A reflex pinhole camera for 2025

Mods I have started a new page I hope this is okay
Making another camera project for 25
My 40 + year old model Thanes Sailing Barge that was under going a renovation once all ship shape a pinhole camera would be fitted .
I'm thinking could be great for pinhole day 25
Round and round in circles I go....
I had been running tests using an Arduino Aducam the problem was fitting a pinhole on a very small sensor.
So I arrive back at 'Old School' analog photography.
The design of the camera will be a challenge because of the amount of space under the deck of the barge.
Who said it will be easy.
I have an idea a mirror or prism could be the answer.
Back in time, two or three years ago I had an exhibition of my homemade cameras , I was still working on a pinhole camera for the exhibition that reflected an image on a small drum, it didn't make the cut and ended up in my ' will finish one day' box of odds 'n ends.
So let the testing start again.
The results had some promise I reckon I could be on a winner.
Then dought set in, the 40 year old sails could get damaged , maybe best if I don't use the barge.
And as for a reflex pinhole camera well that could be a winner
Plan 'B'
A 120 wide view camera it will be reflex ( just for the challenge) taking 6 x12 sized image.

Working on the film deck
I found a roll of Siberian film squirreled away

Paint the film deck and start on the top

You bet! Thanks for sharing your project! Looking forward to see how it pans out.

Add a dab of paint and it's looking very smart
I thought why do a film test.
The film was very old so I rated it about 50 asa and processed in coffee.
Well the negs where so dense , dip 'em a farmers reducer should help
I must order a few rolls of fresh film and developer.
The new Foma it any good?
Okay the question could I be happy... what do you think Col.

Overall, yes. I've shot tons of Fomapan 100, quite a bit of 200 and 400 as well. The 200 has issues in 120 format, so that remains a gamble, but the issues may not be bothersome on a lo-fi pinhole image (it'll be far better from a technical viewpoint than what you got with the expired film, that's for sure). The 100 and 400 are just fine anyway.

My only complaint about Foma 100 and 400 for pinhole is their rather poor reciprocity characteristics. Whatever your meter comes out to, in seconds, raise that value to the 2.8 power (easy with a calculator app on a smart phone).

are you sure, Don? That would turn 10s into 10.5min!

Hmmm. You may be right, that seems like more compensation than I've given in the past. I'd have to go look up the Ilford reciprocity method and the factor I worked out for Foma 100 and 400. It may have been 2.8x for each stop past one second, rather than power of 2.8...
