Nikon is now NASA's #1 flight camera.

Poor Bob C. is stomped again. Then again you have to wonder what Bob
might use a 22MP or higher for? Does he know that a 4MP D2Hs makes the
same quality 8X10 prints and has even better control over dynamic
range?

Bye, bye, Bobby!


Who cares about 8x10 prints? What about running the pixels into a DSP for
analysis. What kinds of analysis? Like looking for slight ground collapses
due to tunnel, a surface wake in mm from a submarine running hundreds of
meters below the surface, changes in water reflectance due to oil films,
subtle changes in wave structure due to winds, old river beds under the
sand, buried objects in the sand, land mines, etc.

Go play with your toy camera and your 8 x 10's. Science has much better and
more sophisticated uses for photography. Since you know so much about
cameras, how many lines of C code does it take to write a recursive low pass
filter using a bilinear transformation to discern the chromolesence and
luminesence characteristics of a black and white 16 MP digital photograph?
Tell us Robbie! Tell us!!!!

Bwaaahahahahahahahahahaaaaaa!!!!!!!!!!!!!!!!!!

Scorched like a flounder in lava!!!!!!!!!!!!!!!

Amen!

What the hell is "Chromolesence", and what's it got to do with black and
white images?

Talk about a beating! Bobsprit has been made into pulp.

Oh the humanity!

It's the humologuous transformation of a D1 type system conformal to a one
to one mapping of the gray scale. The drawback of this method is dynamic
range reduction but it does give remarkable contrast enhancement. It's very
much like the way the eye works. The eye has a timewise great long term
dynamic range and short term great sensitivity. The eye takes time to adjust
to nominal light intensity and then can discern fine levels of light
intensity. In the eye it's driven by chemical concentrations, in humologuous
gray scale transformations it's mathematical. The running average window is
much longer which establishes the baseline interjection recursive elements.
From this baseline, non logarithmic methods can be used to determine the
intensity granularity of the digitized black and white image. Linear
analysis gives much greater sensitivity than logrithmic analysis, plus phase
information is not lost. The reason it's called "chromolescence" is that the
original work was done for color images, which is a 7 vector space and then
reduced to black and white images which are a 4 vector space. Just search
Rabiner, Gold, Oppenhiem, Schafer and Tribolet.

Glory!

Bad new, Bob. Huffy (under a different name of course) makes premium
high end bike frames and developed the breaking systems along with
Mafak some years back also found on today's racers.
Seems like you know about as much about bikes as you do cameras! Funny
that you own neither.

And for scientific applications in the field, the #1 lens series are
the Nikon Micro line.


Nope. Their coatings outgas.

Thanks Bob, all is clear now.

Hallelujah, in colour.

Do you mean Mavic breaking systems?

http://penncycle.com/itemdetails.cfm?ID=7114


Or Mafac?

Mafac are the old dual pivot side pull brakes:

Here's a high end bike from Trek, notice the brakes:

It's Dura Ace toad-boy!

Premium high end bike frames! Tell me, what are they made of? What makes
them premium?

You don't even know the difference between Tange and Columbus!

aaahahahahahahahahahahahahahahahaaaa!!!!!!!

Hooked by a camera and run over by a bike!!!

Glory!

How does the resolution, grey scale, et al compare to 4x5 and 8x10 film?
