Affinity Photo isn't one of my products, but I have been following it closely, and trying out the betas as they came out. It is now out of beta, and I know that a lot of readers of this blog are looking for alternatives to being forced onto the Creative Cloud model.
Affinity Photo is worth taking a look at. It's loosely a Photoshop competitor, but much, much cheaper. It doesn't of course have all the stuff that Photoshop has, but it has a lot of capabilities, probably all that most photographers will need. However, you should note that (a) it's Mac only, and (b) the raw demosaicing is pretty primitive - the X-Trans rendering is just nasty. Guys, you really should have come talk to me about that raw engine :)
There is an introductory special on at the moment, $39, which is 20% off, so this is the time to take a look. You won't be buying much at all from Adobe for $39.

Good news in a difficult year - all the macOS apps that I support - AccuRaw EXR, AccuRaw Monochrome, pcdMagic, CornerFix, dcpTool (both the GUI and command line version), DNG cleaner and pcdtojpeg - now are all available with native Apple Silicon versions for blazing fast performance on Apple's new "M1" processor. Download are in all the usual places.
Enjoy.

pcdMagic for Windows - the only currently available app that can convert Kodak Photo CD images with correct color and at full resolution - is now available on the Microsoft Windows Store.
This great news for users:
- The Windows Store version has a free trial mode that allows the app to be tested without any commitment.
- The Windows store handles all updates automatically.
- There's no need to keep track of license codes.
The Windows store only supports the latest versions of Windows 10. However, for users of earlier versions of Windows, you can still purchase pcdMagic from the FastSpring webstore.2View comments

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. There is a reason for this - DNG 1.3 allows for opcodes, which Leica use for lens correction.
- In the DNG I looked at, which was shot with a "Summicron TL 1:2 23 ASPH." lens, lens correction is done by a single "WarpRectilinear" operation in the DNG.
- In addition to the lens correction op code, there is also a "FixBadPixelsConstant" opcode, whose function is exactly as the name states. This is the same as in the Leica Q, SL, etc.
- Unusually, the DNGs all contain 2 different JPEG preview images in addition to the main raw image, one of 1620x1080, and finally a full sized preview of 6000x4000. Having the full sized preview is particularly odd, as it takes up a lot of space. In the approximately 45 MB files I've seen, the full size preview typically takes up about 1.8 MB.
So in summary, the DNGs appear to be a bit of a hybrid of the "SL", "Q", etc style of DNG, with a single lens correction opcode, and a bad pixels correction opcode, and of the "M10" style of DNG, with a full sized preview. As I noted in my analysis of the M10 DNG, the full size preview is probably there to support viewing on mobile devices that often don't have raw decoding capability built in.Finally, it's notable that the DNGs don't contain the bizarre Lightroom XMP metadata that the M10 DNGs have embedded in them.2View comments

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.

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. At the time, I wrote that just by eyeballing the published images, I believed the improvement to be "closer to 0.5 stops than 1.5-2".
Much to my surprise, given what I had thought to be just a basic explanation of why dynamic range is a tricky concept, the post generated a lot of push-back. And I mean a LOT.
Well, now there is actually an independent third-party measurement available, from photonstophotos.net:
And....(drum roll)....the improvement in DR between the M240 and the M10 is 0.55 stops. As I predicted back in January.
You can a find whole lot more information, including a useful interactive graphing tool that allows you to compare cameras, on the photonstophotos.net site.0Add a comment

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.
dcpTool allows you to:
- Decompile DNG Camera Profile (DCP) files in XML. The XML can then be read and edited with a simple text editor.
- Recompile edited XML into DCP files
- Remove "Hue twists" from camera profiles.
For more information on hue twists, see these posts:11View comments

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". Lens corrections also have some downsides:
- Lens corrections result in a small reduction in sharpness. Sean Reid, at Reid Reviews has done extensive testing on this as part of his various lens reviews, and his conclusions are clear - there is a measurable loss in sharpness.
- Lens corrections result in some reduction in image size - the corrections inevitably result in the edges of the image curving, and the curved parts need to be trimmed off to get back to a straight edge.
So sometimes, it's useful to be able to get an uncorrected image. Now there are some raw developer apps that allow you get to uncorrected images (AccuRaw EXR is one of them), but most mainstream apps such as Lightroom and Photoshop don't allow correction to be disabled.Fortunately though, there is a "simple trick" that will allow you to disable lens corrections for nearly any camera that produces raw images. What you need to do is a simple two step process:- Firstly, convert the raw image to a DNG image, using Adobe's DNG converter.
- Then use DNG Cleaner (macOS only) to remove any opcodes.
The resulting DNG will not have any lens correction, and you can load it into Lightroom, Photoshop, or any other app that supports DNGs.Why does this work? This works because whenever DNG Converter converts an image that needs lens correction, it embeds the required correction as an "opcode" into the DNG image. Lens correction opcodes as usually things like "WarpRectilinear". DNG Cleaner knows where to find these opcodes, and simply removes them, as long as you have the "Remove opcodes" checkbox selected:
Note that in order for this to work, you need DNG converter to be using it's default settings. Specifically, Compatibility should be set to the most recent version of Camera Raw. You should definitely not be using Custom Settings with the "Linear" checkbox selected. "Linear", otherwise known as LinearRaw, bakes any corrections into the actual data in the DNG, making it impossible to remove.
There's more information on the DNG Cleaner website.0Add a comment

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). For M10 DNGs this will remove:
- The full size image preview - that will save about 3MB
- The various Lightroom/Photoshop adjustments embedded in the XMP portion of the DNG - ISO dependent noise reduction settings, lens profiles, etc
DNG cleaner will also optionally remove opcodes, and apply lossless compression. This isn't relevant to the M10, but in many other Leica cameras, e.g., the Q, the SL, etc, opcodes are used for lens correction. For an example of the SL's with and without lens correction, see my post on the subject. DNG Cleaner is what Sean Reid used to remove opcodes for his SL 50 review, which some of you will have seen.
As ever, back up your files before using any app that is designed to modify them.
For more information on DNG Cleaner, see the website.0Add a comment

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. AccuRaw has always been focussed on having highly linear color response, with no "hue twists" or other surprises in the color rendering. As it turns out, that is a very useful feature to have if you're composting stills into video - it reduces the amount of work required for color matching.
In the world of video, especially in the professional cinematography world, the "gold standard" is to use a format such as EXR, which is a floating point format. That allows huge flexibility in the way that post processing is done. So the new version of AccuRaw, now named AccuRaw EXR, supports EXR output.
However, it's more than just a name change. In order to really support EXR output, AccuRaw has seen major changes internally - it now has a fully floating point, non-clipping workflow. For more on why that is important, see this post.
