Basic DSLR Camera Modes Explained for Beginners

The letters on your camera can be confusing to you. What they do and how they can improve your own photos can feel like a mystery.
These letters you see are called the camera mode dial. Understanding the modes of the camera will help you learn about the exposures.

Before you start reading about the camera modes, I have created a list of common terminology and definitions in photography. Understanding and applying the terms listed below and how they can improve your photos and You will start to learn” about exposure; aperture, shutter speed and ISO and how it can help you with your photography. .

Words Related to the Camera Modes

Words with definitions for you to better understand the camera modes and their functions

Aperture ïn photography refers to the small hole in the lens that allows the light to enter the camera’s image sensor. As you take photos, you will begin to see how important just the right amount of light you need for the proper exposure.

F/numbers

  • It is referred to as the f/numbers. 1,2,3,4,5,6,7,8,9,10,11,..these numbers are known as f/stops.
  • These are represented as fractions; f/1.4 (a very large aperture, to let in as much light as possible), f/2.0 (lets in half as much light as f/1.4) through f/32.0 (the smallest standard aperture, lets in almost no light .

f-stops

  • The Lower f/stops give more exposure because they represent the larger aperture.
  • The higher f/stops give less exposure because they represent smaller apertures.
  • The Aperture affects the Depth of Field and the exposure in your images.

Depth of Field (DOF) is the distance between the closest and farthest from the subject in focus.

There are three camera settings that will affect the outcome of the depth of field:.

Aperture, focal length, and focal distance.

  • The smaller f-stop = larger aperture = narrower DOF
  • The larger f-stop = smaller aperture = deeper DOF

The video below does a very good job explaining depth of field.

please watch it!

Shallow Depth of Field refers to the narrow or smaller area in focus. You can accomplish this by lowering the f-stop The subject mattern stays in focus while the other areas usually it is the background, is blurred.

Seê example under the portrait mode) this , shows the people are in focus while the background is blurred.

Exposure in digital photography refers to the brightness or the darkness of the photo you have taken. It means how much light is taken in through the lens to the camera’s sensor.
Aperture, Shutter Speed and ISO work together to make the exposure of your photos.

There are two types of unwanted common exposure:

  • Overexposure, when this happens your photo, loses highlight detail and you will notice the bright parts of your, photo are washed out. If this has happened to you it is because when the light hits the sensor it is exposed to too much light.
  • Under exposure when this happens you will notice that your pictures look like you have lost shadow details and darker areas are looking like they are blackened. This is caused by not enough light going to the cameras sensor.

Focal Length in photography describes the lens and is the distance from the light entering the camera lens meeting at a point, called convergence point (or focal point) to your camera’s image sensor, when the subject matter is in focus and the lens is focused on infinity.

  • The smaller the number on the lens, the more scene you can see; wider angle of
  • The larger the number the less of the scene you can see; a narrower angle of view.
The diagram above shows the light source going into the lens and meeting at a convergence point. Then after meeting at point the of convergence the light source goes on to the sensor. The focal length of the lens is represented by the red dotted line.


Focal Distance is the distance between the camera and its subject. This is one of three different components, along with aperture and the focal length, these

three work together to create the depth of field.

ISO (International Organization for Standardization ) in digital photography means that ISO controls the sensitivity to light by digitally controlling the light it needs.

  • ISO is measured by numbers, the same numbers that were used to represent film speed in the older cameras. 400 Film speed back in the days of camera film is the same as 400 ISO is in today’s digital cameras.
  • The lower the ISO the more light the digital sensor needs. This why you use the lower ISO on brighter days and you don’t have to worry about using a flash
  • Compared to the low film speed back in the day.
  • When you are in manual mode and choose a lower ISO number, the cameras sensor (digital sensor) sensitivity to light is very low.
  • Unless you are looking for a specific look in your image, no additional light is needed.
  • Your image will appear more smooth and colorful.
  • You will see a little bit or no “digital noise” in your images.
  • Low ISO are numbers between <100 and 400 as listed on the ISO chart
  • Higher ISO numbers will increase the brightness of the image. This is one reason why you use the increased ISO at night.

Shutter Speed It is the amount of time the light is exposed to the camera’s digital sensor.

  • Shutter speed is measured in fractions of a second
    • For example, the shutter speed is 1/80 means that the shutter speed is one-eightieth of a second of the light exposure to the sensor.
  • A majority of the cameras can regulate up to 1/4000 seconds shutter speed, some cameras as quick as 1/8000 of a second.
  • In bulb mode, depending on the length of time the shutter button is pressed, the shutter speed can be up to 30 seconds.
  • Fast Shutter Speeds< 11000 per second
  • shorter exposure time to the cameras digital sensor
  • allows less light into the cameras digital sensor
  • everything is in focus
  • FREEZES the Action in wildlife, sports, and raindrops
  • Slow Shutter Speed is longer the exposure of light to the cameras digital sensor
  • allows more light into the cameras digital sensor

Now that we are finished with the terminology and definitions, we will start talking about the modes of at the camera

What is a Camera Mode?

The camera mode gives you the ability to choose how you want to take a photo. There are a variety of modes to choose from depending on the image you would like to capture.

Learning the camera modes is essential for you to grasp so that you may begin to comprehend how exposure works with the images.

Where do I find the Camera Mode Dial?

On top of most DSLR cameras is a round roary dial, called the camera mode dial. This dial allows the photographer to choose between manual or automatic modes on the camera. Depending on the DSLR camera you May be able to see it on your LCD screen

Automatic Program Modes

Starting out with the automatic mode is a good way to learn the exposure including; ISO, shutter speed and aperture.

By writing it down on paper after you take the photo, write down the ISO, aperture, and shutter speed, you will then learn to transfer it on to manual mode next time.

Both the new photographer and a seasoned photographer will appreciate the convenience of these programs.


Auto Mode – green rectangle or the word ”Auto”

Auto Mode is also called ”point and shoot” mode, is illustrated by a green rectangle or the word ”Auto” on the camera mode dial.

Japanese Oak Tree
  • Just like as it states, this mode is available
  • for snapping a photo at a minute’s notice
  • This mode configures the exposure which includes: aperture, shutter speed, ISO, and flash settings.
  • camera flash goes off depending on how much light passes through the lens to the cameras sensor .
  • Auto mode is a great camera mode for any photographer, whether a new or seasoned photographer, both of which will enjoy the ease of use.

Scene Modes

Most of the DSLRs (Digital Single Lens Reflex) cameras have four scene program modes:

There is a brief description of the different modes below:

Portrait Mode illustrated by a Sideview of a persons head.

!
Mother and Daughter

  • Best for taking images of people. .
  • This mode blurs the background by widening the Aperture while it tries to focus on the human face near you
  • The built-in flash is convenient when you photograph darker subjects. It may help in sunny situations
  • The Portrait Mode chooses a shallow depth of field

Landscape Mode illustrated by a mountain

“P
Sunrise,”..……………

Action/Sports Mode, illustrated by a person running

Squirrels playing tag
  • This mode increases ISO and has a faster shutter speed,
  • great for capturing wildlife, (including birds flying)
  • and Sports action.
  • The higher shutter speed freezers the frames to get a great image.

Macro Mode illustrated by a flower

Snow Crocus
  • This mode allows the photographer to capture an image closeup.
  • Macro Mode is commonly used for a closeup of insects or flowers.

Manual Modes

Manual modes allow the user to control more of the exposure (aperture, shutter speed, and ISO) of the image. Knowing how to use the manual modes helps the photographer capture an image of their creation.

Depending on the camera chosen the camera mode dial may read P, S, A, M or P, Tv, Av,M

Program Mode (P) The camera decides the aperture and shutter speed. The ISO is determined by the photographer either by choosing manual ISO or auto ISO.

Aperture Priority or Aperture Value (A or Av) allows you to control the aperture while the camera configures the shutter speed. The ISO is determined by the photographer either by manual ISO or auto ISO.

Shutter Priority or Time Value (S or Tv) allows the user to adjust the shutter speed and the configuration of apertures is automatically established by the camera. ISO is determined by the user who chooses either the auto or manual ISO.

Manual (M) allows the photographer to adjust the exposure triangle (shutter speed, aperture and ISO).

Summary

Whether you are a new to photography or a seasoned veteran, mastering all the camera modes will open your pictures up to new expressive images.

Camera Shake. What Is It and How Do I Prevent It?


As I sat gripping my camera waiting for the Cardinal to land. The rush I got from seeing the Cardinal made my hands shake. This had happened before. So it made me wonder, “how does the camera and lens prevent camera shake”. So I did some research.

Have you ever been so frustrated with yourself and your camera because your images are slightly blurred and you don’t remember shaking? I have felt like that, so I did more research on ”camera shake” and how to prevent it. Here is what I found.

While I was researching “camera shake,” I found that camera manufacturers have developed lens-based and in-body based image stabilization technology that may help with this.

What is Camera Shake?

So what is camera shake? After my research, I understand it to mean this, ”camera shake” is a phrase used in photography to define when the photographer accidentally shakes the camera while taking a picture due to unsteady hands, this can cause unwanted blurry images.

Before I jump into available camera technologies that may help you resolve the issue of camera shake, I would like to change your focus to blurry photos.

What are Three Types of Common Blurs?

I wrote a brief explanation of the three types of blurry photos.

Background Blur

Day Lily

Background Blur is a type of BOKEH, the most popular among photographers. BOKEH  (Bo-Kay) is derived from the Japanese word BOKE which means blur or haze and out of focus.

Blur does not have to be in the background to be BOKEH, the blur can be found anywhere on the image where you concentrate on your subject, while blurring the rest of the image.

This is created by the shallow depth of field, the more out of focus your background will be.

The topic of BOKEH is a little bit off scope for this blog post, but definitely worth reading further information on it.

Motion Blur

Motion Blur occurs when the cameras shutter stays open for long periods of time. During the period in which the shutter is open to the time it closes, this sensor will record all movement.

Movement that is recorded on the camera’s Sensor which will show as a blurred motion streaks or trails of light in your image, this is called the ”ghosting” effect.

I continue to work on my motion blur, I like to use the birds and wildlife in my backyard as my artist canvas.

Learning the concept of Motion Blur is hard, I am still learning. There is a lot of interesting information on Motion Blur, perhaps too much for this blog post.

Motion blur should not be confused with camera shake.

“Camera shake” is a phrase used in photography to define when the photographer accidentally shakes the camera while taking a picture due to unsteady hands, this can cause unwanted blurry images.

“Camera Shake” can happen to photographers without realizing it until he/she glimpses at the final image on the LCD screen.

You might be able to hold the camera very steady, but it is natural to involuntarily shake the camera. The length of time you are able to hold the camera or the shutter speed matches the Effective Focal Length determines the time you have before “camera shake“ happens.

Knowing the Effective Focal Length (EFL) of your lens should help you to avoid ”camera shake.” This means Focal Length (as marked on your lens) multiplied by the crop factor (sensor value) equals Effective Focal Length (see example below.)

100 mm x 1.6 (asp-c) =

EFL = 160mm

-> 1/160th shutter speed

The above answer represents the shutter speed at which ”camera shake” should not occur.

Three Ideas You Can Do To Prevent Camera Shake

  • To help with “camera shake” use a tripod. If you do not own one, it is worth the investment to buy one.

When I do not have my tripod near me and I want to capture a specific image, I will do one of the following:

  • If I am standing, I will hold my camera with both hands. Then, I’ll bend my elbows while raising the camera to my eyes. Next, squeezing my elbows together (resembling an upside-down tripod), focus on the subject in view, and finally, I will click the shutter button.

  • If I’m sitting, I will hold my camera with two hands and bent knees. I place my elbows on my knees then raise the camera to my eyes (in the form of a tripod.) I then focus on my subject in view and click on the shutter to create my final image.

Image Stabilization

Image stabilization is the way camera manufacturing help photographers create clear images. They add technology to camera lenses and camera body to help with ”camera shake.”

Optical Image Stabilizer

Optical Image Stabilizer is found only on camera lens. The Optical Image Stabilizer or also known by the abbreviation of OIS are manufactured right in the lens. This is a type of technology that exists in camera lenses to help with ”camera shake.” This technology helps with the motion of the camera and lens to produce sharper, clearer photos.

House Finches

Companies have different names for their own Optical Image Stabilization System (OIS).

Examples include are:

  • Nikon – VR – Vibration Reduction
  • Canon – IS – Image Stabilizer
  • Sony – OSS – Optical SteadyShot
  • Minolta – AS – Anti-Shake

Those companies listed above are only a few examples of camera manufactures that have technology that will help you with “camera shake,“ but does not help with Motion Blur.

Water Ripples

Optical Image Stabilizer technology by counteracting ”camera shake” to create a sharper image. The technology in the lens has two tiny gyros (short for gyroscope).

These tiny gyros works with the camera movements which send a signal to the lens element to move direction. This process illuminates “camera shake”.

Optical Image Stabilizer Lens, although they are costly, they are invaluable and worth the money.

In-Body Imagine Stabilization


In-Body Image Stabilization also known as I.B.I.S. and in-camera stabilizer has a type of technology in the camera body to help with ”camera shake”. This technology helps with the motion of the camera to produce sharper, clearer photos.

The technology that is used in I.B.I.S. is similar to the same technology used in lens-based lenses, except in this case it uses an actual cameras sensor.

The camera’s sensor rotates with the movement of the camera. It rotates with the help from the mechanism for the gyroscope.

In-Body Image Stabilizer works best with a shorter focal length lens. The longer focal length lens , a telephoto lens, the sensor has a tendency not move sufficiently enough to overcome the magnified ”camera shake.”
Fortunately, all lenses that are capable of sending the focal length and the focal distance lens will work with In-Body Image Stabilizer camera,

Including:

  • Older lens
  • Third-Party lens
  • Optical Image Stabilizer lens
  • Non-Optical Image Stabilizer lens

In-Body Image Stabilizer cameras are expensive, but you can use the above listed lenses and it is a one time expense. You will gain the advantage of Optical Image Stabilizer lens without having to buy multiple lenses.

Conclusion

My research into ”how does a camera and lens prevent camera shake” revealed a plethora of information and I certainly learned plenty.

Backyard Photography – Bird Personalities Captured

Baby bird : ”but mooooommm!” Momma Bird : ”…”

After my work week is over, I grab my camera and head to the backyard, more than ready to unwind. There is something about listening to the bird’s singing I find most relaxing and wholly comforting.

“Look at me!” Male bluebird seeking the attentions of a female
“What’s a guy gotta do!?”

”She sees me she sees me! Wait.. now what?”

As I watch and listen contentedly, I’ve learned that the singing and chirping of the birds, which brings me such peace, reflects the birds personalities. There are whole conversations I can be privy to if I am patient enough to pay attention. These can be a feisty child and their mom, as you saw previously, to a young man trying to find the right mate and getting ignored, or a gossipy bunch of ”hens in the hen house” or rather, birds in the bird bath.

What is Shutter Speed in Photography?

What is Shutter Speed?

There is a button on top of the camera called the ”shutter release.” By pressing the the button you are releasing the shutter to take the image..

Exposure time is your Shutter Speed. It is the amount of time the light is exposed to the camera’s digital sensor.

Learning how to use the different camera modes of shutter speed, aperture, and ISO, along with your patience, you can create your own beautiful images.


Shutter Speed Camera Modes

Cameras usually have three shutter speed modes to choose from: auto, shutter priority, and manual mode. (Description of the modes below)

  • Auto Mode (green rectangle) known as the ”point and shoot” mode. This mode configures the aperture and shutter speed. ISO is set to AUTO or MANUAL ISO.
  • Shutter Priority Mode (S or Tv) Photographer chooses
    shutter speed, camera configures aperture. User chooses AUTO or MANUAL ISO.
  • Manual Mode (M) Photographer controls the Aperture and Shutter Speed. User then chooses between the AUTO or MANUAL ISO.
Measuring Shutter Speed
  • Shutter speed is measured in fractions of a second
    • For example, the shutter speed is 1/80 means that the shutter speed is one-eightieth of a second of the light exposure to the sensor.
  • A majority of the cameras can regulate up to 1/4000 seconds shutter speed, some cameras as quick as 1/8000 of a second.
  • In bulb mode, depending on the length of time the shutter button is pressed, the shutter speed can be up to 30 seconds.

Below is an example of an LCD screen showing the shutter speed.

Fast Shutter Speeds vs Slow Shutter Speeds –
  • Fast Shutter Speeds
    • < 1\1000 per second
    • shorter exposure time to the cameras digital sensor
    • allows less light into the cameras digital sensor
    • everything is in focus
    • FREEZES the Action in wildlife, sports, and raindrops

  • Slow Shutter Speeds
    • longer the exposure of light to the cameras digital sensor
    • allows more light into the cameras digital sensor

Motion Blur
  • Motion Blur
    • Motion Blur occurs when the subject or subjects are moving and the photo is taken at a slow shutter speed.
    • When the subject or subjects move when the shutter button is opened.
    • Sometimes photographers intentionally use motion blur as a creative way of expressing their work.
    • Motion blur similarly gives the impression that the subject is moving.

Mind’s Eye View Photo

As I patientły wait for the bird to land on a specific branch, I remember the simple mantra, ”Mind’s eye view”

”Mind’s Eye” according to Merriam Webster, is defined as the mental faculty of conceiving imaginary scene. ”View” is to survey or examine mentally. Together, ”Mind’s Eye View” is an idea that through the mind’s eye we can create a beautiful visual and bring it to life through photography.

When you imagine visualize create you’re in a zone I call, ”Mind’s Eye View.”

Behind every photo of mine is an example of ”Minds Eye View” Photo.

Imagine, Visualize, Create

IMAGINE 

”to form a mental image”

Before I take a photo I imagine what the outcome if the photo will be.

VISUALIZE

”To form an image through the eye” 

I visualize the outcome of the picture

 CREATE 

”to bring something into existence” 

Finally, I capture the photo and create a mind’s eye view photo.

The the notion of ”Mind’s Eye View” Photo can easily be applied to any other active imagination.
