Alternative method of sharpening images

Here's a way to not only sharpen images without creating over-sharp halos and other artefacts that can creep into an image due to excessive use of Photoshop's sharpening filters, it also gives your image improved detail, definition and contrast at the same time.
The reason it is so effective is it only sharpens areas of your image that have edges to them. Areas that are not an edge are left untouched. For example, clouds in a scene remain looking 'real' (soft) whilst edges (trees, masts, buildings, etc) are sharpened. You get a more realistic result without the sharpening being too obvious.

This is an experimental video I've made - sound levels need more work, resolution may be a bit small and it needs Intro and Exit footage added - but it's an opportunity to see what happens when we post videos into our blog. Resolution is 1280x720 so I hope it's not too fuzzy when viewed at full screen on your machine.
It's just on 6 mins duration, in .mp4 (mpeg4) format. I hope it plays OK on your machine without crashing it.

The original mpeg file of this when viewed normally in Quick Time is not pixelised like this Blogger must do something to the file during uploading.
If you can follow the sound track you'll still understand the steps to go through.
Oh well, uploading videos to the blog may not be a great idea.

Sound track is great, resolution too low to appreciate the result on screen, guess I'll have to do my own. Thanks Roger, a good effort.

A possibility - you could upload videos to youtube then embed them into the page.

Yes Benjamin, after looking around YouTube specs, etc, I'm convinced that's the best answer. I'll probably do some more experimenting/testing when I get back from holiday
