I rang them today and had a long chat (possibly worryingly long; I felt he was telling me stuff I didn't ask, not letting me ask what I wanted to know... and didn't he have work to do?). Anyway, they are apparently a bunch of wedding photographers who shoot weddings on film (hey there
@gazmorton2000 !), and for various reasons weren't happy with the services around and decided to set up for themselves. They have Fuji Frontier (or Frontera?) scanners. I wanted to know the scan resolutions, and I got this pitch that it scans at 300 dpi for a maximum of 12" width/length... I think he was saying that it scans at the resolution necessary to print at 300 dpi, and prints a max of 12". Hence the maximum scan is 3600 * 3600 pixels. That translates into about 2400 ppi for a 35mm scan, I think (1" by 1.5" approx). For 6*6 cm (or 2.25" square), it should max out at a bit under 1800 ppi. There were various caveats that I didn't understand, so treat this with a lump of salt at the moment. He did say they scan their own stuff at medium density, and it will actually print up much larger if you take the TIFF and work it in Photoshop.
Anyway, I've ordered 5*135 and 1*120, all scanned at medium, £5 per film, no return delivery charge, but I pay postage there (gone up to £3.30 these days, for first small packet). (Small scans would be £3 process and scan, large scans £8 I think.) They will call me when they get the films to discuss my requirements. They will post me a link to some small, un-sharpened, highly compressed scans, via something called "WeTransfer". When I've had a chance to look at them, they call again and we discuss... something, not sure, maybe whether I want TIFFs or JPEGs, larger/smaller, tweak the colour balance, sharpening, not sure yet. From what I can see, payment happens after rather than before processing. Again I'll tell you later. Then they post back a CD with the negs and scans. They can work out a profile with me (not sure he called it that), maybe like UK Film Lab does. As an example, he said one user felt his Portra was coming in with a slight magenta cast, so they add a hint of green to his scans to balance it out.
They cut into 4-neg strips, no filing punch holes, something about a supply problem. If you ask (I forgot!), they can cut into 6-neg strips (which they also prefer), but they'll have to return them in 120 sleeves, presumably a bit loose. Again no filing punch holes. I guess the idea is to re-sleeve them for your filing, ready in case you need to scan again. I can't argue too much with all of this, as my favourite C41 lab, Photo Express, does 4-neg strips, and I've only just started being bothered. But trying to get into a better filing regime, the lack of punch filing holes is a PITA.
