On the first photogram, I used the layering option to combine two separate photograms that I had completed. I had used a bouquet of flowers, rolling it along the scanner as it scanned creating a continuous effect and then I inverted it. I layered it with a photogram of some jewelry creating the finished picture.
The second photogram is simply a scan of a decorative metal basket using the stylize filter and then an overlay of the previously mentioned bouquet.
The third is my hand holding the same bouquet, inverted and then posterized for a pop art effect.
