Why the color change
Can anyone tell me why photo of a purple flower shows blue when I upload to BP? It looks so different on my Mac. I have a calibrated monitor and when I opened the image in PS I converted the SRGB to Adobe RGB 1998. I saved the image to 72 dpi and made it 720 on the long side. Help!!

It might help to know what photo you're talking about. Also, if you could compare how the photo looks when uploaded to other web sites and when viewed in other programs like Preview, or how various photos look in Photoshop and in other web sites, that may also help narrow down the color-changing culprit.

Thanks,
I did upload it to another site and it looks blue too. I have other flowers that are purple and uploaded right so I can't figure it out. Here is the photo

Why did you convert to Adobe RGB 1998? sRGB is the recomended std for computer display. These profiles define diff color spaces, so colors in one may not exist in the other... and therefore have to be mapped to a different color. This may be what is happening... e.g. that purple shade may not exist in 1998, so it is mapped to the blue color you see. Also, did you attach an ICC profile to the image (using PS "Save for Web", check "Attach ICC")? Another thing to try... what does the image look like when you open the file from your PC using IE and/or other image display software? I always check my results with Cannon ZoomBrowser and sometimes IE or Windows Picture & Fax Viewer. (Note, if you use File Explorer to browse to your image file and right-click, select "Open With..." you'll see a list of installed programs that can display or edit the image. Some may use an attached ICC profile, some may ignore it.) I haven't experienced any color shift problems using sRGB & attach ICC. But can't say if any of my pics happened to have the exact same shade of purple in them. dvc

Thanks for responding. I have to search and figure out what ICC profile is. I'm very limited in PS. I took a course and I think when I set up my PS the instructor told us to use Adobe RGB 1998 because it has more colors. Now I'm going to check back. Maybe he meant it for printing.

RE: ICC The key thing is simply to make sure the 'attach ICC profile' checkbox is selected in "Save for Web" ... this attaches information needed to properly intrepret colors in the image so they are displayed correctly (or as close to correctly as possible) on the output device. You can experiment with sRGB vs 1998 to see if it makes a significant diff but I think attaching the profile will probably solve the problem without doing anything more. More info on color here:

Oh, I should also note that I also (often) edit with the 1998 profile, but I always convert to sRGB prior to Save for Web.
