Canon EOS 5D’s Dynamic Range
Multiple Exposure and High Dynamic Range
Multiple exposures are possible in-camera and can be recorded onto a single file using 4 distinct settings for control. When in Additive mode, this closely resembles making multiple exposures on film and layers each exposure; manual exposure compensation is required. Average mode layers the images and automatically compensates for the final exposure, eliminating the unintended possibility of gross under or overexposure. Bright mode is specifically designed for photographing in uniformly dark scenes with a bright subject, such as a studio environment. Dark mode functions inversely, and helps to eliminate overly bright sections of the image including reflections and highlights.
A High Dynamic Range (HDR) mode is also incorporated and allows for the creation of HDR images in-camera, reducing the time needed to manually overlay images in post-production. When using this mode, a series of 3 bracketed exposures are made of the same image, then automatically integrated into the same frame, resulting in a photograph without blown highlights or blocked up shadows and a long middle range of tones. This mode is especially useful when photographing scenes with a great deal of contrast.
