ORF vs ICO Format Comparison
| Aspect | ORF (Source Format) | ICO (Target Format) |
|---|---|---|
| Format Overview |
ORF
Olympus RAW Format
Olympus's proprietary RAW image format used by OM-D and PEN series cameras. ORF files contain unprocessed sensor data with 12-bit bit depth, capturing full dynamic range and color information for maximum post-processing flexibility. RAW Lossless |
ICO
Windows Icon
A container format for small raster images used as application icons, file type icons, and website favicons. ICO files can store multiple image sizes (16×16 to 256×256) and color depths in a single file, allowing the OS to select the best resolution for each context. Modern ICO files embed PNG-compressed images for sizes 256×256 and above. Legacy Lossless |

| Processing & Tools |
ORF processing and conversion tools: # Convert ORF to JPG with dcraw
dcraw -c -w input.orf | magick - output.jpg
# Convert ORF using rawpy (Python)
import rawpy
raw = rawpy.imread("input.orf")
rgb = raw.postprocess()
|
ICO creation with multiple resolutions: # Convert image to ICO with multiple sizes
magick input.png -define icon:auto-resize=256,128,64,48,32,16 output.ico
# Convert to single-size ICO
magick input.png -resize 256x256 output.ico
# Create ICO with Pillow (Python)
from PIL import Image
img = Image.open("input.png").convert("RGBA")
img.save("output.ico", format="ICO", sizes=[img.size])

Why Convert ORF to ICO?
Converting ORF to ICO enables you to create application icons and website favicons directly from Olympus camera RAW files. When you need pixel-perfect icons derived from professional photography — product shots, brand imagery, or visual assets — starting from RAW ensures the highest possible source quality.
Olympus ORF files contain 12-bit of color data per channel, providing extensive editing range before conversion. You can precisely adjust exposure, color balance, and contrast to achieve the perfect icon appearance before downscaling to ICO’s 256×256 maximum resolution.
The high resolution of Olympus camera files (typically 20–60+ megapixels) provides far more detail than ICO requires. This abundance of source data means the downscaling algorithm can make optimal decisions about which details to preserve, resulting in sharper, cleaner icons than starting from a lower-resolution source.
Note that ORF files are demosaiced automatically during conversion, applying default processing. For best results with critical icon designs, process the ORF in a dedicated RAW editor (Lightroom, Capture One) first, then convert the optimized result to ICO format.
Key Benefits of Converting ORF to ICO:
- Maximum Source Quality: 12-bit sensor data provides the best starting point for icons
- High Resolution: Olympus cameras provide abundant detail for crisp icons at all sizes
- Color Accuracy: RAW color data enables precise color matching for brand icons
- Transparency Support: ICO’s alpha channel enables transparent icon backgrounds
- Multi-Resolution: High-res source ensures quality icons from 16×16 to 256×256
- Professional Pipeline: Direct camera-to-icon workflow for product imagery
- Favicon Creation: Generate website favicons from professional Olympus photography
Practical Examples
Example 1: Product Icon from Olympus Camera Photo
Scenario: A software company photographs their product with a Olympus camera to create a photo-realistic application icon.
Source: product.orf (12-bit, Olympus OM-D and PEN series) Conversion: ORF → ICO (multi-resolution) Result: product_icon.ico (45 KB, 256/128/64/48/32/16px) Workflow: 1. Photograph product in ORF RAW format 2. Process: adjust exposure, white balance, crop to square 3. Convert to ICO with all standard icon sizes ✓ Photo-realistic icon from actual product photography ✓ Crisp detail at every size from high-res source ✓ Professional branding consistency
Example 2: Website Favicon from Brand Photography
Scenario: A business creates a website favicon from a brand photo shot on a Olympus camera.
Source: brand_logo.orf (12-bit, Olympus RAW) Conversion: ORF → ICO (favicon sizes) Result: favicon.ico (8 KB, 48/32/16px) Benefits: ✓ Maximum color accuracy from RAW source ✓ Sharp details preserved at 16×16 favicon size ✓ Professional appearance in browser tabs ✓ Compatible with all web browsers
Example 3: Desktop Shortcut Icon from Nature Photo
Scenario: A photographer creates custom desktop shortcut icons from Olympus landscape photographs for a themed desktop setup.
Source: sunset.orf (12-bit, Olympus RAW) Conversion: ORF → ICO (desktop icon) Result: sunset_icon.ico (52 KB, 256/128/64/48/32/16px) Custom desktop workflow: ✓ RAW processing maximizes color vibrancy ✓ Full 256×256 icon for Windows desktop display ✓ Multiple sizes for consistent rendering ✓ Personal photo icons for folder shortcuts
Frequently Asked Questions (FAQ)
Q: Will the full ORF quality be preserved in the ICO?
A: ICO is limited to 256×256 pixels and 32-bit color. The ORF’s 12-bit data will be downscaled, but starting from RAW ensures the best possible icon quality through superior downscaling from a high-resolution source.
Q: Should I process the ORF file first?
A: For best results, process in a RAW editor (Lightroom, Capture One) first. Default RAW processing works but may not match your creative vision. Pre-processing is especially important for icons where visual impact matters at small sizes.
Q: How large will the ICO file be?
A: ICO files typically range from 20–100 KB with PNG compression. This is dramatically smaller than source ORF files (20–60 MB) due to downscaling and compression.
Q: Can I create a transparent icon from ORF?
A: ICO supports transparency, but ORF RAW files don’t contain alpha data. Convert to PNG first, remove the background with an image editor or AI tool, then convert to ICO for transparency.
Q: What icon sizes does the converter create?
A: The converter creates a single ICO at up to 256×256. For multi-resolution ICOs with all standard sizes, use ImageMagick’s icon:auto-resize option or a dedicated icon editor.
Q: Will EXIF data from my Olympus camera be preserved?
A: No. ICO does not support EXIF metadata. Camera settings, GPS, and Olympus MakerNote data are discarded. Keep the original ORF file for metadata preservation.
Q: Can the ICO be used as a website favicon?
A: Yes. Place the file as favicon.ico in your website root. ICO is supported by every browser including legacy IE versions, making it the most compatible favicon format.
Q: Is ORF to ICO conversion reversible?
A: No. The conversion reduces resolution to 256×256 max and color depth to 8-bit per channel, discarding all RAW processing flexibility. Always keep original ORF files.
