In other words, Expand is one of the ‘attributes’ of the film profile itself, namely its contrast properties. This makes an important difference between Expand and ordinary Levels or similar tools. Therefore, when the black and white points correction is performed, the information in shadows and highlights is not clipped by post-correction, instead it is compressed by the profile itself, thus avoiding hard clipping and smoothing the roll-offs. However, an important advantage of Expand tool is that it does not correct the result of the applied film profile, but rather adjusts the profile itself, so that its dynamic range corresponds to the contrast of the source image at the Input section. The idea behind Expand is to make a ‘final scan correction’, and it would be logical to apply this tool immediately after the film profile (similar to typical Levels, which are commonly used for such correction). But we decided that the most correct location would be between the Input and Film Profiles modules. It’s not an easy task to place the Expand tool in the Dehancer Pro diagram. But for simpler understanding you can treat them in a such way. In DaVinci Resolve, there are no direct analogies to the blending modes used in Dehancer. Parallel ‘nodes’ are mixed with each other in certain modes. This scheme can be roughly treated as a node diagram in DaVinci Resolve. Therefore additional text comments are required for better understanding. It is quite difficult to show such a complex structure in a two-dimensional scheme. The transformations are in turn categorised into color (Color Space Mapping / Filtering) and spatial ones (Spatial/Frequency Domain Transformations). Both analysis and transformation can be performed with input data obtained not only from the previous but also from earlier stages of processing sequence. However, the interface of Dehancer plugin represents a typical pipeline, which is most convenient for the colorist.ĭehancer image processing chain includes both the transformations of the source data and the preparatory analysis for further transformations. Within Dehancer Pro, the processing of source material has a more complex hierarchy, where the nodes may be arranged into several parallel ‘layers’, but also interact with each other in different combinations and sequences. Usually image processing is considered as a linear sequence of tools and filters, which are applied sequentially, one after another. To give colorists a better understanding of how it works, we have developed a diagram showing the internal tools structure and their relationships. Dehancer Pro OFX plugin provides a rich toolset for realistic and high-quality film simulation.
