"How it's made" on Discovery channel

[Robert Brummitt]

How many of you watch the Discovery channels program, "How it's made"? Don't hold me to the title but it's what I believe its called. For those of you who don't know what I'm writing about let me share. Each episode has about three to four segments on how how things are made. From cheese to Helicopters. One time they did lenses. It was pretty neat on how the glass is grounded and shaped, the testing and the assembly.
At the end of each episode. It's announced if you wish to know more or have a suggestion, please contact them. I thought it would be fun to do an portion on large format cameras. My question to you all is who? I posted this on Apug as well.

There's actually a nice video on how camera lenses are made

Wow, that's so cool.

Canon had some promotional material / "tour of the lens factory" videos up once, but half of it was just this suave announcer voice repeating the phrase "The Canon five-hundred millimeter eph-four ell eye-ess you-ess-emm!". This tour of the JML factory is much more interesting.

Thanks for the link Cyrus. I really enjoyed that.

There was a Lee Filter (filters and gels) segment a while back which had a sequence showing rectangular resins being hand dipped into a dye solution. Ever wonder why the horizon on your Lee or Singh Ray GND filter isn't perfectly...horizontal? Watch the "How It's Made" rerun and you'll see, "How It's Made" to be a few degrees off.

I always thought the Sing-Rays were poured not dipped. Does this ring a bell with anyone?

Love to see an Ebony being made!

You're right poco, some of the segments are rather silly. They designate roughly the same amount of time for, say, golf tees, as they do scissor lifts.

I have Singh Ray filters. When I saw the woman dipping the Lee grads I imagined that the same imprecise approach was behind the off-kilter horizon of my 3-stop hard Singh-Ray grad. I don't know how they make them at Singh Ray; I just know that the QC could be better. I returned my last filter, a 3-stop soft because the density was 2 1/3rd stops at the darkest margin.

At the prices Singh-Ray charges I'd return anything I wasn't 100% satisfied with.

OK, I have one person who says Ebony cameras. Any other makers?
I Think a segment on the wood field cameras would be very interesting. Every time, I go out to photograph, someone is bound to ask me what kind of camera, how old is it and if I made it. They always state of beautiful it is.
There is a bunch of craftsmanship that goes into a quality camera. If I get more info from you and catch the website of the show? I'm going to make the suggestion.
If enough of us do it then maybe they will!
