I have just tried snappy snaps this afternoon. The quality is not satisfactroy. Can you recommend a high quality film processing store in London? Many thanks.
diemaus, are you using colour negative film in 35mm only?
Snappy Snaps is a franchise, so the quality is only as good as the owner and/or operator in that particular shop. I've heard good reports about them, so it may be worth trying a different branch.
Other than that, any large branch of Boots the Chemist is worth a try. There will be loads of others but Snappy Snaps and Boots are all over the city.
