Hey All,

Are there any good Depth of Field Charts or Calculators for 16mm/Super16mm? I've found some online, but I was wondering what you guys use to calculate DoF for 16mm/Super16. Thanks!

I use the look up charts in the American Cinematographer's Manual.

The panavision website is good. I don't know if you already have it or not but here it is.

I use pCam but you do need a Palm Pilot. You can find it on David Eubank's website www.davideubank.com

I have a 16mil kelly wheel. It calculates based on a CoC meant for projection, I think, so it usually underestimates my DoF. I think that's a good thing in most situations.

I just got a copy of the American Cinematographer's Manual. In looking at the depth of field chart, I have a few questions:

1. How does the Circle of Confusion correlate to DoF? Is CoC related to film size (16mm, 35mm)? Or is it independent of it?

2. How accurate are the charts in the ACM? I used dofmaster.com's online calculator and got totally different measurements. I tried changing the CoC to .00125mm, but still the numbers were different. I also looked two columns left of the current fStop as per the manual's instructions.

3. In all honesty, what is the best way to calculate DoF if you want the smallest CoC and want to make sure that you subject is in acceptable focus for Super16mm?

Thanks in advance. I'd like to know how you guys calculate DoF.
