Gorge falls, Michigan
Camera turned vertically
Multiscope made 2 versions of their Baby Al-Vista. The first version had a tension knob to control speed settings similar to the 4A and 4G cameras, and the second version, had fans like most of the rest of the line.
I just started shooting with a #2 baby al vista. and developed a bunch of negs but haven't printed anything yet. More to come on the baby al vista.

In order to use it I needed to measure the various parts of the camera and lense so I could get the right exposures, as none of this information was available.

I've been using charts from larger al vistas to determine a starting point for exposure with some success, but need to do some testing. Here's the exposure chart I'm using to start.
#1 three second fan 1/8
#2 six second fan 1/4
#3 eight second fan 1/3
#4 ten second fan 5/12
#5 twelve second fan 1/2
