The segment(Luminous Landscapes) where Michael and guests sit around the table and comment on a portfolio of images is really really helpful. The free ranging discussion by the image maker and visually aware photographers was fascinating.
I was a "visually aware photographer"? Phew...glad I didn't stick my foot in my mouth in that review. ;-)
As for being helpful, you should try being actually in such a review. Amazing what it has done for my images, and even more so, my printing of them. Highly recommended.
