Looking for chart that shows f-stop vs. shutter-speed

Jen Lambert , Apr 19, 2007; 09:51 a.m.

A few years back on PN, someone posted a matrix-style chart that showed the relationship between f-stop and shutter speed. It was color coded so that you could find a certain exposure and follow the diagnol line of that color to a different f-stop or shutter speed that would give the same exposure.

I need this for training a few people at our studio and I've searched for it high and low online and have found nothing. I'm not looking for the exposure value (EV) charts... just the f-stop/shutter speed chart. Thanks if you can help!

Surely it wouldnt be too hard to create one in a couple of minutes...

Equivalent f-stop and shutter speeds

You are so generous Craig. Methinks some people are trying to make the relationship more complex than it is.

This is slightly more comprehensive:

Where is F/1? :)

Where is F/1? :)

Mark, that's certainly got to be the most comprehensive and confusing info I've ever seen on the issue.

I remember having a guy who just graduated from 4 years of photography at college who was on a co-op with me for 2 weeks. That's the kind of stuff he had to memorize. The problem was that when we were on a wedding and I asked him for a light reading, he couldn't get it right. In 5 minutes I taught him the essentials and how to do synchro-sun, something even the prof couldn't do easily. KISS - (Keep it simple stupid) in case someone thinks I'm wierd, well maybe I am.

I don't understand the need for such a chart except while learning photography, and the chart should be in the text book or classroom.

To be able to take pictures in the field or studio, the photographer must understand this relationship at the most basic level. Otherwise how would you make choices about depth of field and exposure to control the appearance of the picture?

Charles- that's the whole point! The people I'm working with are just starting out and they are at the most basic level. They are assisting right now (in the sense of "hold the shim" or "I need a new battery") and want to learn, but this basic relationship is not sinking in just yet. I plan to go over the chart with them then take them outside and shoot with varying f-stops to illustrate the point.

Call me lazy, and I know making one would rather simple, but this one was rather well designed (I'm kind of weird about symmetry and things lining up in a document or chart, as it were) and I would sort of like to have it again. I grew attached to it... not for knowledge exactly... more as familiarity... I could accept another version, if it were pretty, too. :-}

Jen, sorry I misunderstood. When you said "new people at our studio" I somehow thought they would be trained photographers, not novices still in training. In that case this chart seems very concise and makes the relationship clear to me, but I know this stuff already.
