After sleeping on it, I think a lot of my problems with Wacky Camera are internal reflections

It is made of aluminum sheet metal, painted black long ago

I am going to buy Scope Flocking to put inside http://www.scopestuff.com/ss_flok.htm

I also will try different Zone Plates and Pinholes

Why would internal reflections only be in a single direction?

Is the direction the line marks are the same as the movement of the darkslide? I mean could it be you have leakage when pulling the darkslide. That each line is the edge of the darkslide.

The bottom inside surface is really shiny...

I never completely removed the DS as 3" of the DS slot side of film is never exposed and both sheets processed totally clear in that area.

So I think the light traps are sealing the DS, and IDK...

I like the Spampod.

I don't eat Spam, but will when the time comes

However I just installed 3/8" floor flange and a bit of pipe for third leg

Waiting on 0.8mm pinhole to test again

Mr Pinhole told me so

I built this 8x10 in a day:

The idea is to photograph trees from ground level, setting them against the sky, with a dramatic perspective, but without converging verticals:
