![]() ![]() ![]() The trouble is, all cameras interpret Rec.709 differently. Some manufacturers have introduced cameras with “hyper-gamma” or gamma modes with a film-like response, which stretch the gamma curve even further to get more dynamic range. Usually a camera manufacturer will include a variety of these in their cameras, and most of them can be adjusted by the user. These in-camera adjustments are usually referred to as Picture Profiles, Scene Files or Looks. You can also make adjustments to the sharpness and detail of the image. These new cameras allow the user to make adjustments to the image that alter the cameras response to things such as colour, contrast, black levels, and knee. ![]() Today’s professional cameras allow you to go way beyond the limits of standard HD (rec.709) to get more dynamic range, without straying too far from the HD standards. Back in 1984 RCA introduced the first CCD imager in a television camera, the CCD-1 and it wasn’t long before CCD cameras would eventually have dynamic range capabilities that would exceed both the display dynamic range and the Rec.709 gamma function.
