On-Set DOS Utilities
These are a series of utilities which provide a wide range of computational solutions for film, video, and still photography shoots. They come together as a suite of tools, and provide most of the computational power needed for a smooth pre-production experience.
Computes sunrise, sunset, twilight, distances, and sun positions for approximately 250 cities. A limited number of cities can be added, and the program generates printable tables of rise times and positions. Determine which days of the year the sun will appear in a certain position. Print out tables ahead of time to bring along on your scout. Conversion calculator allows you to do your angle math on a map, on location with a ruler and a string - or by measuring a shadow.
Running Time Calculator
Computes elapsed time for any format, length of film and frame rate -- or vice versa.
Computes exposure based on film stock, over/under exposure, frame rate, variable shutter angle, etc. Computations are performed bas either on footcandle readings or as conversions from meter f/stop readings.
Everything you need to know about image size, formats, depth of field, diopters, and appropriate focal lengths. You can even convert lenses from one format to another based on height, width, or frame diagonal; and easily compute positioning for split diopter shots.
The program to use if you haven't yet discovered M3S. Keeps separate inventories of 1000', 400' and 100' rolls for up to 5 film stocks. Full printouts of current and previous usage, as well as average and projected usage calculations. Generates a list of short ends on hand. Computations are limited to about 500 rolls of film.
The programs were originally written a while ago and run under DOS, which means that they run best if you exit from Windows and run in exclusive DOS mode... which of course you will probably never want to do. So the next best thing is to run in a full screen DOS window -- you just have to watch out for your screen saver and mouse settings.
