35mm film/slides consumer garbage??
Perhaps you have it backwards... Consumer 35mm print film is garbage.. shipped and stored in uncontrolled temperatures, for who knows how long, made to wider tolerances, etc.
To make matters worse, auto-everything volume-lab printing is crap. Well, not crap, just set up to make passable snapshots from crap exposures on crap film, not great prints from great images on great film. They're also often set up to save costs by always scanning at 6MPixel, regardless of the intended print size.
Films like Provia, Portra, and even Sensia and Kodak HD (if you get them fresh) are really good. Processing is really good anywhere that the machine is kept clean and running properly and the chemicals are kept fresh.
Scanning the film yourself is the ticket, even with a cheap scanner like the Konica-Minolta Scan Dual IV (which I use). Once you have the exposure calibrated (use the strip at the beginning of the roll that goes from fogged to unexposed), set the whitebalance (just like with digital, have a photo of someone holding a white card in the same light), lock the settings and scan away. You've just made images far better than the minilab would make, assuming your exposures, composition, and subject matter is good.
From that point on, the images are just the same as images from a dSLR, except with more flattering contrast if shooting pictures of people with print film, and higher resolution for a given capital expense. When you interpolate to different sizes for printing, the grain seems to disappear from 400iso. Just like digital, you can print on your own inkjet, send them to a printing service (mpix or whatever) or take them to a minilab to get prints done. If you take them to the minilab though... tell them to do no corrections or they'll leave the machine on auto-everything and you'll get crap again (but this applies to any image shot with the camera on any mode but the most basic, film or digital).
Sounds like the rantings of a film zealot? No, if I were running a portrait studio (other than high-end), shooting sports, or photojournalism, I'd probably be using a dSLR for their lower cost per picture and faster results. Most of the techniques I use apply to either film or digital equally well.
