There’s a new short series on the Maxxon/Cine4D learning channel on compositing elements into 3D in believable ways. Some of the techniques are not software specific. In the first episode they’re looking at ways of eyeballing camera position and focal length by interpreting perspective. Very well done, can be useful background for many things we do every day. > **[DPP: Compositing 3D Into Videos and Stills - Week 1 - Camera & Light...](https://www.youtube.com/live/VGnVO6C-RAI?feature=share&t=513)** > > Demystifying Post-Production: Compositing 3D Into Videos and Stills - Week 1 - Camera & Light Estimation (Eyeballing)Join the Maxon Training Team for an exc... ---

also related in the keen tools pin tool(free for nuke) you can throw in geomertry and have it guess focal length based on alignment its siiiick honestly such a lifesaver. Should run in nuke non-commercial also
