Aperture sizes

[munchycarrot]

I know some people do find this sooooo confusing. I had one of these on my fridge for a few months

Good idea Stef, but i reckon i would still get confussed:banghead:

[munchycarrot]

just think of the light Kim lol

[bryan]

very useful, :top:

Ok i'm thinking:confuse::D

That's the best/simplest description of an annoyingly difficult system I'v seen, thanks Steff. got any more ? :top:

I found this a while ago and it really helped me to understand dof... which is basically controlled by your aperture settings...

Glad people found this useful, i shall have a look at others i've got Ron :top:

i drew a diagram recently for a friend to show the relationship between aperture and shutter speeds and noticed it also explained dof by chance as well, already got patent pendng on it, still jsut sketches but will post up a version for all soon

Still really don't get the f settings! Without getting technical the lower the f setting the brighter the picture? Seeing the diagram I think I'm right in what I am saying!:banghead:

[munchycarrot]

yes, the smaller the number the bigger the opening, lets in more light! :top:

[Chelle]

I think I might have the hang of it now! Going 2 print off your diagram and keep in my bag! I'm easily cofused and very forgetful! :top:

I can empathise with that Chelle:)

Simple yet effective. If it helps think of "f/" as fraction, so f/8 is bigger than f/22 if thought of as 1/8 & 1/22 (fractions).

Can't wait to see the DoF included in this thread :top:

Not Quite chelle
The Lower the F Number you use the faster the shutter speed can be to get the right exposure,
The Smaller the Number the Bigger the Hole so You get more light, The more light you have got the faster the shutter speed can be, The smaller the number and the bigger the hole also means that you will have less in focus in front of your focal piont and less in focus behind your focal piont. DOF

You related to Stanley Unwin then, Harold?;)

So if you don't want strangers in the background or even the foreground to be in focus , you chose a smaller number (big aperture) and then choose a fast shutter speed, faster still if it's a bright day. If you want the background as well as your subject in focus, you choose a bigger number (small aperture) but if it's a dull day you increase the sensitivity ISO. How am I doing ?

Now you're beginning to sound like a politician :confuse:

Sounds as if you are doing just fine, Ron.
