HDR Color Matching Workflow

High dynamic range

Scanning normal color negative images for post-production and visual effects using modern high-end technology allows users to capture the dynamic range of the colour negative. Film archives, however, typically manage large volumes of historic images, and require specialist equipment, which enables the capture of an even greater dynamic range rather than image resolution. This is particularly important when managing black and white (B&W) recorded images on either print or negative stocks which have a high dynamic range (HDR).

Traditionally, HDR scanning is done using a multiple exposure method during which a scanner ‘stops the film’ to capture images at different exposure levels. Images are subsequently recombined into a single HDR image, a process that significantly slows the rate of scanning.

Both, Scanity HDR and also DFT POLAR HQ allow for HDR scanning, covering extended densities from archive films and deliver clean and high quality scans, without any increased noise level or other artifacts. DFT scanner are designed to cover densities well beyond of what is possible on other scanners on the market.
