actinglightIt's a time for new update. We've made several pictures to illustrate how many light our flash can give at various conditions. Because ActingLite allows to set up pulse length by menu, we've made several shots with different pulse duration to illustrate how light amount depends on it. To do it we've placed a paper scale on the wall and make several shots changing the pulse duration. On the scale each big line means 5 cm. For all shots we've choosed the following camera settings: ISO 400, shutter 5.6. We've used ISO 400 instead of 100 for two reasons. First, choosen camera settings covers all exposure range of the set, making comparison of pictures simple and clear. The second reason - ISO 400 currently could be considered as a maximal "working" ISO on all modern DSLR cameras, giving images with no detectable quality reduction. Pulse length indicated on top-right of each shot. It is possible to see - not all LED placements in our prototype are ballanced well. Also lighting angle is too wide. We're working on it. According to out calculations the final head design will be up to 50% brighter.

Strobe mode
The second useful approach is to use strobe mode for flashes supporting it. Fortunately ActingLight not only supports this mode, but even allows to setup pulse length and interval between pulses. For each shot we've used pulse length 1/500000 of second and interval between pulses 1/5000 of second. Some samples:

Single pulse, trigger to pulse delay
This update will discover some tricks of capturing the picture of flying bullet with ActingLight. All pictures placed here were made in our lab during testing.
As you know the most tricky thing in capturing the flying bullet or other things going very quickly is to catch the right moment to make a shot. Nobody can react well enough, to press the camera button at right moment. So, the most common approach here is to place camera into the dark room, use long exposure and any kind of trigger detecting the flying bullet and giving a signaling the flash to make a pulse. Does it work? Yes! But where are still some trics here. Let's calculate a bit. The bullet doesn't fly with the speed of mind, and even with the speed of light. It flies much slower. The typical value for air gun is 100 meters (10000 cm) per second. So, if the gun is located at 10 cm distance from the target, it will take 1/1000 of second for bullet to travel this distance. Because the simplest place for trigger is the gun itself, flash shouldn't make a pulse exactly at the moment the bullet is detected. Some delay is necessary to let the bullet to travel to the right place. To illustrate this we've prepared a paper scale where small line indicates each cm and with larger lines each 5 cm and make some shots. Fortunately ActingLight has the unique feature - menu-driven delay setup. So, we've used 1/1000, 2/1000, 3/1000, 4/1000 of second delays. Gun was located near 7 cm right to the scale. Let's see some results:

Dear friends, probably you're were intrigued how ActingLite looks like. We are sharing here some pictures of it's prototype used to take all pictures here. Although design is not final and we're going to make the case smaller, current pictures can give some idea how ActingLight will look like.
