Hey there, Long time reader, first time poster. I recently filmed an engagement session, and wanted to achieve a shallow depth of field in bright light without using an ND filter. So, knowing that I would end up slowing the footage down to about 40%, I cranked up the shutter speed in order to hit around f/2. The results? Well, see for yourself:
