I will start. I am a professional photographer among other things and have been doing it for year.
Anyway. One of my specialties is Historical and Alternative processes with on photography. Some of these processes are done in the dark room and some in my photo lab/office.
Anyway here are just a few examples of things I have done for clients in the past.
These first examples are of historical processes done in the dark room. No matter how many times you do then each one is different.
These examples of Liquid emulsion are on Color paper. However this can be done on just about anything.
These examples are more alternative and again can be done on just about anything.
On tile which can be added into your rooms tile work if you wanted too.
I have also done things on Glass which is quite neat when the image on glass is mounted into a box photo frame with a mirror behind it.
So lets see everyone's talent. This should be a lot of fun.
