Thanks for the comments.
Eric, this was the standard 14-45 kit lens. It's interesting the comments on other threads about the RAW processing in-camera doing optical correction for this lens. I see this as a good thing that the camera, lens and firmware work in concert as a system. This may be the way of the future.
Ishpop: No offense taken. The fact that they look like they could have been taken by any run of the mill camera is a good thing. The camera shouldn't be the deciding factor in how well an image works, that's between the photographer and the audience. At the very least, I can say that the G1 didn't get in the way of creating these images. Actually, with the ergonomics of the swivelling LCD screen and the EVF working in all kinds of light, it was a big help.
Tuolomne, I shoot low-res JPEGs along with RAW. I use the JPEGs primarily for referencing which shot is what in Windows Explorer and PS6.0, and other software that doesn't read the G1 RAW files or give thumbnails of RAW images. I also output to JPEG for online posting and quick-lab printing on RA-4 paper.
So, since JPEG is my final output, how I get there could be either by letting pre-programmed firmware decide what the JPEGs will look like, inside the camera, or I can do it in SilkyPix. There's also the option in the G1 of custom film settings for JPEG output, like amping up the color and contrast, etc. I prefer to do it in post because I like the results in SP, and my PC monitor is a bit better than the LCD screen for deciding these things. I also like taking my time doing it after the fact, rather than cutting into my shooting time and doing it on the fly, in-camera.
So the answer to your question is that I used a manual workflow to generate these JPEGs with this particular intensity of color and contrast, rather than letting the camera do it for me in an automatic workflow. Think of it as another custom film setting, it's just done in SilkyPix.
