[QUOTE="-jeffB, post: 2046576, member: 27832"]Your camera tries to adjust the overall image so that it's not to bright, not too dark. Since your background is pure white, it dims the whole image, making the coin very dark. This will happen whether you're using a flash or not. If you use a black background instead of white, the coin will be brighter, possibly too bright. You'd get the best results by using a grey backdrop that's about the same "brightness" as the coin itself. The pinkish background tone comes because the camera is trying to set the white balance based on what it sees. If it sees a mostly-neutral-white background with a greenish coin, it'll shift everything a bit toward pink in an effort to compensate. If your camera has a setting for "exposure compensation", you can set that higher to brighten the image. Most cameras have this setting, but it may be hard to find and use. I think even my cheap cell phone has it, but it's enough of a nuisance there that I rarely bother with it. When I'm shooting with my DSLR, I use it frequently. Many cameras also let you set a custom white balance by shooting a gray or white object under the same lighting conditions before you take your actual photo.
