3/7     Does anyone else think the iPad3 isn't really that much better
        than the iPad2?  I don't really understand the hype.
        \_ 5MP camera?  My 1-yr-old Android phone has a 8MP auto-focus camera
           (plus a 1MP focus-free one on the front.)
              \_ The iPad camera seems like a joke to me.  The iPad is just
                 to big to be useful for taking pictures.  Maybe it makes

9/28    A lot of photos I take come out blurry. A lot of them are clear,
        too, but the proportion of blurry photos is high. This has led me
        to take more photos than I otherwise would in hopes of getting a
        clear one. I took some photos of the Rio grande and they
        were all awesome, but the next day I took photos of landscapes
        and almost all of them were blurry. Could it be the camera or is

4/8     I want to by my mom a point and shoot camera for about $150 because
        she's running around with this 1 megapixel camera from back in the
        day. I looked at Canon and Nikon, but I am not as into this stuff as
        some people on MOTD are. I take photos with my Blackberry. What's
        a good choice in that price range? Definitely not more than $200.
        \_ Canon has the best point and shoot cameras.  The A1100 or A495

10/16   Interesting new Canon P&S cameras: G11, S90.
        http://www.bhphotovideo.com/c/find/newsLetter/PowerShot-G11-S90.jsp
        BTW, has anybody used the new D10 [not the old 10D] ... any thoguhts?
        I'm trying to pick between {my G10 + buy waterproof housing} or
        a buy a nw D10 (beach, boat/raft/kayak, snorkel ... not scuba).

Data normalization DxOMark Sensor ranks cameras based on real-life photographic scenarios Objective measurements of RAW images are an essential basis for any analysis of digital cameras, but such measurements were neither possible nor available until now. DxO Labs has developed a new scale for digital camera image quality performance, called DxOMark Sensor, to serve as an additional tool to help photographers rank and compare digital cameras. This scale is based on three underlying metrics, Color Depth, Dynamic Range and Low-Light ISO, each one tied to a real-life photographic scenario: landscape, studio & portrait, and photojournalism & sport. Read more on the logic behind the DxOMark Sensor scale architecture. This interactive graph shows the ranking for approximately 50 currently-available digital cameras on the DxOMark Sensor scale and its three metrics (click on the different tabs to view the performance and ranking of cameras versus each metric). You can switch the x-axis for time, price range, or resolution, as well as filter the ranking by brand, resolution, sensor size, time and price (USD). You can also access the comprehensive set of RAW-based measurement data, curves, and plots for any given camera by clicking on its product sheet (left column). listappareil FusionCharts needs Adobe Flash Player to run. If you're unable to see the chart here, it means that your browser does not seem to have the Flash Player Installed. The DxOMark Sensor scale aggregates the performance values of its three constituent metrics, Color Depth, Dynamic Range, and Low-Light ISO. Each metric is associated with its real-life photographic scenario (studio/portrait, landscape and sports/action respectively), and compiles the results of thousands of objective digital camera sensor measurements. On the DxOMark Sensor scale, the higher the score, the better. The scale is kept open, anticipating that sensor technology will continuously improve over time. Color Depth or Color Sensitivity indicates both the breadth of the color spectrum and the degree of fine separation between colors that a camera can distinguish. The higher the color sensitivity, the more color nuances can be distinguished, which is of particular importance for portrait and studio photographers. This metrics indicates the maximum Dynamic Range, or the greatest possible amplitude between light and dark details a given sensor can record. It is plotted in EVs (exposure values) or f-stops, with each increase of 1 EV (or one stop) corresponding to twice the amount of light recorded. High dynamic range is an essential consideration in landscape photography. As cameras improve, the highest ISO setting to produce 30dB images will continuously increase, making this scale open. The Low-light ISO metric is of primary importance in photojournalism, sports and action photography.
