I'm going to try making cyanotype images, and I've just printed out my first stock photo I'll use. I put the image in grayscale and made a negative on the computer, then printed it out on a transparency. To see what it might look like, I've taken a picture of it against a mostly white background and made a negative of that:

I'm hoping that will be roughly how it will turn out in the end! Any suggestions on photos to use? I think if the original photo looks good in black and white, it should look good in cyanotype.
