I am about 75% finished with my article comparing RAW converters for Nikon F-mount cameras. I tested ACR, Nikon Capture, Capture One DSLR Pro, and Fuji EX 2.0
Really, this could be quite interesting. Which cameras did you test? I have a feeling you will see differences among converters when used with the D70 and D100, despite the cameras' similarities.
On the Wetpixel trip, I was agog by the beauty of Capture One that Eric and Alex were using with their respective Canons, although one particular sun shot of Eric's showed a huge variation (C1 was not so good in this case). I compared this with the washed out look that Nikon View had (which was the case on Paul Ng's Apple notebook as well as mine). I hadn't seen much difference between my limited trial use of Nikon Capture and CS, so I've been using CS for easier workflow. I haven't found a single review of C1 and the D100. I recall an unflattering review, but I may have confused it with the Silverfast Raw converter.
After seeing C1 and the Canon cameras, I've been less impressed with CS.
