In the last lesson, we'll explore how to use an ST map to warp an image with maximum control, and minimal image filtering. To start, we'll talk about what an ST map is, and how we can create one. Next, we'll talk about the advantages of warping with ST maps vs. traditional methods, and how to speed up heavy camera projection setups. Finally, we'll end with a technique to add natural motion to otherwise static stock elements by stacking & time-offsetting a series of warped ST Maps.
In the second lesson, we discuss image filtering, showing detailed examples of what each filter does to your image. We'll touch on why node concatenation is important, and how it works to retain detail in your images. We also talk about how image filtering can produce different results depending on the relationship of pixel values, and how we can use different colourspaces to our advantage.
In this lesson, we'll take a look at how the 7 knobs in the Grade node work together, and what they do to the pixels in your image. We'll then talk about the mathematical differences between the Grade node's Gamma knob, and the Gamma node. After looking at the mathematical functionality behind the Grade node, we'll finish by touching upon the most technically-accurate method of matching black levels.
