From the mail bag: Good ISOless pictures today. The only question that comes to mind is whether LR’s default noise reduction parameters are fine tuned for the given ISO. I thought I read somewhere that they do that sometimes. Good point. Here are the images with sharpening and noise reduction turned off. But then there’s… [Read More]
