Fossil fuels are the main source of energy in many countries. However, in some countries, alternative sources of energy are encouraged. Do you think this is positive or negative development?

The diagram shows the detailed process of making a negative picture from step to step. In the

first

stage, you need a camera. Images are captured and recorded onto a film. All leading steps will happen in a dark room.

To begin

with, the primary process of the film is developed from the camera. Once the action is completed the

next

stage is washed in a development tank in a darkroom. When negative is produced in an enlarger, where images can be enlarged and edited. Images can be printed on photographic paper. The prints are developed, fixed, washed, and dried in a chemical bath. In the

last

stage, black and white photos can be removed from the dark room. Overall, we can see that we need three major steps involved in the making of black-and-white photos.
