Table for Aperture / Shutter speed / ISO

As a newbie to Photography, is there a good table out there for trainee photographers to get a good understanding of aperture, shutter speed and ISO under different light conditions :)

The sunny 16 "rule" for a guide.
http://en.wikipedia.org/wiki/Sunny_16_rule
But not really, a table will not know what you want your depth of field to be or what you want your shutter speed to be.
The best advice I can give is learn how they relate to each other, learn what one F/stop means in changing each of them.
A one F/stop change one way or the other means a doubling or halving of light.
So assuming all other settings remain the same F/8 will let through half as much light as F/5.6.
The same as 1/100th will let through half as much light as 1/50th sec.
And ISO 100 will register half as much light as ISO 200.
If you want to register the same amount of light in a pic and you change the aperture from F/5.6 to F/8 (half as much light) to get a larger depth of field- you will have to change either the ISO or shutter speed by the same amount (one F/stop) the other way.
Eg- shutter from 1/100th to 1/50th sec (twice as much light) but may be bringing in movement blur.
It's a juggling act but a pretty simple one.

I would recommend you get Bryan Peterson' book 'Under Standing Exposure' plain easy to read language. I think it has a chart in it, I'm not sure but just google it and there are lots of them.
Welcome to UHH. You are among friends. We have newbies ot photography, like me and people that really know what they're talking about like Lighthouse and a couple of others. Just jump in :thumbup: :thumbup:

I know the chart you are asking for. Have seen it many times but can't remember where. I Googled "exposure triangle" and got more hits than you couldd ever read. If you do this you will get your answer. I too recommend you pickup a copy of Understanding Exposure. The chart isn't there but if you read this book you won't need a chart because he simply demistifies the whole business of the triangle. Happy shooting.

Here is a page and site i like to recommend. I like the simplicity of it.

I agree with tramsey and Db7423 about getting the book Understanding exposure---even if you find the chart you are looking for.

:thumbup: You have received some good answers here.
For simplicity - just remember;
1> Larger aperture number - e.g f22 lets in less light than a smaller aperture number e.g f16
2> The faster the shutter speed the less light enters the camera.
3> The difference between stops e.g f22 to f16 is double the amount of light so if f22 was the right aperture at 1/60 shutter speed - then f16 would require 1/125 for same exposure.
4> Larger ISO number means more sensitivity to light - but with the disadvantage of less quality due to noise. Therefore it is best to try to keep to a lower number such as ISO 100 unless you need to gather more light.
As an example - f22 at 1/60 at ISO100 is the same exposure as f22 at 1/125 at ISO200.

Set your ISO. (based on available light) Set your f/stop. (based on Depth of Field desired). Then pay close attention to your histogram. 'expose to the right'. Make sure the right edge is almost touching the right edge, without going outside it.
You can do all this without a chart, and should find your image is well exposed.

The old fashioned Western Light Meter did this automatically. I found mine recently when looking for something else and happened to notice how well it did this very thing even 46 years later
