20 stop dynamic range - can any digital system replace?

I think you owe it to yourself to try digital.

Any camera manipulates the image. Digital is just further advanced technology.

HDR and DRO will give you an effective 20 stop range. Just because it's modern in no way means it's illegitimate.

Horse and buggies are nice, but cars are so much easier.

You can go on a photo road trip and see your images immediately. For a lot less cost and less stress on the environment.
