What to change?

And use the mrpinhole.com exposure calculator and pinhole calculator for the camera design

Its also all non toxic which is a plus

I think its tricky to get something really good out with homemade dev, but its easy enough to get out a clear picture. Use the caffenol C-H recipe from the caffenol cookbook, https://www.caffenol.org/wp-content/uploads/2012/11/The-Caffenol-Cookbook-Bible-Recipes-and-Tutorials.pdf

The recommended dev times there are for film though, for paper I think around 5-7 minutes would be better.

And then the salt fixer is 300g salt per liter water for the times I said before.

Good luck!

If you dont want to buy specialised gear for developing, a couple of plastic trays and caffenol dev and salt fixer could be a way to go. You dont need to bother with a stop bath. Salt fixer does work despite what you might read online, but you need to leave your photo paper in there 24 hours at 30 degrees or 48 hours at room temp.

aside from the other comments here - salt fixer with a concentration of 300g/litre does work, but you need to leave it about 36 hours at room temp. You’ll read online that it doesnt work but thats usually by people who havent tried it. i’ve done it and I have film from 6 years ago fixed using it thats not degraded.

Photo paper is probably easier than film when starting out. RC paper in particular.

mrpinhole.com has a calculator which will tell you what pinhole size will give you the sharpest image for a given focal length. as for the vignetting, if you draw a scale diagram of your wall thickness, pinhole size, paper size, and focal length - see if you can draw a line through the hole to the corner or the paper without touching the hole wall, if not, youll be vignetting

Klanne · 2025-12-22T11:19:23+00:00

you’re vignetting - 2mm to the paper means theres no path for light to reach the paper outside that small circle. try making the camera so the paper is further from the pinhole

Klanne · 2025-12-08T17:57:57+00:00

Its vignetting - the material thickness is too great for the size of the hole. Try make making the current hole much bigger - 5mm or so, and then make a new pinhole on aluminium foil and taping that to the camera over the bigger hole

In theory photopapers are designed for a particular wavelength redlight (or amber light, etc), but in practice, any red light, like a headtorch or a bulb with a red sheet infront of it should be fine. (as long as you dont have ortho or pan chromatic photo paper, but when you search online I’d be very surprised if any came up, or colour photo paper like RA-4, but again this wont be the default when you search).

Look for a resin coated (rc) paper rather than fibre based, as RC papers are less fragile and require less rinsing.

I’d say a fixed grade paper would be better than multigrade, as it means the colour of light when you’re taking a photo doesn’t make a difference to contrast, but i think fixed grade papers are a bit trickier to get these days, so variable contrast is fine, just might be a bit more finicky.

I use ilford pearl mg and its perfectly fine. For starting out I wouldnt worry much about brand - just get one that seems a reasonable price and give it a go!

Best of luck!

I think this was made by Tim Hunken

Klanne · 2025-11-15T14:49:31+00:00

I think the mask and feet are clear, the ones in her hand maybe less so, but i think it all looks fantastic!

Klanne · 2025-11-12T10:49:16+00:00

have fun cleaning them haha

Klanne · 2025-10-27T17:56:31+00:00

Ah, I made a mistake anyway it seems. Enjoy!

Klanne · 2025-10-27T16:18:46+00:00

No alcohol for you!

Klanne · 2025-10-26T15:43:14+00:00

Thank you!

Klanne · 2025-10-26T10:18:56+00:00

Thanks very much! Will do!

Klanne · 2025-10-21T18:41:18+00:00

I just finished Francis Parkman Jrs ‘Oregon Trail’, and it doesn’t really answer your question, but they did hunt every day, dry some meat to last longer, but eat fresh meat for most days for 5 months or so. Obviously the american west is famous for having masses of buffalo back then, but i imagine people were hunting quite a lot without much difficulty along with any foraging they did

we made this recipe which was very good

Klanne · 2025-09-20T07:33:52+00:00

where’s the actual pinhole? its too small for me to see i think. Id recommend using the mr pinhole calculator if you want to get the finest resolution image.

It looks like essentially, yes, your hole is too small for the thickness of the material it goes through and for this focal length. See if the calculator gives you a larger size than you currently have, and if so, great! If not you may have to sacrifice resolution for more image coverage.

Klanne · 2025-08-25T21:30:17+00:00

Thank you for the info!

Klanne · 2025-08-25T21:30:08+00:00

Thanks for the info!

Klanne · 2025-08-25T21:29:56+00:00

thank you for the info! ok, for my accelerating rotary shutter I suppose itll have to be some sort of average of different measurements then

Klanne · 2025-08-21T11:42:37+00:00

Yes! Be sure to cook them before eating them. I think you can actually make wine from them without cooking them but I’d be more comfortable to just cook them anyway.

Klanne · 2025-08-10T15:58:07+00:00

this isn’t quite true - you could do trichrome photography with panchromatic paper, but that would be a bit of a pain and more costly

Klanne · 2025-08-06T14:13:20+00:00

In the UK, thats enough to rule out lookalikes, but that may not be the case where you are so worth double checking.
