- Joe tries a novel process of in-camera Lumen prints, pre-wetted to accelerate the auto development of a visible latent image.

A very interesting experiment and as usual a great video:) Looks like you've produced a modern day Calotype that I'm sure Fox Talbot would have loved to have used. On a side note Fox Talbot also incorporated a 'developer' in his paper negatives much later on in the process to enhance the sensitivity of the paper. Just goes to show 'what goes around, comes around'! Looking forward to future 'developments' (groan:). Cheers!
since I started playing with this I've shot (besides the camera from joterman himself) mostly with brownie box cameras. I find they lend themselves really well to the process.
you’ve used this same technique in a Brownie?
@@daniellemartel7454 yes, why do you ask?
William Mortensen used to make interpositives with developer soaked paper. He would then retouch these, contact print a negative, then retouch that, and finally print the final image. The interpositive was suppose to be very low contrast for retouching. Mortensen passed in the early 60s and didn't have access to developer paper. Looks like another thing to add to my list of things I have to try. Contact printed a lumen years ago but got so-so results. Maybe my binocular lens large format box camera (thanks for that one) could be pressed into use.....
I will try a comparison of dry and wet. It's been suggested that any paper will increase in speed if wet. So far have only done cyanolumens, ie coating the paper with cyanotype chemistry, which of course also means it's wet. But I doubt that there are any developing agents in RC paper, something I've never heard of or experienced.
hah! I hadn't seen this video before. that's my post on the filmwasters forum at 0:25 :D
How about making a clear acrylic tank to seal up the paper and solution?
I've been toying with ideas to keep a wet plate negative 'wet' for about an hour with the same idea.
What lens would you recommend getting for this particular size DIY camera? I’ve been a bit lost and have no idea what type of lens I would need. I absolutely love the way the wet paper reacts, the final images look dream like and the soda ash is a great idea!! I’m excited to make one!!
A single lens with the correct focal length to project an image onto the rear of the box. I like to visit stores with magnifying glasses and test them out to see what the focal length is. Another idea is find a lens and build the box to match the focal length, that might be easier!
@@Joe_VanCleave thank you so much for your reply! Unfortunately I don’t have any old lenses but was going to purchase one. Would a biconvex lens with a 50mm focal length work for a small camera? I was going to build around the lens.
misting the inside of a camera sounds like a really bad idea. try squeegeeing your wet paper onto a sheet of thin clear plastic to block evaporation, or maybe add a humectant like glycerin to the water.
Good idea about the plastic sheet, and glycerin. As for misting, experiments I've done show it leave an inconsistent film of moisture, making the image mottled.
You are going to be reinventing Polaroid paper again?
