I've just seen this - it's a few days old, but some of us would be interested.
It's an in-depth explanation - with visual examples - of the Pentax Custom Images presets (with notes about their customization, as well).
And it's in English - no pesky Google translation needed.
Excellent! I hope they'll add more and more such content (how about... AF modes?)
Give further expression with PENTAX "Custom Image" | RICOH IMAGING
P.S. I'm not sure this is actually News - except for the news of Ricoh Imaging stepping up their English communication. It's definitely not a rumor
If there's a more appropriate section...
