I have used Breeze Browser to proceed my G2 RAW files for 2 years and just bought C1 to process these and found that the C1 is much better in the following regards :
i) Higher resolution;
ii) Much better auto white balance, especially for in-door photos taken in Chinese restaurants which use heavily yellow cast lightings;
iii) Flexible controls available for tint, white balance, exposure, and color saturation;
iv) Controls available for cropping
v) More vivid color (not just heavier color saturation) achieved.
I think the recent upgrade of C1 to process G2 RAW files is a big news for G-series users, and I recommend all those using G-series to try the C1, a trial version is available on C1's web site.
