I have recently bought the canon camera, PowerShot G9. But I have to say, I am not completely satisfied. I took some pictures, and the resolution was not so special. It had nothing which could say, ”yeah this is 12.1 megapixel”. I am sort of little disappointed. But is there something which needs to be adjusted in the camera? And there are not even so many shoot modes to choose between. Either you have flash, or you switch of the flash. So could anybody help please. I bought this because I read so many good reviews, and now I am just a little sad, because it was expensive 
I guess an easy thing to check is the file size of the picture you took. My Canon 8 megapixel camera uses about 3.5 MB for most pictures. And I have it set for the highest resolution. If your file sizes are less than that, then you need to check you camera settings.
Turn your camera on as if you are going to take a picture. Select "Func" and use the navigator to get to the resolution (should look like a quarter circle). Make sure that is set to the highest, "Superfine". Then go down to the size selection and again select the highest, "Large".
Now take a couple of practice shots and see how they look on your computer.
For your different modes, you have to be in Manual mode. The Auto mode limits your selection.
I would recommend taking a photography class at your local community college. They will show you the basic for any type of photography, but also help you understand your camera.

I took some pics with my G9 at ” SCN ” mode ” landscape” feature, some picture reads at more than 6 MB most 6.5 MB.
Many features in the SCN ( indoor, outdoor,pets,nighshoot, lendscape, color accent, color swap,etc and etc , about 13 features in it ).
keep on ”scn ” mode press and slide your finger on the round thing that is called control dial where the ” Fun/ set " at the center, so you migh see the modes above appear and run on screen.
Should go to the ”menu” select on ” tools” down to ” reset all ”
then reset your camera once.
Hope this help.
