I previously wrote about a nasty bug in iOS 8 that prevented PhotoRaw from accessing any images that were shot as raw+JPEG.
Apple haven't fixed the bug - indeed, they have shown no interest at all in either fixing it or providing a workaround - but I'm pleased to say that as of version 4.2.0 of PhotoRaw, this shouldn't be a problem anymore. I've rewritten a large portion of PhotoRaw's image importing code to use an entirely different mechanism for importing under iOS 8. Of course, that mechanism doesn't exist under iOS 7 and earlier, so PhotoRaw now has a separate code path for iOS 8.
The version of PhotoRaw with the fix is on the App Store now, and a fixed version of PhotoRaw Lite will also be there as soon as Apple approve it.

While Adobe's DNK SDK has been a great asset for the imaging world, allowing all sorts of useful open source software, including my CornerFix and dcpTool packages, as written it only supports Windows and OS X. This is for good reason - Adobe is a commercial organization, and the vast majority of software for commercial use is one of either Windows or OS X. So there wasn't much point in Adobe spending a lot of time and energy getting the SDK running on Linux.
Fortunately, there are folks that are willing to take on challenges like this. "Cellstorm" has documented how to get dcpTool up and running on Linux in an article: DNG tools in Linux. This ported version can be used with Elle Stone's dcraw-float package. The dcraw-float package has a number of improvement relative to the base version of dcraw, including the ability to use DNG camera profiles.1View comments

So you can stop emailing me :)
The versions of AccuRaw and AccuRaw Monochrome on the App Store as of this morning (V2.2.8) have support for the Canon 7D Mark II, Canon SX60 HS, Canon G7 X and Fuji X100T.
PhotoRaw will also have support for all those cameras in a few days; this time round PhotoRaw is lagging by a few days because of some user interface tweaks to better support the iPhone 6 and 6+.

Erik Kaffehr just posted a short comparative mini-review of four raw developers - AccuRaw, Lightroom, Capture One and RawTherapee.
Erik's focus in the mini-review was primarily on demosaicing performance using an image from a Phase One P45 medium format back, but there's also some discussion of color rendering.
Given that the P45 is a Phase One product, you'd expect Phase One's Capture One product to sweep the field, but not so. The review is well worth the read if you're interested in how various raw converters behave with "difficult" images.

Updated: It's now safe to update; Apple have not fixed the bug, and show no signs of ever doing so, but as of version 4.2.0, PhotoRaw has a workaround.
For those of you that are PhotoRaw users, I'd recommend not updating to iOS 8 just yet.
There is a significant bug in iOS 8 that will prevent PhotoRaw from importing images that were shot as raw+jpeg. The details are as follows:
- If you import an image from an SD Card onto an iOS 8 device that was shot as raw+jpeg (so there is an xxxx.raw and xxxx.jpg file present), the import operation onto the device will go fine.
- However, when you try to open the raw file in PhotoRaw, you'll get an error.
- What is happening is that despite the raw file being present on the device, and PhotoRaw correctly asking for the raw file, iOS 8 only ever provides the jpeg file to any apps that request it.
The only know fix for this that I'm aware of right now is to shoot raw only (or use iOS 7!). If only a raw file is on your device, iOS will correctly provide that to PhotoRaw, and the import operation will be fine.I'm in contact with Apple on this issue, but so far they have only said that they will get back to me "when an engineer is assigned to the bug". Which given the number of other bugs in iOS 8, may take a while.So, if you have the choice, and shoot raw+jpeg, you should hold off on updating to iOS 8.I'll update this post when the issue is fixed.
Updated: This bug is not fixed in iOS 8.1.0. If you're not happy with this, please email Tim Cook, asking him to fix bug #18581425
Updated again: This bug is also not fixed under iOS 8.1.1.0Add a comment

I've received several emails asking about the status of support for the new Nikon D750. Here is the state of play: the latest versions of both AccuRaw and AccuRaw Monochrome on the App Store have D750 support already. The version of PhotoRaw with D750 support is complete, and already with Apple - it should be available on the App Store in 4-5 days.
The new versions also have support for the new Leica cameras - the Leica M-P, Leica M-60, Leica X (Type 113) and Leica S (Type 007).0Add a comment

AccuRaw and AccuRaw Monochrome 2.2.1 for the Mac are now available on the Apple App Store. There was a bit of delay between the availability of the PhotoRaw version that supports these cameras and the AccuRaw version (due to Apple having a sudden fit of insanity around some the technicalities of a particular app entitlement). But it's out now - version 2.2.1 adds raw image support for new cameras including the Nikon D810, Nikon 1 J4, Nikon 1 S2, Panasonic DMC-FZ1000, Sony Alpha 77 II and Sony Alpha A7S. Enjoy!0

I just took a quick look inside a DNG from one of Leica's new Leica T cameras:
- The camera firmware version number shows as "1.02", so what should be production firmware.
- The camera name shows as "Leica T (Typ 701)"
- The image data is 12-bit. There is no compression used in the DNG I looked at. Somewhat unusually, the data is appears to be packed, four 12-bit values in 6 bytes, rather than the more typical one 12-bit value in a 16-bit location. This is allowed by the DNG spec, but isn't often used. This means that the file size is approximately 24.5 MB vs. what would otherwise be approximately 33.6 MB.
- The DNG version is 1.3, a higher revision that that the 1.1 that most previous Leica cameras have used. 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 18-56 Vario-Elmar lens, lens correction is done by a single "WarpRectilinear" operation in the DNG. Other lenses (or the same lens at a different focal length), might use other codes.
- There is a single Leica makernote.
Generally, the DNG seems to be quite standard - it happily works with current versions of all of my software - PhotoRaw, AccuRaw, AccuRaw Monochrome and Cornerfix "out of the box".
The only slightly interesting thing I noticed is the color rendering in the DNG. When I looked at Sean Reid's images in his review of the camera, I commented to him that the colors looked over saturated, especially the reds. Interesting, looking at a DNG alongside a JPEG preview, the JPEG preview is much more subdued than a DNG rendering using the Leica embedded color profile, especially in the reds. However, this is probably nothing that couldn't be fixed with a custom camera profile.4View comments

A lot of people have found out that, contrary to what they might have assumed, you can't import raw files into Lightroom Mobile on the iPad. Only JPEGs are supported. To import raws, you need to go via a desktop machine. Which is not much use if you're in the field with only an iPad.
Fortunately, there an easy work-round with PhotoRaw - here's the step-by-step instructions:
- Install PhotoRaw on your iPad. Note that PhotoRaw Lite won't work for this.
- Import the raw files stored on your iPad into PhotoRaw.
- Batch export them - touch the batch button (the gears), select all the files, then touch the action button (the arrow), select JPEG quality, and touch save.
- Your images are now saved on the iPad as JPEG at full resolution, and can be imported into Lightroom Mobile just as you would any other JPEG
