: What about lens flare and such? The article gave a few reasons how
digital
: lenses are optimized. Nothing in that article was true about the
: differences?  Im not trying to argue just wish you would elaborate if you
: are going to make such statements here. Thank you.


I haven't read the article, but how do they proclaim to have dealt with
lens flare and why would this phenomenon be viewed as a digital/film issue?

lens flare results from any non-image forming light entering the lens,
bouncing around the innards of the lens elements and the camera and off the
surfaces of the lens elements.  Eliminating/reducing it has been achieved
MOST effectively by using lens hoods- any other method is a compromise
based on convenience.

there have been way too many shrill and mischevious claims made by digital
manufacturers and too few people prepared to thoroughly test and challenge
their claims lately.  The very basis of digital photography is still very
analogue - analogue mechanical lenses with quality variations, analogue
monochrome sensors, analogue chromatic filters, analogue squirts of ink
onto analogue paper, analogue monitors.  Software, ie computer programs
whether in camera, in computer or in printer handle the digitised image but
at any step in the process where humans want to interpret the image we
interface on an analogue level.

In the mathematical world, digital may be a viable reality but the laws of
phisics.. well

Voice or no voice, the people can always be brought to the bidding of the
leaders. That is easy. All you have to do is tell them they are being
attacked, and denounce the pacifists for lack of patriotism, and exposing
the country to greater danger."
