| p.1 #4 · Lightroom export sRGB vs ProPhoto RGB (JPG) |
I have been trying to get a grip on jpg export from Lightroom and I'm not sure how to address the issue. I understand a bit about color spaces. I shoot in RAW, Adobe RGB, import into Lightroom as ProPhoto RGB, do my edits, and export for web display as sRGB jpeg for compatibility.
When shooting raw the only thing influenced by the camera's color space setting is the preview shown on the back of the camera. Unfortunately we are given the option to choose between sRGB and Adobe RGB but that choice only affects the preview and JPEG shooters. Also, its impossible to import a raw file with ProPhoto RGB color space. Lightroom's internal color space is a hybrid called Melissa RGB and it cannot be changed by the user.
The choice of color space is only relevant when the raw data is rendered i.e. converted to a pixel-based file format like TIFF, JPEG or PSD by exporting the file from Lightroom or sending it to Photoshop or other external editors for futher editing.
I use ProPhoto to provide the largest color gamut for editing however it's not ideal when displaying jpegs on the web. The problem I'm having is that I get color shifts in my images and it is very noticeable on skin tones, they become more red. I have tried opening the NEF in Photoshop and using 'save for web' but that didn't help. I have also tried to soft proof in Lightroom, select sRGB profile, create a proof and export that proof to jpeg. Same problem.
Once again, you cannot edit files in ProPhoto RGB in Lightroom; the only working space is Melissa RGB. Is your monitor profiled and calibrated? Have you checked to see if the profile in use by your operating system is corrupt? Lightroom is particularly sensitive to corrupt profiles.
Is there a way to avoid this? Should I just import images as sRGB? Ideally I can maintain ProPhoto RGB for the bigger color gamut in case I need to print or for future work. What is the best workflow to display images on the web and maintain the colors?
Note, using a color aware browser like Firefox is not the answer, I can't enforce what people use to view the images.
Thanks for the help.
