Lol… Ulrich, that is a fine offer and I’d love to meet you and your wife but sigh … I’m afraid I’ll have to decline. I hope you understand.
Petra… back ten or so years ago, when I did a lot of photography, I frequented a camera forum and there was a lady by the name of Petra on that board. She was from… oh, I can’t remember now… I believe Sweden… where has the time gone… anyway, she was a very nice person and loved photography.

I wish I had you guys problems. Mine are painful as regrds backdrop. Due to the nature of my layout, my 2 foot wide shelf layout is in the ceiling area and the roof tumbles over the shelf at about a 35 degree agle! Bummer.
I am having to hand paint my backdrop with an eye to changing shades preferentially as any scenics rise to the sky. It will never be perfect, especially when viewed in person as many here note. I have redone some sections twice and am convinced it will never be more than marginal.
However, in a controlled photo, I can pull off some limited magic.
What I had to deal with…(last year as I started)
A back drop slanted forward at the same point on the layout as above, but with the right angle and lighting.
A long way to go, but OK for photos, unless you are there in real life.

Richard, I had one of those ceiling slanted backdrops one time. At the back of the benchwork I had about a foot of vertical before the slope started on the lower side of the RR, but on the other side, only about half that. Made for some interesting fitting structures in on that side.
Richard,
Under the circumstances, your backdrop is very effective. It’s also a good example of locating the horizon and the height of the “scenery” on it really compliments the real scenery in front of it.
