To get out of the ordinary and be more creative pictures, I recommend this device. All you need is a reflex and a remote control for example. Make the focus on the ground, the reflex is fixed on the monopod, monopod is slightly tilted and triggers the remote control to take pictures. Sure, we must make a score to get one good photo. But we get a picture for the top 4 meters. Example, in an alley, we see the balconies, it looks like we are about 4 meters high. Ditto for a wedding, shooting dancers to 4 meters. Ride, one can photograph the gardens etc ..
I highly recommend it, because this device brings a creative aspect for photos.
