G'day Joe,
Sounds like you've got it sorted. Here's just a couple questions I'd ask, which may be food for thought, or may be "nup, got it sorted", you know, so this is just 'brain-storming', I'm always looking to streamline my practices and am always willing to learn, so talking about all this is helpful for me too.
What I gathered from what you said was that at the end of a job you'd hand over all films, a CD of scanned images as well as any prints they ordered from you. After that, you're done and have nothing more to do with the client (unless they hire you again, of course). That makes sense, especially considering, as you said, peoples desire to DIY as far as their prints go these days. It sounds like a good practice and something that would work well for you. Here's how I would consider tackling it:
-As part of your agreement with your clients, I'd state that they are going to get at least a print or two from you. Whether they have to order them on top of the rate, or, just as goodwill, you include it in your flat rate (this is what I do at the moment).
-Provide your client with the CD of scanned images from film and the 'complimentary' (or paid for, depending how you do it) print.
-State in your contract with them that yo are more than happy for them to make as many prints from the digitized images as they like. From my experience, shop scans on CD are okay, they'll keep the casual observer happy at 8x10 prints, which is probably the most common wedding etc reprint size (in my experience anyway, it's sor of the 'classic' size).
-Also put in your contract that the actual films belong to you, as the photographer (one guy I have worked with has a statement saying he will release any negatives to the client after twenty years from the date of the event... last month he got his first phone call to get some negs back, he was very surprised... he said he had no idea how quickly 20 years can go by!). If your client wants to order further 'professional' prints (ie, from the negs) they can do so through you. That may never happen, they may be more than happy with printing their own from the CD, and you still have the originals to use for any future promotional work or advertising you need to do for yourself (if you've written that into your contract). However, if you have a more discerning client, they will see that their CD prints are okay for small snapshots and web use, but will see the difference in quality when compared to a proper print (Yes, there's a good reason to offer them a complimentary print, it serves as a reference point for their own prints). If it's colour work, a print from film through a pro lab will look really nice (hopefully you've got access to a good analogue lab? If not, a Fuji Frontier lab will probably still be quite good) next to the prints from their CD. If it's B&W they want prints of, and you're doing your own, you then have the advantage that these are hand made pieces of artwork, which they might like as something special to keep, even if they have printed the same pic from the CD.
Anyway, I hope that came together alright, it's the end of a long day here and I'm in a rush to get out into the sunshine before the clouds roll in again! Would love to hear your thoughts, like I said, it sounds like you've pretty much got it sorted in your own head, what I've written here may very well come under the "Nah, good idea, but not where I'm wanting to go" banner, in which case, GREAT! You've just ruled out one more variable in your business workflow and gotten one step closer to knowing exactly what works best for you in your situation right now.
All the best mate, hope yo ufind a workflow that works for you.
