TMY-2 Reciprocity

[max_barstow]

<p>Hi,</p>

<p>I want to do some photographs at night; I shoot TMY-2, and develop in Xtol 1:1 for 9mins (all very straightforward). Can you advise me on how much I'll need to compensate for longer exposures? I'll be shooting around the City of London (financial district), so there'll be plenty of street-lamps and light sources etc., so I doubt I'll need any crazy-long exposure times. While I'll take advice on alternative film-dev combos, I'd really rather stick with what I know (and like).</p>

<p>Thanks, Max</p>

<p>For what it is worth, Fuji Acros has excellent reciprocity characteristics. You don't need to compensate at all up to 2 minutes, and then just a half a stop for up to 17 minutes (1000 seconds). It also does really well in Xtol 1:1. You should be fine with TMY-2 though too...it is an amazingly good film. </p>

<p>Go Xtol 1+2 or 1+3 (full amount of developer but half as many rolls per tank) for slightly lower contrast . Have fun and bracket a lot (towards longer times). And weigh down your tripod!</p>

<p>I would at least look at the right pdf for TMY-2:<br>

<p>It's quite possible that it has better reciprocity behavior than what is listed in the PDF. I don't think Kodak updates that stuff very much. That being said, for 10-30 second exposures, you're probably just fine with no adjustment.</p>
