Adorama Photography TV presents: How to calculate hyperfocal distance for maximum depth of field.
Sometimes when shooting, you want everything sharp from the front to the back of the scene. Setting a small aperture can help but if you really want to maximize depth of field, hyperfocal focusing is the technique you need to use. And in this episode Mark will explain how to calculate the hyperfocal distance.

A really good explanation from Marc as usual but I have to suggestions. First you mentioned " set the aperture to 8 or 16 or lower". That confuses since the aperture value and the aperture size are inverted to each other. What should you set lower is the question that popped into my head, the aperture value or the aperture size?
Secondly I would have like to see an practical test showing the difference in real life also.
Apart from that it was really great.

While the explanation was reasonably clear, it assumed a lot about the background of the photographer. Unlike the inverse square video where there was ample demonstration, this video was more technical than I wanted to grapple with. I'll stick with autofocus and smaller apertures for more DOF.

Thank you Mark and Adorama.

Using the same standards of judgment that are used for a 35mm sensor, we'd need to divide 0.03 (the circle of confusion for 35mm film) by the crop factor for the digital format we are using to get the CoC value for that format. So, for example, the Nikon D2x which has a 1.5x crop factor, we'd need to use a circle of confusion value of 0.02 (that is, 0.03 divided by 1.5).

Mark this was great, although I have a questions. I have one of those lenses with the DOF scale and I am using it with a 1.5 crop sensor. Do I need to consider the circle of confusions? and if the answer is yes, how? Thank you.
