is the film same with the negative? and is the film / negative sensitive to main light?

Question

do you enlarge the film or negative (?) before you develop it? thanks!!!

Answer 1

ok , let me see if I can answer what I think you are asking...
The roll of FILM you purchased is highly sensitive to light, hence how the exposure (image) is made on the film through the shutter of the camera. Once the roll of film has been used, it has been "Exposed" (this is why they "36 exposures" on the roll, or what ever number of frames you can fit on that roll). Still light sensitive. You then take it in to have it developed, this is a chemical process that washes away some of the coating on the films surface to reveal an image, which is then referred to as a negative which is where you images are made from.
So, to answer your question, the film is the same as the negative and is only sensitive to light before you have it processed / developed, once developed no worries about light.
As for the enlarging..you put a negative in an enlarger (AFTER developing), so named. It uses a lens to "enlarge" the image to the size you want it "printed" at....8x10 - 11x 14 and so on. Or you can have it scanned and computer enlarged.
Hope this helps.....

Answer 2

Good answer above...I will add that in color transparencies, the film is developed so a negative image appears first, then chemicals and dyes change the negative to a correctly colored positive. When you project that through an enlarger, onto special paper that allows for postive rather than negative exposure, you get a print that is likewise positive and correctly colored. While negative and transparencies are no longer light sensitive, it is best to store them in the dark because sunlight eventually will negatively (couldn't resist the pun) affect the quality of the image.

Answer 3

You develop film [light sensitive]
You enlarge a negative [not light sensitive].
However, the enlargment paper is light sensitive and can only be exposed to red safe-lights.

Answer 4

You call film before you expose it and negative after exposing and developing, because the image in Black & White appears the opposite; what ever is white you see as black, and what ever is black appears White.
In color film is the same which ever is red appears cyan (complementary color), the green appears magenta and the blue as yellow.
The film itself is sensitive to light, but the negative (which is developed already) is not.
You enlarge the image from the negative which is already developed; you can not enlarge the film itself.
