## Definition

the act of putting things on top of each other to make a pile. In photography, it means combining several pictures to make one perfect image.

For teachers: the process of arranging objects in a vertical pile; in digital imaging, the technique of combining multiple exposures to enhance depth of field or reduce noise.

## Examples

- The children are busy stacking their wooden blocks.
- Focus stacking allows macro photographers to keep the entire insect in sharp focus by merging several different shots.
- The warehouse manager implemented a new stacking protocol to ensure that heavier crates remained at the base of the pallets, thereby reducing the risk of structural collapse during transit.

## Usage notes

- Often functions as a gerund; frequently paired with 'focus' or 'image' in technical photography contexts.
