Shot with G3 in LS mode - no editing, only cropped, reduced by 10% to 1000px width and saved again as JPG. But it shows clearly what the original file looks like.

The issue is the outshining of the twigs by the background, as can well be seen along the twigs running across window, wall and sky. It depends on the apparent width of the twigs and not only kills the colour, but reduces the sharpness excessively. My question is whether this is only due to LS/JPG mode and could be avoided in CRW?

How about the present state of the RAW conversion? Is CRW that much better than LS in this respect? Is it worth the hard work in handling and editing (as per previous posts)? Or am I just asking too much?

TIA

Looking at that picture for a while (until I saw pink spots in front of me :) ). I think it is a simple focus problem... Did you use a tripod/what was the shutter speed/was it windy and the branches moved?

I am convinced that going to RAW would not have improved this image. Just my opinion and I might be totally wrong ;)

Oh and I just learned that F8 is causing diffraction problems, and I should rather use F4 or 5.6... so perhaps...

What exactly do you mean by "diffraction problems"?

Sorry for omitting EXIF data in the first place:

1/1000sec. at 4.0, focal length 12mm, subject distance 66m - plausible. If there was any trace of wind, it wouldn't have mattered at this speed. The wall colour is pretty well as remembered, so CWA metering did a fair job.

The only manipulation apart from the mentioned cropping/resaving is rotating by 90 deg. in Breezebrowser.

So I see no explanation here. Is this a "feature" other attentive G3 users observe as well - or has it probably something to do with my own camera? I feel this a significant matter.

Thanks for replying.
