Software (contd.) - RAW conversion

As is normal in our digital SLR reviews I like to compare the supplied RAW conversion software, any optional manufacturer RAW conversion software and Adobe's "Camera RAW" plug-in which is standard with Adobe Photoshop CS. The current version of Adobe Camera RAW has preliminary support for the E-300.

Sharpness and Detail

  • JPEG - Default settings
  • Olympus Master 1.11 - Default settings
  • Olympus Studio 1.2 - High Speed (HS), Default settings
  • Olympus Studio 1.2 - High Function (HF), False Color Suppression: 7
  • Adobe Camera RAW - Sharpness: 50, Color Noise Reduction: 25 (default)

After converting using Adobe Camera RAW it became obvious that the E-300's images would need a little more sharpening (than the default setting of 25) to be close to the output from the camera and Olympus Master we had to use a setting of 50. Overall the best result was obtained using Olympus Studio in High Function mode (slower but better quality). It exhibited the best sharpness, most neutral color and no demosaic artifacts. Crops below are at 100%.

Demosaic artifacts

Something we observed fairly early on were discoloration and jagged demosaic artifacts which can be seen on some diagonal lines in E-300 images. These artifacts weren't visible in RAW images converted using Adobe Camera RAW, they can also be eliminated in Olympus Studio by using the High Function mode with a 'False Color Suppression' setting of between 6 and 9. Crops below are at 200%.
