Film Simulation

A colour and tone rendering designed to imitate the response of a specific photographic film.

Frequency Separation

A retouching technique that splits an image into a blurred low-frequency layer of tone and colour and a high-frequency layer of texture.

Gradient Mask

A mask that fades an adjustment smoothly along a linear direction, digitally imitating a graduated filter.

Post-Processing & Retouching

HDR Merge

Combining bracketed exposures into one file holding a greater dynamic range than any single frame could.

Healing Brush

A retouching tool that copies texture from a source area while blending its tone and colour into the destination.

Highlight Recovery

The reconstruction of detail in bright areas where one or two colour channels have clipped but at least one has not.

Post-Processing & Retouching

Image Stacking

Averaging multiple identical exposures to reduce random noise or to combine content across frames.

SNR improvement = √n count
Post-Processing & Retouching

Layer

A stacked element in an image document that can hold pixels, adjustments or effects independently of the layers below it.

Post-Processing & Retouching

Layer Mask

A greyscale channel attached to a layer that controls where that layer is visible, with white revealing and black concealing.

Post-Processing & Retouching

Lens Correction Profile

A stored description of a lens's distortion, vignetting and chromatic aberration, applied automatically during processing.

Levels

A tonal adjustment that sets the black point, white point and midtone gamma of an image or channel.

Local Contrast

Contrast measured between neighbouring areas rather than across the whole tonal range, which strongly affects perceived depth and clarity.

Luminance Noise Reduction

Processing that smooths brightness variation between neighbouring pixels to reduce the appearance of grain.

Post-Processing & Retouching

Luminosity Mask

A mask generated from the image's own brightness values, restricting an adjustment to a specific tonal range.

Post-Processing & Retouching

Non-destructive Editing
