First of all thank you for providing us with such a nice tutorial. I love the simplicity of the tutorial and how easy you laid it out. Instead of three thousand descriptions of things that I don't need (for example random details about your specific camera, you just said "this lens" and "this filter") was quite nice. You cut right to the point.
Additionally your simplicity didn't take away from the information needed; it was complete and step by step easy to follow.
The pictures are a nice addition making it even easier to envision.
***please do not pay attention to the stars, the critique is in what I wrote.***
