Figure 1: Cameras that shoot for free software
Posted 06-08-2018
On my videomiscellany.wordpress.com blog, I’d mentioned that I try to find and use cameras that enable the use of free software (as in GPL, etc, and not free as in no cost). I’d started a table to list the cameras that can shoot (stills or movies, but preferably both) in free formats.
Figure 1: A very simple, cheeeep, IR detector for hobby photography
Posted 06-08-2018
A lot of hobby photographers are using IR cameras, or retrofitting common cameras to do IR photography. If the camera is a retrofit, then the photo hobbyist may not know the level of IR before a shot is taken.
This easy junk box build is a way to discover at least a ball-park guestimate of how much IR is present before a shot is taken.
The nice thing about this detector is that it uses a photodiode that reaches all the way down to 1.7 um (micro-meters) in the Near IR / Mid IR boundary area. Some newer cameras may be able to take photographs in that band.
