just another sample of Big Stopper use … the use of the ND filters can help to create different effect or mood of our pictures ….
many may ask how we going to use ND filters or Big Stopper as it is almost total dark ..
1. use GND/RGND or shoot like normal but capture the shutterspeed, ISO, F number… e.g below. but make sure set to Manual Focus after the capture or record of the setting
2. use the same ISO, Aperture but then convert the shutter speed base on 10 stops filter exposure table, ‘long time’ (for Iphone user), ND Calc (for Android user)
e.g. ISO100 , F16 , 1/30s before ND1000 , Big Stopper…. will change to
ISO100, F16, 30s
– DO NOT change setting ISO, Aperture
– DO NOT change focus (after the MF)
3. few notes need to be taken
– white balance could be run, you may correct it with white balance tool at Photoshop, Lightroom, DPP … by click white color spot
– the light condition could be change e.g. sunset .. it will change to darker so need to compesate with some add on time … e.g. 30s above I normally add on 10-20% time for sky getting darker
– sturdy tripod need to be use avoid shake …
– long exposure noise need special process to remove (color noise) , if do not know any method turn on long exposure noise reduction
