HX1-more on Antiblur and Twilight

I thought I would share some more specimens comparing the two modes, antiblur and twilight, on the HX1. First, note that noise reduction is an issue. Here is the set-point of my particular cam, using overcast, gray sky, at 200% crop for emphasis:

LowNR LEFT, MedNR MIDDLE, HighNR RIGHT

Now, compare the above with noise reduction in the modes in question. Note that in antiblur and twilight modes, the user looses control of the noise setting. The noise menu item disappears when these modes are chosen:

LowNR LEFT, Daylight Antiblur MIDDLE, Daylight Twilight RIGHT

What needs to be noted is that, even though both modes work hard to eliminate noise, they do so quite differently. The antiblur mode always has two characteristics in daylight shots, which also are fairly regular in low-light shots as well: (1) more aggressive smoothing, which equals much less detail, and (2) lighter exposure, which reduces dynamic range. While the twilight mode has more chroma noise, we will see that this mode also has better dynamic range and more detail than antiblur in daylight exposures.
