Sharpening for the Canon G9 (RAW)
« on: October 16, 2007, 08:54:29 am »

Let me begin by noting that there is another thread on sharpening that discusses techniques and software.  In this message, I hope to get comments on differences (if any) between techniques and software that might be used for high resolution digicams and DSLRs.  OK, I really want advice about my Canon G9 RAW files.

I have a Canon G3 and a 20D but couldn't resist the new G9.  I've had it less than a week and like it a lot.  It is a bit noisy, etc., etc.

I shoot almost entirely in RAW.  I've used the three step PK Sharpener methods for several years and have liked that philosophy and results.

Since the G9 has a small sensor and 12 megapixels and can quickly get noisy, I wonder if a variation of my old methods -- especially using PKS -- is more appropriate.  If so, what variation?  I've been tinkering with Smart Sharpen and combinations of Smart Sharpen with PKS.  At this point, I'm still learning the use and effects of Smart Sharpen but it seems to have a place in my workflow.

digicams tend to have more aggressive AA filters, so you'll need to do more aggressive capture sharpening to compensate. You'll also have to do more noise processing than you're used to. But other than that you shouldn't have to do too much different.

I had been in the habit, I suppose, of using PK Sharpener Capture Sharpening at the "Wide" setting.  With the G9, that wide setting seems to brighten up the image too much  (perhaps generates too many highlights is the better term).  After tinkering around a bit today, I've settled on using the "Superfine" capture setting -- certainly for landscapes, perhaps something different for people.

Smart Sharpen is really intriguing and I'm trying to get a better feel for it.  The G9 images seem to benefit from a bit of Smart Sharpen.  Actually, the default setting seems pretty good although I've tinkered with fading the highlights.

... there are only an infinite variety of combinations!
