I have the variant ND1000 chosen because I want to work even in daylight and wide-open aperture. Of course it is possible to combine several filter - but that the use of various filter makes an image not necessarily better should also be clear. The ND1000 "swallows" 10 f-stops. Here's a quick overview of a few exposures with and without a filter for those who must first convert cumbersome.
1 / 1000s - 1s
1 / 250s - 4s
1 / 125s - 8s
1 / 60s - 15s
1 / 8s - 2m
1 / 2s - 8m
1s - 16m
It is so beautiful can be seen that the exposure also can be raised dramatically with ND1000 filter daytime.
The filter of Haida comes with a cheap cap which has migrated into the same drawer. The filter itself is meticulously crafted, the thread runs clean and scratch-free and despite the slim design, the filter can still draw well. The slim construction can take pictures even with fairly wide angle lenses without seeing the filter mount on the image.
The color cast, which actually occurs in all gray filters (of any manufacturer) is more bluish in Haida filters. A white balance directly to the camera (eg 9090 Kelvin as another review described here) can counteract the already very good. Alternatively, the blue tint can also subsequently rausrechnen quickly in eg Lightroom.
I am very satisfied so far with the filters and could already make some interesting photos so. I recommend the filter to anyone who wants to break into the topic Long Exposure. For the called price of around 30 euros, the filter is wonderful to go to the first steps in this field. I'll probably still buy in the future one or two other gray filter and thereby also very safe again pull the items from Haida considered.
Final Tip: For almost any smartphone operating system, there are now apps, in which only the strength of the neutral density filter and the exposure time must be entered without a filter. Then immediately is the time with filters available, you can adjust everything on the camera and saves sometimes convert the annoying.
