Technically, a tour de force.

But (and related to my earlier post), what are you trying to achieve?
Not, I'd guess, 'realism'.

A very simple question to answer. I'm trying to achieve a personal
sense of satisfaction by creating a version that pleases me. For the
most part, that attempt was successful. I always look at a finished
project and see something else that could have been done, or something
that could have been done better, but there has to be a stopping point
with every project.

"Realism" is not, and should not, be the only objective in
photography. It's simply one style of photography that can be
followed.

Just about every good photograph deviates from true realism in some
way. If you capture a sunset, you alter realism by what you frame in
the subject. You alter realism by the placement of artificial
lighting. You alter realism by using shallow depth of field when
taking the photograph.

Would you say that Yousuf Karsh was trying to achieve "realism" in his
portraits? He manipulated the scene dramatically in his set-up in
taking the photographs. By doing so, he brought out what he saw as
the essence of the subject.


I consider edits of that kind a form of art in their own right.

I would consider it to be pretentious on my part to call it "art", but
I do consider it be a form of artistic expression to make the attempt.


Thanks both for those explanations - makes sense.

My first reaction was Detroit Diesel, but the piston and rod is too
big. The Detroit Diesel was in fact designed by Kettering. Kettering
also designed the similar but larger series of engines used by ALCO in
their locomotives. Some ALCO engines used that style of arched bearing
cap on their connecting rods, so I would say the assembly comes from
an older ALCO locomotive.


Thanks. I find that 'scaled up' engineering fascinating.

Just about :-) Incredible. This:

is a couple of miles from my home. Doesn't actually look that big in the
video. Up close, it's quite a thing.

yep, me too. I have somewhere some photo of the new 50MW 70,000PS
two-stroke diesels in the new power station in Atherinolakkos. These
beast burn ~50 tons of mazut an hour! (A much smaller 11MW 15,000HP uses
11 tons an hour and the cylinder liner is higher than a man). The boiler
of an 125 MW brown coal fired plant is as tall as a 10 storey building
and can generate superheated stem at a rate of 300 bar and 500 deg.C.!
Much more impressive is the boiler of a 300 MW power plant but I haven't
been in one. The output is 400 A at 400kV! That electricity is being
trasmitted to Athens (500 km away) with lines with a 99% efficiency.

That's what happens when you get cheap money.

The most economical distribution line has losses = to the rate of
interest on money used to build it.

yeah, especially the people who protested and demanded the tranmsission
line would pass elsewhere and not through their properties. The
transmission line cost, I think ten billion drachmas, and for a couple
hundred meters couldn't reach the Athens substation. It goes without
saying that this was taken to court, which justified the utility, so
under police escort (!) the linemen connected the final meters of the
line, and it was energized.
