I've also heard that having film processed by places like Walmart or the local Kodak shop tends to give poor quality photos?
I think that's a bit of a bum rap, but it certainly increases the chances of bad work.
I use minilabs regularly, being cheap, and can offer a few tips to increase the odds:
-Forget equipment hangups. If properly maintained all labs will have good stuf. It's the tech that makes the difference. Ansel Adams made masterpieces from what today would be considered junk machinery. A minimum wage kid who works photolab 1 day a week and has been doing it 3 weeks can't turn out a masterpiece from state of the art stuff.
-Whenever possible drop stuff off early in the day. People are more rested. Chems are fresher. Things just seem to work better.
-If they have 1 hour but you won't be back for 4 hours let them know. In this day and age of consumerism where people think they can come in to a 1 hour lab with 28 rolls of film from a 2 week European vacation and walk out in 1 hour...well when someone is the rare customer saying "Take a little longer, I'd rather have it right..."is probably going to make people at least a little more conscientious(sp?) on your job.
-If you have none mainstream photos...the Moon, comets, fireworks, Christmas lights, heavily backlit subjects, disclose it going in. You can take multiple stabs at printing a neg but only 1 shot at properly developing it.
-If you shoot a roll with problem lighting then finish out the roll. Don't take in a roll with 6 photos from mountaintop snow skiing in bright noonday sun along with a peck from kids running inside with only built in flash and some more taken on a Moonless night of the Orion Nebula.
-When you find a good photofinisher that works for a good price ask if you can get their schedule or remember what they look like. Another person at the same lab may or may not produce their results. If your developer is off today ask for next day and that developer. It makes them look good to the boss and more likely to give your film the best effort.
-Locally Click Camera offers superb processing in 1 hour at prices a shade below the typical minilab. The real deal however is if I drive 10 minutes farther to their main lab I can get up to 3 rolls back in 1 hour while the local Click minilab struggles to make 75 minutes. Now that the time is about a push I also know everyone who works there and their work is
EYEPOPPING!
-Another deal I had once, a guy who ran the darkroom for a local magazine publisher for 40 years retired and then just to get out of the house took a part time job working the minilab at a local Krogers. Dirt cheap processing, pro lab quality, and if you would listen they guy would educate you on nuances of color and shadow.
-Don't discount mail order. I still use York now and then. I used them a lot when I was younger. Other than a little more dust than Click they do nearly as good a job for almost free. They sure aren't Instamatic though. Younger people may not have the patience. Those old enough to remember being excited when the mail man came everyday, because their was no UPS-FedEx-1 Hr Everything, can probably deal with it.
