I see your 208 minutes director's cut and raise you the 309 minutes TV
miniseries.

I can remember, when I first read the book, written by Lothar Buchheim - it was
around 1980. The letters showed the green blue tint of Gilles image iirc.

By the way, the very first version of Gilles image was held in a dark blue green
tone...

A miniseries?! I didn't know. On German/European television, I assume?

So was it the same 208 minute movie with 101 minutes of commercials? :-P That's
probably what would happen here in the States, and it would then be advertised
as 'a miniseries', ha.

Thanks for posting this; I hadn't seen that series of image examples. The
various stages in the scene's development are fascinating. Yes, it's too bad
that some of the links to his even earlier experiments are broken. I'd love to
see his very first scene trial.

Curiously enough, the miniseries aired on BBC (with English subtitles)
even before hitting German TV.

Nope - 101 additional minutes of genuine content. Back in those days, we
didn't have any commercial breaks during TV shows anyway, and IIRC the
miniseries was first broadcast on the regional channels, which didn't
even have commercials between shows.

"Das Boot" had been partly funded by two of the German regional radio/TV
institutions, WDR and SDR, and from all I know production had been
geared toward two versions right from the start - the comparatively
short action-heavy cineastic version, and the elaborate 5-hour TV
miniseries attempting to capture the entire U-Boat experience.

I /think/ I heard tell that they even used a dual camera setup, one
camera for the TV shots and one for the cineastic shots. But I might be
confusing that with some other TV/cinema dual production.

After watching again the movie "Das Boot", I remembered your study and 
downloaded/rendered your's/Gille's scene. I am getting the shivers all 
over again...

Very well done by the way!

No doubt. I might have missed seeing this before.

The abyss.pov is a great scene to play with. I was trying changes to it July
2017 according to my render dates. I remember looking for underwater whale
pictures to see examples from reality. They were mostly bluish in color, from
lighter to darker... and very clear to my surprise! But I liked the green murky
water idea too, at first. My last render of it was with the blue color instead.
All done using P-R 3.7, which was another reason, to update the scene file.

I was also changing the mines to be of equal scale after realizing Gilles had
used artistic liberty to size and position those for the look he wanted, so I
never got around to remaking the nearby mines to be prominent in the picture.
And I wanted to get a water surface and seabed included, not completely
successful there.

Found a sunken ship photo at http://njscuba.net/z-gear/photo_s03190026.jpg
Maybe a good comparison to the blue abyss renders, except for haze/blur. Unlike
the whale photos you can find on the 'net that are incredibly clear.
I can't decide which way I prefer, although after seeing the photographs being
so blue that does have its merits. Maybe more menacing that way, with the idea
of the sub *clearing* those mines thus far.

Anyway... always loved Gilles artwork. Can't beat that.

I fully agree with you. Those whale pictures might be taken in very 
clear ocean waters: Pacific, Arctic/Antarctic. Other seas/oceans are 
more murky, like the North Sea. In Das Boot, the (Atlantic) Ocean is 
shown more like in Gille's scene.

Good point.
After looking at more info about some submarine depths (typically about 200
meters or 600 feet) and light transmission in oceans, the green color makes the
most sense if the location is near shore or shallow waters. Which is probably
where a mine field would be anyhow.
Funny that when I was younger I thought those submarine movies were usually
taking place near deep ocean bottoms, maybe 1000's of feet below the surface...
unless they were going up to use their periscope.

Was a while back when I saw a rerun of the very old TV show Sea Hunt and they
mentioned color change due to depth. Something about 'yellow becomes gray'.
Red end of the spectrum looses its colors, leaving green to blue, and going
deeper only blue is left.
Something about this was discussed many years ago about water renders in POV-Ray
and the blue color and depth, but I didn't remember that. What I said above is
from another look info found on the 'net. I'm not a diver.

Thanks!

Your post reminds me I said I'd look at new explicit bounded media 
attenuation control in a scene's SDL. I tried, but I don't think I 
followed up in that thread with details on my failures...
