Hiya, I'm very new to film photography and have only developed a few 35mm colour film rolls shot with an Olympus XA. The first two roles turned out lovely, I had them developed at Jessops. With Jessops closing down I brought another colour roll to some Kodak Express shop (£12 a roll, geez!!) but they all turned out very grey-ish and dull. I know there are probably dozens of reasons how this can happen, but is there maybe a common mistake that causes this dullness? I had a look on google but couldn't really find anything about it. Or can this come from developing the pictures wrongly? I could more or less fix them in photoshop but then that's not really the point of analog photography... Also, are there any shops you can recommend for developing films in the UK? Cheers!
