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 16 mega-pixel plus images such as from a Nikon D3x or a Leica M9.
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, e.g., Canon 5DII and 7D 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.
PhotoRaw Lite has just been updated and now has support for the Canon EOS 650D, Fuji FinePix HS30EXR, FinePix F770EXR, Sony DSC-RX100, Sony NEX-F3 and Sony SLT-A37.
