DOF Charts for Chips

[John O'Brien]

I know the ASC Bible has DOF and Field of View charts for film, but is there a publication with that info for chips?

There are plenty of 2/3 inch chips out there, but the newer chips are bigger sizes, can this be calculated without the camera? Has anyone done the math?

The search function here has tons of info on it and it's easy to use.

Camera dojo has a nice post on this here : http://cameradojo.com/2008/09/09/how-to-calculate-depth-of-field/

You need to know the Circle Of Confusion (COC) which can be rather complicated but a pretty good calculation for a CCD or CMOS is roughly the sum of the diameter of 2 pixels.

David Eubank (a fine AC) has a great application called pCam http://www.davideubank.com/ which is an excellent way to manage this data and calculations.

Hope this helps

I'm familiar with the search engine. It is nice. I couldn't find any "DOF Chart", "Chip Chart", etc.

Thanks for the helpful reply Michael.

I've read many discussions about DOF, I actually read this thread, I was just asking if there was a chart the Red community is aware of, possibly a pdf., that charts the distance near/far compared to f-stop for various sized lenses and for various sized sensors.

David Eubank's application looks promising; I just don't own a Palm or iPhone.

I would suggest the American Cinematographer's Society Manual
