Rather than a camera use a smart mobile phone. I took this on my Samsung smart phone which has Pro camera settings with the lens at HO scale eye level. Smart phones, being thin, have the advantage they can be set almost anywhere on the layout.

My own smart phone is a Google Pixel 6a. The phone camera doesn't have pro settings, but it can save its images as RAW files. These are .dng files and amazingly they are compatible with my ancient iMac.

The viewpoint here is a little low, as if the camera is at waist or chest level. Perhaps a reflex camera with a focussing screen on the top. All of the lighting and shadows here are from the lighting rig, I am sure I have got this in just the right place. The trees are out of focus on the backscene, and rendered further out of focus here.

Another slightly low viewpoint, the photographer would be standing on a barge in the basin.

A higher viewpoint, closer to that of a person. The buildings are about 80 mm behind the wagon but look so much further away. The shadows on the chimney stacks align pretty well with those on the wagon.
These three photos are RAW files from the Pixel 6a, with the jpg files for WT created in the iMac. I rather like these photos, I think the colours have a slightly soft appearance.
