Leica CL raw file (DNG) analysis
As usual when new Leica cameras come out, I took a quick look inside a DNG from one of Leica's new Leica CL cameras:
The camera name shows as "LEICA CL" The image data is 14-bit. There is no compression used in the DNG I looked at. The DNG version is 1.4, with a "backward version" of 1.3.
What is color?
So finally, after many years of searching, I have an answer to the question that torments all who go down the digital color rabbit hole.
This is from XKCD, brought to my attention via an article on the Digital Transitions website about the Phase One IQ3 100mp Trichromatic.
The Leica M10 and dynamic range revisited
Back in January, when the new Leica M10 was introduced, there were claims that the improvement in dynamic range from the Leica M240 to the M10 was of the order of 1.5 to 2 stops.
dcpTool for the Mac is now available
dcpTool has been available for quite a while as a command line application for Windows and the Mac. But now it available in the form of an easy to use Mac app, with powerful batch processing capabilities. dcpTool for the Mac is available from the App Store.
11How to remove the lens corrections from any raw image
Many cameras embed lens corrections into raw the raw files that they produce. Generally, that's a good thing - straight lines stay straight, etc. For an example of lens corrections in practice, take a look at this post about the Leica SL.
But, as the saying goes, "there is no free lunch".
Cleaning Leica M10 DNGs
Those of you that have read the Leica M10 raw file analysis post will know that M10 DNGs have more baggage in them that is typically the case for a Leica DNG. I've put together a little app to clean them up, called DNG Cleaner (Mac only for the moment).
AccuRaw has become AccuRaw EXR
AccuRaw users might have gotten a bit of a surprise recently - AccuRaw has turned into AccuRaw EXR, and is now at version 3.
The reason for the name change is that the focus of the AccuRaw product has changed a bit, based on what users were actually doing with it.
Fuji GFX 50S compressed raw support is now available
Good news - AccuRaw, AccuRaw Monochrome and PhotoRaw now have support for the compressed raw format that Fuji use in the new GFX 50S. Previous versions of AccuRaw/PhotoRaw had support for the regular uncompressed RAFs, but not the compressed version.
AccuRaw and PhotoRaw now have Fuji GFX 50S support
Updated: AccuRaw and PhotoRaw now have support for compressed and uncompressed RAFs.
For those that have been asking me about AccuRaw and Fuji GFX 50S support, I'm pleased to say that the version on the App Store as of today has support, although only for uncompressed RAFs.
The Leica M10 and Dynamic Range
I've been reading various articles, posts, etc on the web that deal with Leica's new M10. Many of those suggest that the improvement in dynamic range from the Leica M240 to the M10 is of the order of 1.5 to 2 stops. But I find that difficult to agree with.
2Leica M10 raw file (DNG) analysis
As usual when new Leica cameras come out, I took a quick look inside some DNGs from one of Leica's new M10 cameras. Usually, there's not much to see with Leica DNGs - they are typically text-book vanilla DNGs. But with the Leica M10, things are bit more interesting.
6Non-clipping workflows are important for EXR images
In a previous post introducing AccuRaw EXR, the new version of my AccuRaw raw processing software, I mentioned the importance of a "non-clipping workflow" for the promise of the EXR format to be a reality.
AccuRaw EXR's highlight control curves
Now that the AccuRaw EXR beta is out, one of the questions I'm getting is how the new highlight controls work.
The control curves are below. Note that these curves are on a linear scale, and 1 is white. So anything above 1 is "blown".
The AccuRaw EXR beta is now available!
AccuRaw EXR is a new version of AccuRaw with support for HDR (High Dynamic Range) images in OpenEXR format. OpenEXR is a high dynamic-range (HDR) image file format developed by Industrial Light & Magic for use in computer imaging applications that uses floating point data.
