Photoclub Alpha

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.

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 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.

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!
