galaxy dry plate kickstarter

This will surely be a wake-up call for frequently mentioned (but who I have never be able to contact!) facility in one of the newer countries in the EU which apparently has a production line for medical/scientific customers. They are orthochromatic too!

Perhaps they should have thought about the many owners of 1/4, 1/2, 1/1 plate cameras who do have perfect plate holders available?

This is how Eastman had started, maybe they are in for a long ride, hopefully. I was also bewildered by the explanation on the orthochromatic material effect on the portraiture. I shot wet plates from 5 years now and I believe the effect is the other way around.

... or the subject can just wear "concealer" ?

Orthocake, as opposed to Pancake.

I contacted the people making the plates & got this reply:

Hello Chris,
thank you for your interest in our project.

We wrote the description based on our experience.
Thank you so much for your input. We are still doing tests and will post some results later.

Best regards,
Team Galaxy

I believe I see a source of confusion. Wet plate emulsion is not orthochromatic. It is blue sensitive ( sometimes called "colorblind"). Orthochromatic emulsion is sensitized for all colors except orange and red. Before panchromatic emulsion, it was generally considered a great improvement over colorblind emulsion for portraits. Orthochromatic emulsions are used with a yellow filter for full effect. It has a few idiosyncrasies but there is a lot of info on ortho film and portraiture in the historical literature, much of which is available online.

[Peter De Smidt]

Sure, but red will still be darker relative to the representations of the other colors with an ortho plate, and since many blemishes are red, they will be darker relative to the other parts of the picture than if pan film had been used. As a result, they will stand out more, not less, than they would with regular panchromatic film.

I've tried to get information if it's possible to make a "ambrotype", false positive image on these plates, but no answer..

[Nodda Duma]

Funny. Reading this after coating a bunch of dry plates last night.

it IS, but you need a reversal developer to make them with silver gelatin. at the moment
rockland colloid is the only company that commercially makes the developer and they sell it by the gallon
for their sivler gelatin tintype kits/tintype parlor. i've made under exposed dry plates to try to ambrotype too,
but it doesn't really work as well ...you can also PRINT on these, or any dry plates ..
