TPB #48 – Flash Duration Verification

Posted by:

This video goes over the Flash Test Menu and finds why it hasn’t been reporting correct flash durations. The problem turned out to be the light sensor being used is not fast enough. To make this mode work reliably we’ll need a new light sensor that quickly transitions from <1V to >4V. I estimate a responce time of less then 5 us would be good for standard flashes and less than 0.1 ...

TPB #32 – Camera Axe Helps Crowdsource Bullet Time Effects

This week I am sharing some work from Guy Viner where he brings together a group of photographers to create a bullet time effect. The brilliance in this idea is you don’t need to buy a bunch of cameras since all your friends are bringing their cameras. This video goes through how he setup his shots. He was using the Camera Axe to help time his flashes.

Thanks to Guy Viner for ...

TPB #24 – Faster Analog Reads on the Camera Axe

Posted by:

This week I describe how the Camera Axe will be using a faster analog read mechanism in future releases. This new method sacrifices some precision for 8 times faster read. After including the overhead in the Camera Axe software the overall improvement is about 2.5x. This puts analog read performance much closer to digital read performance.

A huge thanks to gvi70000 on the Camera Axe forums who suggested this change.

You can get beta ...

You can get the new beta Camera Axe software with these changes here.
