Taking a photo with a bottle

We are 2 partners working on this project: Léa Degos and me. 

We have chosen this subject because for me I would like to be a photagrapher and for Léa it's original and she likes this idea to take a photo in a different way!
Taking a photo with a bottle is in the principe of a pinhole.

The operation of this device is similar, on principle, to that of the eye.

When we look at an object, it reflects light rays enter the eye through a hole, the pupil, and reversed image forms on a screen, the retina.

We have made a pinhole camera with a bottle: - we cut the top of the bottle

  - we paint in black inside of the bottle

 - we put a light sensitive paper inside

 -we make a little hole in front of the paper

We try to take a photo of one tree in our hight school and we have to develop our images.This picture is in negative.

To develop a photo we need: -4 baths ( developper bath, stop bath, fixer bath and water bath)
                                               - A safelight lamp
                                               - a dark room

                            
In the futur, we have to transforming our negative picture in positif. We have to explaining to you how we do this!
