Brothers and Sisters of Carderdom:
I sit before you today not as an erudite scholar of artistic history, nor a learned practitioner of all the ism's under our cool and warm skies, but as a simple woman, unassuming and pragmatic, forceful when required, yet sensitive and compromising.
But seriously folks, I came up with this tool that some may find helpful. My challenge was that I wasn't satisfied with any photo I printed with the intent of using it for a painting. I liked the photo on my monitor. But trying to match the color was difficult because of the light emanating from the monitor. If I put a dab of paint on paper or even just using my brush, I ran the risk of smearing paint on my monitor and the paint was too dark, backlit by the light from the monitor.
So here is what I did:
I took a big piece of opaque card stock, specifically what I used was a sheet of canvas paper. It's important that you use something thin, so there is no shadow. I cut a 2 inch by 2 inch square out of the middle. I taped an 8x10 piece of clear cellophane over the square. Now, I can put a dab of paint on the square, hold it up to my monitor and check the color with no back light. I am calling it, "Sue's Peekie See."
I just started using it but so far so good. It seems to work pretty well. In the photos, I had to tape Sue's Peekie See to the monitor to photograph it, but when using it, just hold it up of course.
