April Challenge - Speed - ASA or ISO?

Another senior moment today, with speed I could only think in terms of driving and roads, but the places I drive are not the places to stop to take photos of traffic.

So my friends at dictionary.com came up with the answer.

Cameras have 3 speed adjustments - ISO (or the film you put in it), shutter and lens aperture.

So my photographic shot for speed is of one of my collection of old cameras. This is my Minolta X700 - it is manual focus, but does have through the lens metering, and a single program mode. Here you see the film speed setting (that had to be set manually) which was combined with the exposure compensation knob - +/- 2 stops in 1/2 stop increments.
