A few pics I took tonight
I see all your pics turn out just like mine. yellow. I called the factory and they said tough. if you ever figure it out, let me know! I'm tired of having to color correct every photo in photoshop.

Thanks, I get yellow even when I take a photo in a light tent, or in the sun. I think maybe that $250 camera is a lemon. That, or the technology is just beyond me. Maybe I should change my ID to Old F*rt. <grin>

Maybe I should change my ID to Old F*rt. <grin> Did a manual come with that camera? If so go to the part that discusses setting white balance, especially custom white balance, and do what it says. People seem to have a lot of trouble with that for some reason, but if you set it correctly your images will no longer be yellow no matter what kind of lighting you use. To make the procedure better, go to a photo store and get an inexpensive 18% gray card. Use it to calibrate your white balance before every photo session and voila! No more yellow backgrounds. I can't remember whose image of Ethiopian opal this is (nice one!) but it looks much better with its original white background instead of yellow:

Yep. It is the 'White Balance' setting in your camera. Look for the 'White Balance' adjustment by hitting 'Menu'. You can try auto white balance (AWB) and your camera may be able to adjust it automatically. For your situation you probably need 'Incandescent' or 'Tungsten Filiament' or the image of a light bulb. Here is some typical 'White Balance' menus

Maybe this tutorial will help those unfamiliar with white balance settings. My camera allows white balance "bracketing," and I keep that as the default. It means I get 3 versions of every exposure: one that conforms to the white balance I set; one that's slightly bluer and one that's slightly redder. If my original WB setting wasn't correct, usually one of the others is. It's a nice feature if your camera offers it but it does involve deleting a lot of extra images -- no big deal IMO. www.digitalcameraworld.com/2013/09/12/white-balance-photoshop-fixes-and-in-camera-solutions-for-any-situation/

Yeah, I read that part 3 times, and set everything to the settings it said. Still came out yellow. I'm thinking maybe I need to take it to a camera shop and ask for help! Finally figured out the macro and autofocus stuff, kinda sorta, it takes nice crisp 14meg pics, but gotta get that yellow under control. some examples...

I don't know what to tell you about that problem. I exported a couple of your images above to Photoshop and hit "auto levels." Both seemed to revert to a white-balanced color - very nice, no yellow that seems unnatural to my eye. Of course I haven't seen the originals. I still suspect a problem with your WB.

My camera gives the above , but what I use is a different setting. The WB goes from -2 To +2 in increments of a third. You can see in the camera screen which setting is true to actual color. Select the one wanted, then click.

I take terrible gem and mineral pics, too, @tumbleon. Opals are the worst and I don't think they like to have their photos taken. Photos I take outdoors usually turn out much better than the ones in artificial lighting.
What plans do you have for the welo? Nice slabs, and what are they?

Read more: forum.rocktumblinghobby.com/thread/65083/photos#ixzz2xXqGrnqSPhil, I get lazy and take pictures under my desk lamp. It is '50 watt Natural Light flood' by Phillips. I do not have a camera in the house that will adjust the yellow out using white balance settings from that bulb. Try another bulb, try natural light. If you still have yellow in natural light with a white balance setting set for 'sunlight' or 'shady' then your camera must have issues. The white balance simply paints the photo a different tone to make up for light sources that have different tones. Cloudy conditions should be colder(bluer). Try shooting in overcast. If it is still yellow then your camera is really off. But the wrong white balance setting will paint most any conditions yellow.

Here is my set up. Two 1940's desk lamps, one with 100W coolwhite other is PlanetLight 60W incandescent. Against the white paper seems to give me best focus and white/color. Some rocks need a darker background, but most do best for me with this set up.

Phil, these are your images after I imported them to Photoshop and adjusted the levels using "Auto Level." The process used only information that was already in your original images: I haven't added or subtracted anything. These seem to me much closer to the actual colors but you'll be the judge. My point is that your camera is recording the actual color of your subjects but some camera setting may be causing the yellowing.
