  • Every photographer has had to deal with blurry pictures.

  • The important part is that you understand why your pictures are blurry

  • so you can fix them.

  • So today Tony and I are going to talk about eight reasons that your photos are

  • blurry and how to fix them.

  • The first problem

  • is that your pictures are blurry all over with a bit of motion

  • to them.

  • Your problem is probably camera shake. To fix camera shake, one thing you should

  • understand is the reciprocal rule.

  • That's just a fancy shmancy way of saying that your shutter speed should be

  • greater than your focal length. So if you're shooting at 50 millimeters, for

  • example, your shutter speed should be 1/50th or greater. An easy way to deal

  • with this is to switch your camera to shutter priority mode.

  • Make sure that your shutter speed is your focal length or greater and then

  • put your camera into auto ISO mode and that should eliminate camera shake.

  • Another way to eliminate camera shake is to use image stabilization or you can

  • work on your your technique with holding the camera. You can prop your arms up

  • against your body and that will help eliminate camera shake.

  • Or you could use a tripod. If you're still having problems with camera shake

  • and you're in a situation where you just can't fail,

  • maybe you're taking pictures of your kids blowing out their birthday candles.

  • You can just put your camera to auto mode and that should take care of it for

  • you.

  • The second most common problem is motion blur. With motion blur your subject isn't

  • holding completely still and you kind of see their movement in the picture.

  • As you can see still parts of the picture sharp but the subject itself is

  • blurry.

  • This is really easy to fix. Just put your camera into shutter priority mode and

  • pick a shutter speed that's fast enough to freeze the motion. With people,

  • like this,

  • 1/60th is usually good. If they're playing sports, 1/250th or 1/500th. And

  • wildlife, you want to be at 1/1000th or 1/2000th. So i'll bump

  • this up to 1/250th because Chelsea was moving pretty fast and we'll take

  • another picture.

  • I'm a constant sport.

  • If your problem is that the part of your photo that you

  • focused on is in focus, but the rest of your photo including the background is

  • blurry, you probably just have a shallow depth of field.

  • That's an easy fix

  • you just need to raise your aperture number. So if you have a low f-stop

  • number like f/1.8, raise it to f/5.6 or something higher.

  • It's a common problem when people buy a new lens like a new 50 millimeter f/1.8,

  • because they're not used to working with shallow depth of field. It's one of the

  • benefits of those lenses, but it's also one of the challenges.

  • Another common problem is missed focus. Especially when you're using a lens with

  • shallow depth of field, cameras aren't perfect and they often miss focus.

  • let's take a look at what happens

  • To make sure you nail the focus every time, use a single small focus point. And if

  • you're shooting people,

  • place it on their closest eye. Also be sure to take lots of pictures and refocus,

  • because no camera gets focus perfect a hundred percent of the time.

  • So let's try that again.

  • Another way to solve it is to use a higher f-stop

  • number, just like you wanted to increase your depth of field.

  • Now let's talk about air quality. We'll have to head outside for this and it's

  • pretty cold,

  • so we're going to bundle up.

  • Alright, so this will be a good example of what we-

  • oh my gosh it's way too cold out here.

  • All right we're ready let's go.

  • Alright, so the farther your subject is from you the more haze and humidity and

  • all that other air garbage there is between you and your subject. Especially

  • if it's a hazy or foggy day, a subject that's far away it is going to appear slightly

  • out of focus or not sharp.

  • So I'll take a picture of Tony not too far away with this 50 millimeter lens

  • to show you how it looks.

  • So it looks nice and clear, he's not so far away.

  • So Tony is going to move far away and I'm going to keep him the same size in

  • the frame, but use

  • ah, this monster. Ok, so now Tony is the same size in the frame but very far away

  • so let's see what happens.

  • What about light quality? That could be your problem.

  • The softer the light, the softer your picture. If you have hard light your picture will

  • be sharper but you probably won't want that for a portrait.

  • It is good for wildlife pictures, though. One more thing that can cause problems

  • is focusing systems that are misaligned just a little bit.

  • people often blame their focusing problems on the camera, but it's very

  • rarely the problem. If you check chapter 5 in Stunning Digital Photography, we

  • walk you through the entire process of troubleshooting. And I know what you're

  • thinking, this video is great how do I learn more from you two?

  • We wrote a whole book, 9 hours of video plus a community that will help you out

  • with problems like these.
