The "correct" exposure is less a matter of accurately reproducing a contrast range than the technique of setting a mood.
I have to photograph on overcast days, and this process can handle the extreme contrast range and deep shadows [of the forest]," Hutchins said.
Maximizing the image's "black level" for the greatest contrast range and detail depends on eliminating all stray light.
Many current generation video cameras suffer from a "video look" due to a limited contrast range, a maximum HD resolution sensor, poor quality optics and lenses, the use of heavy video compression for file recording and poor integration with NLE software metadata management.
The embedded warp & blend capability, Constant Light Output (CLO), unmatched color performance over time, and dual iris system with optical filters for a great contrast range, guarantee that images can be displayed true-to-life in any simulation system.
The system offers the highest resolution on the market, at 20 lp/mm (line-pairs per millimeter), as well as a very high contrast range of 4,096 shades of grey, enabling the detection of even the smallest micro-calcifications.
With built-in High Dynamic Contrast Range (HDCR), even image washout from high ambient light conditions can be eliminated.
This way, the contrast range is reduced without altering any of the colour effects, creating an accurately exposed image across the whole of the frame.
A high contrast, anti-reflective glass shield increases contrast range and creates a sharp picture rivaling more expensive HD panels.
