Speed Test Gallery

These tests were done by filming a gun-fire with a camera set to take 50 images/sec (interlacing 25 frames/sec). The white background with the black stripes are used for reference-lines. By measuring the distance a projectile travels between two frames we can calculate the speed. The lines are 10 cm apart. We have "stacked" images from consecutive frames into the same image to ease the measurement and to show how the projectiles travel.

X m /(1/50) s = X m * 50 = Y m/s
