I’m making this post as a way to start a discussion about the techniques one could use to make their animation or render seem as if it was taken by an actual camera and thus have imperfections of an actual camera. To start off, the more basic options anyone can use include camera shake and trail the camera. Basically, it means making sure your camera doesn’t instantaneously follow perfectly when something fast paced is happening and also make sure to add modifiers to the animation curves and mess around with them to get a shaky camera that picks up shakiness when it moves quickly and is very subtle about it when it is barely moving or not moving at all.
In terms of compositing, you often find some of the more common ones to be motion blur or color grading. Both of these can be done with a very simple node setup. In regards to the color grading, you can use one simple node such as the color correction or color balance node in your setup to change things. More complex systems, however, will give you more control and thus allow you to do more so one node normally isn't exactly what you want. Further detailed explanations and more examples would be great for continuing this conversation going forward. Any input is welcomed.
