  • Yes, but they do help to show how much a person can change the look of his pictures through adjustment of the in-camera settings.
  • From another thread, I see you're using a Nikon P7800. In that other thread, you got the good advice to reduce exposure to protect highlights then bring back shadow detail in post-processing. I ...
  • Since you're comparing the 70D to your telephone and using the phrase "touching them up," I assume you're shooting JPEG. If you haven't tried it already, you can change the out-of-camera look to ...
  • I see.  Something I hadn't properly taken note of before was that this is a backpacking trip, and I imagine you might walk more energetically than the sauntering pace that is the most I care ...
  • What was it about the neck strap experience that you found so awful?  I have to say that I loved my E-300 on a neck strap, but hated the experience with an E-450 (and gave that camera to my ...
  • Roughly yes, though it varies a bit depending on the crop factor. The Canon has a 1.6X crop factor, and 50 times 1.6 equals 80. My Samsung has a 1.5X crop factor so a 50mm is equivalent to 75mm, ...
  • If the sample images you've seen were taken on full-frame cameras and you like the field of view you're seeing, then a 35mm lens would be similar for an APS-C body.  I find that to be a highly ...
  • Replied in and output size?
    I've kept a Popular Photography issue from 1991 in which seven different 50mm lenses were tested (not the fast f/1.4's but the more moderately-priced ones ranging from f/1.7 to f/2 in lens ...
  • I don't own your camera or the lens I'm suggesting. I agree with another poster who mentioned going to the forum specific to this line of cameras for more information. Nonetheless, I'll offer my ...
  • I see your point. No.  No offense taken; it just presented itself as an example, a poor example I now see.  Perhaps a better example was the OP's starting off the thread by referring to the ...
  • It doesn't help for you to say that Nikon's article is incorrect without providing a better explanation from a credible source. How about this one: "ISO speed is analogous to ASA speed for ...
  • "Photography is built on the three pillars of exposure: shutter speed, aperture and sensitivity. Shutter and aperture are controls for adjusting how much light comes into the camera. How much ...
  • I had forgotten about Mr. Wallace's videos about exposure.  Since you posted this, I've been able to watch six of them in this series on YouTube.  The third one might help a friend of mine better ...
  • I'm sure you find it cute to substantiate your misstatements by selective trimming of the text, but I don't see how it advances the conversation. Then why go on about asking for a quote? When you ...
  • I think you didn't read all of Michael's suggestion, which included, "It's a rather long discussion, rather than a specific quote. If you are interested in what Feynman actually said, listen to ...
  • Which is a shame since having a place to ask questions of the experts was part of the purpose for which that forum was created. Photographic Science and Technology: a home for those wishing to ...
  • Yes: Welcome to the Photographic Science and Technology Forum, the place to discuss the finer details of sensor design, quantum efficiency and demosaicing, and to argue about the most technically ...
  • For smartphone photographers, depth of field is so great that judging focus is probably not often an issue.  Even the more basic concept of seeing what you're taking a picture of doesn't bother a ...
  • Replied in 18-55 kit zoom
    It's not onerous; the kit zoom weighs 7.9 ounces while the 35mm f/2 would have been 6.9 ounces. You being a Pentax guy, it's possible you know exactly what quality my lens offers. Samsung got ...
  • Replied in 18-55 kit zoom
    That all makes perfect sense.  The last film SLR I got was a Contax 139Q, and I bought the 35, 50, and 85mm Zeiss lenses for it, along with a Yashica 75-200 zoom; over time, the only lenses I ...
