Mastering Long Exposure The Power of Neutral Density Filters

This video is a deep dive into long exposure photography, which of course goes hand in hand with the neutral density filter. 0:00 Introduction 0:26 What a neutral density filter does 0: 45: Listing the situations I might use an ND filter: 0:48 Blurring water or clouds 0:55 Vehicle light streaks 0:58 Blurring people in motion 1:01 Panning 1:08 Paint with light 1:13 Photographing in bright sunlight at wide apertures 1:42 Blurring water or clouds - tips and tricks 2:10 LIght streaks from vehicles - tips and tricks 3:17 Combining light streaks with twilight captures in Photoshop layers 3:30 Blurring moving people - tips and tricks 3:49 Panning - tips and tricks 4:12 Painting with light - tips and tricks 4:33 Painting with light - Combining multiple exposures in Photoshop 5:24 Photographing with wide apertures in bright sunlight, syncing flash 5:50 Getting creative with Photoshop layers and combining captures with different shutter speeds 5:54 Behind the scenes on a long exposure plus flash portrait shoot 6:26 About Stefan Roberts, pinhole camera expert 6:56 The basic technique behind the portraits 7:18 Types of neutral density filters 7:24 Variable neutral density 7:39 NISI 100mm square filter system, combining with NISI circular polariser 8:13 Potential light leakage with the NISI system 8:35 NISI system doesn't come with a sun hood 8:49 Advice if buying ND filters 9:34 Graduated ND filters, and why I don't use them 10:23 Calculating correct exposure when using ND filters 10:34 The NISI phone app 10:38 The Photopills phone app 10:48 Filter density rating systems 11:11 Two other essential items: A tripod and a remote release 11:32 Using mirror lockup to avoid camera vibrations with a DSLR at slow shutter speeds 11:48 Conclusions and summary https://www.stefanroberts.co.nz/index NISI phone app: https://bit.ly/3OzbBoh Photopills phone app: https://www.photopills.com/ ND Filter Notations 1. Optical Density (OD) • This is a logarithmic scale where each increase of 0.3 in optical density corresponds to one stop of light reduction. • For example, an ND 0.3 filter reduces light by 1 stop, ND 0.6 by 2 stops, and ND 0.9 by 3 stops. 2. Filter Factor • The filter factor represents the multiple by which the light is reduced. • An ND2 filter, for instance, reduces light to half its original intensity (1 stop), ND4 reduces it to a quarter (2 stops), and ND8 to an eighth (3 stops). 3. Stops of Light Reduction • This is a straightforward way to express how many stops of light the filter reduces. • A 3-stop ND filter reduces the light by three stops, allowing for longer exposure times or wider apertures in bright conditions. 4. ND Number • Sometimes expressed as a three-digit number following “ND”, such as ND400 or ND1000, indicating the factor by which the light is reduced. • For example, an ND400 filter reduces the light to 1/400th of its original intensity, roughly equivalent to about 8.65 stops.
