Mahalo Dana!
Since I posted my querie about projectors, I received some more input. A photographer in Palm Beach FLA said the Mitsubishi XL9U was the way to go, and, Noellez, he said that Proselect software is the program to use. They offer a free trial to download, and looking at the site,
www.timeexposure.com, it looks like the way to go.
I researched the Mitsubishi projector and contacted the local dealer. He said that better than the Mitsubishi was the Sanyo PLC-XU74. He said it's brighter and has more contrast. He's bringing it over tomorrow to demo it for me.
I'll let ya know how it goes!
