Just had this idea while bathing.
It evolved from the idea of street shooting at chest or waist level using Wi-Fi remote composing and triggering. Is it feasible to hang the camera around the neck or strap around the body and use it as a support. Compose thru' the HP or tablet, then hold your breath, and remote shoot using the 2 second delay. Will this be more stable than holding up the camera using hands? This could be an alternative to the string tripod idea in the absence of a proper tripod.
Did a quick google, idea don't seem to have been suggested before. I wonder if this has been explored and discussed here or elsewhere?
