My limitations: Use sticky notes; Use round shape; Use photography.
Use round shapes and Use photography made me think of Pop art and Andy Warhol's Marilyn Monroe. screenprintting.https://www.moma.org/collection/works/61239
I also researched more about Pop art.
First, I found a picture of Marilyn Monroe and add color halftone filter on it in PS. So the picture was composed of many circles after editing. Then I printed the picture and used it as a reference.
Second, I cut sticky notes into different sizes round shapes and put these circles as the picture's pattern.
Finally, I took a picture of my sticky note circle Monroe and edit the picture in PS for example adjusted Curves/Hue/Color Balance/Exposure.
Thanks the three forces give me the change to salute to Andy Warhol's work.
