I'll stick my neck out and we'll see where if anywhere this will go. Kevin's Bokeh thread, and W. Linne's Wide Open thread have pre-staged interest in lenses with signature Bokeh.
The idea will be to begin some picture post threads that show what folks have made with the different lens types. A Verito thread, Cooke Portrait thread, Heliar etc.
Give enough details like f stop etc to get an idea of what the different lens types might be good for.
The following 4 pictures were made today with a Kodak 5X7 2D and an 8" f5 Darlot Lantern Petzval. Film was Aerial Recon Pan X rated @ ASA 32, and developer was Rodinal 1:100 6.5 min.
I hope others will join in with some of your photos made with a petzval formula lens. With participation, these threads could become quite useful for those looking for a particular style or look. Someone might read through this and say, well, I know I don't want a Petzval!
