Dear Pavel,
Does one have to ask for special processing if XP2 is exposed at 800 ? How about 1600 - is that a ruined roll?
No in both cases -- but the 1600 will be pretty marginal. A lot will depend on the subject and the metering.
How remarkable a difference is it to shoot HP5+ at 1600 versus Delta 3200 at the same speed? I'm really interested in the details on that question.
The HP5 is pushed 1-2/3 stops from ISO 650 in DD-X, and the Delta 3200 is pushed 1/3 stop from ISO 1250, so it's LOTS more shadow detail.
Also how would you sum up the differences between Delta 400 and HP5+?
Tonality. My favourite description of HP5, courtesy of someone whose name I have unforgivably forgotten, is 'Like Casablanca. The film, not the place.'
Thank you once again for the help. I had gotten a subscription to your site last year and read it often. It is fantastic help.
Thanks for the kind words -- and for subscribing!
... Oh ... and .... I have been using a wide variety of films all this year. That is how, slowly, I've arrived at the decision that I will now shoot almost exclusively B&W and that is how I noticed how cramped iso 100 has been for me. Every time I load a roll of slower film I wind up wishing I could change the iso part way through. So iso 400 and up now ... so I can refine my knowledge.
Have you considered faster lenses? I regularly use f/1.4 and f/1.5, though I find f/1,2 and f/1 a bit too fast for many applications (zero depth of field).
I'll heartily second Don's advice not to place undue faith in anyone; the advice above is given on the basis that you have to start somewhere. I'd add, too, that it's usually a good idea to start as near the mainstream as possible. Beware of those who swear by film coated by Romanian virgins at full moon, and processed in a mixture of adder venom and humming-bird blood, because a lot of the time, they're getting good results despite their materials, not because of them. This is one reason why I might disagree with him about looking at what people have 'on the wall', at least on line. Another is that by the time it's been scanned and shown on a monitor, many a good picture loses its charm, and many an indifferent picture looks undeservedly good.
One more thing: a good local minilab will very seldom lose your films: I assume your problems were with mail order. BUT, most minilabs use a stabilizer, not a water wash, so the stability of the negs will be compromised unless you request your films uncut and re-wash at home. Then again, it's amazingly easy to process C41 yourself with a CPE-2 (silly-cheap second hand), and with chromogenics you can also give a slight push if you feel like it.
Cheers,
Roger
