The Tiffen ND Filter Kit are probably the filters I use the most. The Lee Big Stopper 10-stop ND is great, but unless I’m shooting in mid-day light, I’m usually using one of these.
I love teaching and photography... In that order. I feel that enjoying photography, and photo editing can get WAY too complicated. So my personal mission (and favorite thing to do), is to create education that simplifies the process of taking great photos, and how to edit them to get the results you’ve always wanted.
