IR plus UV filter - plus some fiddling with the RGB levels - can't remember exactly what - and it's a bit odd that the bright blue overexposure is still unchanged. All in all - a terrible experiment because I like the leaves but can't remember what I did to get them!
@koalagardens Thanks Katrina - that's something I had never thought of doing.I have a folder of backgrounds and cutouts but not of home made textures. This can be the first one but I might not edit it yet - just leave it as it is and edit it each time to suit whatever it's being used for. Thanks so much for the suggestion. Cheers Rob
