Just got hold of a digital camera and I got to say the picture taken in my house are underexposed(don't know what it actually means, but I mean they are dark portions in the Pics). So suggest me a software to correct them. I tried picassa but as I increased brightness the photo lost its quality. I am not to much aware of hue,saturation,gamma etc. So please suggest me a no fuss software. My camera doesn't have much settings not much control on white balance. The ISO settings are customizable, any idea as to what ISO settings to keep for dim lit areas. Waitng for your reply.
