using the darkslide to protect when ejecting is something i do for my SX70's. my impulse has the frogtongue that covers the picture while it's ejecting. as soon as i can, i cover it up with my left hand and transfer it to my pocket asap. shielding doesn't seem to be an item with the new ColorProtection film though, but even for the original polaroid film, there was mention of not leaving it exposed to sunlight when ejected, i think. grainyness isn't an issue to me, because it makes the TIP-film what it is.
