Very cool!
I use a press camera bought on ebay for almost nothing... yet very handy !
It's a Busch Pressman 4x5".

Polaroid SX70 / 600 back
This a system is based on a Busch Pressman 3x4" press camera. The original standard back for film holder has been removed, and replaced by a falt base. The instant back has been made from a malfunctioning SX70 instant camera, which only the ejection system has been kept.
cheers
And I use an enlarger lens on it, without shutter. Wet plate is quite a slow process, with pauses over a second under sunlight.
Thank you @Dan Maloney !
ah, so becaue you use an enlarger lens, it's a fixed aperture, or..?
Some other "cameras" I made : https://www.flickr.com/photos/troisieme_type/albums/72157625115758010
No, is has aperture blades like any other lens. But no clicks on stops.
ah, gotcha
And it's a rather crispy lens, which gives something I like : the look of an old process, but with a definition far superior than ols photography. :)
*old
when you buy your plates, are they just ordinary glass?
And of course, the reason why a large format camera is used is that the camera has to be the size of the image we want.
Yes, you can do wet plate on ordinary glass.
But two other supports are mainly used : aluminium with black coat, and acrylic.
Basically, a material that is non-conductive and won't react with the chemicals..?
Both have a better sticking of the collodion coat, and both provide the black background, so you don't have to paint or mount the plate to view it positive.
Yes, exaclty.
Actualy aluminium reacts with chemicals. The silver bath has to be maintained more often.
what is the largest plate that you (or someone else) have created?
Some people like making things big !
And how do you deal with the left-over / spent chemicals? How do you safely store and dispose of them?
The largest silver tank I've made was for 50x60cm plates...
This must be a joy to look at !
i like the look of this camera you've made - https://www.flickr.com/photos/troisieme_type/5888618550/in/album-72157625115758010/ i would like to make something like that some time that uses 120 film, for something like ~6x17 images maybe
(I've just that we are talking about wet plate, but maybe you don't know what it looks like...

I personnaly stay low on the size. I like to have to be close to look at the details. So no more than 13x18cm for me.
@Pierre-Loup M. unfortunately, I have to run... I'll look at the transcript. Thanks so much for this info!
They look amazing... it has that american civil war look
Ian Ruther has turned a truck into a lab AND a camera.

Yes, the civil war was mainly shoot with wet plate !
So you can imagine that phoographers had their camera, but also their lab, their chemicals with them, for each and every picture they made...
Another time...
@anfractuosity This one uses 120 film.
yeah, i meant 6x17, using 120
I guess nothing was standard, until Kodak, every photographer had his own tricks
It's made with a medium format back from a russian camera (copy of hasselblad 500), a shutter from a press camera, and the lenses are olypus OM.
So we're getting to the end of the hour, and if Pierre-Loup needs to get back to work, we'll have to let him. Feel free to stay on and answer more questions if you want, though - we'll always welcome that.
I'll just say thanks to Pierre-Loup now for coming along and letting us know about how he makes those amazing photographs. I really learned a lot!
Thanks everyone for coming along too. And don't forget that next week we'll have playback designer Seth Molson here to talk about Designing Sci-Fi for TV and movies.

Designing Sci-Fi Hack Chat
Seth Molson joins us for the Hack Chat on Wednesday, October 9, 2019 at noon PDT. Time zones got you down? Here's a handy time converter! We all know the feeling of watching a movie set in a galaxy far, far away and seeing something that makes us say, "That's not realistic at all!"
Thanks all!
