hi all,
i hope i'm wording this properly.
what effects would be gained by using aperture priority? shutter priority?
thanks,
charlie

I think you need to re consider the question as there are/would be no "effects"

I assume you mean what is the difference

What JR1 posted! Perfect reference for this question.

I have never said why I just paste links

As many here will know I am dyslexic, and use a spell check, it is easier for me to "find" a link as a reply and post it than try to explain it myself, I am not being lazy.

Thanks

Why re-invent the wheel? Finding a professionally written & illustrated article is my preference as well.

I'm not an expert by no means, but I think a fast shutter speed relates to stopping a moving object, slow shutter showing motion as in a waterfall, or low light conditions w/tripod, while aperture controls depth of field and amount of light to match shutter speed to get correct exposure.

When I shoot all my action shots are shutter priority, I know some people will say proper photographer uses manual, did that for 30 years, why buy a good modern camera and shoot sports in manual, it is faster with calculations than I am

I have actually started leaving my camera sat in either P or the beginners A+ . So if I do need to grab and shoot, or the girlfriend wants to use it, I know it is going to produce a reasonable result with little thought. Actually set my C3 function (the last on the dial) to a high frame rate Auto ISO,
As JR says...why by a device with lots of auto functionality, and then use it totally in manual

I couldn't agree more, we can all "take control" when we need to but as you say when in A you know you are going to get a shot, whatever, without having to waste time on that grab shot

I never bothered with C functions until I got the D7000s now I have two set, nice little devices

I used aperture priority for many years with an 18-55 mm lens because I wanted to control depth of field: how much of my composition was in focus.

When I purchased a 55-250 mm, someone recommended using shutter priority because if your shutter speed is too slow for the lighting conditions or length of your lens, you end up with a blurry picture from camera movement.

In a nutshell:

use aperture priority if you want to control depth of field

use shutter priority if you want to stop action (fast shutter speed) of moving subject, or if you want to deliberately slow down or blur your subject (use a tripod).

Ok here it is. You have a exposure triangle of three settings that need to be made (on auto the camera makes them and with the icons the camera has a little more info on how to set them) They are ISO Shutter Speed and Aperture. You get to pick two of them and then the third Has to be a "set" setting to get the exposure you want. Many pick the ISO first using the lighting available as a guide. Low ISO if you have a lot of light and high if you don't. If you use the Priority settings on your camera you pick the shutter speed or the aperture and let the camera pick the other. The one you pick depends on what you want to do with your shot. If you pick aperture you will use a larger opening if you want to limit your depth of field like on a portrait where you want the subject sharp and the background a blur (Bokeh) or a small opening so that everything is sharp. If you pick the Shutter speed mode you will want to pick a fast shutter speed to stoop action like in a bike race or you may want to use a very slow shutter speed like of a waterfall and you want a foamy blur of the water and let the camera set the aperture. If you use M you will have to find the 3rd setting by using the meter in the camera (same one the camera will pick) or a hand meter or guess. I let the camera pick. Hope this makes some sense. Good luck. - Dave

I shoot mostly in aperture priority because it is quick and I watch my shutter speed.I feel that manual is the best bet for shots you really want to control.

Auto and all of the presets are of no use whatsoever.

I shoot RAW with min. JPG just for preview on Windows 7.

Obviously, you select speed or aperture priority based on what you're shooting. You can also adjust your ISO to make sure that you get the best of each.

Thanks for explaining yourself - although it wasn't really necessary. :D

As has been said so often on here if you really want to understand how all of this fits together get a copy of Bryan Peterson's book, "Understanding Exposure", as it is the best at explaining how it all goes together. Be sure to get the 3rd edition as the older ones are a bit dated.
