This has been a strange but interesting week so far. I started the week working on a large relief,a large wax cast and a bronze turtle. But the week evolved in a different way, I spent part of my time building a light box or exposure unit for my partner Barbara's studio. I've never built a device like this before since most of my training is in sculpture not silk screen printing. I do remember students building their own light boxes when I was at art school. So I decided to look at videos recently to familiarize myself with this device. It seemed to be a fairly straight forward building project except that I was uncertain as to the light intensity needed to provide an even,properly developed screen. The other issue was time. Was it prudent to use a timer that would automatically shutoff the light or a simple on off switch. At publication of this post, Barbara has not tried using the light box yet, perhaps Saturday. I'll let you if it worked.
