And another thing: Hyperfocal Distance
Same thing, really: make sure stuff is in focus. This time, it’s landscapes.
The 28 September photo of the day shows the problem: is the stuff in the foreground really as sharp as it could be?
After that trip, I looked up the whole hyperfocal distance business. Here’s the approximate formula: square of the focal length, divided by the product of the aperture value and the circle of confusion:
$latex H\approx\frac{f^2}{Nc}$
For our camera, that’s focal length squared, divided by f-number times 0.020. The answer comes out in millimeters.
I applied this (roughly) for the Falcondale Lake pictures. I think they look a bit sharper…
