High pass sharpening tutorial

I think it goes without saying that the majority of panos, especially those shot with FE lenses, deserve a portion of sharpening treatment.
There's a comprehensive tutorial which you can find by searching the forum (sorry, Im too lazy!), which also covers the high pass sharpening technique, which in my opinion is the best of the lot.
Below is a short and sweet tutorial, its really worth a look.
The HPS method is easy to use, very flexible, and you can even record a quick little action to simplify a step or 2.

Gosh Gus, didn't want to upset you 
You're in the UK so its one hour earlier then here. While I'm writing this, it says posted 8 hours ago above your reaction, so it was about 5 PM you posted this. Did you miss your tea or did you just exaggerate a wee bit
But seriously. I'm glad you did your search because it's a really good article, that guy really knowns to explane it well.
(goes for the other articles as well.)
Thanks, you didn't waste your time

I have a cruisy job with a lunch break every 3 hours
It's certainly a good article, bit long though. Only thing that was not sharp after reading that article was my vision - which went blurry!
So have you tried the HPS technique?

Yes, i tried it.
And i'm happy with the result.
But I find it works best on detailed pictures
When i applied it on a picture with a lange white wall with some black iron in front of it, I got halo's even by looking at the radius slide.

Nooooo - please don't start another acronym fetish. It's gotten to the point where new posters seem to think that they can't shoot a pano without (HDR), properly called tonemapping (it isn't HDR no matter what anyone else says) and now it looks like we are going to get a HPS obsession to go with that.
Yes, panos do need some sharpening (to some degree) and there are a number of ways to achieve this. Using the High Pass filter is a good option, I prefer it myself BUT it isn't the only way and it isn't always appropriate.
For those who haven't gone to the linked feature - using the High Pass filter is very easy - make a duplicate layer, apply the High Pass filter, blend in hard light, set layer transparency to between 60 and 80%, flatten - there you are.
The only bit requiring any thought is setting the pixel radius and that requires some experimentation. Setting the transparency also requires the user to exercise their own judgement. I can't see the point of using an action as each case has to be judged and it is so easy to do anyway.
If you are new to pano photography you would be better advised to learn how to obtain correctly exposed images, shot at the optimum Fstop setting for maximum sharpness before starting to fiddle with PS - especially if you don't fully understand what you are doing. When you are ready to go that bit further there is so much material available to guide you - not only online, you could even read a book!
Tonemapping obsession often leads to ghastly over processed looking images, please lets not have wierd sharpening artifacts as well.
These are not the droids you are looking for
