Don’t Be a Dabbler

I have a hobby of printing images onto cards and making "constellations" of the cards.

A bit more than six months my ago son introduced me to

and between time spent doing other things and figuring things out and eventually getting a good stereo camera it took about six months before I started routinely making good stereograms. Or I made a few before I ran into a really baffling problem: I made a tkinter application that let me process a stereo image and I found the 3d effect would often look great in tkinter but not look quite right in Photoshop or when I printed it.

Turned out there was a problem with color management which I was able to prove by making an image that looks like a TV test pattern and taking a screenshot of the image in tkinter and in photoshop where the colors aren't the same.

In some sense I felt this was a setback and a real pain in the ass but in the long term I'm going to perfect the art of stereograms and this is what it takes.
