Hey guys I have a basic digital camera

Canon SD790 IS ELPH 10.0 Megapixels

anyway I have always loved photography but know little about it, I know what the manual says with the camera but is there a link on here that explains what combos works best for certain situations, like ISO numbers exposure etc........

I was messing around and I found some awesome options like taking pics and everything is black and white exceot for like a red sign, stuff like that, it was awesome anyway is there a guide on here or can anyone provide me a link on where I can learn to maximize this lil cameras potential

Thanks
guys

Also I am an airline pilot so I am always seeing beautiful sunsets etc but the pics always come out like garbage so I would really like to learn some techniques
