Exposure Guide - Perfect for Noobs

[treegle]

It may seem a little presumptuous on my part to think that others just starting out in the world of photography have struggled to take in all the advice/guidance on the basics of exposure, but the following link provided me with a 'ooooh, I get it' moment.

It may not have the same affect for others as it did for me, but I'd thoroughly recommend this to novices who are trying to get to grips with exposure (the bucket analogy will probably stick with me forever now).

Yes, very good link

The bucket of water analogy is a common one, but that's particularly well written and clear.

Great link!

last lines not right in the first paragraph is it?

...a really narrow bucket can be used as long as you plan on getting by with less water.


Shouldn't that say a really narrow bucket can be used as long as the rain is heavy enough to give you enough water for a good exposure.

Not really, but that example only works if you a) have some rain (light) and b) it's falling at a constant rate.

Correct exposure is when the bucket is filled to a certain level, let's say to the top. In which case, shutter speed is how long the bucket is left in the rain, aperture is the diameter of the rim, ISO is the capacity of the bucket, and rate of rain fall is the light level.

His example is not constant though ....he starts by saying the rain is uncontrollable, like a bright or dull day you never know what bucket size (iso) and which aperture (rim diameter) to use until the moment.

He saying you can raise your ISO by using a smaller bucket same size rim diameter, or lower your ISO by using a large bucket same sze rim. But this means a really narrow bucket will need either, lots of heavy rain to fill it quickly, or very high ISO (small bucket to be filled) to get a correct exposure.

.. its not wrong that last sentence, just a little counter-intuitive an ending to a cool paragraph i though, like it reads to me the author was saying 'its ok as long as you plan to underexpose'.


just the way it reads to us maybe.
