Compared to the Canon EOS-D60 contd.
Outdoor scene comparison (part two)

- Canon EOS-D60: manual exposure, default params, Manual WB, RAW, Sigma 50 mm F2.8 EX macro lens
Raw converter settings:
- Sigma Photo Pro: default processing, output 8-bit TIFF (sRGB)
- Canon File Viewer Utility: default settings, output 8-bit TIFF (sRGB)
Comparison with an enlarged SD9 image
I thought it may be interesting to see how well the SD9 image enlarges. To do this the SD9 image was output from Photo Pro using the 'double size' option (creating a 4536 x 3024 output image, click here to download - 5,285 KB). This enlarged image was then loaded in Photoshop and reduced in size to match the EOS-D60 image size (3072 x 2048). Crops below were then taken from the original EOS-D60 TIFF (as above) and this newly created SD9 enlargement. Crops were then magnified 200% (nearest neighbour interpolation).
|Sigma SD9, 3072 x 2048||Canon EOS-D60, 3072 x 2048|
|ISO 100, F11, 1/125 sec||ISO 100, F11, 1/160 sec|
At this stage I'm thinking "this is getting interesting". As you can see the SD9 image enlarges quite well, and it shows that it's carrying at least as much resolution / detail as the EOS-D60. I for one did not expect this result but am pleasantly surprised. It's worth noting that the D60's image is cleaner, there are a few line edge artifacts in the SD9 image especially around highlight detail (looks like CA).
