You'll be very surprised how well natural convection air flows work,

Inhabitants of hot arid regions (Arabia, North Africa, the Gobi) have been using convection and wind-induced circulation for cooling for literally millennia. The key to all of it is that whatever draws air out of the house draws it in through an underground passage -- even in in the Sahara, a couple feet below grade stays very close to annual average temp, which has historically been much cooler than daytime.

Make one or two Venturi 'windows' for box fans, out of PVC pipes, wall board and pipe line reducers that are 50% smaller at the exit port than the fan breeze inlets.

It might take a small bit of effort but even with the fan(s) on low, the air forced through the window will be at least ten degrees Fahrenheit (10°f) lower, which should help you to remain somewhat cooler in your work space.

Furthermore, to draw the heat up and out of the attic, you can also make a attic solar chimney by way of metal or plywood construction of an attic mounted, non fire, chimney and a hose or pipe that can bring up cool airs from your lowest room or basement, into the attic proper and let the heat rise up through the chimney, by convection.

Many years ago, I owned a {moderator's deletion of politically inflammatory label} house, that was fairly large, but had been designed with natural convections that would keep it cool and breezy on the hottest day in the southern most N.C. & S.C. border county.

You'll be very surprised how well natural convection air flows work, and, with the Venturi but x fans, it should really help out on the hot attic days.

Cheers

It's a clothes closet in the attic. If was a permanent space I'd have an AC installed. As it is I can't even stand up in there, I use the space to cut and load film. It's the only film safe space I have. In the past I have installed a window unit in the room and let it run for a bit before going into the darkroom. I got a few minutes of comfortable temps out of it before I had to take a break.

My 127 cameras:
Primo Jr - Probably the best of the bunch
Baby Rolleiflex - Very close second to the Primo Jr
Kodak Vest Pocket Autographic - Amazing how compact these are
Kodak Vest Pocket Autographic Special
Kodak Vest Pocket Autographic Model B
Kodak Brownie Reflex - My mothers old camera
Kodak Brownie Starmite
Zeiss Ikon Baby Ikonta 520/18 - Broken, never was able to get the shutter working

Here's some examples:

Thanks for the photo shares. I was just thinking it would be nice to own a baby TLR, then I saw a mention somewhere that the Primo TLRs were made by Tokyo Kogaku (Topcon), and I thought, they must be good then. Your photo shows off the good glass and precision.

The key to all of it is that whatever draws air out of the house draws it in through an underground passage -- even in in the Sahara, a couple feet below grade stays very close to annual average temp, which has historically been much cooler than daytime.

When I converted a passenger van to a camper van I cut a hole in the floor and installed a floor register (screened outside to keep insects out), and at the opposite end in the roof I installed two roof vents. With the windows covered on a hot day the interior of the van stays almost at ambient temperature purely from convection. Also helps that the roof is painted white and much of it is shaded by solar panels and racks. In the summer while using the van I duct the air from the floor register through an evaporative cooler. The solar panels easily power the evaporative cooler. In the winter the floor register is used as the air intake for the wood burning stove (small Newport solid fuel heater, designed for sailing yachts).

For the last few days of my 127 month, I tried the Bell & Howell Infallible Electric Eye 127 camera. Haha, grand name isn't it.

And a few photos with expired ReraPan 400 and orange filter.

That is small, and I was thinking a eight by eight or ten by ten foot space, at the minimum.

Good luck

3x8ish but it's a sloping ceiling from the roof. I have just enough room to fit a small table and chair in there sitting. Like I said, gets the job done but I have to be careful not to smash the back of my head on the clothes pole behind me.

For those who are interested, Rerapan 400 is now back in stock at BH Photo and Freestyle (maybe other places) but the 100 speed is still back ordered.

I grabbed a few rolls of the 400 as it tends to disappear quickly...

Thinking about doing an astrum/svena group buy, and they advertise 46mm film. Not sure if there’s an MOQ, maybe, maybe not. Anyone here interested? I’ll even roll it for you if you give me spools and paper!

Something slower than HP5+ would be great! I like that Ilford supplies it in 46mm annually, but it's not my ideal film for a pre-war baby rolleiflex.
