As you may know from visiting my site, I paint with Flashe Paint., a vinyl acrylic paint that is reminiscent of old tempera paints, paint made with egg yolks and primitive painting grounds, the earliest materials used to paint. An example would be cave paintings. Flashe Paint is matte, velvety and opaque. There is more about Flashe Paint and how I got started using it in the November Archive entitled What is Flashe Paint. One afternoon I was looking at the painting, Asian Vase and I noticed as I moved around the room, the colors and shadows of the painting changed. As the light changed, so did the way the painting looked. Not an overpowering change, but a subtle difference. The vase seemed to really pop in the painting. The napkin seemed to fluff up and the fruit looked sharper. The red berries looked as though I could pick them off of the painting. A few days later, I was sitting at my computer in my office area. My studio is directly across from it. I get up rather early. I love to watch the sun rise in the morning and watch the day break into it's magnificent colors. I was looking into my studio at the work in progress painting. As the sun moved across the morning sky the light changed as it came in the window, so did the way my painting looked. The light appeared to catch the sunlight on the pond in the painting. The colors and shadows were changing with the movement of the light. The pond became less brilliant as the outside light moved across it. The clouds in the sky weren't as vivid. I started looking at my other paintings. Some are acrylic and some are oils. My paintings are fairly colorful. For the most part I like bright, bold colors. Looking at them from different angles nothing was changing. They weren't reacting to the light in the same way. Why are the Flashe Paintings changing their values and the other ones aren't? A few days later I was sitting in my office. I have The Rebel Daisy hanging there. I looked at it. It was mid afternoon. There was a good bit of light coming through the window. The painting looked vibrant as though I could lift the vase of daisies out of the painting. Later in the day as the light waned outside, the shadows changed on the painting. The other Flashe paintings were also following the light. The acrylics and oils looked the same. No changes in value or color. What is the difference? Okay, What am I not seeing? I looked at another painting, Flowers in a Vase. I painted that with Flashe Paint. The colors and values weren't as vivid. I looked closer. On that painting and most of the ones I had painted I would finish the painting with a semi-transparent glazing medium for the acrylics and some Archival lean meduim for the oil paintings. By using either one of these mediums on the paintings it would change how the light reflected on the painting. Each of these mediums have a glossy finish so when the light would hit the painting, the only thing that reflected back was the glossy finish. One night on the First Friday Art Walk, a lady was admiring the Asian Vase painting I had displayed at A Robin's Nest of Antiques and Treasures and Art Gallery. She commented that this was a painting she could stare at for hours. I started talking to her abut the painting and asked her opinion about putting a glaze on it. She looked me straight in the eye and said very adamantly: " Don't you dare! You'll ruin it!" Her response surprised me. If she felt that strongly about it maybe I should follow her advice, which I did. Finally the mystery was solved. No glazing meant that the light would reflect back into the area it was hanging. Bright light, dim light or any light would be reflected, not filtered out by the glazing medium. The moral of the story: I will probably continue to use a glaze on the acrylic and oil paintings. They look better with a glaze. The Flashe Paint, I'm going to leave unglazed. Some times it is a matter of personal preference. Some people like glossy and some like matte. The choice is yours.
