A couple from last weekend's wander round Savernake Forest near Marlborough in Wiltshire.

Both shot on Catlabs -X80 in the Intrepid 5x4.

Interesting that these were taken at f32 as I'd never come across lenses that went higher than f22. I prefer the 1st image with the pool and reflections.

Large format tends to use smaller apertures, most of my lenses will go to F/45, and a couple of them to F/64 (including the 90mm Super Angulon used for the first image).

That's interesting... is it because they have a larger sensor that the lenses can go to smaller apertures?

Indirectly. The longer focal lengths (a 90mm in 5x4 is approximately a 24mm in 35mm) mean that the same physical aperture size is a smaller f-ratio. Also to get a good depth of field for landscapes needs a smaller aperture (and/or tilts of the standards to shift the plane of focus away from the vertical), hence Ansel Adams' f/64 group.

Thanks for that explanation James it makes sense.... I only got the chance to use a medium format camera on a few occasions back in the 80's when I was at Art College.
