A bit of a learning curve but this great product will enhance your images. If you have free time please check the Lee Filter website for tips on using. Adds the ability to shoot in high contrast situations such as full sun or when shooting reflective surfaces. Very high quality piece of glass and comes in a protective case. I plan to also add the little stopper to my collection.
I have been using the Lee systems for a while so know how to use them, but have never tried to make B/w photos. But, thx for the tip :)
