The  slides were  scanned with a Nikon Coolscan 5000ED.  They were  scanned with Win10.  You get a DVD with the scanned images. The resolution of the scan is Resolution Height 2652 pixels  X Width 1792 pixels Horizontal and vertical resolution is 44dpi the bit depth is 24.  My scanner adds a light cleaning function when it makes these scans.  

The infa red clean up function on my scans makes the scans better than the slides.  These slides date to 1970.  They were taken at Sorenson's Resort at Lake Tahoe California.
