Join Joseph "PhotoJoseph" Linaschke for an in-depth discussion in this video ISO (ASA), part of Photography 101.
- Earlier when I was talking about aperture versus…shutter speed, I said that there's a third part of the…exposure equation, and that's called ISO.…At the time, I said, let's forget about ISO for the moment,…it made it easier to understand aperture and shutter speed,…but now we need to understand what ISO is…and how it plays a part in this equation.…It's a little bit easier to think about ISO…if we go back to the days of film.…Back in the days of film, you'd buy film that was based…off of a certain number ISO or ASA,…you may have seen that as well.…ISO or ASA is essentially film sensitivity.…The lower the number, the lower the sensitivity.…
So, a number like 100, 200, or 400, were very common…ISO or ASA films.…Those are the kind of things you'd find in grocery stores.…If you went into a specialty store,…like a photography store, you'd find…ISOs that were lower, maybe 25 or 64,…and higher, 1600, 3200 and so on.…These were specialty films that were really designed…for specialty situations and professional photographers.…
