So i was browsing through my raw files on Adobe Bridge and really realized how much i shoot wide open during the day, and that usually ends up maxing the shutter speed @ 1/4000. Which i know i can avoid by adjustments, but obviously i did not notice i was shooting that high of shutter speed on certain images. So who all on here uses a ND filter on a fast lens on a day to day basis? i am trying leaving the B+W 103 filter on the pana 25 1.4 which reduces 3 total f-stops. Now if you do leave a filter on the lens at day time , what filter would it be? I am thinking that I should buy the 106 (6 stop) or 110 (10 stop filter) for the 1.4 and run the 103 on the 1.8 lenses. just curious as to what others have found to be more useful for everyday usage of shooting wide open in bright daylight, or long exposures..
