Keith and Josh, I apologize for accidentally stumbling across a very old post and posting on it - and I note you closed it immediately after posting your comments, so I couldn't respond to your comments. And I apologize that I "cross posted" to that one, thinking I could consolidate our two very similar posts. I didn't know it was not allowed to share something from one post to another - since I thought my experience might be helpful to that thread.
I am new.
Josh, to respond to your comments, I THOUGHT I had the manual, but on looking closely it was called "Canon Powershot G10 Photography" and it did NOT have the diagrams in it you described - and that I'd been looking for. I downloaded a user manual from the internet but it is too small to read, but at least I'm on the right track.
I read your comment "
The "Av" button says "Av" right above it and has a "+/-" icon as well" (hopefully that isn't considered "cross posting" - I've had to change the thread back to my original post since that one was closed) On my camera, there is not an "Av" button. It is a dial I turn to go from Tv to Av to M. There is a +/-0 icon in the upper left hand corner of the monitor when I'm in Av or Tv mode but not M. But I don't know how to change it if that is what you are referring to.
When I am in Av mode I can turn the bottom dial of the settings next to the monitor, and it then changes the Av settings. Likewise, when I am in Tv mode, that same dial will adjust the shutter speed. However when I'm in M, I can not figure out how to vary the aperture settings. Right now that dial will only change the shutter speed, not the aperture settings. And I can not, after reading, looking on line, etc., figure out how to set the
aperture.
I purposely wrote Canon G10 hoping that someone familiar with my camera might know the answer. Meanwhile I will continue to look for a user manual that I can read.
Again, I am very sorry I made the errors above that I did. I continue to learn.....
