What is Knolling?
Knolling, also known as 'flat lay photography', is a photography technique when objects are arranged at a 90-degree angle within a square or rectangular frame and shot overhead.
What are Layers?
are a transparent overlay stacked to create images and effects.
What are Levels?
Levels are the highlights, shadows and mid-tones in a photo.
What are Mid-Tones?
Mid-tones are the areas between the lightest part, or highlights, and darkest part, or shadows of a photo.
What is Noise?
is spots or specks on a photo that appear dirty or dusty. Removing the dots is called noise reduction.
What is Resize and Resample?
Resize means to change an image size by duplicating pixels. Resizing may pixilate images and look blurry.
Resample means to change an image size by filling in more pixels.
What are Shadows?
Shadows are the darkest parts of a photo.
What is Unsharpening an image?

What is 4K DCI?
4K DCI is similar to 4K UHD, however 4K DCI refers to an image or digital screen with a resolution of 4096x2160 pixels. 4K DCI refers to an aspect ratio of 1.9:1.
What is 4K UHD?
Similar to 4K DCI, 4K UHD
refers to images or digital screens with resolutions equal to 3840x2160. 4K UHD
is equal to a 16:9 aspect ratio.
What is 720p?
720p, often referred to as "HD Ready" refers to digital screens and images with an aspect ratio of 16:9 and with 720 horizontal progressive lines.
What is 1080p?
Similar to 720p, 1080p refers to images or digital screens with an aspect ratio of 16:9 that have 1080 horizontal lines that are non-interlaced (I.e. progressive).
What is 1080i?
Images and digital screens with 1080 horizontal lines and whose lines are interlaced (not progressive) are considered to be 1080i.
What is Aliasing?
refers to the process of minimizing or removing completely jagged/sharp edges in a digital photograph, making affected areas appear smooth and natural.
What is an Artifact?
is any distortion in a digital image created as a result of interpolation or image compression.
What is a Bit?
A bit is a binary digit that is considered to be the absolute smallest unit available when referring to a digital file. 8-bits is equal to one byte.
What is Color Calibration?
Color calibration is the process where image source, monitor and printer can be calibrated to use the same color standard. Examples of color calibration standards are Adobe RGB and sRGB.
What is Color Depth?
Color depth refers to the number of colors that are represented by hardware such as a monitor or camera and software such as bit-depth of a computer user's desktop.
What is Dynamic Range?
Dynamic range is the range of brightness and tonality reproduced within a digital image. The wider a dynamic range the greater the tonal values between dark shadows and highlights.
What is Interlaced Scan?
, or video, is a commonly used term to describe video capture techniques where two fields of data are captured a frame apart and then played back in a manner that reproduces motion without flicker.
What are Jaggies?
Jaggies is a common term to describe the 'stair-step' appearance of angled lines in a digital image.
