The Three Sisters (2694, 2769, and 2936 m) are a well-known and much photographed Rocky Mountains landmark above the town of Canmore. On the left can be seen Rimwall Summit (2680 m). I was fortunate to have a crisp atmosphere early in the morning while climbing Grotto Mountain on the opposite side of the Bow Valley and decided it was worth to take some shots. The Bow valley channels the warm, dry Chinook winds that blow away and evaporate the snow and consequently many of the peaks adjacent to the valley can be climbed year around. Sharpened using Luko's well known protocol.

Let me try a translation of "Luko`s well known protocol".
1. "-USM: effect 18, radius 40, threshold 0"
This is the so-called "hiralom" sharpening or High-Radius-Low-Amount sharpening, badly applied because the threshold usually is more than 0. If you use 0 for the threshold you will apply this hiralom which is basically local contrast increase to everything, noise included. The "Father" of this way of sharpening is Dan Margulis and Google is your friend:)
2. "-USM: effect 150, radius 0.3, threshold 0". This is the conventional use of the Unsharp Mask filter. The 150 for the "Amount" (not "effect"!) looks OK but "Radius" is dependent of the resolution of the photo. Your camera (Canon 20D) being a relatively high resolution camera and working on the full size photo the setting should be between 0.5 and 1.5, usually 1.
3. Again, because you don`t want to sharpen the noise, the threshold should be more than 0, something along 3 to 5 for 100 ISO photos and more for noisy photos.
4. Very important and the biggest mistake here, in this workflow: You never apply the conventional USM AFTER hiralom, because you don`t want to USM sharpen something which has already been sharpened. So, it should be step 2 first and then step 1.
5. "-go to edit, then fade USM: opacity 100%, mode darken" When you sharpen you basically increase the contrast of the edges, so the dark edges get darker and the light ones brighter. It has been noticed that light halos are more noticeable than dark ones so it`s a good idea to do the sharpening on two separate layers, both copies of the hiralom sharpened layer. By setting the opacity of the light halos layer to 50% you make it twice as less pronounced as the dark halos layer.
I`ve learned many things from Dan Margulis but the most important of them all is to "why" first and the "how" afterwords. Learning the fundamentals will make you smile when you see such a "not-so-secret-recipe" on the Net.:)
If you`d asked me, the only problem with your photo is not the sharpening but the very contrasty light which turned the forest almost black. You should have been in that location at sunrise:)...

That's a wonderful landscape picture!
I love the shapes of those mountains... they're mighty magnificent!
Your picture has excellent sharpness, exposure, colors, chosen pov, dof and composition!
TFS - congratulations!

A beautiful valley crowned by those monumental snow-capped mountains with a funny name.
Great perspective and wonderful light and details.
