Harvey, my outdoor rabbit posing for some portraits. Images taken with a Nikon D300 camera and 80-400 mm VR lens. It was getting late and the amount of light was going down, so I was pushing the ISO higher. Images reprocessed with the new standalone Topaz Denoise AI program to remove the background noise. In the past I mainly used the NIK Define filter to reduce the noise level in high ISO images. For troublesome noisey images (especially jpg images) I would use a previous version of the Topaz Denoise filter.
