G'day Jose. I looked at the 100% crops first and wondered about the
difference in sharpness and whether the standard in-camera
sharpening made a difference, which of course it can, but we can't
tell just from looking at your sample images. Then I looked back up
at your source images and. Although you tried to focus on the red
apple both times, If you look at the detail on the back inside of
the bowl and the cloth just behind the bowl, it's pretty clear that
the 30D focus was somewhat further back than for the 1DIIN. That
would tend to make the 100% crop from your 30D look so much softer
than the one from your 1DIIN.
As for DR, the 30D certainly exposed slightly brighter, so for
about the same amount of shadow detail, I guess it does seem to
indicate that the 1DIIN can capture a bit more DR, at least when
posting as sRGB JPEGs.
I've just started processing my RAW files using ProPhoto RGB if I
might want to print. When I turn on the highlight and shadow
indicators in ACR (CS2), the difference between the DR (brightness
and colour) of sRGB and aRGB/ProPhotoRGB is quite obvious. ProPhoto
RGB isn't that much wider than aRGB, but it is a bit wider
nonetheless. I wonder whether shooting RAW and processing into a
much wider colour space like ProPhotoRGB would be more revealing of
the differences between the 1DIIN sensor and the 30D sensor.
Depending on the scene, I often want to sacrifice some shadow
detail for increased contrast anyway. If I was using JPEGs straight
out of the camera, then the 30D may even show slightly more
contrast than the 1DIIN for the same settings, which might be
desirable unless the DR of the scene is too high.
Thanks for the comparison. I think it shows that you can come close
to safely using the same picture style settings on both cameras and
getting a close enough result.
