Is there anyone who can recommend a shop that develops and scans B&W and color slide film, 35mm and 120, producing high resolution scans (>~15 Mpix)? I've decided to give film another go. I'd prefer a place in the Boston area, or at least on the east coast. I can find shops on Google of course, but here I'm asking for the experience of UHHers.
I can't help you with local processors....
But for B&W film I'd recommend you consider using Ilfrord XP2. This is a chromogenic B&W film... dye-based and scans much better than silver-based B&W film. It also is developed using the same C-41 process as color print film, making it relatively easy and inexpensive to get processed. It looks rather low contrast, but that's actually a good thing when it's scanned. You can tweak the digital scan as you see fit to boost that, very easily. I love B&W films such as Fuji Neopan Acros.... but only when doing darkroom enlargements.... not digitally scanned.
The "problem" with standard B&W films is their silver halide crystals that make up the image (the "grain" of the image). "Tonalities" in B&W film are created by more or less of those crystals forming. When scanned, the silver halide crystals block light passing through. Plus, unless you plan to process the B&W film yourself, you will have more trouble finding someone able to process it... and if you do it will likely be fairly expensive to have done.
Dye-based B&W chromogenic film has tonalities are shades of gray and remain transparent, more or less depending upon their density. For comparison, think of different strength Neutral Density filters... shades of gray.... versus the half-tones made up of dots that newspapers and magazines use to print B&W photos.
Ilford XP2 (ISO 400) is available in both 35mm and 120 rolls. If you plan to scan B&W film, I'd suggest you give it a try. There may be some other chromogenic B&W films, but XP2 is the only one I'm aware of presently that seems to be pretty widely available.
When it comes to scanning, if you are serious about it I would recommend you pick up a quality scanner and do it yourself, rather than rely upon the film processor. Let the film processor provide smaller, low-cost scans from your negatives to serve as "proofs", but don't expect them to have anywhere near the quality or resolution you will want with your best images. Just use them for selection purposes, similar to how you might use basic 4X6" prints or "contact" sheets. High quality scans are available, but they're expensive. Similar to C-41 processed color print film, chromogenic B&W has a lot of exposure latitude (it's far more "forgiving" than slide film).
Slide film I wouldn't bother having scanned by the film processor. With the 35mm, just get it processed, have the slides mounted and returned to you. If shooting medium format transparencies, you'll probably want to get those as film strips, unmounted. Simply use a light box and a loupe to review your transparencies directly. Then scan your selections. Most slide films work fine for scanning. With slide film I always tried to keep to ISO 200 or lower, simply because the higher ISO slide films seemed to get very contrasty. Much of the slide film I used was Velvia 50 and Ektachrome 100VS (the latter is no longer produced, I think). When I needed higher than ISO 200 color film, I switched to color neg film instead. It's been many years and I didn't do that a lot, so I forget what films I used.
For the best quality, I'd recommend you get a dedicated film scanner with a minimum of 3200 ppi resolution. I use a long-discontinued Nikon 4000ED (with 4000 ppi). At it's maximum resolution settings, it makes 130MB 16-bit TIFFs. It won't serve your purposes, though, because it only handles 35mm and smaller film formats. One of the key reasons I bought the 4000ED was a bulk slide feeder was available for it. I load that with up to 40 slides and let the scanner run overnight. High resolution scans take time... up to 15 minutes each with the old 4000ED... I imagine some of the newer ones are faster.
If I recall correctly, Nikon made a 9000ED scanner that was capable of handling medium format film (as well as smaller formats... but no auto slide feeder). That's a pretty expensive model, though. Nikon no longer makes film scanners. Plustek, Pacific Image, Braun, Imacon and a few others are making them, if you want to buy new. But, don't overlook used. A lot of people buy a scanner, use it to digitize their archived film images, then sell off the scanner when they're done. As a result, there's a thriving marketplace of older, but still very capable scanners.
There are some excellent flat bed scanners, too... such as the Epson V800, V850 and similar. These can do a pretty good job with medium and large format film. I'd certainly consider one of these for that, but would probably keep using the dedicated film scanner for 35mm film.
Regardless whether you get a dedicated film scanner or a flat bed scanner, the software you use with it makes a very big difference. Some come with proprietary software that might be okay.... But there are much better available. The very best scanner software is Lasersoft SilverFast AI, which is bundled with some scanners or can be purchased separately. (Note: There are different "quality" levels of SilverFast... LE, SE, Studio... you should compare these to be sure the version you're considering meets your needs well.)
If bought separately, the more advanced versions of SilverFast AI are very EXPENSIVE! SilverFast also is scanner-specific... It's not "universal", but is tailored for each specific model of scanner.
A more affordable scanner software that's pretty good is Vuescan. I've used it with my Nikon 4000ED and it works pretty well... But it's not as capable as SilverFast or the original software that was provided with the 4000ED. (The orig. s'ware no longer works... it's incompatible with later computer operating systems.)
So long as you overlook some of the weird translations to English, some pretty darned good info about most of the better quality film scanners can be found at this German website:
