How Can I Help This Photo

That's a little more like it.

Color can be re-found. You should have a Custom white balance function that'll fix it for you.

ok lets try this

lol thanks dave! I actually had the wrong reverse in the last picture so I just updated it. I know your not going to like this but I am using a flash light until I can get to the store and get the proper lighting

Whatever works for you, buddy. It's about results, not methods.

Love the look of that coin.

Something I note worth mentioning, which your lens suffers from: See the greenish hue around the rim of the coin, and where the shadow meets the paper? That's called axial chromatic aberration, and is likely something you're not going to be able to correct. It happens when a lens is not able to focus every single light wavelength at the same distance relative to the sensor. Zooms tend to suffer more from this than fixed lenses, and your SX30's huge zoom involves more optical compromises than most.

The color shift is most noticeable at areas of high contrast, like where the copper color or dark shadow meet the brighter white background. Your only hope of minimizing it is to drastically reduce the contrast, which is probably an unacceptable compromise in the quality of the image since we really don't want the coin blending into the background.

Not likely. Won't change the fact that every color of light is of a different wavelength, and lenses can't always focus all wavelengths at the same spot. More light will probably make the problem worse.

I only brought your attention to it because as you get better at this (which you're doing pretty quickly), it's inevitable that you'll notice it. Others reading this thread will as well.

for what it is worth..while we put all the light on the coin we can, the coin does not respond well...many times it depends on the coin....silver or copper...many times it depends on weather you zoom in at full levels or back off some levels. and the camera you have has its own ideas...when you have manual or "P" progam funtions you have the most control of what the camera could do as Dave and Ray shown...While I used to shoot at full blown every thing I found I get better pic's with my point and shoot camera..by backing off of the full potential of what the camera thinks it can do...FOR COINS not for other shootings..
after the shot... there can be adjustments to quality of the picture.. thanks Ray..

I am not sure what you mean. The first coin is a 1928-s the last one I posted is a 1923-s
