Colour mismanagement can cause absolute havoc when doing camera comparisons too: Especially newer cameras that are released and Adobe get caught with their pants down without a reliable profile for* this can really make a mess of things especially when it comes to seeing the differences between two different sensor architectures - this can have a severe impact on initial findings when comparisons are made.
Originally posted by Rondec The difference is tiny and as Ian mentions, is probably mostly due to the Raw Converter used more than anything else.
Quite right, At the time In the studio I would have to light models with significantly softer light with the K10D. When I bought the K7 I could afford to use slightly harder lighting, and when the K5IIs came along, it brought dynamic range that could handle it if I needed to give the shadows/darker mid-tones a lift without introducing significant amounts of noise like it would on the K10D/K7. This trait follows with the 645D and 645Z**, my lighting choices have changed somewhat. The need to quad diffuse my softlights has been reduced as the dynamic range of the 645Z gives
tremendous flexibility in how tonal ranges can be manipulated. Though I do prefer the subtle nature of the 645D's CCD rendering, Whether it is an artifact of the RAW engine or a complexity derived from the spectral bandpass of the CFA layer used with the CCD...it takes a practiced eye to spot it at times, but there is a subtle
depth to colours on CCD cameras. Many of my clients have well developed colour perception so this makes the qualities of the straight out of camera output from whichever camera i'm using of considerable importance, first impressions count for a lot.
* Fortunately for me, I am capable of developing my own highly precise camera profiles.
** This change was also mirrored with the Leica S2 which made a similar change from CCD to CMOS.
