Is it normal to want to augment the data?

First time LoRA tester here, I got a weird question:

1. Is it normal to want to augment the images (e.g. randomly tilt by <10 degrees) to increase the usability of LoRAs?
2. Would cropping for focus (e.g. clothing, poses) be useful to train more comprehensive LoRAs? If so, how can that be automated?
3. Would color correction or other filters (e.g. contrast, brightness) improve LoRA training?
4. How do you deal with the asymmetry where there are few back-facing images?
