  • Of course. If any post-production platform dies you loose almost all your post-production work. The rendering parameters could be extracted from the DNG file to approximate the original rendering. ...
  • It is a mystery to me why DNG is considered evil. The DNG format is open-source. DNG does not mandate lossy compression. So what's the risk? So let's consider some appalling pessimistic scenarios. ...

    Choosing convince over flexibility is not mad. While I only use raw, I accept the view that some people prefer convenience over flexibility that might not be required. This isn't a life or death ...
  • Only overexpose over brighten highlight regions that are not essential to the photograph you wish to produce. When all the highlights are critical, then you just accept the shadow regions' signal ...
  • Replied in Exactly !
    Think about signal-to-noise ratio, not jut the " ever increasing ISO ".
  • The X100S sensor's microlenses are designed specifically for its fixed lens. The microlenses' optical properties match the angle of the light rays that exit the lens rear element. SO the ...
  • ..... Ian, The most important thing you can do to avoid "image degradation" is use your camera's base ISO or the lowest ISO above base ISO compatible with the task at hand. Base ISO is the native ...
  • It is useful to consider the signal level and with the noise level together. And increasing ISO only compensates for analog underexposure of the sensor (using fast shutter speeds and, or narrow ...
  • If one has a extremely important appointment and must travel at 60 MPH to be on time, then a Fiat and Ferrari doing 60 MPH are perfectly equivalent withe regard to the purpose of the drive. The ...

  • Exactly. When strong outdoor light reflects off of shiny surfaces such as hardwood flooring  or polished stone counter tops, a polarizing filter is useful. If you use off-camera flashes to match ...
  • Dan, The Color filter array is a separate technology from the sensor semiconductor technology. Apparently the DxO data indicates Pentax is using CFAs that perform well under the DxO test protocols. ...

    Thanks for the clarification. The purpose of maximizing exposure is to maximize signal, particularly in the shadow regions. For many cameras with recent data-stream designs the increase in signal ...

    Exactly what noise source are you refering to?
  • It turns out histograms observed by ETTR and maximizing exposure appear similar. This does not mean ETTR and minimizing exposure have the same motivations. Every image in every camera is recorded ...
  • Reichmann's initial motivation for ETTR is not relevant. The actual benefit is to maximize the signal-to-noise ratio of any objects in the frame that are important to the image you envision.
  • Replied in Good Question
    Any parameter that increases DOF (distance, aperture, focal length) increases the latitude of FP. In principle this is not a disadvantage as if it peaks, it should be in focus. Of course there is a ...
  • Thanks for the link to some data. The Nikon's VR has similar characteristics . This behavior is not a design or manufacturing defect. It is intrinsic to feedback loops. To detect movement you must ...
  • There is nothing wrong with the Bayer model. The problem (color tonality/rendering) is caused by the temptation to modify the data until it is just barely compatible with the Bayer interpolation ...
  • HCB' prints intentionally include a thin area showing the uneven boarder where the film emulsion ends. Regardless of his camera handling, he did not crop to compose.
