If i was to do a moon shot through trees (enough moon showing to focus on it ok) & used sunny 16 rule at say f/11 or f/16 & the trees were say 100 to 200 yards in front me...would the trees be in focus at this f stop ?

I have to ask as my intended site is an hour away & the opportunity only comes up once a month so i would like to be a bit prepared.

what you want to learn about here is hyperfocal distance, mate, which has nothing to do with properly exposing the moon ... which, you should expose for, btw, in this scene.... the trees will be sillhouetted, no problem there.

the narrower your aperture (larger number) the more that will be in focus from your focus point out towards infinity.... so, what you should try, is f/8 or f/11 on your sharpest glass, focus on the trees, and see what kind of sharpness (in-focus) you get on the moon... i'm thinking this'll be a tall order for any exposure, due to the distance between the trees and the moon, but what the heck, have a butcher's go at it, and share your results (don't forget to take some of the focus on the moon, too :deal

oh btw - google "hyperfocal distance" and you'll find plenty. you can also go to photo.net/learn and find some good stuff there. i'd find some links for you but i'm on dialup so it's a bit hard for me atm.

cheers mate

My guess (I said guess :D) would be yes but of course in silhouette

I had a look through david...do you recon that calculator takes into account the 20D's 1.6 crop ?

It sort of has a bet each way.

it might be worth trying to take one focussed on the trees and another focussed on moon and then stack them
