  • Well, they are complex, not simple at all, and do require thought to be used well. Lots of beginners see the overwhelming number and variety of adjustments. What is important? What are they used ...
  • Replied in Pixelation
    Pixels aren’t in reality square blocks of colors; rather they are sizeless geometric points.  The square blocks you see is only one rendering choice, namely the “nearest neighbor” method. The ...
  • The definition of "computer" keeps moving upmarket. Back in the old days, a simple device with an embedded microcontroller was called "computer controlled" and there was no debate about it. Even ...
  • Replied in It's good.
    That camera is completely capable of producing top quality images. What often differentiates entry-level cameras such as this one and pro cameras is typically just the build quality, ergonomics, ...
  • Replied in Try this
    Take a photo of the blue sky. Use the largest f/stop available. If you can see lots of black smudges in your photo, then that is likely dust on your sensor. This is typical and to be expected with ...
  • "Larger" percentage in the video images. OK, in the first video, it does appear that the model's eye is similarly sized or at best slightly larger, roughly 100 pixels across, as in your daughter's ...

  • Get a hard drive with either a USB C or a Thunderbolt 3 connector. These are rather rare, but it will avoid you having to buy an adaptor. Plug it into your computer, and go into the Mac’s Settings; ...
  • I'd first go over the Wikipedia article to see if that can tell you whether or not to proceed further. The book I linked is an old version of a standard textbook on the subject, and while it does ...
  • Complementary relationships do not have a straightforward, laboratory-measurable, analytic formulation. You can't simply measure the colors and plug in the color temperature into a calculator and ...
  • What you want to do will require a lot of careful research. At the very least, you'll have to investigate the color properties of your printer inks under your given light source . Just because you ...

  • Could you upload a couple of samples for us to look at? There are some cases where distortion changes with focus distance, and your software may only adjust for distant focus. DxO has excellent ...
  • That camera can deliver images that are at most 5472 x 3648 pixels, and so anything wider than that is upsampled, interpolated detail. But that usually isn't a problem. "Dots per inch" are pretty ...

  • As a photographer, you basically own, and are responsible for, everything within the frame, including the frame itself. For example, here you have the subject centered in the frame, which is ...
  • Replied in Nikon F series
    The Nikon F series, like the F2 through F5, which had a large array of accessories, such as replaceable viewfinders, which aren’t available with contemporary cameras.
