What is a good website for research for how to use ISO, Aperture, and Shuttle Speed?

Question

I had d40 i wonder if there a site teach me how to shoot with what setting in certain condition, night, portrait, outdoor, landscape etc..

anyone can gave me some setting for aperture and shuttle for night shot.

Answer 1

Read and study the Owner's manual for your camera.

ISO is a measurement of the sensitivity to light of a light sensitive surface, whether film or sensor. The higher the ISO the more sensitive the surface.

Aperture (aka f-stop) is a measurement of the size of the opening in the diaphragm in the lens. It is an inverse relationship - f1.2 is a very large opening; f22 is very tiny. The f-stop determines how much light is admitted. The larger the opening the more light admitted.

Shutter speed controls the time light is allowed to expose the light-sensitive surface. It also affects whether motion is blurred or not. To "stop action" a fast shutter speed is needed.

The meter in our camera bases exposure on the ISO we set, the f-stop we set, the available light and suggests a shutter speed. If we're in full Manual Mode we can use the shutter speed suggested or set it differently.

All of these work together to make a correct exposure. Suppose we're shooting outdoors on a sunny day. We decide to use ISO 200. We're going to photograph horses running in a field. We decide that we want to stop the motion of the horses so we know we'll need a fast shutter speed.
(An old rule, known as the "Rule of f16" states: On a sunny day, set your f-stop to 16 and the shutter speed as a reciprocal of the ISO". So we'd use f16 at 1/250 second shutter speed, 1/250 being as close as we can get to 200).

Now suppose that is the exact setting our meter says will give correct exposure. But 1/250 sec. just isn't fast enough to really stop the horses in full gallop. We change the f-stop from f16 to f11 - and now our shutter speed is 1/500 sec. Still not fast enough. Now we open up to f8 and our shutter speed is 1/1000 sec. and we've stopped the galloping horses just like we wanted.

How and why is this possible? Because as we "open up" from f16 to f11 our lens admits twice as much light. For a correct exposure our shutter speed increases since with twice as much light our light-sensitive surface only needs 1/2 as much exposure to light and that requires a shutter speed twice as fast and 1/500 sec. is twice as fast as 1/250 sec. If we "open up" another stop to f8 then, again, twice as much light is admitted as at f11. Our shutter speed doubles again, to 1/1000 sec.

IMO, you should try shooting in Aperture Preferred Mode (you set an f-stop, the camera selects a shutter speed) as the first step in understanding the relationships. Then switch to Shutter Preferred Mode (you select a shutter speed, the camera selects an aperture). I shoot in Aperture Preferred about 95% of the time.

If you want to shoot the nightime city skylight you will need:

1) A tripod
2) Your camera in Manual Mode
3) The shutter at "B" or "T" (either of these allow you to keep the shutter open as long as you want)
4) A cable release
5) Lens of your choice

If you use ISO 100, here are the settings:

f5.6 @ 15 seconds
f8 @ 30 seconds
f11 @ 60 seconds

If you use ISO 200:

f5.6 @ 8 seconds
f8 @ 15 seconds
f11 @ 30 seconds

An excellent book, IMO, is "Object & Image: An Introduction To Photography, Third Edition" by George M. Craven.

Answer 2

ISO two hundred is the pleasant to make use of at any time when you'll. Leave it at two hundred, do not alter it except it will get too darkish. F8 is approximately the pleasant aperture for usual capturing. Use wider in the event you desire much less intensity of subject, use extra in the event you desire extra DoF. Shutter velocity is dependent upon lights. Full solar, ISO two hundred F8, shutter velocity could be a million/800 of a moment. Shoot an A, aperture precedence, and examine that the shutter velocity is just about a million/800 for the period of daylight hours. Once you get that down, begin utilizing guide publicity.

www.betterphoto.com

This is a really great photography website with an open forum for questions. They have equipment reviews, online courses, articles, and if you register you get a free gallery space. I highly recommend it.

Answer 4

If you need "shuttle" speeds, I'd look at www.nasa.gov
