Couple Of Questions For My Trip Coming Up

Wed Jul 26, 2006 9:13 am

First, I have looked at some archived threads about shooting through aircraft windows. They all say to use a certain aperture that keeps the image in focus but removes most of the scratches and junk on windows. What is the ideal number to use when shooting through windows for
a. morning
b. afternoon
c. evening

Second, I will be leaving from SJC in the morning, around 8 am, and they have an observation deck. What aperture should I use there for highest quality.
Thanks

Simple.

You need to select an aperture that will support :
A) The shutter speed you want
B) The depth of field you want
C) The amount of light required for the ISO you want, taking into account both A + B.

Not necessarily in that order. And there is no 'rule' for which is best.

Now, me being pretty new to this all, what shutter speed DO I want? I would be using ISO 200 film.

it depends upon the light you have. Most times are Around 250th with a F7-9 aperature I belive but it all depends upon the light.
Lighten up while you still can, don't even try to understand, just find a place to make your stand and take it easy

Flamedude,

Jeff is 100% correct, trouble is his answer does not take into effect the fact that without knowing the relationship these factors have to each other you can't decide.
You need to learn about shutterspeed, aperture etc and how that affects your photography and there are some excellent books and some terrific websites that will assist.

There is not the space here to explain it all.. this photography thing takes some learning and is not an instant gratification activity.

Cheers

One that is slow enough to give you correct exposure on the basis of the available light and to give you the depth of field you need, but fast enough to avoid camera shake, taking into account the amount of zoom you are using.

I presume you realise that shutter speed and aperture are reciprocally related - as the shutter speed gets faster the aperture gets bigger and vice-versa.

I was looking at another thread that had a link to an exposure calculator. There, it says with ISO 200 film, at average morning light, I should use about about 1000 shutter speed with f8 aperture. Though Jetmatt777 says use 250 or around there. Which is the appropriate one?
Thanks
