I've been getting more into landscape photography lately and have primarily been using a Marumi 77mm Super DHG Circular Polarizer. I've been very happy with the polarizer, but some shots find the difference between sky and foreground forces me to either apply a fair deal of shadow / highlight adjustments or use gradient functions in PSE 10.
I'm interested in starting to use rectangular graduated ND filters.
I've done some research and found that the top of the line GND appear to be Lee and Singh Ray. Other options are Cokin and Hitech.
Cokin filters don't seem to be received that well in the digital era due to magenta color cast. Lee and Singh Ray are very well received, but also nearly $100 a piece.
Hitech seems to be in the middle. Reviews generally appear to be favorable with most saying they have good sharpness and no offensive color cast. They are also fairly reasonable at ~ $33 in the Cokin P mount. My plan would be to pick up the Cokin P Wide Angle mount if I went Hitech.
My question is would the Hitech filters do a good job for me or would I want to upgrade a short time later? Does anyone else here use Hitech? I know many buy the Lee system for the Big Stopper. If I were in the market for a 9 or 10-stop ND filter I'd probably opt for a screw on filter like the Hoya X400 instead of rectangular filters.
Thanks
Dave
