangefinder and an optical viewfinder. It was a copy of the German Plaubel Makina.

DxO OPTICS PRO 4.1 is the latest version of a clever raw file processor which includes lens lookup tables to auto-correct distortion, vignetting and chromatic aberration. It also lets you alter the look of Dynax or Alpha images so they match popular films – or other DSLRs by Canon and Nikon!
