  • Replied in can be
    Part of the problem might also be in the way the question is posed. The Mike Johnston article asks, is photography art?, a yes-or-no question that leads to two dichotomous answers: yes, ...
  • Replied in wrong forum
    I believe the term you're looking for is "less technically-minded," at least according to DPReview's stated purpose when they created the forum: "The second new forum is Photographic Science and ...
  • The author gave a few good reasons for shooting JPEG as opposed to raw, though, as others have pointed out, some of these may have had more relevance in 2005 when the article was written than it ...
  • I missed the early wranglings about dress color.  The first picture I saw was in the form of a poll asking if you saw a white and gold dress or a blue and black dress.   To my eyes, it was and ...
  • The Furtman article referenced by the OP had a couple of interesting, and perhaps contradictory, pictures of JPEG use. One was that of shooting JPEG with the idea that you're going to do further ...
  • I find the examples and explanations offered by Fred Parker to be very useful, particularly the exposure value and exposure factor relationship charts. http://www.fredparker.com/ultexp1.htm
  • Replied in Accurate color
    Others have already mentioned the need for a consistent, controllable setup over time, and that this means working with artificial light (such as photoflood lamps or flash). One feature on your ...
  • What you're referring to as exposure compensation is often called the exposure value (EV) compensation setting. It's common to see it referred to it simply as EV in many books and articles. http:// ...
  • On my camera, if I'm in aperture-preferred mode, changing EV changes the shutter speed.  When in program mode, changing EV changes either shutter speed, aperture, or both.  When in ...
  • Yes. In their review, this site said, "The base sensitivity of the sensor used in the D3S is ISO 200. There is also a Lo 1.0 mode that attempts to mimic ISO 100 but it's effectively just ISO 200 ...
  • Most of the people commenting in this forum recommend voting on all entries. I often prefer to vote on only a few, those that I really like and can give four or five stars to. DPReview says, "We ...
  • Replied in Noise
    In general, yes. I see in previous threads that you have had concerns about image stabilization and a yellowish color cast under low light conditions. From this I gather that getting better ...
  • "If the retailer is located out-of-state and is not engaged in business in the state, the state cannot require the retailer to collect North Carolina's tax. However, some out-of-state retailers ...
  • Replied in focal length
    I don't think that what's unusual is that the photographer is using primes, but that here is a landscape photographer restricting herself to just a 50mm lens.  That may not be unusual for the ...
  • I like that phrase. When I've considered the concept of image-making envelope, the picture that comes to mind is Grandpa's two cameras, a Kodak Super 27 (if memory serves correctly) and a Yashica ...
  • If I counted correctly, there seems to be five other responders who said that automatic bracketing is important to them, one who said that he uses manual bracketing, and three for whom bracketing ...
  • Replied in dynamic range
    It's even difficult when trying to determine the dynamic range available for JPEG shooting. Each manufacturer has its own take on what makes an attractive OOC picture, so default settings are ...
  • Sony's floppy-disk Mavica cameras probably convinced more people to switch from film to digital than any other camera. Popular Photography and PC World magazines report that the Mavica market ...
  • Replied in dynamic range
    My assumption is that they are from out-of-camera JPEG's at default settings (since that seems the norm for those sites that do give details about their testing procedures), but all Shutterbug ...
  • Replied in no bracketing
    I used an SD14 for a short time a few years ago, stopping due to frustration over ongoing sensor debris issues, and recently became a Sigma user again when Sigma USA had a refurbished DP2S to ...
