+    Function that extracts tiff files from specific cameras and returns a list of all
+    the tiff files corresponding to that camera. i.e. all pictures labeled "_7.tiff" or otherwise
+    specified camera numbers.
+    
+    Parameters:
+        images (list): list of all tiff files, regardless of classification. This is NOT a list of directories but
+        of specific tiff files that can be opened right away. This is the list that we iterate through and 
+        divide.
+        
+        num (str): a string designation for the camera number that we want to extract i.e. "14" for double digits
+        of "_1" for single digits.
+        
+    Returns:
+        tiff (list): A list of tiff files that have the specified designation from num. They are the files extracted
+        from the 'images' list that correspond to the given num.
