  • Replied in Faster shutter
    Raising shutter speed, in and of itself, won’t cause graininess or increased noise if the exposure isn’t changed, which would be the case if the aperture is correspondingly opened up more, letting ...
  • My iPhone does it, but it’s more of a toy.
  • That’s not the sensor, that’s a photo of the mirror reflecting the focus screen, which is illuminated by light coming through the viewfinder. To see the sensor, the mirror has to be locked up, and ...
  • That’s the quaila problem, and it is unsolved, and gets close to the core of subjectivity and consciousness. Currently, it is within the realm of philosophy, and not psychology, biology, or ...
  • Replied in Raw
    Raw image formats contain image data, but in an ambiguous manner. There is more than one way to convert this raw data into an image, and this is not a straight-forward, completely scientific ...
  • Replied in Lottery?
    Don't they already have a lottery for getting permits to enter some parks?
  • Replied in Stuck pixels
    Those look like stuck pixels, and according to the manual for your camera, that is sensor damage caused by cosmic rays! The Canon manual states that running a manual sensor cleaning should help ...
  • Replied in D200
    Correction: I still have a D200 in my gear list. But yes, I do occasionally use it. For me, the camera has good ergonomics and fits nicely in my hands, certainly better than my old D7000 and much ...
  • Someone once jokingly said that 'TIFF' is an acronym for "Thousands of Incompatible File Formats". The kind of TIFF you are thinking of, the standard kind used for images, is Baseline TIFF, a ...
  • Those would be great for a start. Photography can be an expensive hobby, but both of those have the capability of taking photos of excellent technical quality at a fairly low price. You might want ...
  • Since you are a beginning photographer, I’d suggest skipping the purchase of additional lenses until you understand the kit and then only when you routinely find yourself limited. Learn photography ...
  • Replied in NEFs are TIFFs
    Nikon NEF files, as well as all other raw files that I know of, *are* TIFFs. You could probably just rename your recovered files with the .NEF file extension.
  • Replied in Auto1 or Auto2?
    The problem you see is an Adobe problem, not strictly a Nikon problem, as raw processors have an extreme influence on color rendering. The latest versions of Adobe have a wide array of color ...
  • Agreed. I suspect there is slight overexposure. However, the highlight image data may very well be preserved in the raw file, and these 'lost' highlights can be pulled recovered, up to a point.
  • Replied in Alternatives
    That’s a problem with DoF calculators. Another problem is that the calculators imply far greater accuracy than you can actually easily get: this is because DoF calculators use a very simple lens ...
  • Replied in Highly desirable
    Old time photographers noted that older lenses were often better than new ones, and this was due to the coating that developed on lens surfaces over time, which helps reduce reflections and so ...
  • Strength scales nonlinearly with size, which is purely a geometric phenomenon. Strength goes up with the square of height, and weight with the cube of height, and so strength per pound of body ...
  • Silent Shooting has a number of limitations and may cause problems, as documented here: https://helpguide.sony.net/ilc/1640/v1/en/contents/TP0001306070.html But I don't think that it is directly ...
  • Replied in Some hints
    These photos look mainly alright to me. How did you get your expectations? Of course there is room for improvement. (1) Don't pixel peep. Evaluate your images whole and entire at a reasonable distance ...
  • What you really have to worry about is zero frequency events of high amplitude.
