This is actually a very good lesson. I'm glad someone came along to point this out.

Working in jpg, even on our Challenges which are downloaded as JPG files, is not a good idea. JPG is a lossy format, so every time you save it recalculates how much information it can throw away, and you never get that back.

So first thing to do is 'save as...' a PSD or TIF file. Then do your work, and absolute last thing export a JPG version only for submission, not for storage or printing or anything else.

Also Mr. Nelson. What I like to add to this is. That's why some color geeks on jpg's(and the web as well for displaying pictures). Doing all the color correction to an image. To getting an image to perfection on screen, and to format the image to jpeg. Is a..............waste.? You don't have to have it perfect, per say. The blue channel gets hit the hardest. The rest of the image as well as the blue channel also depends on the rate of compression on how it gets wacked. Having ImageReady is good to have, to see what's happening to that. And then adjusting for that. Then you have the browsers' issue,...ect..ect.. on the web, on how its displayed. With all this like in that old movie where Al Capone, wacks those guys on Feb.14. The St. Valentines Day Massacre.
