    pic was shot on 'p' mode.. iso was 800.. shutter was only like 1/12 since ISO was low & no flash I guess?


    The way I've been taking pics on P is to go with the lowest possible ISO but try and keep the shutter around 1/100 for hand shots.. is this a good practice?


    Is the pic grainy and kind of blurry b/c of the shutter?

    You can probably hand hold down to 1/60 or 1/80.

    To be honest, it sounds like you understand the basics of photography settings that you can move out of P mode and into AV/TV/M

    You'll have to pay more attention to what the settings change to at first, but once you get the settings right, minimal tweaks are needed.

    aperture, shutter mode

    you either set the desired aperture or shutter speed, in addition to the iso. If you shoot in AV, the camera calculates what shutter speed is needed for proper exposure based upon your ISO and aperture.

    in TV mode, you set the shutter speed and ISO. The camera decides what aperture is needed for proper exposure

    In the middle = proper exposure
    To the left = underexpose (too dark)
    To the right = overexpose (too bright)

    aperture: http://en.wikipedia.org/wiki/Aperture

    You use Av when the aperture setting is required, you use Tv when the time of the shutter is crucial.

    boring answer i know, but when you are aiming at a moving target you normally want to set the shutter speed, so you would use Tv.

    When shooting indoors you normally want the shutter as wide as possible so you would shoot in Av to control the aperture value and have the other settings adjust accordingly.

    etc etc

    It depends on the situation. I'll give a few examples.

    1. You want a panning shot of a race car. You'll want a slightly slower shutter speed so the background blurs but the car is in focus, so switch to shutter priority and set it a bit slower than you normally would, and the camera chooses an aperature setting for the right exposure. (Same principle for making flowing water look smoother.)

    2. You want to freeze a shot of a soccer player headbutting a ball. You'll want an extremely fast shutter speed, so pick what you want and your camera will choose a wider aperature for you for the correct exposure.

    3. You're taking a picture of a flower and want to have it in sharp focus but have a really blurry background. You'll want to open up your aperature to narrow the depth of field and your camera will choose the appropriate shutter speed for the exposure.

    4. You want a huge landscape photograph with everything in sharp focus. You'll want the smallest aperature possible, so you set it and your camera takes care of the shutter.

    If you really don't understand exposure or just want to learn more check out this thread I made a while ago.

    On the subject of Tv/Av... what do those letters literally stand for? Av at least starts with the same letter as aperture, but I have no idea where Tv comes from.

    Me neither. You must be a fellow Nikon shooter. =)

    It's my Canon p&s that has this Av/Tv lingo, and from what I've gathered, it seems to be a Canon thing. Canon must be using some sort of periodic table for photography.
