After using FilmProcessing to develop and scan the vast majority of my film rolls, both B/W and C-41 types, I feel like I have enough experience to confidently give these people a genuine 5 star rating, and I can't ever see myself using anywhere else as my 'main' developing and scanning place.
I tried FilmProcessing after a dissapointing experience at another photo shop which almost put me off photography, and honestly I have yet to have any complaint with anything they've done.
Sending film rolls in is extremely easy, I do mine wholly by post with their printed form, because that's just the routine I have, but you can submit the order online (and you do get a LOT more options for types of film such as souped film etc) and post it; I assume most people do it the latter way.
Turnaround time for colour C-41 film development and return is usually around 3 working days from postage, sometimes a bit quicker depending on your order, B/W film was about 10 days, but given the way B/W is developed this is a pretty decent turnaround.
All of my orders so far are requested to have 6x4 gloss prints with all the photos digitized to CD and at no point has their packaging been a problem, there is very clearly a lot of care that goes into it (even the CD has its own inlay card telling you what's on it), the prints are, again, a really good quality and the negatives have always returned in a nice plastic sleeve with no damage. The scans themselves have always come out great, with no real concern regarding quality or colouring,
Plus, it's a local Plymouth business which is great for me as I live in the area and its nice to support something local, but even if it wasn't, I'd probrably still be using them as regularly as I do now.
