I love the contrast of the original version, especially the dark areas. Unfortunately, the dark areas have low contrast and look fogged -- as if they were underexposed -- on this (uncalibrated but ...

Well, you asked for C&C as far as I can tell. And since I had already spent time on it, here's my take on it. The brightest whites should be set to values of near 255. The snow in the upper ...

Oh, yes, that's the idea.  But now you need to edit it.  Think about the brightness values that you want.  For a start, the sunlit parts of the snow can be pure white.  No detail is needed there, ...

#2 is elegant.

I don't understand the appeal of converting color to B&W.  It seems like one is just taking away part of the beauty for the simple reason that many great monochrome pictures have been taken in the ...

Outstanding picture, but you went paragliding in that weather?

Clean your lens.

Image quality is spectacular for stars at f/1.8.  Also for 15 seconds.  Did processing clean up the star images and remove coma, or is that just a spectacular lens?

"While Linear Polarizer are made of 2 layers of glass, 2 adhesive & one PL film, The Circular Polarizer must have the Quarter Wavelength Retarding (QWR) film."

A quarter wave plate is colorless...

"It seems to be strange to observe HUGE deviation in transmission among abovementioned specimens! It is close to impossible to obtain the polarizing film with such a low transmission of polarized...

"Only strange thing is how they get transmission of over 50% for the polarising filter? Did they use polarised light as a light source?"

Yes.

"For NON-polarized light ...you can not get more...

No, not over-done.  Not only are they artistic, but probably also realistic.  The subject was contrasty, and the images should be also.  The first one is a bit purple for my taste, but remember, ...

DR is limited by flare from lenses.  Some cameras are at or close to the practical limit right now.

1. You do not really want circular polarizers. But if that's what you have, reverse the one on the bottom. 2. The polarizers must be on both sides of the subject. (I.e., below and above subject. 3. ...

Amazing. Great job. I like it!  Please post more.

For $10 you can buy a USB 3 card reader that's only slightly larger than a U.S. or Canadian quarter. You don't even need a cable.

Beautiful!  Thanks for posting.

You may have trouble with strain in the objective.  It causes birefringence in the objective and interferes with the image of your sample, but it shouldn't be too bad.  Microscopes made for the ...

Wow.  Hard sell.  I really have to admire your work.  :)

OK, just one last bit of explanation. The ruler has to span the depth of field. In order to see clearly what is in focus and what isn't, each end of the ruler has to be well outside the depth of ...
