Software and RAW conversion

RAW mode

The G10 retains the RAW mode that made its comeback in the G9. The resulting RAW file is bigger due to the larger sensor. One difference in the G10 is that if the camera is set to RAW+JPEG mode, the camera records a fine JPEG, where the G9 recorded an extra fine JPEG in addition to the raw image. Shot-to-shot performance is still very good in the G10. The 'my colour' modes of the camera are turned off when RAW mode is used (either RAW or RAW+JPEG). Overall the RAW mode in the G10 is very usable, allowing the user to have full control of image parameters such as white balance, exposure (to a degree), and colour treatment, after the shot has been taken.

Supplied software

As usual Canon supplies a comprehensive suite of applications with the G10, including an updated version of its ZoomBrowser for Windows and Image Browser for Mac. Canon now also ships the full version of Digital Photo Professional (DPP) with the G10 (version 3.5.0.0). This is the same software that comes with EOS digital cameras, and includes all the controls you need to process a RAW file - from exposure, saturation and sharpness settings to noise reduction and curves and levels adjustments. There is a lens correction option in DPP, but in this version it cannot correct for the lens in the G10 (though it can do for many Canon SLR lenses).

DPP also includes picture presets, and a comprehensive set of controls (including a new Adaptive Noise Reduction filter and a full set of 'MyColors' presets). While the range of options may not be as sophisticated as other RAW converters, such as Adobe's Camera RAW converter, the fact it is included in the purchase price means that users will not need to spend any more money if they want to fully utilize the RAW mode.

JPEG & RAW Resolution compared

The resolution of the G10 JPEG is very good, but there is still a little bit more resolution available in RAW (though it is a little more evident in ACR than DPP).

As the crops below show the camera is by default applying quite a lot of sharpening during JPEG processing. Raw files processed with DPP (using default settings) show less sharpening than the JPEGs as does those processed using ACR (using the default settings) - perfect for post-processing - and have a little more usable resolution. Note here we're using ACR 5.2.

ISO 80 Studio shot comparison (JPEG vs RAW)

Canon's Digital Photo Professional (DPP) produces results that are similar to in-camera Jpeg in terms of colour, but looks crisper with more detail. Adobes Camera Raw produces a look that is a little softer and not quite the same colour tone as Canon. This may not be such a bad thing as it leaves the processing decisions to the user. It is possible to obtain the Canon 'look' in ACR, but then it is also possible to obtain the ACR look in DPP.

ISO 400 Studio shot comparison

The ISO 400 shot illustrates better the different approach taken by DPP and ACR. Again DPP produces similar detail and noise as the in camera JPEG. The noise levels are kept quite low, but there is a slight loss of detail. ACR manages to retain slightly more detail in the image, but at the expense of more noise. Both DPP and ACR can have the noise reduction turned down so the user can apply separate noise reduction (such as Noise Ninja, or Noiseware).
