Photo Booth Process

[Stephen Frizza]

Today was an Awesome day for me. It was the first time I ever had my portrait photographs created by an Analog photo booth. please see image attached. I placed my fingers up in a test sequence. I a curious what exactly the chemical process is that makes these? the paper is fiber based and is sepia in tone (not black and white) as the booth says. I am aware there is no negative the paper is the exposed material. I am curious who is making the paper? I'm guessing it has to be a very fast paper? secondly would i be correct in guessing it is normal black and white which is some how reversed? it doesn't look anything like black and white reversal paper. Also is it a common occurrence to get slight chemical streaking? or is this a lousy processing machine? so many questions but i am wanting to start a project using this medium.

It's B&W paper reversed in a crude dunk dip system, they always smelt of chemicals, but often used a fogging reversal bath which gives an image less prone to atatck by any chemicals left after the brief rinse steps. See this site.. There's plenty of details about the booths.

I know of this site and it does not answer my questions. I have applied for membership....waiting response. I would like to know A, who is the manafacturer of the paper not who is a reseller, ide also like to know what the chemical process is called. (Ra-4,C-22,C41) I know it isnt those! but i was wondering if it does have a (code) name. and if i could ide love a disection of each chemical bath what is the chemical make up of the dev, reversal...etc

Have a look at these two APUG videos if you hadn't already done so:

There's no specific code name for the process as it's unique to the Photobooths, probably with slight variations between manufacturer but it's closely related to many older commercial B&W reversal processes.

This thread asked about paper, and it's more the slitting etc than the speed, as 6-10 ISO with a flash is quite manageable at the distances involved inside a photo-booth. PM the OP and ask what he's using.

Once you know the time scale & temperature for each dunk dip bath it's easy to come up with chemistry that will work.

if i remember correctly
there is someone who sells
photo booth parts on ebay
maybe you can contact him
and find out the answers to your questions ...
and then post back ( or bring HIM back with you )
to let us all know what happens inside the box

you can find him just by searching "photo booth"

good luck !

I don't think this question was every adequately answered. How does one reversal process b&w paper? There's an analog photo booth in my town, and I think I'm going to try to get a hold of the owner/maintenance guy.

But seriously, what's the answer? Is it a classic dev/bleach/clear/fog/dev kind of reversal, or something different?
