What is film in easy English? Many individuals question me this, mainly because practically most of the articles out you can find style to impress people that maybe not know any chemistry. Therefore I've attempted to "translate" the essence of the definition in to simple English: Final film is really a page with this plastic, lined with a blend of substances sensitive and painful to mild (silver halide salts), bonded by gelatin.

How big is the gold halide salt crystals, establishes the sensitivity, comparison and decision of the film. Shade film usually contains three layers of sodium deposits, while black and bright film generally includes one layer only. This can be a very fundamental explanation and by all indicates is not very technical.

His "film" if we could contact it therefore, was made with a polished pewter plate included with "bitumen of Judea", a petroleum derivate Fotografo Vitoria ES.

With contact with light bitumen hardens and after the coverage the unhardened substance could be washed away and after polishing the menu was ready for printing. He ended up with a dish that appeared very much like the after utilized in Counteract printing: the refined plate could be pushed on a pad of printer and an image could be produced on a sheet of paper. Interesting isn't it!

Film has been changed by storage cards, therefore the problem is: how crucial is final film nowadays? Many people genuinely believe that it's not essential at all, but I say it's really important. A photo opportunity on film is basically real: it's there, you are able to feel it and save yourself it in your desk's drawer. An electronic image is really a cat that now's there and two moments later it will disappear making no track of their existence. Last week-end I gone with my family on each day trip. I picture about 120 photos and abruptly towards the conclusion of the afternoon, my storage device turned corrupted. Not just I was unable to capture anymore, but I had lost all of the 120 pictures...
