For all the advancements in camera technology over the last couple of decades, one of the easiest and most effective ways of dealing with adverse conditions and light is still the filter. Opening up all sorts of options when harsh light is a problem, as well as helping to deal with glare, there are lots of options available. A variable ND filter is always a good choice when filming in harsh lighting conditions, as it lets you open up the lens more for those shallow depth of field shots - hugely popular with many couples!
