Subject: JPEG comperssion and color loss

I'm having problems maintaining the original colors of an image after I compress it into JPEG. Is there a better way of of doing this rather than manipulating the original to adjust for the JPEG? I'm currently doing it by trial and error.

Maybe you could try PNG and see how the colors hold up in that.

I just tried a couple there is less color loss in the png file but it is to large to use on the web

Color change? That's not usually a sign of JPEG compression. How are you saving the images? It kind of sounds like a colorspace issue. I had the same problem when I first started using AdobeRGB as my colorspace. Was saving as JPEG and there was a serious shift in colors. I found I had to convert my colorspace to sRGB first to get a good approximation. The biggest problem is that if you save for web, you will never get the exact colors because web browsers don't color manage. -=>Donald

That may be my issue I have been saving for web. I'll give that a try. Thanks

Randy - Just remember, if you are sending the jpeg up onto the web, using Save for Web is the way to go. If you just save it as a normal Jpeg under SAVE AS then you also get a bunch of stuff appended to the image in the header that can effect some people using certain browsers (the image will either not display or in some cases can lock up their browser). -=>Donald
