Hello,

What would be the advantages and disadvantages in Capture One 4.1 of outputting TIFF 16 bit files for local adjustment in CS3 with the following:
1) Camera embedded profile (Pentax K10D and K20D in my case) no conversion to workspace profile in CS3
versus
2) Adobe RGB
3) Prophoto RGB
The final output will be:
sRGB JPEg for web
TIFF to canon printer profile for 8*10 prints

Thank you for your input.

Cheers,

The fewer color space conversions the better. Starting with the larger gamut working space from the converter OR the native color space if that's even happening, the better. I don't know enough about C1 under the hood to say if #1 or #3 is better (#2 brings nothing to the party) since I don't know what underlying processing color space is used. I'd assume its the so called camera profile but don't know for sure.

Yes from what I gathered in the Phase One forum, it is a camera color space with a 1.8 gamma. I assume it is somewhat smaller than Propohto RGB?
I know that there has been long (heated) exchanges in this forum regarding color spaces that passed way over my head
Assuming the following:
1) camera color space with 1.8 gamma attached to TIFF
2) stay as is in CS3 during local adj
3) color space conversion at time of output (proof and color gamut tools)
- sRGB (close to 2.2 gamma) for web
- canon iP6700 custom profile (is that in gamma 2.2?)
Does it make sense to use gamma 2.2 in CS3 and for monitor calibration (I use sRGB) as it is closer to output or should it be better to use gamma 1.8?

Thank you very much.

Cheers,

Luc.

Without plotting the gamut maps in 3D one could only guess.
