To compare real-life RAW performance on the Panasonic Lumix DMC-G3, I shot this scene using RAW plus Fine JPEG mode at the camera's base sensitivity of 160 ISO. The G3 was set to its 4:3 aspect ratio to record the highest resolution image.

The Lumix G3 was fitted with its standard 14-42mm kit lens, set to f5.6, and the focus confirmed with magnified assistance.

The image opposite was taken with the Panasonic Lumix DMC-G3 at 160 ISO with an exposure of 1/640 and the lens set to 20mm f5.6; the original Large Fine JPEG measured 8.29MB. The crops below are taken from the areas marked with the red squares and presented here at 100%.

I processed the RAW file using the supplied SILKYPIX Developer Studio 3.1.6.0 SE software using the default settings. At the development page, I set the Unsharp Mask amount to 100.

On the previous pages we saw how the Lumix G3's in-camera JPEGs using the default settings could come across as a little laid back compared to some consumer-targeted cameras. By shooting in RAW and applying the default SILKYPIX settings though, you can enjoy a much punchier result.

The default RAW processing has applied greater contrast and sharpening without suffering from any obvious artefacts. Look really closely and you may notice more obvious posterisation, particularly in the second row of crops, with the houses exhibiting a slightly painted-look, but overall I'd say the RAW version is preferred to the JPEG. Like all RAW processing, you can of course make the exact adjustments you want for the desired result.

Next let's check out the High ISO performance with the Panasonic G3 vs Canon T3i / 600D noise.
