Hi,

I have some problems with studio lighting. I'm using a walimex pro vt-300 with an umbrella reflector. When I shoot 3D objects, I always get this blue-ish background. I have checked the color temperature and it should match with the flash (5600 K +-200 according to the specs), but for some reason I can't get the background white. Even if I try to adjust the white balance (I'm shooting RAW), I can't get it white.

I'm not sure if I just need a second flash to illuminate the background separately. When I tried, I've got it way too bright.

Also the image was rejected by shutterstock because of "Poor or uneven lighting, or shadows". I'm not sure what's the best setup for shooting objects like these. Do I need to avoid all shadows at all cost? I think if the object looks too flat, it's not the best solution either.

Any advice appreciated.

Thanks. I haven't found that droptool you mentioned (I'm using Gimp and Photoshop Elements, so maybe I don't have it).

Seems like I have to buy some more equipment, in order to get decent studio shots.

Thanks for the tips.

YEs, its the thieves that take photos. Thats my whole point Jens. This photo is up for grabs now.

In Gimp (PS is similar) the dropper tool referred to is under the "levels" dialogue. (Colours / Levels from the menu bar) When you open up the dialogue there are three "eyedropper" icons three quarters of the way down on the right. If you hover over them it will say, black point, grey point, or white point depending on which one you are over. Click on the white point dropper then click on the part of the image you want white.

Thanks. I think I've used that before but forgot over time. Unfortunately, it's not making the background completely white. I have found a setting Colors / Auto / White Balance that seems to have the same effect.

Thanks for the trick. I think, it's best to get optimal results in the first place, so I will try to add another flash for the background.

Exactly, you need to get the shot right "in camera" and then make small adjustments to clean up any problems.
I'm not a big fan of "Auto" anything. The thing about the dropper is that it allows you to control what you're actually making white. Anything "auto" is just a best guess by the software.
