So, took a walk with friends and their dog - was super chuffed with the below on the camera screen, then got home and found I'd left it in ISO6400 from my previous shoot - DAMN! The buildings were all noisy etc... So used my newly bought Aperture to try and fix it - no luck - any tips on noise reduction welcome - literally any radius/edge settings made NO DIFFERENCE - i'm convinced it wasn't doing anything! I also forgot to switch to RAW, not sure if noise reduction is just crap on JPG? Anyway, switched to B&W and bumped the contrast and ended up really liking it this way anyway!
