PhotoRaw for iOS is a viewer and developer for image files in raw format. Raw file formats from most camera manufacturers are supported, for example Nikon NEF files, Canon CR2 files, Leica DNG files, etc - see the product web site for a full list of supported cameras. PhotoRaw allows you to view these files at full 1:1 pixel resolution, even 100 mega-pixel plus medium format images.

PhotoRaw implements virtual memory. Virtual memory means that if PhotoRaw runs low on physical RAM because of other apps running the background, it can use the device's flash memory to process even the largest images. PhotoRaw has been tested with images of up to 72 MPixels on both iPads and iPhones, even with multiple other apps running the background.

Most images viewers for the iPhone, iPad and iPod Touch are only able to display low resolution thumbnails of raw images, making it difficult to use the iPhone or iPad to evaluate and view raw files in the field. PhotoRaw changes all that. PhotoRaw incorporates a state-of-the-art AHD raw image demosaicing algorithm right into an iOS app. So now you can view every single pixel in a raw file, without needing a desktop machine or laptop.

To ensure that you see your images in a form as close as possible to what you'll see using a full featured desktop raw developer program such as Aperture, PhotoRaw incorporates a full demosaicing engine, as well as basic exposure controls such as exposure, contrast and brightness. You can even control sharpening to make sure that the image looks its best.

You can also export images, or cropped portions of images, from PhotoRaw in JPEG or TIFF format. So you can email a processed, cropped JPEG to clients or friends right from your iPad or iPhone.

· PhotoRaw supports only raw formats; JPEG, TIFF etc images are not supported
· Importing large raw files can take up to several minutes, especially if other apps are running in the background

System Requirements: Raw conversion requires very substantial amounts of processing power and memory. We strongly recommend the following minimum system specifications:
· iOS 8 or later
· iPad or iPhone 4 or later

Raw Conversion and Simplicity

I'm a semi-pro photographer and shoot in RAW format 99% of the time. Currently I use Apple's Aperture for my RAW conversion and post processing. Although I find Aperture an excellent photo processor, it can be a little confusing at times with all of its capabilities. I saw this app while browsing the app store and decided to download after reading the developers web site. I was pleased to find it did what is advertised and does it well. Further, it is very simplistic to use and gets down to the basics of post processing. I wish it had an histogram view but not a major issue, just would be a little helpful.
Performance is not bad but be prepared to wait a little during up loads. The controls are good but can be hard to make very minor changes with the sliders (a little tweaking could fix this), should be just a little smoother but, again not a major issue.
For basic post processing work it is excellent; easy to use, all of the basic adjustments are available. I use this app in the field for quick post processing on my New IPAD, then up load into my MAC Mini or MAC PRO to use Aperture for extra fine detail work, then print or save to JPEGs.

This app will get a lot use during my photo sessions. Nice job! Recommend to any photographer shooting RAW format.

Outstanding customer service

I reported a problem via email and they immediately responded. Together we diagnosed the problem and they had a fix in place within 24 hours. Now that’s customer service!

Desktop quality decoding, interface needs work

This app decodes my Canon RAW files better than Filterstorm, Photogene, or PiRAWnha—the images are appreciably sharper, more detailed, somewhat less noisy, and have superior dynamic ranges, most of the time. It's the one RAW decoder app that consistently delivers the advantages of working with RAW files and without much more latency than I'm used to running Aperture on my i5 MacBook Pro.

On my iPhone 5S, it's impressively fast—batch import/export ends up being very useful. In terms of workflow efficiency, the problem is the user interface needs work: sliders are hard to move accurately, there's no ability to save or load presets, etc.

With a little bit of polishing, this app could be a game changer for photojournalists on the go. I can't wait for the day this thing is able to import a batch of files, apply a little bit of processing to them, and dump them into Photogene.
