Hello Julie, thanks for your thoughtful reply.
It is interesting to see that this leap in technology is spreading in our industry. I know of about 6 artists who have converted to painting with a monitor as their reference.
The interesting thing about this Apple monitor is that I think I will not even need to build the black box. The screen is amazingly non-reflective and since it is an LCD monitor, you don't really loose your colors in light or even when viewing at an angle. I have two commissions right now that I will be using it on for the first time. It will be interesting to see how it performs and to have the opportunity to perfect the distance from my easel, the angles to the easel, etc.
