Ok, next up, a quick test of the HDR mode.

I took a 3 shot bracket hand held on a windy day here. This is the middle shot for illustration, processed using DPP defaults whatever they are. Two more shots were used, 2 stops above and below this. The sun (through the clouds) is in shot to the top-left of the image.
As I hand held this, I used the auto-align function. This seems to crop the image somewhat as the following images show less field of view than this unprocessed one. I took it through the various built in presets before trying my own settings. Unfortunately this image looks a lot worse reduced to this web size, but I don't think it worth showing bigger either...

Natural preset. It does feel natural but really dull and low contrast. Might be an ok starting point for further processing.

Standard preset. This perks up a bit. Everything in the dynamic range looks clearer.

Bold preset. This is more like HDR - saturated colours and generally more in your face.

Embossed preset. I don't get this one. Seems to be quite a bold setting with strong but not complete colour desaturation.

My custom setting after playing about a bit.
I don't know what all the options mean yet. There are two boxes. The first one labelled Tone/Color is more simple. Here you adjust Brightness, Saturation and Contrast. The second box is where the HDR goes on I guess, but I don't know what they do exactly. Labelled Detail Enhancement, you get to alter Strength, Smoothness and Fineness. The preview process isn't the fastest if you're used to getting instant feedback.
There is a bit of halo-ing going on around the rock cluster to the left. I don't know if there's a way to control this better yet.
