First of all, I think the icon you're currently sporting (it looks like a temple) is beeeeautiful! All the details and colours really pop out at you! I assume it's a picture you took on your trip.

Same! I'm always doing weird stuff like adjusting hue/saturation, playing with layers, then I'll save it as a .png or whatever and then do more to it at that stage.

Yeah, I'm notorious for adjusting hue/saturation and colour levels. My favourite adjustment layer to play with is probably brightness/contrast. I find it particularly useful if I've got a screencap I like, but it's really dark and it's hard to make out details. Usually, I try to save things as .psp files until I'm pretty sure I'm finished with them. Still, it's hard to leave icons alone even then. Like you, I've gone back to fix things, though I usually just locate the .psp file and work from that.

Good luck with the note taking :)

Thank you muchly! :-) It will be interesting to see if I actually remember to do it. I'll let you if the note taking is successful.
