300D vs. 20D noise and banding - identical conditions
Dec 8, 2004

Here is the result of 2 100% identical comparisons between the Canon "Digital Rebel" 300D and the Canon 20D.

Results were reached as follows:

  • both cameras were set to the same shutter speed and aperture

  • the same lens was used for all test images (17-40mm f/4L)

  • all images were imported into Photoshop using CRAW and all settings were set to zero (0) for importing, no sharpening or otherwise applied

  • level sliders were applied equivalently to all images (input values: 0, 1.00, 42).

The result is this combined image which shows 300D noise vs. 20D noise and banding.

Conclusions:

  • the 300D has noise, the 20D has noise.

  • the 300D has some very light banding present (seems to be spread out more than the 20D)

  • the 20D, however, has excessive banding

  • the 20D also has more apparent noise at high ISO settings.

Here is the proof:

Here are images showing the photoshop levels settings, and also show the 20D has prevalent banding compared to the 20D.

20D:

300D

Note: these tests were performed after installing 20D firmware 1.1.0.
