Quote - Mark, what you posted is a JPG, there is no way we can analyze what the problem is in the PNG file if you convert iot to JPEG. Please post the original, untouched file. There is no reason for a color shift when saving the image from Studio.
If the image is too large use YouSendIt, it's free, just use the Lite version http://www.yousendit.com/cms/liteaccount

I uploaded that as I couldn't get my png image to fit within the upload requirements. I will upload it to my soon to be non-existant website and post a URL. The only difference between the two images. One has transparency the other has a black background and thus show's the pink that exists in both images better. From most of the tutorial's I've ever read they usually postwork the hair after the render. Even in poser I had to render antialiasing off. The only way I could render for animations and eliminate the color bleed issues.

Cabbieg: Yes, I've used background's successfully in studio. But I have never been able to successfully use a background with a ground plane successfully in the new studio as your background cover's the entire back wall of the scene. Not from the ground plane up. Thus you must zoom out so far to get it to line up with the ground scene that you would end up rendering ants in the distance as it were. If you decide to move your scene forward after that, the camera changes with the scene putting you right back at the start. In one of the older images of studio I managed to use backgrounds with a ground plane successfully. When done right it look's great and save's alot of unneccesary work. And my render's almost alway's include a background as a backdrop for the main scene as I like to do garden or fantasy forest type images.

Mark.

p.s. I will get the original png URL posted later.
