Cropped image used for halftone
The next tutorial in the book builds on the mezzotint exercise I did yesterday. This one uses a recognizable image rather than a random pattern as the halftone dot for the mezzotint effect. To the right is the stock image I used to make the halftone dot, after cropping and resizing.
And here is the image I applied it to for the mezzotint effect, along with the final result:

Flowers with other flowers as the halftone dot image
In creating the halftone dot, I started with a simple resized version of the original, but that didn’t work well because I had too much white in the background. I tried again with a closeup of just one section of the image. That worked better, but the image was too flat when I converted it to grayscale. I finally remembered that one other way to get a good grayscale is to look at the channels. The red channel yielded a much nicer grayscale image, so I used that instead.
I’m not sure this was a good set of images to use, but for the purposes of this project, I didn’t want to get too hung up on the image selection. It took some fiddling to get the output resolution right so that the final result was still recognizable as flowers. The technique itself might have worked better on an image with a bit more contrast.
