Very surprised to see this much praise of Lucas’s use of digital cameras and CGI.
They (digital motion picture technologies) are useful tools, but not all-purpose ones. The way Lucas used them, and the way Hollywood has generally used them since they became widespread, are as crutches. Because storage space is cheap, settings can be changed quicker, the final result can be previewed in real time, and digital editing has so many more bells and whistles, there is less motivation to put effort into getting a good shot. This applies moreso to effects, as the digital world does not have the limitations of the physical world, allowing thought out and naturalistic shots to be replaced by hyperactive, sensory overloading flash and impossible scale. Early CGI like Jurassic Park and Terminator 2 looked better because effort was taken to get it to fit in with live action footage by not shoving it in your face and often augmenting it with practical effects. Now it’s the other way around, with the live action being an afterthought.
As for digital cameras, they’re best used in situations that demand a small, lightweight, or remote camera.
