As an aside, today I worked on an image in DxO where 75% ClearView made sense. It doesn't happen too often but this time it did. And it doen't look anything like an over-the-top HDR look, in my opinion:
Just from my own POV, this image does step over what I'd choose, obviously YMMV ;-)
I've not found an image yet where I was happy with the default ClearView setting - useful, but in small amounts.
I've found when using DxO, the lens softness setting is the one that pushed edge contrast too high for my liking, especially noticeable when enlarging a lot. Indeed I'll regularly turn off (or much reduce) this setting whilst keeping the other lens corrections (depends on the lens and subject).
I've a short note on creating a 3m x 2m print from an 11MP Canon 1Ds image, where I look specifically at this aspect at one stage (about 1/3rd into the article)
http://www.northlight-images.co.uk/tutorial_pages/innova-big.htmlIn previous reviews of Optics Pro I only looked at shots taken with good 'L' lenses, so this one steps away a bit in using the EF-S 10-18 on a 100D. I've not seen Optics Pro make such a pronounced difference as it does in the wide shot of a field, with the viaduct in the distance. It's actually enough that I'm much happier having the 100D (with 10-18 and 15-85) with me as a small backup camera on my commercial jobs.
