About formats

DNG (Digital Negative) is an open, royalty-free RAW image format published by Adobe Systems on September 27, 2004, designed to address the proliferation of incompatible proprietary RAW formats from different camera manufacturers. Based on the TIFF/EP standard (ISO 12234-2), DNG provides a well-documented container for raw sensor data with standardized metadata tags that describe the camera's color filter array pattern, color calibration matrices, default rendering parameters, and opcodes for geometric corrections. The format supports both original raw mosaic data and linear (demosaiced) DNG, as well as lossy DNG using JPEG compression for smaller archive sizes when full quality is not critical. Adobe has iterated the specification through multiple versions, adding support for transparency maps, floating-point HDR data, enhanced color profiles, and semantic masks in newer revisions. One advantage is archival reliability — DNG's published, non-proprietary specification eliminates the risk that a camera manufacturer's format becomes unreadable when that company exits the market or drops support for older models, a concern that motivated Adobe's creation of the format. The format also enables embedded original RAW data, letting users convert their CR2, NEF, or ARW files to DNG while optionally keeping the original bits inside the DNG for reversibility. Broad ecosystem support is another strength: Adobe Lightroom, Photoshop, and Camera Raw treat DNG as a first-class format, and many smartphone manufacturers (including Google and Apple for certain modes) output DNG natively.

SUN is a raster image format associated with Sun Microsystems workstations, encompassing both the Sun Raster format (.ras) and the Sun Icon format used for window system icons and cursors on SunOS and Solaris systems. Sun Raster files, identifiable by their 0x59a66a95 magic number, store bitmap images in 1-bit monochrome, 8-bit indexed color, 24-bit BGR, or 32-bit XBGR modes, with optional run-length encoding compression and a 32-byte header. The Sun Icon subset is a simpler text-based format used for small monochrome bitmaps — window icons, cursor images, and toolbar graphics — stored as C-language data arrays that could be directly compiled into X Window and SunView applications. These icon files begin with a comment block specifying width, height, and optionally hot spot coordinates (for cursor images), followed by hexadecimal pixel values in a format readable by both the C compiler and the iconedit tool. Sun workstations running SunOS and later Solaris were foundational platforms for Unix computing, networking, and the early internet, and the SUN image formats were integral to their graphical environments. One advantage is the format's dual text/binary nature: Sun Icons are valid C source code that can be #included directly into applications, a practical approach to resource embedding that predates modern asset management systems. The Sun Raster variant's simplicity provides another strength — the 32-byte header and straightforward encoding make it one of the easiest binary image formats to parse. SUN format files are supported by ImageMagick, GIMP, XnView, and Unix image viewing tools.

Frequently Asked Questions

Why convert DNG to SUN?

SUN is a Sun/Oracle workstation image format. Converting from DNG produces images compatible with Solaris and Unix imaging environments.

What programs open SUN?

Programs that handle SUN include Sun/Oracle tools, GIMP, IrfanView, and XnView.

Are DNG and SUN the same quality?

DNG stores raw sensor data while SUN is a processed format. The conversion produces the best quality SUN can support from your original RAW data.

Will my DNG metadata (EXIF) be preserved?

Metadata handling depends on the target format. Where SUN supports it, camera data like shooting parameters and GPS coordinates can be retained.

Does this work with all camera models?

The converter supports DNG from all camera models that produce this format — whether you shoot with an entry-level body or a professional flagship.
