1. High contrast pictures can be achieved a number of ways. Lighting alone can be a major factor; if its a cloudy, overcast day vs. bright sunny day at noon, the first will naturally be much less contrasty (because of the diffused light), and the latter will be naturally more contrasty (direct light creating sharp/more shadows). You can also try faster film (as Civil_Disobedient suggested, though I haven’t had the best luck with tmax 3200), or push processing (a quick google search should yield helpful results, or I can explain it if you’d like, as this is what i do about 95% of the time with my film). Or, as galaksit suggested, you can use screw-on filters on your lens. 2a. The best way to make the best of them now is to use filters when you’re printing. 2b.
