My first Rayogram / Photogram
This photo was my very first attempt at producing a photo in the darkroom. It is very over exposed and it has little or no composition, all it has is a white strip to the far right and 5/6 of the page is covered with black. there are a few shadowy white lines over the black part of the photo, it is very ghost like. i would say it is a very abstract picture. the white shadowy lines are very translucent. there is a pattern in the bottom left hand corner of grey and white lines horizontally alined over each over. if i was to do the picture again i wouldn’t stick it in the developer chemical as long.

How to make a Rayogram/ Photogram
Step by
1) Find a dark room to develop ure photo’s. then get some glass plate negatives if that the type of photo you want to produce in my case it was.
2) You put the glass plate negative on top of some light sensative paper (shiny side up). Then you change the amount of seconds you want to exposure your picture for and the apture and you press the button. In my case the apature was already set, and i exposed my picture for 10 seconds.
3) Once youve exposed the picture to the light you get the light sensative paper and put it into the developer chemical for about a minute but no longer otherwise ure ruin the picture.
4) You put the light sensative paper in the stopper chemical for 5 seconds to stop the photo from developing.
5) Put your photo in the fixer for about 2 minutes, If you dont put it in long enough the picture will begin to change and you dont want that to happen.
6) You need to put your picture in a tub of water to clean the chemicals of. If you dont do this properly the chemicals can damage the picture.
7) Use the squeege to get rid of excess water so the water doesn’t damage the picture. then you hang it out to dry.
Glass plate test stripes
First we wanted to test the effect of exposing a glass negative for different time periods with a set apature so we would know the best exposure time to use to develop the picture. So to do this first we set it to 2 seconds and covered 1/5 of the picture with and book and we exposed the light sensative paper for 2 seconds. Then we moved the book along and cover 2/5 of the light sensative paper and exposed it for a further 2 seconds ect. we did this untill we exposed the picture for 10 seconds. From this we picked the best exposure time to exposure our picture for with the set apature we had which was 8. Then we had a go at developing our own picture with our chosen exposure time and set apature.

This screen shot is me showing the difference of size of dpi and how it effects the negatives. dpi means dots per inch. dots per inch refers to how many dots make up that photo so if you enlarge a photo by x3 then the dots per inch will enlarge by three times e.g. if you have a centre metre square that has 100 dots per image if you enlarge it by x3 then you would 300 dots in the image. when printing for more dots per inch in the image the better quality the image is. pixels determind the quality of the picture . the more pixils in the picture the worse the image will look.
