Re: Re: Re: Re: MINERAL PHOTOGRAPHY

I believe that digital is vastly less expensive than film, on a per shot basis. With film it is both the cost of the film plus the cost of processing. With digital, it is the cost of storage; and CD-Rs are cheap. In addition there is no expense for taking multiple shots, tweaking light and focus; but with film that gets expensive fast.

Another advantage of digital is the ability to change the plane of focus (without making any other changes) while taking successive shots and then combining them in Photo-Shop to produce an image with continoous depth of focus.

As to quality, I don't think digital will ever equal film. However, cameras today are around 7 megapixels. Unless one wants enormous prints, that is pretty good resolution.
