Using advanced effects

Now we’re stepping up our game with some advanced effects. They’re a notch above what we’ve seen before, and a bit trickier, but don’t worry—we’ll guide you through them. In this section, we are going to see the following advanced effect concepts:

• High Dynamic Range (HDR) and Depth Map
• Applying advanced effects

Let’s start by discussing some requirements for some of these effects to work properly.

Remember the Depth Map from our last chapter? Some effects need more than just the rendered image; they require extra data like this to really shine. Some effects not only work with the rendered image but also need additional data. We can first discuss the Depth Map, a concept we discussed in previous chapters.
