I didn't realize so much work went into creating camera filters!

Anyone using graduated neutral density filters?
If you do, or if you are just curious, here is a video about how Lee Filters produce their
hand-made graduated neutral density filters. I have been using their high-quality filters for years
and for me, these are one of my most valuable photographic equipment when I do landscape photography. And no, I do not work for Lee Filters. Although there are several brands that manufacture graduated neutral density filters, this is the only video (that I know of) that shows in detail how Lee Filters make theirs. Well worth a look!Have a fantastic day everyone!
