:laugh: I think your loosing it Steve!
funny though, I was the bass player too in that band.
I'm the singer now in this band which is cool coz I don't have
to carry any fecken gear around any more!!
Back to topic!!
(before the mod police give us a virtual clip round the ear)
Mike.
I've done a few tests this morning with a lunar image I have.
(trying to figure out is there a numerical or systematic way of
sharpening by a pre determined certain amount for a particurlar fraction of the origional image.
Without wasting more of my life in front of a PC,
the answer I keep getting is a resounding NO.
This is not something that you can apply a formula or rule of thumb to.
Your just going to have to adjust or process each shot on an
image by image basis using your peepers.
This is where having 'an artistic eye' might come in handy.
So as Mike says,
If you want to display an image on the web /pc as a smaller
size from the original then you should resize first.
Then do the sharpening.
Just don't use this smaller version for physical prints or
mail them out for publication to magazines etc.

I tend to sharpen at the end too. After processing I tend to ctrl-NJE (blend all layers below) then save 2 different images. Resize and sharpen the top layer for ea image.
I also find that for large image areas Gaussian wavelets are better in Registax than the standard.
I played with a drummer once whose snare was so tight it would cut you in 2 if you stepped within 10yards of it!
maybe we could start an astro band.....The Symbolics..but I want to Sym!!
