How it works: Take a photo with your phone of the scene you want to capture with your camera, then upload the photo here. LightRead reads the photo's metadata and uses it to make its best guess at the ISO, aperture and shutter speed to set on your camera for a similar exposure.
Select a photo to see the suggested camera exposure.
LightRead provides an exposure estimate rather than a guaranteed meter reading. Results depend on the phone's camera settings and the EXIF data retained in the uploaded photo.
