I meant to add that that lesson still stands out very strongly even from
55 years away. :-)

Your comments about life being hard on engineers suddenly transported me
back to highschool and my mechanical drawing class. I'm not sure how
the teacher found him but he invited a Ford truck engineer into the
class to talk about the importance of mechanical drawing to mechanical
engineering. While he was speaking, an important question occurred to
me. I asked him how it was possible to draw in the fuel line running
perhaps a round-about route from fuel tank to engine and, in particular,
how would you determine the length of the fuel line from that drawing?
He got a big smile on his face and said: When the prototype truck is
being built on the factory floor you go down there with a long piece of
fuel line and then do whatever you must to run and install it from tank
to engine. When you're done you remove it, stretch it back out and
measure it and mark the length on the drawing.
I felt pretty stupid. :-)

I've always considered the color quite accurate but now I have some
minor
doubts. My wife wanted to go shopping for tile for the kitchen
backsplash. She asked if I'd take a picture of the (predominantly) gray
quartz counter top (but also speckled throughout with bits of white,
black,
tan, very pale yellow and browns). To her that meant I'd walk in,
take a
shapshot in the kitchen and 5 minutes later produce a print that you
could
lay on the counter and not be able to tell that it was there. Then
she'd
know if the backsplash tile was right for the countertop.
I did indeed try something like that and disabused myself that it was a
simple task in about 3 minutes. Daylight was streaming in from the left
rear (patio sliding doors) and tungsten from above... ugly colors. I
decided that I needed to use flash and simply overpower the tungsten.
Overpowering the tungsten was easy. But the on-camera flash created
a huge
reflection from the glossy quartz. Time to get the flash
off-camera... go
find the Canon off-camera flash cord (which also works with Oly) and
get a
seemingly good color image. Wait. I want to lay this on the counter
and
not be able to see it. The pattern on the print needs to be exactly the
same size as the real pattern. Back to the drawing board. Lay a
ruler on
the counter to measure off 7" to make a 5x7" print. Get out
stepladder to
get exactly the right distance for 7" to exactly fill the frame.
Take test
shot. Hey, it looks great on the screen. Now time to make a print.
I've
always assumed my HP printer with HP ink and HP paper makes good and
fairly
accurate color. Well, that ain't so... or is it? Seems I can't
carry my
24" Dell flat screen into the kitchen to actually compare the colors.
Adjust color, make print, adjust color, make print,.... etc. Some 13
prints later I had one you could lay on the counter and you would have a
hard time seeing it.
Believe me, this was not a scientific process. Try it sometime.
