|---|---|---|
| Format Overview |
SRW
Samsung RAW File

| Processing & Tools |
SRW requires RAW processing software to demosaic Samsung's sensor data into viewable images.
# dcraw processing
dcraw -T -6 photo.srw
# Python rawpy
import rawpy
raw = rawpy.imread('photo.srw')
rgb = raw.postprocess(output_bps=16)
|
EXR is natively supported by all professional VFX, compositing, and 3D rendering tools.
# OpenEXR command-line tools
exrinfo image.exr
exrheader image.exr
# Python OpenEXR
import OpenEXR, Imath
exr = OpenEXR.InputFile('image.exr')
header = exr.header()

Why Convert SRW to EXR?
Converting SRW to EXR is critical for preserving Samsung NX camera photographs in a future-proof format. With Samsung having exited the camera market in 2016, software support for SRW is declining, making conversion to the industry-standard EXR essential for long-term accessibility.
The Samsung NX1's 28 MP BSI sensor produced excellent 14-bit RAW data that deserves preservation in a format with guaranteed longevity. EXR's open specification and broad VFX industry adoption ensure these captures will remain accessible for decades.
For photographers integrating Samsung NX captures into modern production workflows, EXR provides the floating-point precision and linear color space that connects legacy camera data to contemporary VFX, HDR, and compositing tools.
EXR's 32-bit float representation provides virtually unlimited editing headroom for rescuing and enhancing Samsung NX photographs, far exceeding what 8/16-bit integer formats can offer for exposure recovery and color grading operations.
Key Benefits of Converting SRW to EXR:
- Future-Proof Archival: Open standard replacing declining SRW support
- 32-bit Float Precision: Unlimited editing headroom from Samsung's 14-bit data
- VFX Pipeline Native: Direct integration with all modern production tools
- Efficient Compression: PIZ/ZIP reduce storage versus raw sensor data
- Linear Color Space: Scene-referred data for accurate post-processing
- Long-Term Preservation: Industry-backed format with guaranteed support
- Modern Tool Access: Opens in Nuke, Blender, Photoshop, DaVinci Resolve
Practical Examples
Example 1: Samsung NX1 Archive Preservation
Scenario: A photographer converts their Samsung NX1 portfolio to future-proof EXR before RAW software drops SRW support entirely.
Source: nx1_portfolio_001-500.srw (500 files, 28 MP, ~12 GB) Target: nx1_portfolio_001-500.exr (500 files, half-float, ~7 GB) Workflow: 1. Upload batch of Samsung NX1 SRW photographs 2. BSI sensor data demosaiced at full 14-bit quality 3. Convert to half-float EXR with ZIP compression 4. Archive in universally supported format 5. Accessible in all major production software Result: Entire Samsung NX1 portfolio preserved in open standard format before SRW support disappears, with 40% size reduction and float precision.
Example 2: Wedding Photography Recovery and Enhancement
Scenario: A client requests high-quality reprints from a wedding shot on Samsung NX cameras, requiring maximum quality extraction and modern post-processing.
Source: wedding_ceremony_028.srw (28 MP, NX1, 36 MB) Target: wedding_ceremony_028.exr (6480x4320, 32-bit float, ~110 MB) Steps: 1. Upload SRW wedding photograph 2. Full 14-bit sensor data demosaiced 3. Convert to 32-bit float for editing headroom 4. Apply exposure correction and color enhancement 5. Output for large-format printing Result: Full Samsung BSI sensor quality extracted in floating-point format, allowing professional-grade restoration and enhancement for premium reprints.
Example 3: Creative Project from NX Archive
Scenario: An artist uses archived Samsung NX photographs as source material for digital art compositing in Blender.
Source: urban_scene_nx500_017.srw (28 MP, NX500, 32 MB) Target: urban_scene_nx500_017.exr (6480x4320, half-float, ~58 MB) Processing: 1. Upload SRW photograph from NX500 2. Demosaic preserving Samsung color character 3. Convert to half-float linear EXR 4. Import into Blender as compositing element 5. Blend with 3D rendered elements Result: Samsung NX photography integrated into Blender's linear compositing pipeline for creative digital art with accurate color blending.
Frequently Asked Questions (FAQ)
Q: Will Samsung ever resume making cameras?
A: As of 2026, Samsung has not announced any return to the camera market. The NX system was discontinued in 2016. This makes SRW format preservation through conversion to EXR or other standard formats increasingly important.
Q: Are all Samsung NX models supported?
A: Yes. All SRW variants from Samsung NX10, NX20, NX30, NX300, NX500, NX1, and other NX-series cameras are supported in both 12-bit and 14-bit variants.
Q: How urgently should I convert my SRW collection?
A: While current RAW processing software still supports SRW, the format receives declining priority. Converting now ensures preservation while tools remain available. EXR provides guaranteed long-term accessibility backed by the film and VFX industry.
Q: Is EXR the best format for SRW archival?
A: EXR is ideal for VFX and HDR workflows. For general photography archival, DNG or TIFF may be more appropriate. Choose EXR when you need floating-point precision, production tool integration, or HDR capabilities.
Q: Will Samsung color rendering be preserved?
A: The conversion extracts raw sensor data and produces a neutral demosaiced result. Samsung's specific color processing is applied in-camera to JPG output. The full sensor data in EXR allows you to recreate custom color renderings through manual grading.
Q: How large are EXR files compared to SRW?
A: EXR files are typically 1.5-3x larger than compressed SRW due to full RGB float data. With half-float and DWAA compression, sizes are more comparable while providing float precision.
Q: Can I view converted EXR files easily?
A: EXR requires professional software: Nuke, Blender, Photoshop, DaVinci Resolve, or free viewers like mrViewer. For casual viewing, convert to JPG or PNG instead. EXR is designed for production workflows.
Q: Can I batch convert my entire NX collection?
A: Yes. Upload multiple SRW files simultaneously and each is converted individually to EXR. This is the recommended approach for archiving entire Samsung NX photo libraries.
