PhotoSorter/photoSort2.py

##Made by Donavon McDowell
##A script used to sort through a large set of images and get rid of any bad ones aswell as put the new ones in a folder that contains only good images

## Read through the root file
## Open each file representing each month
## Open both Spillway and Toe Berm folder
## Read each individual image
## Get rid of any that are taken after dark 
##Bad times 0600 and 1800 are dark

##The folder that contains your unsorted images

##The desitination folder

##Destination Folder Name
destination_folder_name = "Spillway Verified Images"
##Reject Folder Name
reject_destination_folder_name = "Spillway Rejected Images"
