AccuRaw EXR is a raw image editor and developer that offers ultra high resolution, linear processing and a non-clipping workflow, ideal for integration with video in complex post processing environments.

Raw file formats from most camera manufacturers are supported, for example Nikon NEF files, Canon CR2 files, Leica DNG files, etc. AccuRaw also provides state-of-the-art processing for Fuji X-Trans based cameras. A full list of supported cameras is on the product web site.

AccuRaw EXR Features
• Non-clipping workflow - Accuraw EXR has a highly linear floating point processing engine that treats EXR as a first-class citizen. You can easily recover even heavily blown highlights in downstream processing apps.
• EXR is a first-class citizen - AccuRaw offers the choice of 16-bit or 32-bit and either RBG or RGBA output.
• Optimized to maximize image resolution.
• Precise control over demosiacing. Most raw developers give you one choice about how your image is developed - soft images with no risk of artifacts. AccuRaw allows you control over the internal operation of the demosaicing engine. Maximum resolution or maximum suppression of artifacts such as moire, or anywhere in-between. The choice is yours.
• Accurate, calibrated color workflow. Color not the way the remember seeing it? Tired of "content aware processing" and "hue twists" taking decisions away from you? Want your starting point to be what the camera saw, not "enhanced colors"? AccuRaw has a 100% accurate color workflow end to end, and lets you explicitly select whether or not to use tone curves, highlight preservation, etc, etc. And of course, AccuRaw supports industry standard DCP (DNG camera profile) camera calibration files as produced by software from many vendors.
• Fits with your workflow. AccuRaw doesn't try to take over your workflow. It just fits in. There are no catalogs to worry about; your files stay right where they are, and AccuRaw never touches them. AccuRaw just automatically remembers your edits. A powerful system of presets and batch processing make work efficient, and you can output to any of JPEG, TIFF, EXR or DNG for maximum compatibility with your choice of post processing and digital asset management tools.
• Integration with apps such as Lightroom, Photoshop and Aperture
• macOS High Sierra and Retina display compatible

** Note: AccuRaw doesn't do noise reduction or lens corrections - the image you get is the image your camera saw.

System Requirements:

Raw conversion requires very substantial amounts of processing power and memory. While AccuRaw will run on laptops, performance is optimized for desktop systems. We strongly recommend the following minimum system specifications:
• OS X 10.7 (Lion) or later
• 4 GB system memory minimum, 16GB recommended
• 128 MB graphics memory minimum, 512 MB graphics memory recommended

What’s New

Version 3.1.1

• Enhanced dark mode support under macOS Mojave
• Fix for an issue that could result in the EXR export menu not appearing under macOS Mojave

Great Detail!

I have been able to get more detail out of my raw files with this program that several others, including lightroom and DXO Photolab. Great program thats simple to use. In my orginal review I had complained about the hightlight and shadow recovery, that has now been fixed. Truly a very effective RAW converter!

Developer Response ,

Thanks; we're glad that AccuRaw EXR is working well for you. We'll be looking at improving highlight and shadow recovery in a future version.

Amazing detail

OMG! I just compared this, using a .NEF from my D800, with Capture One Pro, DxO 11,and Lightroom CC. Looking only at accurate detail, Accruraw blew them ALL away ! Simply no comparison. Sigh... now I have to adjust my carefully crafted workflow again.

Now, to be fair, Accuraw has -none- of the presets, gizmos and doohickies of all the others, and admittedly some of those are extremely useful. But, if my tests are right this is a tradeoff I'll happily make for the exquisite fundamental image Accuraw produces.

Fantastic work, Alexander. Sweet.

So far, unusable

I've got a 27' 2010 iMac with all the required specs and software updates. This program hangs each and every time I've opened it and is basically unusable. There is a chance of course that it is conflicting with other software, but as this happens so rarely on Apple machines, I'm tempted to just say this is in no way ready for primetime and qualifies as the first product I've bought on the App Store that I will ask for my money back.
