I think I prefer Martins suggested crop and colour boost, the sun is far too dominant in the original and distracts from the scene.

Brilliant idea Stefan, but you missed CF which is a bit strange because you remembered to include SD

And yes, CF is related to Pentax as it was used in the istD.

I use PS7 (yes I know its ancient) but I would think they are similar.

From the menu at the top choose "image" then "image size" this should open the box for making adjustments, the figures in there should be the current size. as you can see you can change by either pixels or cm. I always do it by pixels. NOTE there will be a check box in there with something like "constrain proportions" this must be unchecked otherwise the hight will automatically adjust as you change the width.

Admit it Ken, you got a neighbour to stick a pole up his rear and shove him up the chimmney

Cropping is pretty much a matter of personal choice with images like this, its not as if you have to decide where to put the donkey in a landcape is it?
If the image was mine I would simply go for a total abstract by removing all of the black background and retaining as much of the coloured pattern as possible, even stretching the image width afterwards to return to a more attractive aspect ratio.

Lovely shot though, and the colours are gorgeous.

At the end of the day it all come down to lack of funding and as a consequence a severe lack in the standard of training, I for one am appalled there are so many officers on the beat who basically dont know what their doing, but dont blame the individuals. blame the idiots who send them out on the beat ill equiped and ill informed.

Nice shots guys, I bet your over the moon with them

Who needs the Police to disperse G20 Protesters? just drop a few thousand of these onto the crowds from a helicopter and watch them run

Tremendous shots Don, superb detail.

High ISO shots have their place and often work, this unfortunately isn't one of them, I agree with Richard, for subjects like this keep the ISO as low as possible. It is still rather good though despite the noise

How about ISO6400? (scroll down to last shot)

Excelent point
