I use natural light whenever possible. Where I need flash, I bounce off ceiling or walls, never direct. The image above showing my PC setup with desk is not taken with flash. It's just at ISO 1250 with an aperture of F16, and shutter speed of 1 second with the camera mounted on tripod.B. And because the flash makes it look like a police station mug shot for audio gear (IRL w/no camera flash, the lighting in this home office is always very low).
Then again, I'm a semi-pro photographer (semi cause I don't work professionally. Just a hobby)
