I have a relatively cheap camera, a Canon A80. Before I started reading up on things I was pretty happy with it. I think the increase in knowledge has actually temporarily hurt me :) At any rate, I'd love to take some long exposure shots of some of the local waterfalls. Unfortunately, I think I may be "stuck" and wanted to ask if anyone knew what I was doing wrong. From my reading I understand that the "higher" the fstop, the smaller the aperture (the less light), and combined with the shutter speed this determines exposure. COnsequently, if you leave the shutter open longer, I'm understanding that you have to compensate with a higher fstop. The Canon A80's highest fstop is 8. The picture I recently posted (my second entry for the challenge) was taken where there was a quite a bit of natural light. I had my fstop at 8 and I really wanted a longer exposure. But anything over 1/20 for shutter speed made the entire picture horribly over exposed. So now that I've rambled, my question is... Am I stuck with not being able to take these kinds of shots because the A80 only goes up to 8 for the fstop? Or am I completely missing something crucial here? Any suggestions would be greatly appreciated. Thanks!
