Guest Contributor – TomD – An Alternate Technique for Extended Focus

Here’s another way to extend your focus range without special gear or software: shoot the scene from a distance using a telephoto lens. And then crop in. This works best when using a camera with sufficient MP that you can have a usable resolution after the crop.

This was shot from around 8′ away at around 180 mm.[img][/img]

f5.6 I didn’t want a high (numerical) f stop so that the background would be blurred.

I also have done a lot of macro work, product photography sort of stuff. Depth of field definitely has to be worked around.

Here’s a macro of a fairly high value Mexican proof coin called an Azteca Calandario.

I sold one of my shots to a publisher of Mexican Elementary Math text books. The coin was Numeracion Maya, i.e., Mayan Counting.

These shots were taken with my old A850 using a Minolta 100 mm f2.8 macro lens.
