JPEG
Stands for Joint Photographic Experts Group, which is a commonly used file format for storing compressed digital images.
JPEG artifacts
Distortions or visual anomalies that can occur in an image compressed in the JPEG format, typically seen as blocky or blurry areas.
Juxtaposition
The act of placing two or more elements or subjects’ side by side in a photograph to create a contrast or comparison.
Jib Arm
A mechanical arm or crane used to provide smooth camera movement or elevated shots in videography and cinematography.
Jump cut
A type of editing technique where a sudden transition occurs in a video or film, creating a jarring effect.
Jaggies
Jagged, stair-step-like edges that can appear in digital images, often caused by low-resolution or poor image processing.
Joiner
A type of photographic collage or composite that combines multiple images to create a larger, more detailed composition.
Journalistic photography
A style of photography that focuses on capturing real-life events, news, and documentary subjects in an unbiased and truthful manner.
Jump flash
A technique where the flash is used to freeze motion or capture a subject in mid-air, typically used in action or sports photography.
JPEG 2000
An advanced image compression standard that offers higher image quality and smaller file sizes compared to traditional JPEG. But it has some compatibility issues with photography gears.
Jitter
Small, rapid movements or vibrations of the camera that can result in blurred images, often caused by shaky hands or unstable surfaces.
Jumping the frame
A creative technique where the subject jumps or leaps out of the frame, creating a sense of energy and dynamism.
Jaggies
Jaggies are rough, stair-like edges seen in images when resolution is low.
This happens mostly when an image is enlarged too much or when sharp edges are poorly rendered.
JPEG Engine
A JPEG engine is the internal camera processing system that converts RAW sensor data into JPEG.
It controls:
- sharpness
- contrast
- saturation
- noise reduction
Different camera brands have different JPEG engines, giving different “color science”.
