the stop ting?

a stop is a unit of light in photo terms I guess

if you take a shot at, say, 1/100th of a second @ F16 - then take another one at 1/50th @ F16, you've got 1 of light than the first

But if you did 1/100th @ F11, you'd also have 1 more stop of light

But if you did 1/100th @ F16 and upped the ISO from 100 to 200, then you'd have one more stop of light than the first shot.

When you get grads into the equation, a 2 stop grad will take away 2 units of light in the dark bit, but leave the clear unchanged.

It's really not that critical that you start doiing complex calcs though - we're digital now, so just take the shot, look at the histogram and see if you need to make any adjustments. I really do use 5 stops quite often, though mainly with water shots where I want bright reflectgions

think of light as water

turn a tap on a little

fill a cup

it takes ages

that's a small aperture (say F16) and a long shutter.

leave the tap running, now get a cup 1/2 the size and fill it

it's still F16, but it takes 1/2 as long to fill (1/2 the shutter speed). What you've done is upped the ISO here - high ISO needs less light just as a smaller cup needs less water.

empty the big cup

tuen the tap on so it's fast and fill it

it'll fill in no time

that's a wider aperture (f4 say) and a fast shutter.

now with the tap on at the same flow, only 1/2 fill the cup - it'll take 1/2 the time ok? That's under exposure.

empty the cup,and fill it, and leave it there so it over flows - that's over exposure...

this way of thinking bout it helps to visualise whats going on

you are so on my wave length..I can only think in pictures thats why I cant do dont know how much this has helped

Ade I cant thank you enough

you cannot imagine how much that has helped, I just done a years course on digital photography and could I get that number thing? No way..I have to use my ears, if it sounds right (the shutter speed that is) I know when it sounds right, so the stop thing is a real struggle.

think I might be able to get it now that I can visualise things

I will now have a better chance I think

been doing a little teaching lately and this apporach seems to work better than discussing light!

lights very abstract, with water, you get instant feedback - i.e. wet hands or and empty cup Wink

cool - it's well worth learning about isn't it? when the penny finally drops, it changes how see and meter every shot you take Wink
