  • I shoot medium, which on my camera is 2400 X 1600. I use "normal" file quality, which on my camera for that file size represents about a 9:1 JPEG compression ratio ("fine" is 5:1 and "basic" is ...
  • I'm glad you two understand, but I can't seem to grasp the idea of ISO being irrelevant to the JPEG shooter. I can understand a camera having only one ISO setting, with no adjustment possible, but ...
  • That might depend on how you define image quality. In the context of an out-of-camera JPEG, the only way you can increase the amount of light used--slower shutter speed and/or wider aperture--is by ...
  • Another poster had mentioned the sunny F/16 rule, and I have to say that that is a concept that clicks with me. An important assumption behind the rule is that the exposure will result in ...
  • This last bit is somewhat confusing.  If you're using an out-of-camera JPEG, then changing any of the three parts of the exposure triangle will change the brightness of the image (unless ...
  • Replied in No
    While that may be true, I think we are operating within the specific, limited context of how DPR has changed the way they test and report on dynamic range. After all, the OP did post in a DPR ...
  • Replied in No
    I was always more interested in highlight dynamic range, too. It's curious that a couple of posters above have said that there's no such thing as highlight or shadow dynamic range. There certainly ...
  • It could be argued that the 35mm f/2 with image stabilization or the faster, slightly longer 50mm f/1.8 might be more useful for low light situations, but the 40mm pancake offers a stop and a half ...
  • For me and most people I know who use cameras, photography is about recording memories of people, places, and events that are important to us. A good photograph shows me something that the person ...
  • It does seem rather inconsistent or uncaring on the part of DPR, doesn't it? Then again, maybe someone on staff looked at it and decided it was fine, as in an answer to a similar situation a few ...
  • I believe that "judge each image on its own merits" simply means that you are to apply the two criteria in #1 to each picture without reference to how it compares to other pictures in the ...
  • Replied in XMas Lens
    On your crop-sensor Canon, the 50mm becomes a short telephoto (80mm equivalent) rather than a "standard" or normal lens. I've found this to be a great focal length for people pictures at office ...
  • I don't have any advice for you, but I am curious about the articles you found with such clean ISO 6400 shots.  I just took a look at a handful of reviews, and those all said that noise and/or ...
  • Perhaps I'm using the wrong terms, but when I move the cursor, I can see the title and some information about shutter speed, aperture, ISO, and focal length, but not what I'm thinking of as the ...
  • From past threads, it seems a lot of people vote in slideshow mode.  This means that your excellent title and description of the photograph might not even be seen by a lot of voters (one of the ...
  • Out of curiosity, I took a look at your challenge entries and found a few that I remembered liking. One was Cathedral Rock Sedona, which came in 109th (jointly) in the Natural Rock Formations ...
  • With a CRT monitor, any resolution setting could be used at or below the maximum resolution of the monitor to fill the whole screen with a great-looking image.  It didn't matter that I started ...
  • Replied in JcatG
    It looks like the OP asked his question 5 days ago, and the first response was 15 hours ago. Perhaps the OP simply gave up hoping for a response after all that time and hasn't logged on to this ...
  • Replied in 100%
    I do occasionally take a picture while seated, and I fall well short of 6 feet even when standing, but I'm not trying to be creative with my framing, I'm just trying to get a visual reminder that ...
  • I'm not sure what is incompatible here. He said there are things you can do with a 17mm lens that you can't do with a 105mm lens. As one article says, "Using a short-focal-length lens from a close ...
