Photography podcast #130 reviews the Big Stopper by Lee filters. The big stopper is a 10 stop glass filter that slows down shutter speeds in order to accentuate movement. Both clouds and water are classic subjects for use with this filter and the resulting photographs tend to be ethereal and dreamy. Aside from reviewing the filter, I offer up 6 tips on how to use it effectively.

This evening image of Rue Laurier in Montreal is a long exposure image using the big stopper. You can see movement in the clouds, and in the cars. The people look ‘ghostlike’ because they moved (somewhat) in place while waiting for the traffic light. Notice the traffic light has all 3 colours lit because the traffic light cycled during this 30 second exposure. Exif data — ISO 100, f/11, 30 second shutter speed.
Fast moving water at Chutes Dorwin in Rawdon, QC. Canada. In the top image I used my lowest ISO (50) with my smallest aperture (f/32) and this yielded a shutter speed of .4 seconds. The water does look dreamy. But when I used the big stopper, I was able to get much slower shutter speeds and the lower image was exposed for 15 seconds. It’s much dreamier and more ethereal looking but the filter must be used with care. If you look at the top of the bottom image you can see a rainbowish arc and this where flare entered my camera. As discussed in the podcast, this is easily solved with a hat (or postprocessing).
Fountain at Parc Lafontaine in Montreal, QC., Canada — The slowest shutter speed I could get without a filter was 1/60 in this light. When I put the big stopper on, It extends the available shutter speeds big time. The image on the right was a 15 second exposure using the big stopper and look how dreamy the water looks.
