Have these filters always with you, he is very narrow, quite scratch resistant and cheap. I use it almost exclusively for the record of waterfalls and dams seldom sometimes for light trails. So far I have had no problems with color casts, especially since I always take pictures with ND filter in RAW and then eh so that I like them at least once adjusted. Despite the slim design front also still fit filter. Necessary accessory is a timer, but at least one remote trigger with locking device, because the 30 second of my 600D are often insufficient and next mode is just the bulb mode and 4 to 10 minutes, I hold down any button.
In my opinion, the first choice for all ND freshmen and at the price you can not make all too much wrong. View So enjoy exposing and photos.
