DBW Camera Scan LightCheck is a dedicated desktop application that measures brightness variation across your camera scanning setup, helping you identify uneven illumination before you start digitising your negatives.

A light panel might look even,
but your camera can see the difference

Uneven illumination can affect the quality of your black and white film scans, leaving one area of a negative brighter or darker than another. Even a good quality light source may not produce perfectly even illumination, and lens vignetting or other optical factors can also influence the result.

DBW LightCheck helps you measure what your camera actually sees, rather than relying on a visual judgement of the light source.

A SIMPLE WAY TO CHECK YOUR SCANNING SETUP

Measure Your Light Source in Three Simple Steps

Capture Your Light Source

Position your camera as you normally would when scanning film. Remove the negative and film holder, keeping the camera position, focus, aperture and light source unchanged. Photograph the illuminated surface using your camera's
RAW format.

See How Even It Is

LightCheck displays the maximum brightness difference relative to the centre of the image, measured in stops.
A visual grid shows where the greatest variation occurs, and additional measurements compare the corners with the centre.

Load Your RAW File

Open DBW Camera Scan LightCheck and load your original camera RAW image. There is no need to convert the file or use an external RAW editor.
The app processes the RAW data locally and measures brightness across the image.
