Aperture Priority

[mrblaine]

Why and when should you use it?

I use it when I want to keep the noise off of what I'm looking at.

I think Eriks brother did a great job on some shots in DC, focusing only on the driver and rig.

When I use the 100-400l lens or Micro in AP subject really stands out.

Off roading I have been trying to get my focal point on the driver when posssible AP works well for this. Setting up the camera where the focus drops off takes a bit of work...

i use it all the time. it gives the photos depth of field.
often times i like the whole pic to be clear... others i like the object to be clear and the back groud to be blurry.
here are a couple of examples:

That is nice Erik...but what about these dino bones>

I use aperture priority when I know what aperture I want (usually that?s wide open, for the narrowest depth of the field a particular lens allows) but have no time to do any manual adjustments and therefore rely on the camera to select shutter speed and ISO sensitivity automatically.

With D70 I find myself shooting in the ?P? mode most often, followed by the ?M? mode, then the ?S? mode, and I personally use the ?A? mode least often, not because I don?t like it, it just happens that way.

In the ?P?, Auto Multi Program, mode, I almost always adjust the relationship between the shutter speed and aperture using the main command dial (the spinning wheel the right hand thumb touches). If not for that, I?d be using aperture priority more often.

One more reason to use aperture priority is when you need to get the sharpest pictures possible and you know that a particular lens is sharpest at a particular aperture. Like, for example, the Nikon AF-S 12-24mm f/4 G is sharpest at around f/11. So, if you have plenty of available light, you can lock it at f/11, and shoot away. This method is most useful with fairly wide and fast lenses or for reproduction work.
