A complicated way of taking lots of poor pictures. There are a few reasonable shots in the Portfolio, but most are dull to say the least.
Interestingly I saw a similar drone out shooting pictures along the local seafront at Milford on Sea (UK) after a terrific storm had lashed the area destroying many concrete beach huts. It led me to think that there use will probably increase dramatically in the next few years - this was a private photographer as far as I could tell. It will be interesting to see how quickly they are constrained by law.
