I just moved from a Sony Ericsson C510 to a HTC Wildfire S.
Although the Wildfire as a flash and teh C510 doesn't, I was able to take pictures in dim rooms better with the C510 than the Wildfire. Even using the flash creates dark pictures.
For example, in this picture you can see in the reflection in the picture glass in the lower left that I used the flash but the flash was so weak that it didn't seem to make the picture any brighter than without the flash.

What settings can I change on my HTC Wildfire S to help make pictures taken in dim rooms brighter?
