Depth of Field Calculator

Many people have requested a simple means of calculating the depth of field and/or the hyperfocal distance of a lens. In the course of my wanderings, I have found a Windows depth of field calculator that I believe is up to the task. You can find it here:

The download link is about mid-page.

Enjoy!

Got to play with it, but it looks interesting. Thanks for link!

Curtis N, of POTN fame , also has an Excel Spreadsheet based one that some might want to take a look at.

Anyone using an iPod Touch or iPhone, I purchased the app called "PhotoCalc". Awesome tool. You can calculate flash exposure, general exposure reciprocation , and DOF. It also contains a glossary and other great features like sunrise and sunset times VIA GPS, and info on filters and such.

DoFMaster is one of several on-line calculators, some good, some bad.

I should have said "a downloadable DoF calculator." An on-line calculator does you no good out in the field where your laptop has no uplink.

And no one thought of looking through the viewfinder, pressing the DOF button while turning the Aperture wheel? Tisk-tisk...

Try it, you can see the DOF change before your eye, and as we all should know, a picture is worth more than just words and numbers on a chart.

I have news for you. We don't all shoot F1.2 lenses, we don't all have the eyes of a sixteen year old, and we don't all shoot on brilliant sunny days. I almost NEVER use the DOF field button for the more serious side of these reasons. With the tiny viewfinder on my Xt, it's about useless, and my new 40D isn't much better.

I've found a couple (Google) the work on an old Palm I found at a garage sale, but they are a PITA to tailer to 1.6 crop, being designed for 35mm

I am 62, I would have to sell two body parts to afford any lens capable of f/1.2 and I live in an area that get's more cloudy days than London. And even I can see the DOF change when twiddling the Aperture wheel. Have you actually tried it yourself?

And while photographers are farting around with palm pilots and laptops, the opportunity has gone South with the Greater Purple Goose.

I notice on the Depth of Field screen that there is no entry for the circle of confusion value that is part of all such calculations that I have seen in the past. Do you have to set your camera type elsewhere in the software or does it just assume some default/average value for the COC?

It's there, just gotta scroll down. Hyperfocal and COC are down there. In the options menu you choose camera type, and it's the most comprehensive list I've ever seen.

Of COURSE "I've actually tried it myself" that's why I made the comments, the point being that it's not very useful in a great many situations. Because the viewfinders on my cameras are so dismal, what you "see" through it really doesn't mean much.
