Question on hyper focal distance focusing when nothing in frame to focus on?
Ziggy wrote: So what do you do when you can't focus on a point because there is nothing in frame to focus on? I understand you are going 1/3 into the frame, but if you have no reference point, then what?
Then it doesn't matter.......
Why so serious?
Sure, practice makes perfect but, unless you learn from your mistakes, you are only perfecting your ability to fail.
For macros, as Matthew said, about halfway in between, and use a much smaller aperture..
Clear as mud, right?
