I watch video tutorials for Photoshop as well as a few other products every now and again and last night they were using Tonality Pro to create "dynamic black-and-white images" in conjuncture with Photoshop. I had never heard of it before so I researched and found a company called Macphun that offers a lot of different software for editing but seemed a little pricey.

Has anyone ever used/ purchased anything from this company or heard of someone else using it? I want to give it a shot but $70 to buy something without recommendation seems a little steep.
