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.

Best app for opening my big Olympus raw files!

Currently, one of my favorite photo apps.
It opens AND saves BIG files. I had to play with the sharpness settings before I got good results. I am using a 3rd Gen. Retina iPad. Yes, it takes awhile...but it opens the 80MP Olympus E-M1 Mark II High Resolution Raw files! Amazing. There are some quirks, but it works. I also often use PhotoGene, which is a great and more full featured app, but this has its strengths. I sincerely hope it is further developed, and thank you to the creators!

BTW: Study the description and screen shots BEFORE you buy. What you see, is what you get. Check the developer's site, because there's lots of documentation, helpful tips and information there to help you make an informed decision. If you make a mistake, is it right to blame someone else?
