I have about 1000 images from my son's (and nephew's) graduation. It was later in the day, and I was steadily loosing light,so I kept bumping up my ISO. Now I want to batch process them, including noise reduction, but the NR will be different based on the ISO used. How do/can I quickly sort the files by ISO so I can do each ISO batch? Looking at the exif of each image will take longer then the relatives would want to have to wait.
I have LR5, PS6, DPP, and DXO9, but want to do the processing in LR5.
