I have a mamyia universal that I use for polaroids and they look better i think than the non full framed polaroid cameras the 6x7. anyway, i only use that for fun

I do weddings also and have a package that includes polaroid coverage of their whole day up til cake cutting or so, for that I use 2 instax's and about 50 pictures.
I have pix of the images and of how I display at the wedding, message me with an email and I can show oyu.
