The default values for a CinemaDNG clip use Apple’s library components and not stored clip data. Because CinemaDNG is a variation of digital still photography processing, the sliders and terminology will differ from those of the other camera raw codecs. Since CinemaDNG is an image sequence format, a Frame Rate pulldown selector is available along with Codec and Resolution.
Baseline Exposure is a control originally designed to equalize files coming from various camera sensors. That’s because the DNG and CinemaDNG formats are based on generic sensor specifications. It will default to 0. Sliding it to the right brightens the image, but there is little need to adjust it. Brightness adjustments should be made using the Exposure slider.
Boost is effectively a contrast control. The default is full right (value of 1). As you adjust the slider to the left (towards 0), the image will become flatter in appearance. Boost Shadow elevates the darker areas of the image. Boost and Boost Shadow can work in tandem and may often yield similar results. When the Boost control is set to 0, Boost Shadow will have no effect. While Boost Shadow elevates shadow information, Bias yields the opposite results. Increasing the Bias slider will crush shadow information and darken the lower range of the image.
There are three buttons to enable EDR Mode (extended dynamic range), Sharpening, and Lens Correction. EDR will only affect the image when Bias has been adjusted to the right. When you enable this function, the darker, highly saturated areas of the image will display an increase in the brightness of the chroma.
If you enable Sharpening, this will slightly enhance image detail. The Lens Correction function is designed to correct chromatic aberration of a lens.
