I was out trying out my new filter, the "Hitech Pro stop 10", last sunday. Hopefully I was doing something wrong because it really didnt turn out how I was hoping.
I knew there were going to be some colour cast but i didnt think it was going to be this bad. I wanted a blue tone for this shot though so I guess it worked out ok.
Lack of contrast and vignetting were 2 other not so nice side effects. I managed to save some shots through some heavy post processing though. But not with any natural looking colours.
I will test the filter some more. Some light might have leaked in causing some of the effects so I will be more careful with that. Hopefully it will work out. Otherwise its back to the old trusty ND500 screw-in :)
If anyone has any experience with this filter, let me know how it is working for you.
