Photograms and Rayographs
What is a Photogram/Rayograph?
Photograms or Rayographs are mages created by placing objects on a piece of paper covered with a light-sensitive surface and putting them in light. Where the object touches the surface it will keep the light from touching it , leaving a white or pale grey space where the object would be( the colour depends on the objects transparency). If light can get underneath the object the surface will become darker than the rest of the space but not black. If there is no protection at all the paper will turn black.
Anna Atkins created photogram-like images using paper that could be put in sunlight and developed and fixed in water. Photograms or Rayographs are the result of experiments in the darkroom where chemicals (Developer/Stop/Fix) are used to activate the picture which is finally washed in water. Rayographs are the name given to photograms by the artist Man Ray. they are the same type of image.
How do you make a photogram?
first choose a few objects and arrange them on the page how you want them. Next you shine a light on the paper for about then 10 seconds then take it to the first chemical called 'developer', leave the paper in the 'develop' for about a minute then drop it in to the 'stop' for a few seconds ( remember to use the designated tongs for each chemical) after the stop drop into the fix for about 5-10 minutes,i put mine in for around 6-7 minutes, now pick up your image and washing with running water then put in in the squidgy and pull it out the other side now you photogram/rayograph is done! :3 all you need too do clip it up by the left-hand corner and leave to dry
The main chemicals used in the darkroom are developer, which causes the silver iodide on the paper to get darker if it has been put to light, and fixer, which removes the undeveloped silver iodide from the paper. a chemical is used to stop the development it's called 'stop' , and is used between the developer and the fixer
This is one of my photograms. i used objects such as a chain.metal rings and a wooden block. i like the faint mark that the chain leaves because its not a straight line and it shows every little ring so it shows that the photogram paper can pick up small detail, i also like the imprint thats the object in the top right corner but it is faded so perhaps i moved it during the period on which the light was shining on it when i look at it i don't see much negative space i think the balance of negative and positive space is good.
These Rayographs/photograms are made by the following:
