Do you use one? Can you recommend a system to me?
I understand that with the screw on filters you are stuck with the horizon in the middle, which is not ideal. That leaves the funky rectangle ones - Cokin and Lee.
Can anyone recommend from use which is better?
My landscape photography has been limited (as are my skills for it), so any and all help is greatly appreciated. I would really like to take more photos outside, as Thailand is an amazing place, but am sick of blowing out the bright SE Asian skies. 
Thank you!
