This is the original picture
The two boxes show where the image was
cropped. (You can ignore the over exposed sky.)
Here are the images from the bottom
edge and center.
|I would never allow such close
zooming. That is what gigapixel panoramas are for.
This is simply a close up inspection.
The objective is to find the focus
setting that will give you the greatest depth of field.
The next step is to repeat this
test varying only the f stop. You would use the
focus setting here.
Shot with a Nikon D3s and a
Tokina 10-17 set at 15mm shot at f11 (as determined from
the f stop test)
