Large Petzval Lens
May 12, 2015
I was trying out the big Petzval. It is such a bright lens that I needed to wait till after sunset in the shade to take photos. It is too big for my regular ND filter, so I'll need to get a bigger ND filter. It doesn't quite cover 9x11 inch. My flat-field correction made the corners bright where they would typically be darkened.
