Shooting Straight B&W

Yesterday I changed the Nikon to Black & White for a change. Any B&W’s I post have always been converted on my Mac to that mode. These photos are a test you could say. I tried adjusting the ISO at different settings, a setting of just 100 seemed to give the results I was after but still wanted a bit more texture. These photos are straight out of the Nikon, nothing has been done to them except reducing the file size.
