Composite Photography Quiz

A composite is a single finished image assembled from multiple source photographs or graphic elements. Each component is selected, masked, and blended in a layered editing workflow to produce an image that could not have been captured in a single frame.

A composite only looks real if every part seems to have been photographed together. The camera height, angle and lens perspective must match, and the light must come from the same direction with the same softness and color. Mismatched light or perspective is the most common giveaway.

In compositing, the plate or background plate is the primary environmental image into which subjects or additional elements are placed. Matching all other elements to the lighting, perspective, and color of the plate is the central technical challenge of the composite.

The pen tool traces a precise vector path around a subject's edges, which can be converted to a selection and then a mask. Subject selection tools use machine learning to detect and select edges automatically, which the pen tool refines in areas where the algorithm misses detail.

Air contains haze, moisture and dust that scatter light between the viewer and distant objects. The farther away something is, the more of that scattered light lies in front of it, so it looks lighter, less contrasty, less saturated and often bluer. This cue adds depth to landscapes and composites.

Blending modes calculate how each pixel value on the active layer combines mathematically with the pixel value directly below it. Multiply darkens by multiplying values; Screen lightens by inverting and multiplying. Each mode produces a distinct visual relationship between layers.

A contact shadow is the small, very dark shadow right where an object touches the ground, where almost no light reaches. Without it, a subject placed into a composite looks like it is floating. Adding a dark, tight shadow at the contact point grounds it.

Elements in a composite usually come from photos with different light and color. A single color grade over the whole image pushes them all toward one palette, so they look like they were shot at the same moment. It ties the parts together rather than just adding color.

A physically inconsistent reflection breaks the illusion of a composite by suggesting the subject exists in a different space than the background. Matching reflection angle, intensity, and color to the new environment is one of the fine details that determines whether a composite is convincing.

In a composite, global light means every element looks lit by the same light: the same direction, height, softness and color. If the background sun is on the left, highlights and shadows on the added subject must agree with it. Conflicting light is one of the quickest signs of a fake.
