Daguerrotype Becquerel Development and Modern Film
Becquerel daguerreotypes are developed using orange or red light over a period of a few hours. Often the film or plate holder used during exposure is covered by a red or orange film such as Rubylith. This is then exposed to the sun or under an incandescent lamp for several hours. With a well prepared and exposed plate the image can start to be seen within the first 15 minutes of development.
Can we use that process or similar one with modern film ? May be Ortho film ?
Thank you for the tip Molli :D
