I was asked for a photo of myself for a presentation that I'll be giving, any photo , I gave them one where I'm facing away from the camera, they didn't like it
So , I had this one taken with a voice operated remote control (my daughter) , to make it more interesting we used the 105 f2.5, I explained how to focus and use the focus confirmation dot and the arrows to turn the focus ring in the right direction. The first batch of images were all back focused ... I forgot to mention the dot has to stay on, for the second batch we only needed two images.
Since we were reviewing in camera she was fascinated how the lens had the PS blur already done! After my shots the remote control ignored my instructions and proceeded to take photos of plants, the dog and other things complementing the blur effect of every photo
