A Tutorial on Hyperfocus Technique 4 Months, 1 Week ago Karma: 0  
This thread discusses the Content article: A Tutorial on Hyperfocus Technique

First off I think you mean refraction rather than diffusion.

This assumes you want infinity to be in focus. You may not. say you just want everything between 2 - 5 metres in focus at f8. Then put the 5 m mark on the right hand f8 mark. This way you achieve zone focus.

No, not refraction...maybe "diffraction" ?

I think the effect is called "diffusion"...shine a flashlight through a hole in a piece of cardboard and the beam of light diffuses. Diffraction is the spreading of light outward due to distance.

I know hyperfocus is a type of scale-focusing. The article was addressing it specifically and not scale focusing in general.

Okay, it's "diffraction". I'm going to correct the article now.
