    And what kind of business would that be? If you're thinking stock, there are millions of "beautiful, gorgeous landscape and travel photos" in existence today on microstock and other sites that sell for peanuts. Plus, digital image quality far surpasses slide films of that age so many stock companies won't take digitized film images. I'd say don't put in the huge effort that it will take.

    Like it! Excellent framing of the owl.

    If you can't log in, perhaps issues with your account are causing your problems with Lightroom. You should not have to have an Internet connection all the time.

    Because of the G9's small sensor, f/4 would be like f/16 or so on a full frame sensor. Dust will definitely show up at f/4 with this camera.

    It has nothing to do with being an FX lens.

    The Sigma 50-100mm f/1.8 ART lens is a fixed aperture zoom and has excellent IQ. Heavy beast, though.

    "though it did seem rather dark" It needs to be completely dark. Turn off the safelight and let your eyes get accustomed to the dark. Look for light leaks. Also, the fog test is a good idea.

    Adobe RGB is a color space not a paper profile.

    Dust on the sensor will show up more when shooting at smaller apertures as the other Alan said, so sometimes they show, other times they don't.

    The EOS mount has a larger internal diameter than the FD mount. Basically, the "hole" is too small.

    Yes, slow films are less sensitive to light, but they are very usable in good light as James' "Sunny 16" exposures point out.

    You can't get a 7360 x 4912 image with a DX lens on a D800. The image will be 4800 x 3200 pixels (15.3 MP) in crop mode. Get an FX lens.

    You can produce HDR images from hand-held shots, so I think most any reasonably sturdy tripod, and more importantly, good ball head would do the trick.

    Kenko tubes have a smaller inside diameter hence the vignetting. No baffle.

    Certamente, não parece ser o culpado...
    Great image!

    There is "reciprocity" like what your initial post was talking about, e.g. f/4, 1/125th, ISO 100 produces the same exposure as f/5.6, 1/60th, ISO 100. Then there is "reciprocity failure" where that no longer holds true at very long or very short exposure times because of how file emulsion responds to extreme exposure times.

    With a DSLR camera, macro mode doesn't change the minimum focusing distance, it just forces the camera to use smaller apertures. What camera are you using?
  22. alan_olander1664878205
    Both lenses you are talking about are FX. There are no 50mm DX Nikon lenses. The AF-S will focus on your camera. The AF-D will not.
  23. alan_olander1664878205
    The 17-55mm f/2.8 is a DX lens, not the 17-35mm f/2.8.
  24. alan_olander1664878205
    You can set the saturation to whatever you want in camera or do it in post. Not sure what you're talking about.

    Send JPG's, you'll never notice the difference.
