As I got confused when using ND or gray filters when comparing transparency, shutter speeds or aperture levels, I have created a usefull table here.
Gray Filter Conversion Table
|Filter||Neutral density ND||Transparency||Extension of exposure time||
Longexposure shot of the Woudagemaal in Lemmer (NL). 1 minute 30 seconds exposure time. Clouds and water are extremely soft. Nikon D500, Sigma 18-35mm F1,8 DC HSM | Art, HAIDA Slim Pro II ND-Filter
Which gray filters do I recommend, what should you pay attention to?
I myself use gray or ND filters from HAIDA. The filters are of good quality, in the middle price range and completely sufficient for my purposes. In detail I use the series "HAIDA Slim PRO II Digital MC Neutral Grey Filters", because they are characterized by a small thickness and therefore do not cause shadows in the motive. In addition, the filters are more space-saving to transport than thicker models.
Very thin, therefore no shading and vignetting
No color distortion
Practical to transport due to end caps
Perfect to screw on and off, clean thread
If you want to use an absolute premium product and perhaps attach more importance to the coating than I do, you will receive very good, but also more expensive products with the grey filters from "B+W":
My first choice as a Lightroom alternative
I'm gonna do some advertising. I've been dealing with all kinds of image editing software for months, comparing a lot, testing a lot and finally choosing RAW developer and Lightroom alternative Luminar 3.
