dang stuff...

I recently got the book Digital Wed. Photo. by Glen Johnson (great book, thoroughly recomend) and he pointed out something that I hadn't realised but made a few things clearer. Colour Space, Adobe RGB is better but printers ALL print using sRGB meaning that you loose some of the reds causing people to look grey (now I know why that was happening!!)

I just got a bunch of prints (the first set since I calibrated my monitor) and was expecting them to be identical to the on screne images (how idilic my mind is :D !!!) only to find that the skin tones were all greyish :(

So... to avoid this we must convert to sRGB ourselves or leave it to the lab to do so (assuming they know what they're up to :rolleyes: ) the Q I have is at what stage is it best to convert to sRGB? in camera raw (I use Photoshop)? In photoshop itself or somewhere else??

Also how do I go about changing the colour space? I can't seem to find an option in PS. There's one in camera raw (in the workflow options, sRGB IEC61966-1).

One last thing, if we have to convert to sRGB before printing why bother with Adobe RGB in the first place??

so in summary:

no.1 What stage is best to convert to sRGB?
no.2 How do I convert it?
no.3 Why bother with Adobe RGB?

Cheers, Davy

PS: I've just realised one of two things either there's not hash key on my mac keyboard or I'm going selectivly blind!!

Looking forward to hearing from you guys.

1. Convert just before saving for the final time.
2. Edit > Convert to Profile (towards the bottom).
3. Why do you shoot RAW if you end up with JPEG?;) To use every piece of inforamtion you have until you just absolutely have to change it. Same thing applies here. Also, your screen doesn't display the total gamut either.

Take a look at the book Real Word Color Management by Bruce Fraser for ALL the info.

Well, I understood it that 8 ink or more ink jet printers could use the aRGB space gamut.

I have repeatedly asked Question #3, after asking (and getting few replies) about commercial printers who can print aRGB files. The wisdom seems to be 'So you have it when you finally can use it.'

I'm not guru on this but I think that there are printers out there that will recognise that your pic is in aRGB and convert it to sRGB properly for you automatically.

I'm not sayin that 8 inks don't use aRGB though.

Thanks, I see what you mean when you compare it o RAW

one last thing (then I promise I'll leave this alone)

In the convert to profile options box I have Engine: Adobe (ACE) or Apple CMM

and Intent: Perseptual or Saturation or relative or absolute colormetric.

and use black point compensation
and use Dither.

Please advise

Thank you so much, Davy

Getting into those options you really need to read the color management book - book thread link in my sig. Leave it alone until you understand it, then you'll likely leave them alone anyway.

Each print firm accepts different things. I have two labs I regularly use, one accepts any color space and prints in that space. The other accepts aRgb or sRgb but converts to sRgb for prints. Other less professional labs don't know what a color space is.

Thanks Tim,

I'm just trying to get this batch finished off ASAP, I have the book on order.

That is what I thaught about my pixma 9000. When I print using aRGB the prints are very over saturated. I havn't looked into this at all yet though.

I send my prints out to Adorama's printing service and I convert to their color space before sending. They have them for download. That way I get accurate colors from their particular printer. I always use aRGB before that. Straight out of the camera gives you the most to work with.

I believe you are confusing color space with ICC profiles. ICC profiles can be dowloaded but not color spaces.
