Hello, been trying to learn and resolve some problems that I've been having with colour spaces used in my workflow. I think that I've got the answer, but I want to run it past the people here to see if I've got it right.
Starting with the problem, well actually lets start with the set up.
I shoot in RAW, camera (40D) set to embed RGB as the profile.
I import into Lightroom 2.1 and do some basic tweaks.
I import into CS4 and process the image further.
I save the image back into Lightroom as a TIFF.
I export the image as a Jpeg for web, printing, and RM stock.
So the what was the problem?
When I viewed the images processed in CS4 and saved as a TIFF the colours were way out in Lightroom, especially skin tones which were overly pinky/yellow. But when I then exported those as JPEG using lightroom the colours were a closer match to what I was seeing on CS4.
What I think I was doing wrong was as follows:
RAW (RGB - OK) -> Lighroom (ProPhoto RGB -OK) -> CS4 (AdobeRGB - BAD!) -> Lightroom (ProPhoto RGB - displayed AdobeRGB tagged TIFFs funny) - JPEG (sRGB - which threw away the colours anyway so looked OK)
I've changed the colour space for CS4 to ProPhotoRGB and now the TIFFs are a much closer match from what I see in CS4 to what I see in Lightroom.
But this leaves me with a couple of questions,
What happens at the end of the process when I dump them down into sRGB colour space, how do I control the colours to make sure that they will look ok converting from ProPhoto RGB to sRGB or is this not an issue?
Should I be going through all my old TIFFs and updating their embedded colour space to match the ProPhoto RGB used in lightroom, which is my main library app?
Any comments or advice on what is the best practice would be good. I'm new to this but doing my best to learn as I go.
Thanks
Andy
