The iOS 8 raw+jpeg bug is fixed

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.

dcpTool and the DNG SDK on Linux

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.

AccuRaw support for the Canon 7D II, SX60 HS, G7 X and Fuji X100T

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+.

Mini Comparative Review of AccuRaw, Lightroom, Capture One and RawTherapee

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.

Don't update to iOS 8

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:
  1. 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.
  2. However, when you try to open the raw file in PhotoRaw, you'll get an error.
  3. 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.

Nikon D750 support for AccuRaw and PhotoRaw

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).

AccuRaw and AccuRaw Monochrome 2.2.1 - Nikon D810, Sony A7S, A77 M2, etc support

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!
