One of my better images at the Terlingua Ghost Town Cemetery
The image was made with a Nikon D750 & Nikkor 20mm f/3.5 lens; ISO 9000 at 30s at f/3.5. There is considerable noise at this ISO, however, using a software called Neat Image, it eliminates it.
The image was process thru ACDSee Pro 9 and saved as a TIFF file. It was opened in Neat Image and the noise was removed and saved as a JPG. I used ACDSee Pro 9 as the final edit step.
