Online Depth of Field Calculator

Online Depth of Field Calculator. Ok, if you end up spending more than a hour playing around with this thing, you can classify yourself as something of a nut. If you grab the code and try to improve it, you’re nuttier still. Right now I’m having an “Almond Joy” moment ;)

Seriously, this is a fun tool. Did you know that, if you used a 50mm lens @ f1.4 on a D20 focused on a subject 4 feet away, that the depth of field would be scant 1.21 in. ? Well now you do. A very cool feature of this calculator is that it includes predefined data for many popular digital cameras (such as sensor size and actual lens focal lengths) that factor into DOF calculations. Heck, it even had info for my old Canon A20.

The website for Keith Schengili-Roberts’ book, Core CSS, has a very nice CSS property compatibility chart.

Not only does the chart show browser compatibility for each browser, but is also provides the syntax and a sample for each property. A quite bookmarkable page.
