What Are Camera Autofocus Points?

Modern cameras are seeing a constant improvement in their autofocusing mechanisms by using a large amount of autofocus points, among some major technological advancement. If you’ve never used a camera with autofocus points, or don’t know how to use them properly, this article will help you a great deal.

A Brief Description

When you use your digital camera to take a photo, you must have seen a number of small boxes appear on the viewfinder or the screen. These are called autofocus points, and they are used to get the best possible focus for your shot.

While using automatic focusing on your camera, you can tell which part of your image the camera is focusing at by seeing which autofocus points are lighting up. This is a great way to be sure that your camera is focusing on the part of the image that you want it to focus at.

Manually Selecting AF Points

While autofocusing systems on modern cameras are being improved every day, they can’t be accurate all the time. This is why you should manually set the AF points on your camera if you want it to focus on a very specific part of the image. Most cameras these days allow you to manually select either one focus point or a cluster of them. Both these options are useful in certain situations. For example, if you are taking a portrait, then choosing one point and placing it on the subject’s eye is going to give you the best focus. Similarly, choosing a cluster could be helpful in taking a group photo of people standing in a certain part of your frame.

 

Whichever camera you own, always remember to use the correct kind of focusing system for any given situation. This will ensure that you never miss a great shot because your camera decided to act up a little while trying to get the focus.

How to Clean Sensor Dust

For any photographer, having specks of dust ruin otherwise perfect photos is very frustrating. Luckily, there’s a very easy way you can get rid of this sensor dust without spending a lot of money.

Use your Camera’s Auto Clean Feature

Many of today’s DSLR cameras have a function inside them that can vibrate the sensor slightly to shake off the dust. This doesn’t work most of the time if you have a lot of dust on your sensor, but for basic cleaning it should do the trick.

Use a Pressured Air Can

To clean small amounts of dust that have found their way onto your camera sensor, all you need to do is use a pressured air can to blow it out. To do this, simply pop off the lens from your camera body, insert the nozzle of the air can slightly into the opening, and blow the air onto the sensor. Most types of dust will just be blown out of the body.

One thing to remember is to keep the camera facing downwards so that when you blow air into it, the dust falls down rather than going farther up into the body.

So you see how easy it is to clean your camera’s sensor? All you need are a few minutes of your time and an air can to blow that dust out of your precious DSLR.

What are Camera Drive Modes?

If you use a DSLR, you must be familiar with the different drive modes that can be used to take a photo. Today, we are going to take a look at how these modes affect the way a camera takes a photo.

Single Shooting

By default, your camera’s drive mode is set to Single Shot. This means that when you press the shutter button, the camera takes one shot. If you want to take another image, you just press the button again. This works in most everyday situations, and many people won’t need to change to another mode most of the time.

Continuous Shooting

If you are an action photographer or just like to take backup photos so you can later choose the best one, you should set your drive mode to Continuous or Burst. This allows you to keep pressing the shutter button and your camera will keep taking photos until you release the shutter.

Delayed Shooting

The third type of drive mode is a Timer or Delayed Shooting option. This is useful when you want the camera to be still after pressing the shutter for a long exposure shot, or if you simply want to join in on the family picture after pressing the shutter.

Remote Shooting

For cameras with compatible remotes, you can use the Remote Shutter option to take a picture through the remote control. This also helps in avoiding any kind of movement or vibration that could be caused in the camera when you press the shutter. It also helps in taking wildlife shots, where you may not want to get too close to the animal and scare it.

 

So there are the basic drive mode options that you can find on your DSLR camera. The next time you’re taking a shot, be sure to select the right kind of drive mode for that particular situation.
