I am kind of cramped into my studio and can't get very good photographs. My camera is mounted on a tripod and I'm clicking the shutter by a wireless remote. I didn't fiddle with the camera as much as I fiddled with the painting, so I'm apologizing for the dark and murky photos here.
I like to draw straight lines with a level. It is so much easier than trying to line up a ruler
I have my overlay attached to the canvas at the top with 4 C-clamps and I can pull it over when I need to check something. I am not positioned exactly in the same place as I was when I took my original photographs so looking at the setup is confusing because it is slightly off. I got the bright idea to put the large photo on my tablet and I can use that to see very close up details that I can't figure out by just looking at my big photo that I printed out. The tablet is great because it has that bright light inside and I can go very close up and really see what I'm trying to do. Instead of trying to print out pieces of the original photograph I can hold the small tablet in my hand, or put it on my work table and really understand what I am looking at. I like to get as accurate as possible, especially in this stage.
Line work is finished and I'm stopping for the day to do some other projects. More will be revealed!
