Mind, doesn't the appearance of a scene depend on other factors too? With film, a scene shot on Kodachrome looked quite different from the same scene shot on Agfa, and different again to say, Ektachrome, Fuji, Perutz, Barfen or any other brand one might care to mention. Didn't we each have our favourite brand?
If one is preparing an image to print rather than to view on a monitor or project it, it would need appropriate processing to achieve the best possible result. A lower contrast image is needed to print onto paper, and even different papers cope with contrast differently, hence the range of paper options given by a printer driver!
Black and white photo printing papers come in different grades to allow for differing contrast in the negatives, so at the end of the day it is all about compromise, and as DrO says, we all see things differently.
Regarding image size ration (16:9, 4:3 etc.) I believe it is a bit of what we are used to. The 16:9 TV screens looked very odd when I first came across them, but now we have got used to them 4:3 seems strange!

MrB's building above looks right to me.

I am currently shooting macro with Pentax 50mm M 1.7 + extension tubes, and I am rather happy with the sharpness.

I'd avoid the K-m, that is the most dated of the three and sensor-wise of a lesser quality.

The only processing of the in camera jpeg was to reduce its width to 800 pixels wide.
For what it is the sensor quality is great! Personally I like the K-m because it is one of the lightest Pentax DSLRs should every gram count so great to carry on rides/hikes.
So if the price is right and it is a good one, don't discount getting one.

I never changed to a more modern film body (ie stayed with a K2, ME & MX) for that very reason. The newer ones appeared so much more fiddly beside looking more plasticy; I'd be more than happy now with a digital equivalent to an ME that worked well with M lenses. The only other features it would need are a preview button for depth of field, an ISO button coupled with an exposure override. Not worried about shake reduction, fancy filters (but a digital red/yellow/green wouldn't go amiss) and a colour/mono setting. Also the ability to take RAW / JPEG / TIFFS. That's about it. A super version might also include an LCD screen!

Rumours are though that commercial applications will take almost as long as the Pentax full frame.
