Filmmaker Daniel Scott Murphy has created an incredibly useful new crop factor calculator that goes beyond anything we've seen online thus far. Not only does it tell you the crop, it actually simulates the results, and can even handle setups that include speed boosters.
You can't avoid crop factor these days. Whether your camera sports an APS-C, Micro Four Thirds, 1-inch, or some other size sensor, there will come a time when you'll have to calculate a "full-frame equivalent" and that's when the mmCalc Crop Factor Calculator will come in very handy.
ISS Transit Finder is a new web app that's designed to help astrophotographers figure out when and where the International Space Station will fly across the face of the Sun from a vantage point on the ground.
A couple of months ago, we featured a helpful little web app called the Bokeh Simulator and Depth of Field Calculator. The website allows photographers to quickly visualize what different options in a particular shot (e.g. aperture, focal length, distance to subject) do to the bokeh and depth of field in the resulting photo.
The app has now gotten even better: in addition to some nifty feature upgrades, it can now be downloaded as a free app for Android devices.
Christopher Mitchell recently breathed some photographic life into a pice of technology many of us probably have languishing away in some drawer. With the help of an Arduino board, he’s found a way to Frankenstein a Texas Instruments graphing calculator and Game Boy Camera into the ArTICam: a 128–128 grayscale selfie machine.
When it comes to understanding how depth of field, focal length and other variables are affected by different film/sensor formats, it can get confusing. Fortunately, Reddit user redblue has created an incredibly useful interactive resource that will help you better visualize the factors at play by letting you change variables while swapping sensors sizes and seeing the effect in real time.
If you've taken almost any math classes over the last decade, chances are good you have a graphing calculator sitting around in some drawer somewhere. And while we can't promise you'll ever use what you learned in Calculus (an engineer friend of mine used to call it 'calcuseless') the folks over at JACP Media can help put that old calculator to use by turning it into a homebrew intervalometer.
Kaufmann’s Posographe is an intricate pocket-sized mechanical calculator invented back in the 1920s. Measuring 13x8cm and filled with tiny scribblings, the device allowed photographers to approximate the exposure values they needed by simply sliding around six small pointers.

The golden hour in photography is the first or last hour of sunlight in a day that photographers often aim to shoot in, since the sun's position produces a soft and warm light with longer shadows. The Golden Hour Calculator is a useful website that can help you calculate the golden hour(s) for your location, telling you exactly when the sun rises and sets.
