This picture was taken on my iPhone 7 Plus. I used the portrait mode, lying on my front on the concrete jetty.
i was photographing my Canon 6D on my Manfrotto Pixi tripod - my lightweight travel kit. I left my Platypod Pro in the room this time as I also use the Manfrotto Pixi as a handle in low light, as well as jamming it on all sorts of things (one being a crash barrier on this particular morning).
I had a thought. I wanted to blur the background, so tried the portrait mode on my iPhone camera.
And this is the result. Not perfect granted, as there is a colour shift across the image, but it does give the effect I was looking for!
