I've been wanting to ask this question for ages, but haven't gotten around to it until now. I mainly take landscape photos some which include people in it every now and then.
However when I take the picture, I can never seem to get the entire frame in focus (with detail). I have a basic understanding of and you can control this by adjusting the (f/value), and focusing to infinity (sideways 8).
When ever I take pictures, it seems that the majority of the frame in in focus (around 90%) and the remaining (usually around the edges) seems to be out of focus (not in detail). Also, what mode should I use (or is that for auto focus only)?
I'll post up a few pictures later tonight and show you what I've done in the past. Could you show me of point me in the right direction on how I can have the entire frame in focus?
