This video has been a real labour of love for me - I really hope you enjoy it / find it useful. I decided to test 10-stop filters as they are strong enough to have a good chance of giving you an idea of how other filters by the manufacturer might perform.

As mentioned before, each filter was a 67mm diameter ND1000 (10-Stop / ND3.0) model.

The colour tests and flaring tests were performed with a Sony a7R II camera in full-frame mode, in carefully controlled environments with pre-set white balance settings, to ensure fairness and consistency.

The sharpness test is taken from the center of the image frame of a picture taken on a 24-megapixel APS-C camera (Sony a5100) to put maximum pressure on the filter (the lens was set to f/4.5 for maximum sharpness). Each filter was cleaned meticulously and dusted before any test took place.
