I get Rangefinder magazine, and in with this month's issue was a Canon ad, more like a book really, with lots of 1D and 5D info.
IN there was a link to //photoworkshop.com/canon/ .
There i was reading about how to get teh bst images from your canon (1D moslty) camera and tripped across this bit of info, tried it and YES virgina, there is a santy claws.
to quote"
Apply post-process sharpening effectively:
Canon EOS digital cameras have an anti-aliasing filter installed on the image sensor.
This filter improves color rendition and practically eliminates moiré. The liability is a
slight reduction of sharpness. To reduce the softening effect of the anti-aliasing filter we
recommend applying an unsharp mask to the image in Adobe® Photoshop®. Although
there is no such thing as a “best” setting for all applications, we suggest the following
as a starting point:
Amount: 300%
Radius: 0.3 pixels
Threshold: 0 pixels "

THe info is in a PDF from canon - there is a short version (2 or 3 pages) and a LONG one (35+ pages)
THe long one... //photoworkshop.com/canon/EOS_Digital.pdf Go to page 29 or 30 for lots more info...off to read more now!
BTW, the above does work - try it on the image when you first open it. Even resized to DPC size the sharpness stays! I figured there was a setting that worked, cause back with my Fuji S602 a 500%, .1, 0 did wonders used this way.

Very good paper that appeared a while back. Of particular interest for people here is page 26 where it explains how Canon photos come out of camera from the 1-series to the P & S...1-series = minimal in-camera processing, P & S = lots of in-camera processing...

Went off to the tutorials on using DPP. Man, I am gonna get good if i can remeber this stuff!
My PS efforts: (at b&w conversion)
i have at least 4 actions for convertin to b&w, none of which please me. To convert in PS is not hard, but to alter an image is a long and laborious process.
In DPP, even a JPG capture like this, can be pushed and prodded real time to acheive ANY b&w look you want. Wowee, the world of b&w has opened up for big time!

I've used Canon's method on images and it works better than anything else I've tried, with the least amount of noise, with a couple of caveats:
Do it before any resizing.
Don't use Camera Raw's sharpening first.
I never resharpen my images after resizing with the exception of the images I took with the Canon 75-300 at 300mm. And even that didn't help. :)

dahkota posted two very important aspects to this. In addition, I'd liek to suggest that, although Canon recommends a zero threshold setting, I've found that this will make noise a bit more visible, Setting the threshold to about 2 or 3 works well for relatively smooth images, maybe a little higher if the image is quite noisy.

DPP is Digital Photo Professional. It's the RAW conversion program that comes with Canon DSLRs. If you decide to use it, get the updates from the Canon site.
USM can mean two different things. Canon uses it to signify that a lens has an Ultra-Sonic Motor. But the more common usage is Unsharp Mask, a tool that is found in most photo-editing programs for sharpenning digital images.

DPP is free - go to the canon usa website and look up the software for the 5D or 1D anything. It is called DPP Updater. Just down load that (it may update otehr canon software like the EXIF viewer, etc).
I use it as my first stepo in processing pics (raw obviously and jpg sometimes). now that i have gone thruy some of the tutorials (quicktime movies) i will be using it a LOT more!
