I have been struggling for some time with lighting in my studio. I think I have finally come up with a solution that should work for me. My research led me to the conclusion that I should be painting them in similar lighting conditions to how they would be displayed. Even though this could be just about anything depending on what home they finally end up in, the galleries tend to set the standard. Galleries are moving to led lighting for economic reasons, as well as the lack of damaging heat and uv. They also tend to use lights that are 3000K which just on the edge of warm and cool but shifted slightly warm. The cool lights tend to be to harsh for artwork and are mostly used in jewelry stores.
I also had a problem with intensity but this resolved when I put PAR 30 floods in my track lighting (75 watt equivalent). Their colour is 3000K. I use two of them shining from the ceiling onto my easel and palette.
This solved an additional issue that I had with my photographs. I had never been able before to photograph indoors and usually ended up using the scanner on my printer. I had not been totally happy with the results because some of the colours were a bit off. Now with the greater intensity, I can put my camera on a tripod and photograph the painting right on the easel in the same light as I paint in and the photo comes out closer to the original than I have been able to do before. The settings would be different for different cameras but mine is set for a white balance of 3600K.
