Is f2.8 larger or is f/22 larger

[APPRo]

My friend and I are having a friendly debate about aperture.

He insists that f/22 is larger than f/2.8 and I disagree, because it's measured as 1/22 and 1/2.8.

1/2.8 is a larger number than 1/22 isn't it?

2.8 is more open.

[Bugs81]

1/2.8 is a larger number than 1/22 isn't it?

Correct.

[Craig G]

2.8 is a larger opening than a 22.
Smaller the opening the larger the aperture

f/22 is a larger number than f/2.8. F/2.8 is a larger hole than f/22.

[Pugs]

f/2.8 is a larger number 1/2.8 or a little over a half versus f/22 which is considerable LESS than a half...

f/2.8 is larger aperture opening than f/22.

f/22 is a larger (deeper) depth of field than f/2.8.

pugs nailed that one!

Thanks Pugs,

That settles that for now

Yepp Ten,

I discovered a simular article yesterday on this very topic, and once I seen it visually, I got it. Visual really helped.

Next question pertaing to open aperture = great landscape and portraits.
Correct

How does shutter speed now play into this.

I beleive a fast shutter speed is for action, and a slow one for night shots, landscapes and portraits

Correct

That's it???

Come on guys!.. we need a few more of you to repeat the same answer.
I am kind of disappointed with your lack of willingness to help the OP...

more open is going to be good for portraits because it blurs the background...for landscapes you want to have a deeper depth of field so you want a smaller (bigger number) aperture.


as for shutter speed yes for action you need it to be fast. for night shots its going to need to be slow. For landscape I guess it depends...you could go either way...and for portraits, unless you are shooting with a tripod and your subject is going to stay very still...I would not go with a slow shutter speed.

Of course I am pretty much a beginner myself so if anybody wants to correct me go right ahead!
