But first some specifically stereo thing. Stereo viewfinders. In the olden days, when I had a couple of Nikon Fs and twin Nikkor 24mm wide angles, I arranged them vertical, eyepiece to eyepiece at eye separation distance (65mm for me) -- and walked around using it as a high quality optical TTL stereo hyperstereo world viewer -- and I was very pleased with the wide angle hyperstereo effect.
And more recently I have done the same thing with digital SLRs and twin Nikkor fisheyes for VR180 stereo snapshot photography.
Lucky for me the minimal eyepiece distance is 65mm -- and I love using it for stereo snapshots -- but the lens interaxial is large (140mm) so not good for close subjects -- though the new PTGui (v.12.0) is great for handling alignment with hyperstereo pairs.
I prefer mostly to use a base to base vertical-oriented DSLR rig for stereo snapshots -- with a more generally usable lens interaxial of 85mm -- but then I can't have this TTL stereo viewfinder thing happening. But then I noticed I had managed to collect a couple of Lomography fisheye viewfinders ... the one here:
These are pretty mediocre viewfinders, but they have an accessory shoe. And I had a couple of accessory mount tripod adapters so it was easy to make a very portable stereo fisheye viewfinder rig with them mounted side by side on a small piece of aluminium bar.(You need to swivel the mounts inwards a bit til they align when you are looking through them.) In stereo btw the view is much sharper looking than when looked through singly -- yet another proof that eye and brain are a synergistic system stereo-wise! This is really good compact rig for previewing scenes in very wide angle stereo.
I have done more experiments - with holding one fisheye viewer adjacent to the eyepiece of one of my fisheye DSLRs (vertical) -- and that surprisingly works too for giving a good stereo view -- the coverage is not the same, but the visual scale is the same(accidentally) -- and despite the drastic difference in clarity the stereo summation effect much reduces the expected blur (if you are looking though the DSLR with your dominant eye.)

Black Ink paint app:I bought this recently on Steam when it was heavily discounted. I am really interested in nodal paint apps and there aren't many -- and I think it can be very good for depth map retouching
