The camera is metering off general background, which it tries to make 
a neutral grey ( refered to as a 17% grey). There are several 
solutions, the white background can work in some situations. 
1) Find out from your manuel how to change the metering to center 
weighted metering. This will let it set exposure according to what is 
in the center of the lens. 
2) Set exposure using a neutral colour. This can be done by pointing 
the camera at a neutral grey card, back of your hand (works for me), 
a cut out picture, or other neutral shaded object at the same 
distance from the lens. Wth most cameras if you half push the shutter 
the camera will lock in the exposure, then you point the camera back 
at your subject and "click"
3) A lot of cameras have an exposure adjustment. Check your manuel 
and then set the exposure for about -1 setting. This will make your 
photo darker , but the flower will be correctly exposed. It may need 
more or less then -1, you'll have to experiment.
4) White balance is a setting available on some digital cameras. Try 
your menu button and see if anything seem similar. 


Check camera manuel for further help. There are a lot of adjustments 
that can be made. I just about have all the buttons and adjustments 
figured out for my camera.
