I don't have an issue with including the foreground but perhaps I'd burn it in slightly as it's a bit bright.A very pleasant image. Although it's not the same composition, it reminds me of John Blakemore's Lathkill Dale.
If I may be very picky, I'm not quite sure about including all the very detailed foreground.
The 180mm Xenar is a Tessar design, they give their best overall sharpness at f22 corners and edges tend to be slightly soft at f16 but with this FL on a 5x4 camera this wouldn't be an issue.James, I notice you used an aperture of f16. This is practically wide open on a 5x4 camera. Just wondering why you didn't stop down more, which could have brought the foreground into sharper focus.
If the lens is of sufficient quality, the format makes no difference to when diffraction becomes important. The linear size of the Airy disk in the focal plane is a function of f-ratio and wavelength alone. Approximately the size is f-ratio × wavelength / 1.2, and if that is bigger than the film grain then you are diffraction limited. For the very finest grain films (e.g. Adox CMS-20) diffraction becomes important around f1.2!At f32 and f45 some say LF lenses are diffraction limited and lose sharpness but in practice that extra DOF may be more important. John Sexton uses f32 and f45 at times and his work is superb.
In earlier threads I've posted images in quite windy conditions and with either slow shutter speeds or multiple (fragmented) exposures.On an earlier comment, I'd like to say we are all engaged in a war between wind speed and shutter speed.
