I love my Polaroid SX70, but it comes with a weakness.
It doesn't have any flash and it uses 100 ISO film packs.
This means that shooting in low light is challenging. A tripod is a must and given the long exposure times I have to ask my models to stand perfectly still while the shutter is open. 
This is uncomfortable for them and rarely gave the desired results in terms of sharpness, because nobody can stay perfectly still.
So I decided to embrace my camera limitation, to work around it and use the weakness to convey a message.
So I asked my models to simply move. Simple as that.
