Well, there are several things that you can do with a photo that cannot be done with a camera.

Like choosing the hardness/softness of your paper, like, after exposing for the highlights, developing for the shadows, like local enhancing, unsharp masking, solarisations (I admire Man Ray for these) . Etc etc.

I agree that knowing your camera is very important (and I admit that I don't yet know what my digital camera can do - I do miss the spot metering) but it's only part of the whole process.

My opinion of course.

There are no Borg. All resistance is fertile.
