Aug 2, 2023 · With a history stretching back almost 200 years, the dictionary of photographic terms has grown enormously. From the letters found on lenses, through the names of obscure lighting accessories, in the glossary below you will find a full A to Z of what these terms mean.
- Aperture
- Aspect Ratio
- Camera Shake
- Card Reader
- Chromatic Aberration
- Crop Sensor Camera
- Depth of Field
- Double Exposure
- Drive Mode
- DSLR
Aperture is defined simply as the opening in the lens through which the light enters and passes through to the camera.The aperture is made up of a series of blades that form a circular opening and it is located inside the lens. Think of the aperture like the pupil in your eye. It opens and closes to adjust the amount of light it lets in so you can ...
The aspect ratio is what determines the shape and proportions of your image.Standard digital cameras use a 3:2 aspect ratio. What that means is if you need a square image for Instagram, or a panoramic one for a Facebook banner, your image will need to be cropped to fit those proportions. Most photo editing programs have a crop tool where you can se...
Camera shake is a vibration or movement of the camera which can cause blurry images. It is most often caused by hand holding the camera at a shutter speed that is too slow. Any slight movement of your hands while taking the photo will cause camera shake. Follow this rule to ensure you are using a fast enough shutter speed to eliminate this problem.
A card reader is a small device that connects your camera’s memory card to your computer. The drawbacks of downloading directly from the camera are: 1. It is much slower than using a card reader. 2. If the camera battery dies the card could error which could result in partial or total image loss. Most card readers are less than $30, just get one!
Chromatic aberration occurs when the three colors (RGB) captured by the camera as separate layers on the sensor, are not properly aligned with one another. This is an anomaly that occurs usually with entry-level or lower quality lenses, particularly wide-angle ones. What that looks like is a slight color outline around the edges of things, most com...
You may have heard this photography term before and if you are new to photography and just got your first digital camera, it is likely a crop sensor one. The other alternative is full-frame which is over $2000+ just for the camera body. The short definition of a crop sensor camera is one that has a smaller digital sensor than the old 35mm film form...
The depth of field is the amount of your image that is in sharp focus.It is affected by two things: 1. The aperture chosen (smaller aperture = more depth of field) 2. The distance to the subject Here are two extremes as examples. The old house above was shot at f/22 so that the doorway and the chair and setting inside would both be sharp. This opti...
A double exposure is photography technique that involves capturing and combining two images into a single frame, resulting in a unique, artistic effect where elements of both images are blended together. This can be achieved either in-camera or through post-processing software, allowing photographers to explore creative possibilities and produce vi...
Drive mode is about how many and how fast the camera captures images.Most cameras have a few different options as follows: 1. Single shot– the camera takes one single image with each press of the shutter button. 2. Continuous low burst mode– the camera takes photos continuously as long as the shutter button is held down. This is the slower of the t...
This is an easy one, it is just an abbreviation for Digital Single Lens Reflexwhich is a standard interchangeable lens camera. If you can remove the lens on your camera, and you see a mirror behind the lens – then you have a DSLR. If there is no mirror and you see the imaging sensor, then you have a mirrorless camera (more on that later). In the di...
The meaning of JIGGLE is to cause to move with quick little jerks or oscillating motions. How to use jiggle in a sentence.
- Aperture: The part of the camera that opens to let light in. The f-stop or f-number is the measurement of how open or closed the aperture is.
- Depth of field: The difference between the closest and farthest in-focus objects in a photo. A shallow depth of field means that relatively close background objects become blurry.
- Dynamic range: The difference between the darkest and lightest tones in an image — the range of dark and light that a camera is capable of. Darkest and lightest hues are very rarely pure black or pure white.
- Exposure triangle: The combination of aperture, ISO, and shutter speed, which determines the time and intensity of light being let into the camera. Different exposures in film and digital images alike are achieved by adjusting these exposure settings.
JIGGLE definition: 1. to move from side to side or up and down with quick short movements, or to make something do…. Learn more.
Apr 24, 2024 · 12. DSLR Camera. DSLR stands for “digital single lens reflex” camera. It is one of the most popular types of advanced cameras, along with mirrorless cameras (see “mirrorless” below). The two defining aspects of a DSLR compared to other cameras are its digital sensor and its reflex mirror.
Sep 18, 2023 · The exact definition is: Focal length measures the distance, in millimeters, between the “nodal point” of the lens and the camera’s sensor. “Nodal point” may sound complicated, but it is simply the point where light converges in a lens. Here’s a simple diagram showing the focal length of a lens, based upon this definition:
