I'm not sure of the proper term, but I'm wondering what some of you use for the hood you hide under while viewing your images through the ground glass. I'm very new to LF and in the very few photographs I've taken, I've simply used a black sweatshirt with the neck over the film holder. This can get quite hot on summer days (as I discovered at Smith Rock near Bend, OR this past summer). I tried using a t-shirt but it really wasn't dark enough and it wasn't very easy to really see the image. Thanks.
