Monochrome2DNG Beta 0.9.2

What's New in Monochrome2DNG Beta 0.9.2

  • This Beta adds crop options:
  • Crop mode
  • Some converters and stacking applications ignore standard soft crop tags, thus "Save cropped area only" option is added.
  • Crop margins
  • Helpful if some unusable areas are left in the corners or close to the edges of the sensor; CFA is only partially removed there, for example.

Minor Changes

Minor Bugs Fixed

FastRawViewer 1.4.8

This new release addresses two reports indicating some problems with opening RAF files from certain Fujifilm cameras on Mac platform, and a few suggestions towards improving user interface.

FastRawViewer 1.4.8

Minor Interface Changes:

  • EXIF Display: 'File Modified' date is now displayed using system locale settings (Short date + Short time)
  • Edit date range dialog (Sort/Filter panel): OK is now 'default button', and it is activated by pressing the Enter key

Minor Bugs Fixed

FastRawViewer 1.4.7 Release

Big thanks to all of the testers for Technology Preview I and II, your feedback was invaluable.

The new version of FastRawViewer 1.4.7 doesn’t require one to turn on the new features through additional hotkeys, everything is already on.

FastRawViewer. 1.4.7.
  • The changes are as follows:
  • With the new new strategy of processing JPEG representations (both embedded and Lone), opening files has become times faster.
  • Processing RAW data on the GPU: rendering is changed instantly with the change of the rendering parameters (WB, Exposure, Contrast); higher-quality demosaicing is applied to Bayer images (that is, for the vast majority of cameras).
  • The interface rendering speed has also increased somewhat.
  • If you prefer the Windows Explorer / Finder-like behavior for selecting files, you can switch to it.
  • Several bugs have been fixed, many minor improvements have been added.
  • New cameras' support added.

New Features and Improvements

New Old Approach to Dynamic Range

In today's world, "dynamic range" (DR) has become, in the minds of (many) photographers one of the main characteristics of a digital camera.

Unfortunately, the public data on DR is limited to "DD - ISO sensitivity" graphs and tables. With this, the nature of noise (for example, random noise, banding) isn't accounted for, however the noise character is important for visual quality.

In reality, any practicing photographer knows that the degradation of the image in the shadows (or because of low exposure) happens gradually. With the lowering of exposure, small details disappear, the contrast between bigger details diminishes, color fidelity becomes worse. Depending on the quality demanded of the image (which will depend on presentation size, viewing distance, other viewing conditions such as screen resolution, etc.,), the practical dynamic range for the specific camera will be different, even for the same ISO setting.

SonyPixelShift2DNG, Beta 0.9

New in Beta 0.9

  • Better metadata handling
  • Better font-size autoselection on 1st run
  • 0.9.1: Added DNG ActiveArea tag to set mandatory cropping area
  • 0.9.2: Better handling of file/folder names set in non-default system locale/language

Monochrome2DNG, Beta 0.8: File Converter for «Monochrome-Converted» Cameras

Almost all digital cameras that are released today are color cameras. Nevertheless, there is demand for BW (Black and White) cameras because of reduced artifacts and higher resolution of resulting images. And many photographers want BW cameras with the same lens mount as their main (color) camera, so that they can use the lenses they already own.

Converting a color camera to BW is done by removing the CFA (Color Filter array). However, during such conversion, the firmware of the camera doesn’t change, and the camera doesn’t know that it’s become monochrome, which leads to several problems, which Monochrome2DNG - a file converter for «monochrome-converted» cameras - is going to address.

DPRSplit Beta 0.8: File Splitter for Canon 5D Mark IV / Dual Pixel Raw files

Canon 5D Mark IV's sensor has a somewhat unusual pixel arrangement: each pixel is composed of two subpixels. If Dual Pixel RAW mode is enabled in the camera, the resulting CR2 file contains two images, or two frames: one composite, made from reading both subpixels, summed; and the other is made out of one set of subpixels.

In essence, in Dual Pixel Raw mode, the camera records into one file some equivalent of two shots, bracketed by (approximately) 1 EV.

The DPRSplit application is intended to extract this additional frame out of the CR2 taken in Dual Pixel RAW mode, and save it as a DNG. Resulting DNG files can then be opened and processed in (practically) any raw converter featuring DNG support.
