richard stone's recent activity

  • But this whole discussion is getting quite odd, as one might predict, because we have no idea how well or poorly the camera works. Maybe it is a worthy competitor to the various top of the line ...
  • I'm very pleased with the 17-50 f2.8 OS on my sdQ (NOT H). I think the OS is a big plus for the camera. Yes, the 30mm Art might be a little bit "sharper," but the OS makes for ultimately more ...
  • Lea I have been intending for a long time to say a proper thank you for posting all the excellent images you have made with the various Sigma cameras. I particularly like that you make such ...
  • It's very interesting that you are getting such a good (very good) result with Silkypix. SPP generally wins out, even considering its limitations, when compared to "outside" "RAW" conversion ...
  • But...You seem to be saying that we are dealing with something resembling a visual placebo effect: We see what we think we should see, or what we like looks better. Assuming we can tell which ...
  • I think the answer to your question is that there are clearly more details in the high res image. I have done the comparisons myself and it quite obvious at high magnification, viewing at over 100 ...
  • As I see it (pun unavoidable, I think)  blurred detail doesn't just become invisible as the image gets smaller, the blurred detail is perhaps not consciously perceived, but still has an effect on ...
  • So, if you were to make concluding sentence or two, or a short paragraph, in regard to this image detail concern, on screen and off, what would you say? And as a bonus question, what action, if ...
  • An impressively good result.
  • I hope you're happy with the camera. You posted some very appealing shots. Thanks for that. Richard Ps: I am reminded of a post I saw long ago, in one of the initial user reviews of a DP camera, ...
  • Ted I don't know the answer to your question, but your edited image looks very good. Richard
  • The amusing part is that Sigma/Foveon "images" have a lot in common with transparency/slide film...And it makes people somewhat distressed: They want the latitude that the digital version of print ...
  • I actually use my sdQ and 17-50 OS lens as my usual go everywhere camera. People, buildings, as a tourist, and around town. It works quite well, assuming you are mindful about high contrast ...
  • Yes. I can understand the reasoning behind the various comments, but the reality is that it is a beautiful image. And I'm sure it was a challenge. Both the camera and the photographer did well. It ...
  • As I see it part of the issue is that Sigma needs a new group of buyers and owners. I'm fine with the sdQ. I can see the new model being much better, because the L model should be excellent. But ...
  • I like the image. It's a very delicate shot. Excellent color, as I see it. Sharpening with SPP is a bit of an issue on its own, because it tends to increase the noise in the image. Or make it look ...
  • Yes, a very nice result. Richard
  • The issue here can, I think, be stated in terms of right and wrong. In general, if it looks good to the viewer, it's right, and if it doesn't, it's wrong. Here we have allowances made for each ...
  • I think, sadly, that the great flexibility or latitude of CFA sensors has somewhat reduced the use of actual "physical" graduated filters. But the Sigma/Foveon cameras in use react much more like ...
  • Yes, RT works. Used as described in your post it can noticeably reduce luminance noise and improve the appearance of images significantly: The improvement is obvious. Luminance noise is a big ...
