Photography Definitions - the Letter A


Photo showing chromatic aberrationsChromatic Aberration

An aberration is an imperfection in an image caused by defects within a lens.

These defects can affect color, sharpness and shape, on parts or all of the photograph.

Chromatic aberrations are shown in this high contrasty scene of branches against a white sky.

Look at the magenta colored fringing on the left side of the branches and the green fringing on the right side of the branches. 


Ambient light is also known as existing light. It's the light that is already there before you add any light with your camera's flash. The natural light in a particular scene, such as daylight or lighting from a man-made source such as a lamp or floodlight that is already turned on.


This photo term is used to describe how much a lens "sees." A large angle of view means it's wide angle and your picture will include a lot more subject.

Diagram showing 3 different angle of views.Blue shows a normal angle of view. The green area shows more of a telephoto lens setting
angle of view, and the red area shows a very narrow angle of view from a super telephoto lens.

 A small angle of view means it's zoomed in to a narrower angle or telephoto and not as much of the scene in front of you is included in the photo.


The definition of aperture is the size of the opening inside the lens. It controls how much light strikes the camera's senor sensor. The numbers used are called f-stops.

A lower number such as f-2 or f-4 means the aperture of the lens is open more or larger. More on the definition of aperture.

Diagram to go with the photography definition of aperture

Changing the aperture will change the range of how much of your scene is in sharp focus. A large f-stop like f-11 is a small aperture and will give you more depth of field. A larger depth of field is a larger range of near to far things that are in focus in your photo.

To understand how changing the aperture can effect your photo exposure exposure, read this: Photo Exposure.


A camera setting where you set the aperture (the f/stop number) and the camera will set the shutter speed automatically to give you the right exposure.

Popular with portrait shooters and landscape photographers who want control over the range of things that are in focus, the depth of field. Here's more on modes and camera settings.


As a photography term, it mean any light on your subject that is not the sun or something illuminated by sunlight. Artificial light can be added to the existing natural light on purpose, as is with fill light.

This could be your camera's flash, a light bulb or other electrically generated light source.


The proportions or ratio of a picture's width to it's height.

An 8x10 print has the same aspect ratio as a 16x20 print. The width compared to the height in both sizes are 4:5 ratio.


Picture imperfections from an error when the camera processes the data or from a bad spot on your camera sensor. Sometimes it's only a single tiny pixel that won't be seen. Sometimes there can be hundreds or thousands of bad pixels, showing up in what's called  aliasing or moiré patterns.

Digital camera technology has advanced so much recently that it's unlikely you'll ever have to worry about artifacts although shooting at very high ISO settings can sometimes give your photo artifacts too.

A great option, one that I foolishly didn't use until recently and now I love it. With this camera setting you can manually set the aperture and the shutter speed and your camera will choose the right ISO for the right exposure.

Here is a post on why you really should be setting your ISO on AUTO.

Digital Photography Definitions and Terminology Beginning With "B"


Making copies (and saving in a 2nd location) of important computer files such as documents or your precious digital photographs. This protects you if the original files are lost or damaged.


Photo term used to describe the situation when most of the light is coming from behind your subject. You are shooting towards the light, so your subject is lit from behind. A silhouette of a person with the bright sun setting behind them is an easy example to imagine.


 It's simply a copy of your original photos to another location to prevent loss.  You are taking a risk of losing your images if you don't have a backup system of some kind. Here is an article titled: Best Photo Backup System.


Aperture definition - ball head photo

Tripod ball heads are extremely popular on monopods and tripods.

They are easy to loosen to adjust your camera on any of its axis.

Here is a comparison between camera ball heads and pan-tilt heads: Tripod Ball Heads.


A battery grip attaches to the bottom of a DSLR and carries two batteries to give you more shooting power.  These grips usually have several camera controls to make shooting in a vertical "portrait" mode much easier.  Here is more on the definition of a battery grip.


Benro isn't a photography definition. Benro is a relatively new player on the long list of camera equipment manufactures.

A good part of this website covers many of the popular digital camera accessories that you can have fun with. Here is some information on Benro Monopods and Benro Tripods.


Bokeh means blur, but specifically it's an effect based on getting different shapes in the out of focus areas of a photograph.

Lenses that can open real wide (like f/2.8 or f/2.0) and lenses that have apertures with many blades give a very pleasing out of focus background.

More on What is Bokeh and the definition of Bokeh.


A lighting method that involves aiming the main light sources so that it bounces or reflects off of a surface. The light is often bounced off a large white or light object. This could be a wall, ceiling or reflector. The light becomes "softer" because the light is scattered in multiple directions.  

Bounced light doesn't have harsh shadows like a direct light source.

Warning! There are some very important things you need to know before you use a Bulb Exposure setting on your camera.


An accessory which allows you to trip your camera's shutter release without touching it. This helps to prevent camera shake and means you can take pictures with long exposures and not get Blurry Pictures.


There are differences in the way monopods are made. Some are for videographers. Some are for hikers. What is different about Camera Monopods and which one is right for you?

Chromatic Aberration

This lens shortcoming is best described as color fringing. Chromatic aberrations show up in high contrast areas of your photograph, depending on several variables. Learn how to avoid and fix this negative effect image quality.  Fix Chromatic Aberrations.

SDHC (Secure Digital High Capacity)

SDXC (Secure Digital ‘Xtra Capacity)


Reducing the file size of digital data files by removing redundant or non-critical information within a digital image. This makes the size of your digital image file smaller and easier to store.

The large majority of photos are saved in a format called as JPG, which is a compressed file. File formats that are not compressed are TIFF, PSD, and DNG.


The difference between the darkest and lightest areas in a photograph. 

Contrasty photo of tree and sunsetHigh contrast photo of tree and sunset

This silhouetted tree at sunset is a high contrast photo. This side of the tree is getting no light and the sky is much brighter.


Using only part of the picture area by framing a smaller area and cutting out the area outside the frame to improve the composition. Cropping usually refers to using software afterwards to re-frame. You can preferably use your camera's zoom lens to come in close to isolate your subject.

D- Photography Definitions - digital photography terminology


Attached or separated electronic flash that sends and receives information with the camera to ensure proper camera and flash settings to get the right exposure. The camera and flash use information about camera settings like ISO, shutter speed, subject distance, and aperture to determine the best flash output.

DEPTH OF FIELD (abbreviated as DOF)

The distance between the closest and farthest points that appear in acceptably sharp focus in a photograph. This is one of the most important digital photography terms to understand.

It can affect every single picture you will ever take. The DOF varies with the lens aperture, focal length and distance to subject. Read this article on What is Depth of Field.


DSLR - is an abbreviation for Digital Single Lens Reflex camera. A camera that allows the scene to be viewed through the lens EXACTLY as the photo will be taken. DSLR cameras are bigger and heavier than point and shoot cameras and mirrorless cameras. How much do DSLR cameras weigh?

DSLR cameras use a mirror to reflect the camera's view through the lens to the viewfinder That mirror temporarily flips up quickly, out of the way, when the photo is taken.

Anything that is not straight up and down or straight side to side is considered a diagonal.

Diagonals are often used in photography compositions to create more visually interesting photographs. 

Diagonal row of StrawberriesDiagonal Composition of Strawberries

Here are a few example photos comparing photographs of some fences where diagonals were AND were not used.


A zoom-like effect enlarging the central portion of a scene and cropping away what you don;t want in the photo. Not my favorite feature at all!

It's often needed and used with cell phone phones that can't zoom optically (with a lens). You waste the use of the full size of your sensor. Optical Zoom is a much better feature to have.


The number of dots of ink per inch when a photo is printed is DPI. Often confused-it's NOT the number of dots per inch on a tv screen or computer monitor.  That's PPI or Pixels Per Inch. 


Transferring files from a digital camera or other source such as a web site or server to a computer.

When you're downloading from your camera to your computer you can either tether directly with a USB cord or you can remove your memory card and plug it directly into your computer with a memory card reader.

E- Photography Definitions - digital photography terminology


The total amount of light allowed to fall on a digital camera's sensor during the process of taking a photograph. 

It is a product of how much time (the-shutter-speed) the shutter is open, how wide of an opening (the-aperture) and how sensitive (the-ISO-setting) the sensor is. Advanced point-n-shoot and DSLR camera let you decide on some or all of these three factors.


An accessory flash unit that is attached as an add-on on top of the camera or completely separate from the camera. It is not an internal flash which is called "built-in" flash.


The light that is naturally illuminating a scene without any additional light that has been added by the photographer. Ambient light and available light are two other photography terms that have the same meaning as existing light.

F- Photography Definitions - digital photography terminology


A fast lens is a lens that has a large maximum aperture. Here is an article on camera lens basics and fast lenses and why you might want one: All about Fast Lenses


A flash technique used to brighten deep shadow areas even though there may be enough light for a proper exposure according to your camera's built-in exposure meter.

Ideal for portraits. Manually turning on your camera's flash or using a separate, remote or external flash will fill in the darker shadow areas caused when the lighting is coming from behind or from a sharp side angle. More on Fill Flash Photography

Fill flash is also useful if your background is very bright and you want to match the brightness of your subject.

What is a fluid head used for?  It's an accessory that goes on the top of a monopod or tripod that uses a long handle for smooth movements of your camera.

Important when shooting video. Read more about Fluid Heads.


What is focal length ? The technical definition: the distance between the near nodal point of the lens and the film plane when the lens is focused on infinity. Click here for a detailed explanation of Focal Length.  Click here for a focal length-Camera Lens Comparison.


Frames per second is the number of pictures taken within a one second interval. Cameras with high FPS capabilities are great for Sports Photography.

When shooting video, the most common frame rates in video are 24, 25 and 30 frames per second.

Faster frame rates make for higher quality video, particularly with fast moving subjects in a video.


F-stop is a number related to the size of the lens opening (related to aperture). It's actually the ratio of the lens focal length divided by the diameter of the lens opening of the lens.

The larger f-stop number, such as f/11 means a small lens aperture.  Here is a more detailed discussion of the definition of f stop and links to related articles.


means that the camera's senor is the same size as 35mm film. For some information on the advantages and disadvantages of a camera with a full frame sensor, read this: Full Frame Sensor.

G- Photography Definitions - digital photography terminology


Slang. A light blocking device that got its name because it GOesBetween the subject and the light source. I used this term quite a bit in photography school when we did many studio lighting set-ups with large studio lights.


There are many definitions of the word gallery, but on this photography definitions page, we are interested in a photo gallery as a collection or assortment of photographs. Studying family portraits taken by other photographers can improve your portrait taking skills. 


What is a gimbal head? A gimbal head is a device for use on a monopod or tripod.  

It supports and precisely balances the weight of your camera and a long heavy lens so that you can make easy adjustments, left-right or up-down to photograph your subject.

The Lily Camera uses a digital gimbal to accurately follow a moving target.

H - photography definitions terminology


In photography, what is definition of HDR? A photographic technique used where several shots are taken of the same scene at different exposures.

Highlights from the underexposed photos and shadows from the overexposed photos are combined together to create a new picture. 


An image that is mainly made up of light tones, which relatively few mid-tones or shadows. A picture of a polar bear playing in the snow is a good example of a high key photograph.


A graph showing the brightness range of an image. Histograms can be used to make a better judgment if you have a good exposure for your picture.

Full-featured digital cameras and some computer programs can display these graphs. Histograms plot brightness along one axis of the graph and how many pixels at that brightness level along the other axis of the histogram graph.

Digital Photography Definitions That Begin With the Letter I


 An intervalometer is usually a separate accessory, but can be built into the firmware feature of some cameras. It operates the shutter a set intervals over a period of time to create time lapse photography. 

Intervalometer-Shutter CordIntervalometer-Shutter Cord

Using a traditional digital camera, it's fairly simple to turn sequential still images into fascinating timed videos. Intervalometers have several other features for additional creative photography techniques.


The ISO refers to how sensitive the digital camera sensor is. A high ISO number means the sensor is more sensitive to light. In other words, it needs less light to get the right exposure.

This will allow you to take a picture in a darker situation or you can use a faster shutter speed or a smaller aperture and still get a good photo exposure.

J- Photography Definitions - digital photography terminology


The standard format of digital photography files.  JPG is the file extension so a regular image file is named like: thisyourphotoname.jpg.

JPG actually stands for Joint Photographic Expert Group, the folks who came up with the standard.  JPEG was shortened to JPG so that the extension only has 3 letters.

K -Definitions


Also called "main light." The principal source of light on a subject or a scene. The key light is often the brightest light on the subject, or the one that will have the greatest overall effect on the image.


A kicker light is a light the "kicks" in a little more light to a small area of the subject such as a hair light or edge light to create a highlight or more separation from the background.


Kit lens18-55mm Kit Lens

A kit lens is a general all-purpose lens that comes as a starter with a camera body. Usually camera retailers include a basic zoom lens with the camera body.

L- Photography Definitions - digital photography terminology


The range of dark areas to light areas that can be recorded or perceived. Our human eyes have a much, much larger range of latitude than digital camera sensors.


A lighting ratio is the ratio between the main light (also known as the key light) and the fill light. Lighting ratios are used primarily in portrait photography. A light ratio of 2:1 means that the main light is providing twice as much light on the subject as the fill light. For more on this topic click on Light Ratio.

M Definitions Used in Digital Photography


Close up photography of a subject where the image is recorded on the sensor at the same size or larger than actual subject. If you have an interest in macro photography, find out more about it in this related article: Macro Photography. or an entire page on the Definition of Macro Photography.

A megabyte of memory is about 1 million bytes of information. This is the same as 1,000 kilobytes (K) A photograph that is several MB (megabytes) is a higher quality and is suitable for printing.

Usually when photos are used for emailing or for web site use, they are smaller and we talk about their size in kilobytes(KB)


This digital camera term means one million (1,000,000) pixels. Camera manufacturers describe the size of a digital camera's sensor in megapixels and abbreviate the term as "MP".

An 8 MP camera has a sensor that has about 8 million pixels. Caution: sensor size is not the only thing to look at when comparing digital cameras.


Unlike a Digital Single Lens Reflex (DSLR), there is no mirror that reflects the light through a prism in order for you to compose your photo. With a mirrorless camera, you can to see your composition on the camera's LCD screen or by looking at an electronic viewfinder (EVF).

Benro c38f monopodBenro c38f monopod

Sometimes referred to as a unipod, "mono" means one and pod means "leg." A one legged support for your camera. Read up on Monopod Reviews or How to Use a Monopod or read more on the definition of monopod here:  Definition of monopod.


Monopod Heads are the attachments on the top of the monopod that make it versatile and adjustable to different angles. Attaching your camera directly to a monopod without a head will give you the needed stability but you are restricted with the angles you can shoot.

Ball heads are by far the most popular heads used with the pistol-grip version of ball heads being the most versatile and fastest to adjust.


My favorite kind of photography, followed by portrait photography. You likely don't need a definition on this photography term.  I included it here for you so that you know it's such a great type of photography for you to enjoy

A filter you can use to cut down the amount of light that reaches your sensor. This gives you the ability to open up your aperture or lengthen your shutter speed for creative purposes. More on this topic here.


Okay, no definition needed here either, but I wanted to include this term on the photography definitions page so you could find this article on Night Time Photography Tips.


Digital noise has to do with the "grainy" look you find in a digital image. It is more apparent in underexposed images or in the shadows where the pixels on the digital camera sensor did not get enough exposure.

A noisy photo can have speckles or artifacts and often lack sharpness.

O- Photography Definitions - digital photography terminology


The definition of open shade is shade that is in the shadows of large buildings, under big trees or other area that still allows a large light source to illuminate your subject. Benefits of open shade: No harsh highlights from the sun, no squinting, and an even light source.


The different photography definitions of optical zoom vs. digital zoom are important to understand. With optical zoom, you are using the lens to come closer or to include more in your pictures. So, you still are using all of your camera's sensor to record your image.

This gives you the best quality. Digital zoom means you are literally not using part of your sensor to make it appear as if you are moving closer to your subject. You can always do cropping later when you are doing your photo editing.


When a picture is overexposed, the sensor received too much light during exposure. Sometimes a little over exposure is okay. If the overexposure is too great, details in the highlight areas of the photograph are lost forever.

Many professional photographers (ME too) like to shoot in "raw" mode, because the exposure can be adjusted, even after the photo has been taken.

Over exposure often happens when most of a subject is dark, but there are very bright areas in your scene as well. This is the biggest photo mistake when photographing the moon. How to Photograph the Moon.

Photoethnography is the art and science of representing other cultures visually. There is a web site dedicated to this art, including a page on photoethnographers. 


What is a pixel?  "Pixel" is a contraction of the two words: picture element. On an LCD screen, what appears as a single white dot actually consists of three pixels: one red, one green and one blue. White light is actually equal blending of the three colors together.

With most camera sensors, there are actually two, very tiny green light collectors combined with a tiny red and a tiny blue light collector. The camera processes the information gathered from these combined collectors and each pixel has a value for red, green and blue which make up it's actual color.


A Plamp is a photographer's clamp. You can twist them in various ways and they have ingenious clips on each end. Here's an article on Photographic and NON-photographic ways on how to use a Plamp.

I don't use mine a lot, but when I do it works great. This clever term is really the name of a handy accessory made by the Wimberley company. They are long and shaped like a snake.

There are also similar products called McClamps made by FM Photography. These are a very popular gadget used by macro photographers (and others) to hold various objects, useful to act as a third hand.  


A pictorial representation of a person, usually showing the face. There are quite a few posts about Portrait Photography and posing on this website.

R- Photography Definitions - digital photography terminology


Also called camera raw or raw format. Shooting in "raw" mode allows the photographer to process the data later instead of having the camera process the data at the time the picture is taken.

It contains the most information possible from a camera's sensor. Saving the raw image allows us to process it any way we wish, making choices on color, sharpness, exposure and many other variable. Raw files are very large compared to the standard jpg format that all digital camera can shoot in.


Use the reciprocal rule to avoid the unsharpness caused by camera movement when you're not using a tripod or monopod. This rule is a guide to help you figure out what shutter speed is needed to get a sharp photo while hand-holding your camera.

Reciprocal rule illustrationUsing the reciprocal rule, a 400mm lens
would need a 1/400 second shutter speed.

Your minimum shutter speed should be the reciprocal of your lens length. If you're shooting with a 400mm lens, you should use 1/400th of a second for your shutter speed. This assumes you have a real steady hand and use good technique.


The Red Eye Reflections are caused by having the flash or other light source too close to the lens.

In photography terms TTL stands for "Through The Lens."

It is most commonly applies to electronic flash and exposure. TTL flash means the exposure is controlled by reading the actual amount of light reaching the camera sensor and adjusting the length of time the flash fires.

Exposure with flash was originally only manually controlled; then "automatic" flash control was done with a separate sensor on the flash unit. Now it has evolved to E-TTL and E-TTL II by Canon and I-TTL by Nikon.
