In image processing, computer graphics, and photography, exposure fusion is a technique for blending multiple exposures of the same scene into a single image. As in high dynamic range imaging (HDRI or just HDR), the goal is to capture a scene with a higher dynamic range than the camera is capable of capturing with a single exposure. However, because no HDR image is ever created during exposure fusion, it cannot be considered a true HDR technique (the image does look better on displays, but the resulting bit depth of the image is equal to the input depth, unlike on a true HDR image where a greater bit depth allows storing more detailed intensity changes).
Exposure fusion in photomicrography
In photomicrography, the exposure fusion is often the only way how to acquire properly exposed images from stereomicroscopes. One of the software solutions designed for photomicrography is the HDR module for QuickPHOTO microscopy software. This module can be also combined with Deep Focus focus stacking module to solve another problem, which is shallow depth of field of stereomicroscopes.
