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

Good Basic Raw Converter.

If you are looking for a good simple RAW converter to use on the road this will do the trick. I can convert my RAW images to Tiff then export them to other apps to finish editing. The app is just a RAW converter and not an editing app. The only area that really needs improvement is highlight and shadow recovery. Otherwise, it is a simple easy to use app that does the job.

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.

Excellent raw converter for its intended purpose

I have used PhotoRaw on an ipad2 for 1 1/2 years to convert Leica M9 DNG and Canon 5D RAW files while traveling. The earlier versions were slow but the current version of PhotoRaw is acceptable in speed on the iPad2 for converting a few RAW photos to email to friends while I'm travelling. Once home, I would use Lightroom to make the final RAW conversions. It does not substitute for Lightroom or Photoshop on a full fledged computer. It is limited by the iPad's limitations,such as inability to calibrate the screen to provide precise color management, the limited processor capabilites, and relatively small amount of RAM. I don't use PhotoRaw for most photos that I take, just the few that my friends would like to see before I return home. Users who complain about the program crashing may want to make sure that other programs running in the background are shut down, in order to free up additional RAM. For someone who takes RAW photos and would like to email (or upload onto social media sites) a few photos while travelling without a full-fledged computer, PhotoRaw provides a solution.
