A Cyanotype is where you take a photo of anything and input it into photoshop. After you put the picture in photoshop you change the photo to black and white into a digital negative. After you change the picture to black and white you print it on transparent paper. When you print the picture on transparent paper you then place it over cyanotype paper and place it in the sunlight.
The photo above I made in photoshop by changing the image I took at school into black and white. I also changed the brightness and contrast of the photo the leaves stand out.
I made this photo in my digital photography class and I used the steps I explained above to make the cyanotype. This was so cool to me because I was using a technique that photographers used back in the day.
