This is usually some sort of S-shaped curve to make the image more contrasty: shadows and highlights are compressed. The picture style specifies a curve which is applied to this input image in order to make it presentable. Which means image pixels record luminosity in a linear fashion.

The raw image of the camera is in linear space. But in this article we are more interested in another property of custom picture styles. The picture style defines some parameters for the image, most notably color handling. These are sometimes called picture profiles or creative styles (on some Sony cameras). Most digital cameras feature settings for picture styles. This is all nice and good, but unfortunately for videographers that’s not the signal we get out of the camera. This is enough to represent accurately dynamic range spanning 12 stops when encoding it linearly. This means that the analog-to-digital conversion on the sensor yields 14-bit values (between 3). The RAW data of a Canon DSLR camera is 14-bit.

The dynamic range of the APS-C sized Canon 550D/t2i sensor is about 11.5 stops and the dynamic range of the full frame Canon 5D mark II is around 12 stops. The ARRI Alexa and Red MX sensors capture dynamic range well in excess of 13 stops. So a dynamic range of 10 stops means a contrast ratio of 2 10:1 or 1024:1.Ĭurrent digital sensors have some pretty good dynamic range capabilities. Each successive stop is double the light. In photography this range is usually measured in f-stops (or exposure values, EV) which is a logarithmic measure (with base 2). Similarly, camera dynamic range specifies the ratio between the luminance of the brightest whites and the darkest blacks that the camera can capture. Scene dynamic range specifies the ratio between the luminance of the brightest whites and the darkest blacks in a scene. Also, we are focused here on Canon picture styles but the principles apply to any DSLR or video camera with 8-bit video. This article talks about dynamic range and picture styles, and attempts to explain the Why’s behind the previous statement.

The thing is, unless you know exactly why you are using CineStyle, then chances are you will get better results by not using it. So after this introduction the following may come as a surprise to you. These folks have extensive experience in color science, image processing and digital intermediate. When Technicolor released the CineStyle picture profile last year it immediately became a hit amongst Canon DSLR videographers.
