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.

Lightroom, XMP, Windows, and Removable Storage

As Adobe Lightroom Windows users know, this application has been oppressive for users of removable media (disk drives, flash cards), imposing some limitations that puts image culling applications that produce XMP files (including FastRawViewer) in a bit of a bind. It's impossible to cull/rate/label files right on a flash card - they first need to be copied onto a local disk, XMPed, and then imported into Lightroom from there.

Aside from problems with flash cards, the same happens with removable USB disk drives. If Lightroom detects the disk as being removable, it wil neither read nor write XMP files from or to that location.

Since we're a bit overwhelmed with the questions regarding this problem, and the answer "that's just Lightroom" is both overly repetitive and not very satisfactory, we suggest the following lifehack.

SonyPixelShift2DNG (Beta 0.8): Convert Sony A7R-III Pixel Shift Mode Shots to DNG

In order to streamline the workflow with the raw shots taken in the new Pixel Shift Multi Shooting mode offered by the new Sony A7R-III camera, and provide a way to use popular RAW converters (Adobe Camera Raw/Lightroom, Capture One, and some others) for processing these shots, we’ve developed the SonyPixelShift2DNG application, which converts Sony A7R-III shots taken in Pixel Shift mode to DNG.

The resulting DNG files can later be processed in familiar applications like Adobe Lightroom / Camera Raw, CaptureOne, Iridient Developer, Luminar, and others.

One Way to Get Spot-On Exposure for Your Shots

Practically every day, one can see threads on photographic forums where members discuss the various different modes of automatic exposure, trying to find the right one. As a rule, these discussions result in the same question – what compensation to automatic metering ought one set to get consistently good exposure? It turns out that no autoexposure mode universally guarantees good out-of-box results.

We are going to demonstrate that one of the ways of getting good exposure is metering while using the in-camera spotmeter on the lightest part of the scene that needs to maintain full detail (white clouds, snow, etc.) and applying the appropriate compensation to the exposure recommended by the spotmeter.

The shot taken with  spotmeter exposure and +3 EV in-camera correction, opened and adjusted in FastRawViewer
