These black and white photos were taken in Chicago in early 70's using a Nikon Nikkormat FTn with black and white films..
Nikkormat Ftn was built like a tank and all metal in construction. It was heavy but I had many interesting photos taken with this camera.
I no longer own this camera but I have two Nikkormat FT2.
Here are some sample photos.
Lake was frozen.
I sold a print from Etsy one time.
