Re: Digicam vs. Scanner resolutions

[David Chien <chiendh@xxxxxxx>]

Damn.  Forgot which advertiser had their super high resolution digital 
imaging system that could be used to 'scan' stills at 10,000x10,000+ 
resolution.

They had an advertisement in one of those digital imaging magazines last 
year which showed an extremely high-powered blowup of a small area of 
their sample -- literally showing you the finest details.

Anyways, it the meantime, try betterlight.com or phaseone.com

eg. while this is only a 10,500x12,600 digital imager, it should get you 
going in the right direction (the other one above I talked about goes 
higher -- vaguely remembering it going to 15,000)

For certain, you'll =easily= match and exceed 35mm film quality with 
this 132MP imager ;)

-------------------

Anyways, as quoted from Photonics magazine article with a Kodak film 
scientist, he currently says that estimates of how many MP film's upper 
limit is is approximately 25MP (was 24.xx, but I've forgotten).  And 
that's for the regular stuff not counting TechPan.

Realistically, ~8MP will start to match a quality P&S camera like an 
Olympus Styus Epic, with both achieving ~50lp/mm of resolution in the 
images created.

Naturally, since most 35mm SLR camera lenses of good quality go much 
higher, to 100+lp/mm, you will need to increase the MP of the digital 
caemra you use up to Kodak's figure of ~25MP to match the film and lens 
combo you typically use, and accordingly, the resolution and quality 
you've been getting from that film setup.

Most working professionals have bumped into the limit of traditional 
desktop slide scanners, and thus have jumped up to things like drum 
scans and Imacon Flextight (desktop drum-like scanners) film scanners 
instead for better scans and resolution from their slides.

Similarly, professionals using digital cameras have jumped past the 
usual lot of <6MP digicams into the world of high-end imagers like those 
sold by BetterLight.com and Phaseone.com.  That's because physically, 
you simply can not get more than 50lp/mm of resolution (or even 50lp/mm 
of resolution) from any digtial camera with less than 8MP of image 
information.  Since most pros want their work to exceed the general 
quality of a basic 35mm P&S camera, those high-end imagers are usually 
the way to go.

Happily, those imagers will easily exceed 35mm film and match medium 
format without trouble.  You'll easiy be abel to match and exceed the 
quality of work you achieve today with any 35mm camera setup, and be on 
your way to nirvana.
