anti alias problems

[Dave Buckley]

i have some weird effect on some edges of my render, the thing i don't understand is that i have been rendering the scene throughout the last two days and haven't had the problem, it is only now that i have increased all the sample settings and subdivision settings

 

at the minute i have

 

dmc sampler - 1 & 64

reinhard with sub-pixel mapping and clamp output checked

irradiance map on high

light cache on 2000

min samples 64 etc

all lights with 2000 subdivisions

all shadow subdivisions at a minimum of 32

 

i don't understand why its happening just as i want to render the final still out

 

it can be seen on some of the edges in the screen shot, (edge of plates, some cupboard handles, worktop near the window, clock hands)

sorry guys, the problem went when i took it into photoshop reduced the size (i'd rendered at double the needed size) and then sharpened it

 

below is the finished render, i will post in finished section also for comments and crits

 

not sure which to submit as final (lighter or darker)

 

anything else i can do to it
