Cyanotypes
Cyanotypes- a photographic printing process that gives a cyan-blue print. There are two chemicals used in the process: Ammonium iron and Pottasium ferricyanide. These two solutions are then mixed together and then applied to a receptive surface and allowed to dry in a dark room. Cyanotypes are sometimes referred as blue-print. The procedure is where objects are placed on the paper and when natural light reflects on to the paper, after a while it leaves a print of the objects. When it is exposed, the iron in the exposed area will reduce, this is what makes the print on the sheet. The extent of the color change depends on the amount of UV light received, but results are usually obtained after around 10 minutes. Sir John Herschel discovered this procedure in 1842; he was a scientist and astronomer.

This is my first cyanotype attempt. I like the tonal range in the photo as there are some darker and some lighter parts in the photo. However, most of the objects are blurred, if it was more in focus it would seem more better. Also, the composition of the objects in the photo is good, the arrangement is not too messy. Moreover, we can see each object in its own place; if i spaced my objects out more widely, or i cropped the top section, the image would seem more appealing to view. Also, I think if i exposed it in the sunlight for a few seconds longer then the depth of field would be stronger. But, on the day we experimented with cyanotypes there wasn't much sunlight and it was quite gloomy, that's probably why it didn't come out as good. Nevertheless, if i do try this again, i could choose a day and place when the right amount of sunlight is able to expose my cyanotype. The texture of the image if rather soft and smooth.
