Ahh, the Triangle thing.... How could such a simple mnemonic device create so much hate, discontent and gastrointestinal disorders among grown men! (Women are probably much more tolerant of such things)

The *did* change film to change ISO but provided that you could change film stock at a moments notice ... with interchangeable film holders for rollfilm and sheetfilm. I expect you knew that ? Therefor all three parameters were under users control.

Yeah, I knew that. But, but, changing film holders ain't the same as turning a dial to adjust brightness to compensate for an equivalent change in exposure. But you know that....

But even if ISO couldn't be changed easily Bryan Peterson did use the term triangle. And this is from his book.

They aren't very tolerant of that either!!!

I don't get your point and I don't understand your obsession with the triangle....

I have to quote User ID "the Triangle thing remains a mighty paragon of stoop piddity." but not the guy who invented he was smart to invent something he could sell.

The triangle leaves out the most important component of photography... LIGHT
It's really a pyramid, that inflates like a balloon, but don't tell anyone.

And you had to focus the camera by eye. It was such a toadally miserable scene. Really beats me why the OP ever got the hots for that 500C ... well, okay shes verrrry pretty. Awesome scandinavian industrial design. If you compare her to an RB, shes a goddess.

Why would he know or even think of the "triangle" when ISO was not a variable other than by film change?
Because you still had to take the film speed into consideration when figuring out the exposure.

I just wanted to point out that you may say Adams is good or bad but he definitely successful and he was very successful in his career as photographer without knowing the triangle. So I can conclude that the triangle is not needed for success but then.... the guy who invented the triangle was also very successful in selling books.
While Adams may not have called it a triangle, but he certainly knew the relationship between aperture, shutter speed and film speed.

I think the point is that the light isn’t a setting. The light is the light. Whether you call it a triangle or not the light is what those settings are based on.

They had dials to set for the various ASA speeds (now called ISO) of the different films, apertures and the shutter speed for the internal exposure meter.
Most of those exposure meters, you turned a control on the camera and watched an internal needle until it hit the mark for correct exposure. For really precise exposure you used a much more advanced external exposure meter. I had two or three meters and 3 or 4 film bodies and lenses. The bodies were SLR (Miranda and Olympus), one Range Finder and one TLR. I also owned a medium format Bronica and a variety of flashes etc. that would work with those bodies.
SLR=Single Lens Reflex, TLR=Twin Lens Reflex

As a professional photographer I operated my own darkroom for over 40 years.
I am very happy to say I no longer would go near film, developing tanks, or darkroom now that I use Photoshop I can do a 1000 times more in a fraction of the time and in far safer conditions.
If Ansel were alive today he would be a leading candidate for Post Processing.
