  • First, there are some good shots here regardless of your age. But, as I think you understand from your question, things could be better. I'm all in favour of encouraging beginners but not to the ...
  • Any straightforward lens. macro or not, should focus all the way from its closest focus distance to infinity. Put a teleconverter between the lens and body and that remains true. Macro lenses are ...
  • I forgot that the OP told us he wants FOV of, or equivalent to, the 24mm he uses/used on film. To that extent I know that a camera restricted to 25mm carries at least one compromise compared to his ...
  • First, it isn't a red herring: it's fundamental to understanding http://www.dpreview.com/forums/post/55690360 What is the red herring is pixel count, as I explained at the end of that post. This ...
  • No, I don't. What I do is read their questions to discover what they're asking about. If they ask specifically about DSLRs I briefly explain the differences between different grades and makes. If - ...
  • In principle, nothing, but ... ... there isn't one camera that can do it all. So you have to compromise and carry the camera that's nearest to what you want: and what you want is unlikely to be the ...
  • This link is to the Adobe suite of instruction videos https://helpx.adobe.com/photoshop.html It also has a link to the online user manual, which you can download as a PDF. As far as fun is ...
  • I disagree with this general statement: see my other posts in this thread. Subject to other factors that I'll discuss below, FF cameras have about 50% advantage in resolution as seen in prints (or ...
  • Pretend for a moment we're still in the film era. We'd take a roll of film and cut it into strips, then make contact sheets with all the images from the roll on one sheet. If using 35mm film each ...
  • I believe I was the first. What I said was: "If you aren't bothered about DOF control your best bet is probably a small-sensor camera like the Panasonic FZ1000 http://www.dpreview.com/reviews/panas ...
  • You mean someone drawing a pencil portrait would start with the eyes because they need to be sharp, and then move out as the pencil gets blunt to create DOF? What grade of charcoal for best bokeh ...
  • For the output image to have the same brightness the shutter needs to be open for longer, so in fact reducing aperture size doesn't let in less light. Then you need to hone your intuition. What ...
  • If you do, yes - but why would you? This thread is asking why lenses score better on FF than on crop and that's what I explained.
  • I started from the fact that the objects looked bigger than the tulip seeds in my shot; the only shot with EXIF shows FL of 171mm and the only lens I could find (admittedly on a quick look) to fit ...
  • Perhaps if you paused in your writing and read the many replies here explaining it you'd learn to understand.
  • Replied in ???
    Considering the Pentax DSLRs of all grades have 100% VFs that come only on higher models from others, I don't understand this.
  • Read the words I've made bold. Yes, on an APS-C sensor it does indeed use only the central part of the image circle - that's why it needs to be enlarged more. Go back to resolution measured in ...
  • Replied in Wrong question
    This isn't the question in your thread title: that question was why a "full body" camera with small sensor. As other people have pointed out, in the same family the crop-sensor bodies are smaller ...
  • Photoshop includes focus stacking modules which do all of that; and that's what I use. But crashpc was talking about doing it manually and I was pointing out the difficulties in doing so. Incidenta ...
  • It's not much to do with Europe, but what you like to capture in your photos. I use 8mm on APS-C - 12mm FF equivalent or twice the width/height if 12mm on M43 but that's because I like it. No ...
