Masking is the technique of masking out an area onto the paper and exposing the image into the shape. I wanted to see how many images I could get onto one piece of photographic paper, I went into the darkroom and lowered the enlarger as low as I could so that the image was still in focus. I roughly drew how big the square was on a piece of paper then measured the sides and worked out how many I could get onto one piece of paper. I cut the squares out of the black card. I also did this with circles but instead of measuring an image in the darkroom I found objects that vary in different sizes then cut then out of black card.
In the darkroom I used masking tape to hold the black paper onto the photographic paper. I covered the squares that I didn't want to expose the image into while I exposed it into each one. I did the same process with the circle mask.
I experimented with selective development to give it more of an abstract look to contrast between the formal layout and the selective development. I don't think this worked that well because you can't really see what the images are of and you can see some of the boxes around.
