Hermione says in *Goblet of Fire*:

>‘All those substitutes for magic Muggles use – electricity, and computers and radar, and all those things – they all go haywire around Hogwarts, there’s too much magic in the air.'<br><br>
><sub>*Goblet of Fire* - pages 475-476 - Bloomsbury - chapter 28, *The Madness of Mr Crouch*</sub>

and in *Chamber of Secrets* Colin Creevey says this:

>‘[A]nd a boy in my dormitory said if I develop the film in the right potion, the pictures’ll move.’ Colin drew a great shuddering breath of excitement and said, ‘It’s brilliant here, isn’t it?'<br><br>
><sub>*Chamber of Secrets* - page 75 - Bloomsbury - chapter 6, *Gilderoy Lockhart*</sub>

**How is it that Colin Creevey's Muggle camera works properly at Hogwarts and on the Hogwarts grounds? Further, how is it that a magical potion could create moving pictures from Muggle film, which only takes one-framed (for lack of a better description) shots at a time?** I'm assuming Colin's camera is not digital, as this is 1991, plus Colin, obviously, references film.
