What is the ISO ISO?

[tirediron]

For some reasn my Googlefu is lacking today, and my remembery is NOT remembering... does anyone know what the actual ISO # is that references the standards for sensor sensitivity?

 

[Dave442]

Might this be the one?...
2240:2003:
Standardization primarily, but not exclusively in the field of still picture imaging - chemical and electronic -
ISO - Technical committees - ISO/TC 42 - Photography

it should be somewhere in the list under that title.

This looks like the one... ISO 12232:2006
ISO 12232:2006 - Photography -- Digital still cameras -- Determination of exposure index, ISO speed ratings, standard output sensitivity, and recommended exposure index

THANK-YOU!

Are you just trying to get points for the leaderboard? Had to wonder what you meant, wanting know the ISO for ISO...

 

[tirediron]

Doing a lecture on exposure, and I like to be able to explain that "ISO" in and of itself is nothing more than a standard, like ISO 9001...

Well heck, if that's all it takes then what is the ASA for ASA?????

Iron, if you can put the lecture off until after the elections President Obama might have a tele-prompter he can let go cheap.

I have a photographic memory for details like this... but the images keep coming out black. ;-)

Thats what happens when your developer gets old.

I've put some new stuff in the mail to you.

When did they start spelling ASA as "ISO"?

Yes there will be a test.

Native ISO is a completely different story. For MOST of you it's 100. Some of you it's 50. Mine's 25... for some odd reason. The other native ISO is probably referring to the sensitivity of the paint in aboriginal cave paintings.

 

[vintagesnaps]

Peeb, about the same time they stopped spelling it DIN.




OK, in the off chance you or anyone else may really want to know, DIN was the German abbreviation and is on some of my old cameras - don't ask me to remember what it stands for, it's in German! ASA was American (Standards Association) and ISO is International (Standards Organization).

I think there were other measures of light sensitivity too in early photography that eventually dropped out of use.

Okay, I have to mention something funny.

A while ago I was watching a photography "know how" video on YouTube just because I thought it was going to be interesting and sure enough, it was.

The guy would change the ISO and actually, yes, actually say International Standards Organization 400, 640, 800, etc. It cracked me up. Could you imagine talking to a photo buddy like that. "Yeah! I had to change my International Standards Organization to 6400 to take that shot!" Hahahaha
