This gallery of uncorrected neutral-density filter test shots has four sets of shots with four images each, the first in each set having been taken with a bare lens (no filter) and then three different deep ND filters. Here you can see the raw colour rendition of each filter, all being significantly different from each other. The suffix on each filename will tell you which filter was used as follows...
-No suffix means no filter of course!
-FHF: Formatt-Hitech Firecrest 16-stop IRND
-BW: B+W 10-stop ND (110 ND 3.0 - 10 BL 1000x)
-TA: Tiffen Apex XLE-series 10-stop IRND
The camera (my Fujifilm X-E2) was set to daylight WB and no colour or exposure correction was done after in Adobe Lightroom. The 'IRND' designation on the Firecrest and Apex filters refers to the fact that they also filter out infrared light, which can sometimes affect the colour balance on long exposure shots with very dark ND filters. Please see the accompanying blog posting for more details...
