Hi,

I need help with setting the white balance and flash exposure settings. My images after downloading are greyed out (Brownish) in the background even on auto.

I have a white background and different coloured objects but almost every image has a brownish backround.

I have tried to set the iso speed at 100 / 200 but images seemed same.

I am shooting indoors with i lg spotlight and 2 small, the camera shows a well lit image after shooting but when i download the image is greyed out.

thanks

Hmm, there might be a number of variables at work here. Perhaps you might like to try some of these ideas and see if anything makes a difference.

First, let's make sure that your viewing apparatus is set up OK. If the image looks good on the LCD, is your monitor brightness set too low? Can you connect the camera to a television and see if the pictures are still brown there?

How much of the white background is in the shot? If there is a lot, then I wonder if the camera meter is being fooled into thinking that the scene is brighter than it really is. The same thing can happen when shooting snow scenes. Try deliberately overexposing to see if it makes any difference.

If the spot has a tungsten bulb then it will cast a yellow glow over the picture. When shooting JPEGs the incandescent setting may help, especially in concert with the overexposure (brown is kind of underexposed yellow, after all).

Have you tried removing the subject of your photos entirely, then using the background to set a custom white balance? Once set you could put the subject back in again and see if the shots improve. If you're shooting in RAW the custom white point can be set in software on your PC (I don't know much about this - it's on my list of things to play with one day).

One other thing occurs to me. If your subject is much closer to the light source than the background, then insufficient light will be reaching the background, and it will underexpose, even if the subject looks good. Try moving the subject closer to the background, or setting up separate illumination for background and subject so that they are both lit to the same intensity.

Let us know if anything works.
