Hey.

I'm photographer David Bergman

and this is Two Minute Tips for

AdoramaTV

Today I've got a tip on how to make

aperture priority mode more useful.

You probably know that I'm a big proponent

of shooting in full manual exposure mode.

It gives you total control over your

images and doesn't leave anything to

chance in the camera, however there are

times when you might want the cameras

help just a little bit... for example, in a

fast-moving situation where you're going

in and out of extremely different

lighting you could ask the camera to

make some quick exposure decisions for

you.

In that case aperture priority is

usually the way to go.

It's represent as an A or AV on your camera.

Controlling your aperture allows you to

decide how wide or narrow you want your

depth of field to be. But anytime you

give your camera control of your

exposure there are consequences.

Let's say you're shooting outdoors you have

your ISO low to keep image quality high.

The camera will pick a pretty fast

shutter speed, because there's plenty of

light, but once you step inside unless

you remember to manually adjust your ISO,

your shutter speed could be too slow and

you'll have blurry photos.

Nobody wants that!

The answer for this problem is a

feature called auto ISO. Most modern

cameras have it, the beauty of auto ISO

is that you can set the maximum ISO and

minimum shutter speed the camera is

allowed to use, so maybe you set your

max ISO at 8000 or whatever you think the

highest usable amount is for your

particular camera, and your minimum

shutter speed at let's say 250th of a

second. Now when you go inside on

aperture priority the camera will still

lower your shutter speed for the darker

situation first, but only until it gets

to that set 250th of a second.

If it still needs more light it'll start to

raise your ISO at that point, it's the

best of both worlds. At the end of the

day I still recommend shooting on manual

but if you don't want to think and have

to move fast you can use aperture

priority to let your camera help you out

a little bit, but remember to use auto

ISO so your camera doesn't get totally

out of control
