Good App

This is a one of the best apps I've found for figuring general reciprocity failure for most films. While I have only used it with a couple of films, I have found it to be accurate. This app would be great if it had a timer built in. Right now I have to exit the program, start a clock/timer program for timing the exposure. It would be great to have a timer that would automatically enter the shutter time then when the start button is hit it would count down from between 5 to 10 seconds. Then make a warning sound to start the exposure, then make another warning 5 to 10 seconds before the the end of the exposure. There is room at the bottom for the timer. Thanks!

I love cinematography, I hate math

It's always nice to have calculators like this on set. Without it, I'd imagine making a huge fool out of myself doing the math in head or by hand.. Greatly appreciated!
