Why are my indoor pictures so yellow?
Why are my indoor pictures so yellow?

I'm using an Olympus D-520Z. The first one is with a slow sync flash / shutter speed. The second one is better, but still yellow. It was taken with the auto flash. Both had WB on auto.

Thanks in advance, Brad

first shot taken w/strobe. looks to be incorrect white balance. check your white balance setting.

second shot w/strobe much closer to natual color in strobe localized area. of course after that its going to go to the yellow because the strobe won't go out that far.

It's because you've got mixed tungsten and near daylight strobe light. Push up the shutter speed to kill the tungsten, so your strobe will be the only light source for the shot. Don't rely on Auto white bal to get mixed light right. Better to kill one or the other, then use auto or preset. I now use about 1/200 for indoor flash shots. (Have you got manual settings?)

In your second shot you would have got better foreground balance, but the background would be much darker. You will now see why larger external flash units are recommended by most digicam owners. If you must use internal, get closer. In this shot you have the tungsten light source from the ceiling in shot, and you could have moved forward a bit. The auto white bal. sensor will have 'homed in' on the ceiling lights!

Why use slow sync flash? As far as I remember that just makes things worse! You allow more tungsten light to get through, before the flash fires.

Actually Vox is right, play around with the shutter speed. People actually do use theses settings to good effect (ie warmer tone) rather than just the cold harsh light from the flash only.

What you'll get is a right balanced picture, with everything in the background blacked out with a more powerful strobe output, but is that what you want?

Yes, I just remembered - I think the slow flash sync is to shoot night shots so the shutter opens, exposes for the dark background, then the flash fires just before the shutter closes to expose the foreground.

I take your point about deliberately mixing light sources, but the results are often unpredicatable, whereas re-balancing in post is like fine tuning. Although you may know the light sources are different, the camera is much more adept at showing it unevenly as shadows and casts in places you hadn't noticed. That's more difficult to sort out with the eyedropper!

My camera (Olympus D-520Z) doesn't have manual shutter speed. I do have control over the white balance.

I used slow sync because I thougt with it's slower shutter speed, it would be better. I guess it's only for outdoor night shots.

Thanks for all the help.

No choice then but to get closer, or experiment by blocking the exposure sensor if it's external.

I now realize that the zoom should only be used outdoors. And that I need to be no more than 10 feet from my subject, if I'm using the flash.

thanks for all your help
