Topic: Shooting without developing or Have you heard of Lumenbox?

[jojonas~]

I stumbled upon Lumenbox on instagram a while ago and while I've seen paper exposed in ordinary cameras and solargraphy pinhole cameras I hadn't quite seen anything like this before.

two points interest me mainly:
1. he loads the camera outdoors
2. he wets the paper before loading to make it more sensitive

you can see both done here in this youtube vid:

and a peek on the instructions he sends with the cameras he's seling:

here's a good example of done negatives:

and to be fair, a link to his etsy where he sells these:

a friend just got a bunch of darkroom papers where one box came without the black bag so I'm having him send that to me for testing something like this

Having a bad day today. My brain stopped working at dawn this morning. But for the life of me, I can't work out how this works.
Anyone?

Lumen printing is nothing new. It is usually done in a contact printing frame with either a negative or objects (for a photogram). The paper produces a latent image without development. The image can be fixed, but it isn't necessary. You can scan it immediately and toss the original. This version is just done with a little meniscus lens camera instead of a printing frame.

Tarja Trygg gives an interesting description of the process in this document:
http://www.eso.org/sci/publications/messenger/archive/no.141-sep10/messenger-no141-43-45.pdf

The colours in black and white photo­ graphic paper exposed to light come from finely divided metallic silver growing on the silver halide grains. The latent image, which is typically ~ 10 silver atoms per billion-­atom grain is invisible, but on con­tinued exposure the latent image clumps grow so that the  first visible signs of a print­out image are yellowish, darkening to sepia then a maroonish-­brown as the particle size increases. Eventually the maximum exposure produces a slate­ grey shade. Reversing an image with this natural range of variations will produce interesting colours, which are of course unrelated to the real colour of the scene. However, lightly exposed parts will be bluish and shades of green/cyan will likely appear in the mid­tones, both of which will lend the positive images a natural look.



...oh, and here's some flowers if anyone read that before their first coffee in the morning

it was the last time they saw each other by jonas lundström, on Flickr

I got this from flickr considering the wetting of the paper:
Maybe wetting modern RC paper can help activating the embedded developing agents so sensitivity increases? /gruss.mir

I did a bit of a facepalm after reading that!  how many times haven't I checked papers for incorporated developer before lith printing?

talking about fixing, does anything happen with the final image when fixing it? I thought that I had heard about loss of tones

[Francois]

I can't really tell if there is a loss of tones since I never fixed the few tests I did.

As for Incorporated developer, the only papers I know that had those were papers made for activation development machines. I remember the old ilfospeed RC rapid 3 papers had this feature.

well I don't think it's something they actually write about on the package?

Here's what that Photo Engineer guy from Rochester had to say about it: Developer Incorporated Paper

Here are two videos I've made documenting my experience with Lumen Prints.

Saw that yesterday. Pretty interesting as it would be a perfect way for me to use that 100 sheets of completely fogged paper I got second hand.

[jharr]

After watching Joe's videos, I was intrigued enough to run a test of my own. I wrote up the results here:

[Francois]

I must admit that this is surprisingly good.
Too bad the negative doesn't last forever...

[jojonas~]

someone here in sweden started fixing theirs and got some interesting results. I'm planning to try that but haven't had any fresh chems in a good while
