Canon Ixus80IS... one of the most common point and shoot cameras around. 
and no, i did not photoshop ( i dont know how to), but i adjusted exposures for about 2/3 of the shots using iphoto 08. mostly increasing by about 0.3 to 0.5....
One thing about this camera is that every shot you take is a little underexposed... If you weren't fussy, you wont notice it, but i find that increasing the exposure on the computer brings out the colours more.
Could be because of some 'fog' in my camera's lens or something. My camera hasn't really felt the same after i came back from kiruna (-40 degrees centigrade). And on one occasion, it fell face down, lens open into waist deep snow when i was attempting to take photos on a dog sled. the shutter was stuck for half a day. haha.
the bright and amazing colours are mostly attributed to the camera's vivid mode function.
