Understanding Autofocus Modes in Digital Camera

Photo Tip Friday March 13

The Auto Focus modes in Digital cameras can be very confusing, and some photographers do not want to spend any time in understanding pros and cons of each mode. In this article I am going to cover one of the basic, yet important modes.

Did you know that your camera has different Auto focus modes?

Do you know how to get the best result by selecting a correct auto focus mode?

Almost all new digital cameras have very sophisticated autofocus system, but you don’t need to know all the technical specification to benefit this advanced technology. All you need to know is how to select the best autofocus mode for your application.

Choosing correct autofocus mode is very important and unfortunately many photographers do not pay enough attention to autofocus modes and its potentials in their photography. That is why I added Selecting correct Autofocus Mode as part of our new Digital Camera Bootcamp and I dedicated a full 30 minutes of classroom session to this topic (with lots of practical hands on in our field trips). In this article I write about the three major autofocus modes which almost all digital cameras are equipped with.

Last week I introduced the Auto-Auto Focus and Single Auto Focus. Here is a summary of last week article

Introduction to Digital Camera Auto focus Modes 

These three modes are presented in all digital camera from an entry level all the way to pro level cameras. By understanding the capability of each settings, your photography experience will be smoother and the result will improve more.

Auto Auto focus

This is the default setting of camera. In this mode you allow the camera to pick up the focusing points. When you select Auto Autofocus, camera selects the closest and brighter part of the scene or the closest face to focus on which may not be exactly the point that you want to focus on.

Single Auto focus

You select the focusing point and force the camera to focus on that point. It is advised to use this mode and lock the focusing by pressing the shutter button half way down and then recompose. If you use spot metering the camera will read the exposure from where the focusing point is. Make sure to lock the exposure as well if you shoot the spot metering. This Autofocusing mode is for still subjects.

Now let’s dig a little dipper in to Auto Focus modes by looking into Continuos or AI and AI Servo modes:

Continuos Auto focus 

In Auto Focus Continuos, you can lock the focus to your moving subjects

If you have a moving subject and want to keep subject in focus, you should use continuos autofocus mode. For instance you want to take photos of your pet running around in the park. New digital cameras senses the movement and predicts the direction of movement, then keeps focusing on your subject. The Continuos Autofocusing mode is suggested for moving subject. You press the shutter button half way down to activate the autofocus and keep pressing it down, when your subject starts to move camera will change the focusing to keep the subject in focus.

(most cameras are equipped with a back autofocus button. To get the best result it is suggested to use this button and use this button to activate autofocus and keep camera focusing on your subject)

Five Photography Tips

Digital Photography Tips

Five simple photography tips to improve your pictures

Photo Tip Friday August 29, 2014

Digital cameras are tools and like other types of tools they help us do a job faster and better. In fact digital cameras do not take pictures, they just capture what photographers tell them to capture! Understanding the settings and capability of your camera is the most important thing for taking better photos.

In this short article I am going to share five simple photography tips with you which will help you take better pictures regardless of what type of camera you use.

Tip number 1

Avoid meter pitfalls with highlight and shadows:

What does this mean and why is it important? It refers to a limitation, which all cameras have, to see both highlight and shadows at the same time. In photography terms we call this Dynamic Range. Our eyes can see many more highlight and shadows than a camera. Not allowing for this limitation is probably one of the most common mistakes I have seen photographers make.

Here is an example of a scene with strong highlight and shadows:

 

Strong highlight can affect your exposure. Select different metering mode

One solution to solve this problem is to change the metering mode of the camera to spot metering and your exposures will be much more accurate.

 

In this photo I selected Spot Metering for correct exposure

In our Digital Photography workshop for beginners we cover the metering system of digital cameras in full detail.

 

Tip number 2

Smart use of Built in Flash

I don’t use my camera’s built in flash as my main source of light, but I do use the built in flash as fill light. In Digital Camera flash photography class you’ll learn how to use your camera’s built in flash to improve the image quality.

Tip number 3

Understand the Auto focus system

Choosing correct autofocus mode is very important and unfortunately many photographers do not pay enough attention to autofocus modes and its potential in their photography. This is why I added Selecting Correct Autofocus Mode as part of our new Digital Camera Bootcamp and I dedicated a 30 minute classroom session to this topic (with lots of practical hands-on in our field trips). I always use Single Auto focus point to force the camera to focus on my selected area. Set your camera to Single Auto Focus point and you will notice how much faster you can focus and compose your pictures.

Tip number 4

Creative Flash Photography

Flash photography can be very creative when you learn the techniques. There are several settings for your flash: Slow Shutter sync, HSS or High Speed Sync, and RPT or Repeated Mode are a few of them. In our Flash photography class you will learn the most popular and creative techniques with simple and easy to follow instructions.

In this picture I used First Curtain Slow Shutter sync and set the shutter speed to 1 second. After pressing the shutter, the flash fired and then I rotated the camera for this amazing effect.

Tip number 5

Avoid tight composition

Always compose your photos a little looser. This technique allows you to correct the image later in post processing. In our Photoshop techniques class or Lightroom workshop you learn all the important tools for better and faster post processing.

Here’s an example where I loosely composed an image.

 

Don't compose too tight to your subject. Always make some room for post processing

Now I can crop it to any aspect ratio I want without cutting out the main subject.

Auto Focus problem?

Understanding your camera’s Auto Focus system

Is there something wrong with my camera auto focus system?

Photo Tip Friday May 9, 2014

Have you ever wondered why your camera doesn’t always focus on your subject? Or thought there was something wrong with the Auto Focus function of your camera?

In this article we are going to look at Auto Focus features for new digital cameras. There are several options available for Auto Focus and we cover most of them in our Digital Photography Bootcamp classes but for this article I am going to discuss two different settings which can affect your camera’s auto focus performance.

In single Auto Focus mode you can select the focusing point

Auto Focus Auto or Auto Focus Single

By default almost all digital cameras are set to Auto Focus Auto.  What this means is your camera “sees” the scene and compares it to its memory bank (not the memory card, but the information manufacturers add to camera processors) and makes a decision on where to focus. That doesn’t seem good, does it? So why do manufacturers set Auto Focus Auto as the default setting? Because they think their cameras are more intelligent than we are!

In Auto Focus Auto your camera may select any of these focusing points.

How does Auto Focus Auto work?

In this mode the camera has a wide focusing area and searches for items inside that area to find a main subject. Manufacturers make different data available to enable a camera to recognize possible main subjects; some examples are Face recognition, Contrast priority, Brightness priority, Distance, etc. It will select one object in the scene as the main subject for focusing; usually it’s the closest, most contrasty and brightest item. If you want to take a photo of your child in a park and there is no one else in the scene, the camera will do a decent job. What if there are other children in the scene and your child is furthest away from the camera? Here comes room for focusing error: your camera does not know your child, so it focuses on the nearest kid with a brighter T-shirt!

What is Auto Focus Single?

Auto Focus Single is the setting I recommend in our photography classes because I believe that even the most expensive camera does not have the talent that the human eye and brain has. In Auto focus Single, your camera still focuses automatically but you control where it should focus. Auto focus single allows your camera to focus faster (it’s not searching for data) and more accurately (it’s using your choice of subject).

How does Auto Focus Single work?

It is very simple. You select the focusing point and your camera will focus on this point regardless of brightness, contrast, or even face recognition system. So you are in full control!
