Does Mott tone these photos or are these the actual "raw" image?

Actually physical therapists / sports therapists still use machines similar to these, when I had a sports injurt I would do sit / put the injured part in the pools and have ice & water put over me, then tuen on the whirlpool. stainless steel tubs like this.......COLD, very COLD.

Looks like the Chemistry Lab at my college...... We used the "air chamber" for very odorous chemicals
