PhotoRaw 4.6.0

PhotoRaw for iOS serves as a robust viewer and developer for raw image files, supporting a wide range of formats, including Nikon NEF, Canon CR2, and Leica DNG. The application offers impressive features such as:

• 1:1 viewing and adjustment of raw image files, accommodating unlimited image sizes.
• Optimization for iOS 16 and iPadOS 15, with effective multitasking support.
• 64-bit processing capabilities to enhance performance.
• Utilization of AirDrop for exporting images seamlessly.
• Examination of EXIF and GPS data embedded within the images.
• A comprehensive suite of image adjustments with options for JPEG and TIFF exports.
• Pixel magnification up to 1:4 for detailed examination.
• Compatibility with images imported from Eye-Fi cards.

The software distinguishes itself by leveraging virtual memory, allowing it to process large images even when physical RAM is limited due to background applications. Users have reported successful operation with images of up to 72 megapixels on both iPads and iPhones under multitasking conditions.

Compared to most image viewers on iOS devices, which typically only display low-resolution thumbnails, PhotoRaw offers an innovative solution by incorporating a sophisticated AHD raw image demosaicing algorithm. This feature enables users to view each pixel in their raw files without relying on a desktop or laptop setup.

To approximate the experience of using advanced desktop raw development programs like Aperture, PhotoRaw includes a full demosaicing engine alongside essential exposure controls, including adjustments for exposure, contrast, brightness, and sharpening. This functionality ensures that images are presented at their highest quality.

The application also allows users to export processed or cropped images directly in JPEG or TIFF formats, facilitating easy sharing via email or social media directly from mobile devices.

However, there are notable limitations to consider:

• PhotoRaw exclusively supports raw formats; JPEG and TIFF files are not compatible.
• Importing large raw files may take several minutes, particularly if other applications are active in the background.

Given the substantial processing power and memory required for raw conversion, it is advisable to meet the following system specifications:

• iOS 8 or later
• iPad or iPhone 4 or later
