Was looking at the Bali pictures... thought they look fine to me. very natural. Perhaps it has got to do with your monitor calibration. I was having trouble with my camera colours before the calibration. Now much better...
If you want colours that 'jump out' at you, then you'll have to set the colour saturation and sharpness on the camera.
Hi,
Yes, the monitor is calibrated. I even use it to calibrate my office notebook. That way, I don't have any more excuses for lousy shots.
The picture styles were constantly changed because I was still working out my favourite configurations. So keen eyes will notice some inconsistencies. But most of the landscape shots were made with, erm, Landscape mode with some tweaking.
I also noticed that using Canon's own lens produce more 'accurate' (through my own judgement which can be subjective) colours work better with the external flash.
So more ways than not, the colour rendition of different camera/lens combinations will not fully satisfy any individual's likings without some tweaking.
And once you've chosen a system, you might as well spend some time finding out your favourite 'modes'.
