Calotype process

the process of making a calotype is similar in a way to the process of making a photogram because they use the same method however a calotype requires you to have an image already that you want to invert. The way you make a calotype is by getting an image in black and white that you would like to invert and then placing in a press with a glass top so that light can still get to it then you place the photographic paper below the image whilst the light is off so the paper doesn’t start to develop then place the glass down on the image so that it it does not come out blurred then set the timer for around about two to five seconds so that it doesn’t overdevelop. Then take it through the development process like you would for a photogram or pinhole image and when it is dry it should come out inverted compared to the original image.
