This is probably a “duh” fact for many of you, but one that some of you have perhaps never heard or realized before: Did you know that the flashes in the Canon Speedlite lineup are named after their maximum guide numbers? To figure out the power of your Speedlite, just take the model name and hack off the zero at the end to get the GN (e.g. 430EX has GN 43, 580EX has GN 58).
Here’s a “duh” idea that might not have crossed your mind: you can use your iPad as a portable light table by displaying a blank page on the browser. Might be useful for those of you who are thinking of doing some printing in your bathroom or something.
Of course, you can use a cellphone too for things like 35mm negatives, but an iPad is much more similar to a portable light table. This idea is courtesy of photographer Dalton Rooney, whose free WordPress theme for photogs we featured a while back.
