These are some photoshop tricks to make your shot look better
I often apply these to my pics I post in the freeware section. Not for the competition 'cause I don't know if this is considered editing or not. Personally I think this is only a little enhancing, but I'd like to hear other peoples opinions about this.
First : the pic before enhancing. A quick setup of a Super Etendard above Brussels National.

Second : apply an
unsharp mask (in the sharpen section of the photoshop filters). Just fiddle a bit with the sliders untill you think the result is right. This makes the lighter parts of the pic brighter and therefore the pic looks sharper.

Third : add just
a little contrast to the pic (not too much!). This will make the colors more vivid.

Its very important not to overdo these effects. Just make it look as realistic as possible. (actually, I think I already overdid the "contrast" effect

)
