Thanks everyone for your help and advice and assistance,It really helps
I am using CS 5,but I am going to go back to using the
Canon DDP software that came with camera,first,
and then use CS 5 for borders and similar.
I have been selling images to my U.K publishing agent,and he has never said anything about 'noise' on my images.
But occasionally I have the odd few people here tell me my images are not good due to noise,-that is why I rarely
post here.I was also told by someone on this forum that a
Canon 50D is no good,because of the high noise,I thought
I might have to sell it and buy a 7D,But its only the same couple of people that find these 'faults' so may be I should'nt
worry too much.
I sometimes have to use
iso 400,for birds and aircraft in flight,so I can up the speed as much as possible,so might try using
lower
iso and lower speeds.I'll follow up the suggestions here-they have been helpful.
Thanks FB
