To my surprise, I'm finding that iPhoto's editing tools do quite well for Basic Editing challenges.

However, it's like a desaturation/reduced contrast effect takes place when I export a RAW file to JPG, then upload. I'm looking at two windows next to each other: the JPG opened in Preview and the exact same file uploaded to DPC. And the DPC version isn't as saturated.

How can the same computer show the same image file in two different ways?

I've turned off colorsync profiles in iPhoto, but it still happens.

Anyone got any suggestions?

Thanks!

iPhoto is probably exporting that JPEG in a color space other than sRGB. Preview can handle it, but most browsers "assume" sRGB and show you what the image looks like without conversion (lousy).

Yeah, that's what I figured, but the iPhoto help seemed to say that by turning colorsnync off, it defaulted to sRGB.

Got any idea how to fix it?

Oh, and a test shows that Safari seems to know how to display it properly.

Thanks, Apple, for forcing an unwanted "improvement" on us.

That's what they're good for.

Safari is the only major browser that supports color profiles, so that pretty much proves the theory. Try this.

FWIW, firefox 3 has supported color profiles for over a year now. The described problem certainly sounds like an non-sRGB issue (it always is when people complain about this).

I found out Firefox 3 doesn't support profiles by default. You have to turn it on. I did, and it made a difference.

But the annoying thing is still not being able to use iPhoto to spit out sRGB. I have to do it manually in the colorsync utility.

I also figured out that my PC laptop's blue display brightness was too high. So at least I've got my Mac laptop and my PC laptop roughly agreeing with each other now.
