Adobe RGB + RAW

[J.A.F. Doorhof]

Couldn't find the info I needed so I decided to ask the experts.

I'm shooting RAW and us C1 for development.
What is wishdom ?

Shoot in Adobe RGB and convert to sRGB in C1 for use on my PC and web.

Or does it not matter because I shoot RAW ?

Also when using Adobe RGB the pictures look slightly duller on my screen when openend with another programm, does anyone know here if the printout on the Canon i950 will be better when used Adobe RGB and printed from PS ?

My idea was :
Shoot in Adobe RGB.
C1 converts to sRGB for normal use.
When I want a super print I will go back to the negative (RAW which I always save) and rework that in Adobe RGB and print.

Does my logic make any sense ?

I don't use C1, so someone else may need to jump in here as far as that goes....

With Canon RAW processed in Canon's FVU you can process into sRGB or AdobeRGB, so your settings when shooting are not a problem, as with other aspects of RAW image capture.

I assume C1 is giving you the same option.

Processing your image into sRGB for web/screen use makes sense.
Processing another version into AdobeRGB when needed makes sense, as long as you don't mind duplicating any work done on the image.
Keeping a RAW version REALLY makes sense!!

Without knowing more about your workflow (like what image editing application you're using), I can't really comment on whether you could have a better workflow by taking a different approach.

Re- the printer, if you're using PS with a properly set up CM workflow (esp. profiled monitor) you should get optimum results by printing an ARGB profiled image from within PS, using PS CM to control the printing. I've had amazing results from Epson's canned profiles, (I know some people haven't), 'fraid I can't comment on your printer.

Hope thats some use anyway.

Ok,

So I will do the following.

Just shoot RAW and don't set the A-RGB there because it doesn't mind, RAW is RAW (I thought that to be true but could not get a definite answer).

For normal viewing I use ACDsee so I will make my JPEG's sRGB.

For printing I will go back to the RAW (alway's do that) and make a TIFF in 16 bits Adobe RGB.

This will be imported in PS and worked on, and printed with:
Adobe RGB, BJC2000 profile.

The most important thing for me is to know if Adobe RGB translates well to the printer, or that the colors will come out dull also because the colors are out of the gamaut.

I could test offcourse, but if anyone has the answer this will save me on expensive paper and inkt.

Frank,

I suggest that you should use a printer profile to get the best results. By all means, convert to Adobe RGB and do all your editing in that space, then just prior ti printing convert/soft proof with the profile for the printer+paper, so you can see whether you want to make any final tweaks. Print using the printer space and make sure colour management is turned off in the printer, so you don't make two conversions, which will screw up the colours.
