Photographers love simple solutions to challenging problems. How many of us have saved a shoot with a strip of duct tape and a piece of cardboard?  

This three-minute video from COOPH shows seven clever photographic 'hacks' - from using an egg timer and GoPro for a panorama to creating a Gary-Fong style diffuser with a Tupperware container to creating a neutral-density filter out of welder glass and rubber bands. 

Some of these have been around for years - using vaseline on a lens for a soft blur effect was the staple of Hollywood in the 1940s - and just a few minutes is all it takes to see this collection of creative solutions. If one of these comes in handy on a shoot, then it's time well spent. 

What's the most interesting 'hack' you've created?
