Advice- Cant figure out m

Question:

Photography Question - How do I shoot in Manual ? Tips/Advice- Cant figure out my Digital Camera?

I have an Olympus SP510
and I have been shooting on Program
I cant figure out how to use Manual Setting
No matter how much I change the settings - like
the ISO and white balance - nothing seems to help
Photos Outdoors are TOO Bright & over exposed
Photos Indoors are TOO DARK - even blacked out !
I cant find where to adjust the Aperture
Help any suggestions / Tips ???

Best Answer - Chosen by Asker: i'm not familiar with your camera but mine have something like a meter that shows me if the picture is going to be over exposed or underexposed... it looks a bit like a bar code without the numbers and if the setting is correct, it would only show one bar... it is on the bottom of the screen... hope this help
