Latent image becoming a real negative

Developer makes a latent image appear. The time it takes to appear depends on the temperature. Stop Bath stops the devloping process. Agitate for at least 15 seconds and then recycle or dump. Agitate for 2 minutes and then let sit for 2 minutes with New Fixer. Agitate for 3 minutes and let it sit for 3 minutes if it is Used Fixer. The fixer makes the image light proof. Fixer Remover rapidly removes the fixer after agitating for 1 minute and letting sit for 1 min. Then wash it with water for 5 minutes. Tank - the lid is chemical proof. The cap is light proof. ad the center column must be used properly. There is the reel and then the thermometer which is darkroom calibrated.

How an image is formed

The camera obscura can't capture objects in movement and you can't focus in on things and have to get parts you may not want in the picture.

An emulsion is a liquid stuck in a solid. Light colors come out dark on the negatives and dark colors come out light. The reason it does that is because when you take the picture, the crystals bunch up real tightly when there is a light color and when there is a dark color the sort of spread out which causes it to be light.

Digital cameras and film cameras both have a series of lenses taht focus light to create an image of a scene. But digital cameras have a built-in computer and records images electronically.
