one more time ...;-) Tri-X and d-76/d-23
Hi everyone !
I have few hours to train and loaded tank in backpack. Digging thru archive. Looking for good times for tri-x 400 rated between 400-800 (d-23) - wedding and 800-1600 (d-76)* - wedding party. I'll probably find something, but if anyone could rescue me with some advice, I would be very glad. I'm not looking for book, but short instruction like tri-x 400@1600 in d-76 1+1 13 min std. agitation ;-) Best regards, First time user of tri-x Martin * in fact, d-76d |

Not that it is a bad film or anything, but if the images are important and cannot be reshot, you should use the film you _already know_, the film that you have calibrated, the film you can predict. BTW, in any case, if it is a film you do not know and have not calibrated, in my experience you should shoot it at about 1/2 the box speed (in your case, at EI 200), not twice the box speed which will present you with challenges that you do not wish to meet when shooting something non-repeatable such as a wedding. Why two different developers. Use the developer you already know, too. -- .~.

Why two different developers. Use the developer you already know, too. Now that Jean has told you not to do what you're already in process of doing... For a one stop push, you'll usually need to extend development around 50%; for two stops, you'll need to double it. If you were in the United States, I'd recommend shooting the whole deal, wedding and party, at EI 1250 and developing all the Tri-X in Diafine. Failing that, the Massive Dev Chart shows 9.5 minutes in D-76 for EI 1600, or 13.25 in D-76 1:1; for D-23, they give times only for EI 400, 7.5 minutes in stock or 13 in 1:1. I'd personally recommend shooting it all at the same speed (reduces chance of errors) and developing in D-76 in preference over D-23; D-23 is a speed losing reduced contrast developer, and pushing film raising the effective speed by increasing contrast -- seems incompatible. I haven't done either of these processes myself, BTW, I'm just reading from a chart that's usually pretty accurate. I use Diafine for Tri-X when I need more than EI 400 -- but I'm well aware it's almost unobtainable in Europe (not sure why; it ships as dry chemicals and is no more hazardous than other developers). -- The challenge to the photographer is to command the medium, to use whatever current equipment and technology furthers his creative objectives, without sacrificing the ability to make his own decisions. -- Ansel Adams Donald Qualls, aka The Silent Observer http://silent1.home.netcom.com Opinions expressed are my own -- take them for what they're worth and don't expect them to be perfect. |

I would not wish to jump out of an aircraft with a parachute (which I have never done before), and an instruction book in my hand on how to work one. -- .~.

I wasn't a photographer there ;-) Why two different developers. Use the developer you already know, too. I know both; why them? 1) i have those powders right now 2) d-23 for its grain. EI 800 is one-stop push (not much in "one-stop-less" dev. It's gonna be an experiment. And i don't like to shoot walls and charts for experiments - I can't feel them, you know what I mean? 3) d-76 is one of my favourites, better then previous for pushing, one of my favourites. But I know it with ilford and foma, not tri-x. I've checked Kodaks technote and digitaltruth and probably will use their times. Anyway, thanks for good advice - maybe someday I calibrate myself ;-) Best regards Marcin (Martin in polish ;-) |

He has only a few hours (from 06:24 this morning) to calibrate the
new film and developer combination. To become familiar with how to print the resulting negatives, and then go? one moment, I'm leaving enlargener in home ;-) Why did the O.P. pick such an inopportune time to switch film? Why should he not use a film-developer combination with which he is already familiar? beacause it was only b&w film availble, eventually, i could use superia or gold or ProFoto. Hmmm, why not use tri-x.... I'm also reading charts in a moment (between mails) and have some ideas. Just thinking that someone have some good tested combinations and could write me why and how ;-) btw. I love this suggestions "use Diafine". maybe somebady could send me a package and I see is it worth of this? |

If you don't have time to test anything shoot Fujicolor 800 (much easier to
find color film everywhere) and let the lab process it. You can make very good Black and Whites by a number of different methods from the resulting color negatives. BTW if you want to test Diafine, do what the rest of us do, buy your own. -- darkroommike ---------- "marcin" wrote in message ...

Does anybody know how to buy Diafine in Europe or which seller/shop send me package to europe? best regards Martin |
