SRW vs HDR Format Comparison

Aspect	SRW (Source Format)	HDR (Target Format)
Format Overview	SRW Samsung RAW Image Format A proprietary RAW image format used by Samsung NX series mirrorless cameras. SRW files contain unprocessed sensor data with 12-bit or 14-bit color depth from Samsung's APS-C CMOS sensors. The NX camera line was discontinued in 2015, making SRW a legacy format with valuable archived captures. RAW Lossless	HDR Radiance RGBE High Dynamic Range A high dynamic range image format created by Greg Ward in 1985 for the Radiance lighting simulation system. HDR uses 32-bit floating-point values per channel to store luminance data that far exceeds the range of standard 8-bit images, capturing the full spectrum of visible light from darkest shadows to brightest highlights. Standard Lossless
Technical Specifications	Color Depth: 12-bit or 14-bit per channel (RAW) Compression: Lossless compressed RAW Transparency: Not supported Sensor: Samsung APS-C CMOS (Bayer pattern) Extensions: .srw	Color Depth: 32-bit float per channel (RGBE encoding) Compression: Run-length encoding (RLE) Transparency: Not supported Animation: Not supported Extensions: .hdr, .pic
Image Quality	12/14-bit RAW sensor data with full detail Samsung APS-C sensors with good resolution Wide dynamic range from unprocessed capture Full white balance and exposure editing latitude	32-bit float per channel captures extreme luminance range Dynamic range exceeds 76 orders of magnitude RGBE encoding preserves highlight and shadow detail Suitable for physically accurate lighting data
Processing & Tools	Process SRW files with RAW software: # Using rawpy (Python) import rawpy raw = rawpy.imread("photo.srw") rgb = raw.postprocess() # Using dcraw dcraw -T -4 photo.srw # Adobe Lightroom # Open SRW directly for editing	Work with HDR files using imaging tools: # View HDR with ImageMagick magick display input.hdr # Convert with OpenCV (Python) import cv2 img = cv2.imread("input.hdr", cv2.IMREAD_ANYDEPTH) # Radiance tools ra_xyze -r input.hdr output.hdr

Why Convert SRW to HDR?

Converting SRW (Samsung RAW) to HDR (Radiance RGBE) gives new life to your Samsung NX camera archives by transforming them into high dynamic range files compatible with modern 3D rendering and visualization software. Since Samsung discontinued the NX camera line in 2015, SRW files represent a legacy format with declining software support, making conversion to HDR a practical preservation strategy.

Samsung NX cameras, particularly the NX1, produced excellent image quality with their APS-C sensors. The 12/14-bit RAW data in SRW files contains valuable tonal information that maps well to HDR's 32-bit floating-point space, creating environment maps and lighting references suitable for professional CG work.

This conversion ensures that your Samsung NX photography remains accessible and useful in modern workflows, whether for 3D rendering, architectural visualization, or HDR display output. The HDR format enjoys universal support across 3D applications that SRW lacks.

Our free online converter handles the SRW to HDR transformation seamlessly, processing the Samsung RAW sensor data and outputting properly encoded Radiance RGBE files. Simply upload your SRW file and download the converted HDR result instantly.

Key Benefits of Converting SRW to HDR:

Archive Preservation: Convert discontinued Samsung NX files to a supported format
HDR Precision: 12/14-bit RAW data mapped to 32-bit floating-point HDR space
3D Rendering Ready: HDR output works in Blender, Maya, Unity, and Unreal Engine
Future-Proof: HDR format has broader and more active support than legacy SRW
Environment Mapping: Create IBL probes from Samsung NX photography
No Software Required: Convert directly in your browser with no installation needed
Instant Processing: Fast conversion with immediate download of the result

Practical Examples

Example 1: Samsung NX1 Archive to 3D Environments

Scenario: A photographer has travel panoramas shot with a Samsung NX1 and wants to create HDR environment maps for a virtual tour project.

Source: SAM_0847.SRW (32 MB, 6480x4320px, 14-bit)
Format: Samsung SRW RAW, NX1 APS-C sensor
Camera: Samsung NX1, 16-50mm f/2-2.8

Result: SAM_0847.hdr (32-bit float environment map)

Workflow:
1. Retrieve NX1 SRW panoramas from archive
2. Convert to HDR for environment mapping
3. Use in Unity for virtual tour lighting
* NX1's excellent sensor quality preserved
* 14-bit data maximizes HDR quality

Frequently Asked Questions (FAQ)

Q: What is SRW format?

A: SRW is Samsung's proprietary RAW image format used by their NX series mirrorless cameras. It stores 12-bit or 14-bit unprocessed sensor data from Samsung's APS-C CMOS sensors. The format was discontinued along with the NX camera line in 2015.

Q: Will I lose quality converting SRW to HDR?

A: No. The 12/14-bit RAW data is demosaiced and mapped into HDR's 32-bit floating-point space, preserving all original sensor detail and tonal range from the Samsung NX capture.

Q: Which Samsung cameras produced SRW files?

A: SRW files were produced by the Samsung NX series, including the NX1, NX500, NX300, NX30, NX210, NX200, NX100, NX10, and other NX-mount cameras. The flagship NX1 (2014) was the last major model before discontinuation.

Q: Is SRW format still supported by modern software?

A: Adobe Lightroom, Capture One, darktable, and rawpy still support SRW, but since Samsung discontinued the format, future support is not guaranteed. Converting to HDR ensures long-term accessibility.

Q: Is converting SRW to HDR free?

A: Yes! Our online converter transforms SRW files to HDR completely free with no registration, no watermarks, and no file count limits. Simply upload your SRW file and download the converted HDR.

Q: Can I use the HDR output in game engines?

A: Yes, HDR files converted from SRW are fully compatible with Unity, Unreal Engine, and other game engines for environment maps, skyboxes, and image-based lighting.

Q: What are the file extensions for HDR?

A: Radiance HDR files use the extensions .hdr and .pic. Both contain RGBE-encoded floating-point data and are interchangeable across all compatible applications.

Q: Can I batch convert multiple SRW files?

A: Yes, you can upload and convert multiple SRW files simultaneously. Batch conversion is ideal for migrating entire Samsung NX photo archives to HDR format.
