Well, if you're learning, slide film with teach you a little more about exposure and is cheaper than print film in the long run when it comes to per roll price and devleoping. I pay right now $8.75 a roll for developing 35mm slides at one pro-lab which is on the high side of the spectrum and the other lab I've recently had a bad run of luck at charges $7.50 a roll. There are places that chagre a little less but you get what you pay for as evidenced from the number of ruined slides I have.
At those prices, I have basically paid for a D70 and then some in the last 9 months.
Digital SLR's I think are the greatest tool out right now for learning. No financial repercussions for under/over exposing half a dozen shots to only get one good one. I just come from the previous generation that learned with film as digital just wasn't up to par 10+ years ago.
My suggestion right now for someone who wants to start learning with a full featured camera, go digital. With the current
affordable technology out right now, I'm of the opinion that film still has the edge when comes to quality but digital owns the world of verstility when it comes to convenience. But who knows what the next 5 years will bring. I just go with the flow which has me in a half film, half digi world, as I shoot film but scan em' for web use and the occasional 8X10 from
Adorama. For stuff I hang on the wall, you can't beat prints from slides................
disclaimer: When it comes to the Film vs Digi debate I can only share the opinion of Sgt Schultz from Hogan's Heros... "I know nothing......"
