liquid emulsions and glass plates

[rkmiec]

a few questions.if coating a plate with black magic or liquid light is the plate going to be a negative or a positive.i am thinking of experimenting with a pinhole camera and glass plates.but it seems that those products are for printing not taking photos.if that is true are there any emulsions that are for a negative.i am new to the idea of glass plates.i have read some threads but this specific question isnt answered.ultimate goal would be contact printing with the plates.also how about speed.in pinhole every stop is like an eternity.

This guy made a 'glass' negative using liquid light but he used a lens.
It's SLOW.

He has some other images using this method posted as well. Nice stuff.

Good luck.

hi there

i made glass plates to exopose under an enlarger coated with liquid light.
i have also made dry plates ( camera plates ) with the same stuff.
it is very slow stuff, around asa 1 or 5, and with a pinhole, it will be very slow
you will get a negative in a camera, just like photo paper, or film.
make a good subb layer. i have had good luck with clear gelatin,
food grade worked for me.
you can also use urethane, but it will yellow over time.
just make sure your plate is really clean and you should be OK.

not sure if you have been over to here: http://www.alternativephotography.co..._dryplate.html
mark explains it better than i ever could

have fun!

Read the alternativephotography.com article. It explains everything well. Again it is a very slow medium ASA 0.5-2.0 but its a lot of fun to work with.

Oh yeah, pour your plates over a tray or lots of newspaper.

And good luck!
