A few weeks a year I get a fine angle of sunlight just at sunset through my upstairs north facing window. Just as my bride called me to dinner I saw this pattern and quickly grabbed an 8X10 holder. This is done with a 5X8 f4 B and L made Petzval and a Century Studio 4A camera. The outfit including the Ilexpo shutter is for sale but I don't want to ship it. I'll be in central California next week and could deliver in the bay area.
