Yes. If you reverse both elements it gets softer. Reverse just the rearmost and it gets both softer and the edge distortion goes wild.
So with this lens, which covers 4x5/5x7 easily, the petzval design keeps only the very centermost point in sharp focus and everything else very quickly goes first into softness and then soon after that into big time aberrations -- everything streaking away from the center.

The is a 1930 Hubmobile made at a place called Fort Apache near Holden Beach, NC.
Made with my old Speed Graflex with a Wollaston Meniscus 135mm lens wide open.
I guess this is "Galli Style" but maybe the subject isn't.
This is the front half of a projection lens I found in the bottom of a box, delaminated and separated, but "what the heck", I taped it to an Ilex shutter and tried it anyway.

MKillmer, Very nice image great use of your personal creative skill and understanding of what's possible, with what's on hand.... Some are paying big numbers for a lens that is able to give an image like this... impressive.... Bill
