On a chance I purchased the Topaz Denoise plugin for Lightroom. I have to say I am very happy with what it has done so far for me. I was out shooting this weekend in low light at the Bolsa Chica Reserve. It meant I was going to have some high iso shots so I am really looking forward to going through and fixing some of these shots and making them look even better. Here’s an example of an ISO 10000 shot that I did, the original isn’t bad, but it is noisy. I ran it through Topaz and chose the clear option and it looks so much better.
