I shoot in RAW and other than correcting the light balance, cropping (only crop where needed) and resizing I don't do much processing, I don't have photoshop and don't really know how to use it
The photo of the 2 zebra's and the penguins are as they were taken except for sizing of course. Pity about the visible smudge marks on the glass in the tiger enclosure, felt like taking a cloth to the class and getting all the handprints from the kiddies off.
