Panasonic Lumix DMC-GH1 Review
The DMC-GH1 is supplied with a Software CD containing:
- PHOTOfunStudio Viewer 3.1 HD Edition (Windows) - A photo browser / editor with some basic workflow functionality (also includes a tray icon automatic import tool). While PHOTOfunStudio Viewer was able to view GH1 RAW files it couldn't convert them to JPEG and wasn't able to display all exposure information (clearly didn't fully support the GH1). This latest version of the software also offers some HD video editing.
- SilkyPix Developer Studio 3.0 SE (Windows / Mac OS X) - SilkyPix is a RAW conversion application developed by Ichikawa Soft Laboratory which is probably better known in Japan. SilkyPix provides a wide range of advanced RAW conversion options including adjustable noise reduction, lens aberration correction and rotation / perspective correction.
As with other Lumix models the GH1 ships with a special (fully featured) edition of SILKYPIX, a rather quirky, though surprisingly well-featured, raw development application for Windows and Mac. The (on-screen) manual is very comprehensive, but doesn't really explain the features very well, and first-time users may find themselves overwhelmed by the sheer volume of options on offer. This isn't helped by the slightly dodgy translations and the plethora of sliders with names that don't really indicate what they actually do. But there is lots here to get stuck into, and the default settings produce perfectly acceptable results.
But after some experimentation and adapting you'll discover that the SILKYPIX can produce far superior results - and can be fine-tuned to produce output that suits your own needs / tastes. In fact there's easily as much tweaking on offer than you get with Adobe Camera Raw, and compared to what you get with most cameras it's hard to complain.
You can save parameter sets (for some reason you put them in the 'cloakroom', but hey ho) once you've found out what works for you, which combined with batch processing and extensive output options (TIFF or JPEG), takes some of the grind out of the business of developing large numbers of raw files.
As is normal in our digital SLR reviews we like to compare the supplied RAW conversion software, any optional manufacturer RAW conversion software and some third party RAW converter. In the case of the Panasonic GH1 we used the supplied SilkyPix Developer Studi0 3.0 as well as Adobe Camera RAW 5.4.
- JPEG - Large/Fine, Default settings
- SPDS - SilkyPix Developer Studio 3.0
- ACR - Adobe Camera RAW 5.4
Place your mouse over the label below the image to see the color from a GretagMacbeth ColorChecker chart produced using each RAW converter. Typically we are used to seeing almost no difference between in-camera JPEG and the supplied RAW converter as it is normally intended to exactly duplicate the color response of the camera. However the SilkyPix software was not developed by Panasonic and clearly has a completely different color map, this means that RAW images converted through SilkyPix will immediately have a different 'look' to them than the out-of-camera JPEGs. Interestingly ACR's output is much closer.

Sharpness and Detail
The sharpest and most detailed image was from Adobe Camera RAW 5.4, closely followed by SilkyPix. However, the GH1's JPEG engine is doing a pretty decent too and produces very detailed images straight out of the camera.
|SILKYPIX RAW ->JPEG (Default settings, manual WB)
ISO 100 studio scene 100% crops
|Adobe ACR 5.4 RAW ->JPEG (Default settings, manual WB)
ISO 100 studio scene 100% crops
|JPEG out of camera, High quality setting (all settings default)
ISO 100 studio scene 100% crop
These crops demonstrate that there is some more detail available from SilkyPix and Adobe Camera RAW conversions of RAW files than can be obtained from JPEG. That said, a lot of this detail could be described as 'false' (produced beyond Nyquist), although frankly the majority of the time this is useful as it improves the appearance of 'texture'. ACR squeezes even a tiny bit more out of the RAW file than SilkyPix but shows, like SilkyPix, some unpleasant artifacts. The out-of-camera JPEG is the cleanest image in this comparison.

Real word advantages
After playing around with the GH1's raw files a little it's obvious that when shooting at low sensitivities there's some extra detail you can eke out of the RAW files but it's not an awful lot. The GH1's JPEG engine is already doing a pretty decent job the real advantage of shooting EAW with a camera like this comes down to being able to adjust parameters such as white balance, contrast, sharpening and so on, and to tailor the output to your own needs.
