Ok, I finally got the Sony a350 and took a couple of pictures. The setting is AUTO, I used a tripod with a remote switch. Two pics, one with black background, the other with white, both in light box using florescent lights on both sides and top. What, if anything, is next?   |

I dunno, looks pretty good doesn't it?!?!?!
I am not sure of the color of the stone, except it is VERY consistent between the two images. Would you say the color is correctly represented?
My gut says it's slightly overexposed, but you tell me.

If it isn't right on, it's VERY close. Looks like I ought to keep the current settings?

Just a thought, but one good test is to shoot a picture of a color wheel&pattern instead of a rock. Then you can see how it is doing across the entire spectrum by comparing it onscreen to what the real wheel is as you hold in your hand. I think you can probably find a color wheel on line to print on a good color printer and then use as the baseline. Hope this helps.

The key words are "good color printer". Mine is old but adequate (funny, that's what my wife says about me!)for my needs. I'll see if I can get a color wheel someplace.

Compared to the black background, the slab on white looks a little washed out, and the background looks pink.
Check and set your white balance (WB) before you click the button.
If you have Photoshop ($$) or Photoshop Elements ($), you can make adjustments quickly.
Turn off all lights in the room that are not being used for your photo. Is your fluorescent bulb a daylight bulb? Daylight bulbs are desirable.
You'll get there!

An open pack of skittles is a good substitute for a color wheel. Everybody knows what they look like. (In the 1980's we used lifesavers!)

The old standard for setting exposure balance was an 18% reflective grey card. Grey background will give you a more neutral exposure.

I bought a set of white balance cards, but I forgot how to use them! I didn't have much luck with them on my cheap camera but it might work on the good one if I could remember how they are supposed to be used.
