Simple to use but..

The quality for the final image, if you do it in black and white, is very bad because all the grays near to black become black and appears like a big spot also if you save your file at 100% quality.
Whithout this trouble the software wold be perfect.
P.S. I take my shot with a 6D plus a canon lens and edited by Photoshop cs6.
