A Screw up that worked Tri-X 2 stop pull


Recommended Posts

<p>Well talk about a pull. I had a bulk roll of what said FP4+. I put it in the F100 set the meter to 125 and went out to shoot. Turned out it was a short roll so that means it was the last one from a bulk roll. I developed it in Xtol 1-1 for 10 minutes which is the time for FP4+. I hang it to dry thinking hey these look pretty good and then I see the edge rebates. Arista Premium 400. Yep it was Tri-X. Most of these are right out of the scanner. I did pump the contrast a little on a couple.<br>

<p>In fact like many users I call Tri-X a 200 speed film for most purposes, especially portraits. So calling it 125 is only 2/3 of a stop "pull" which is not unlike typical meter variability combined with different metering techniques.</p>

<p>I had to change my meter setting from 400 to 200 when I went from centre-weighted metering to matrix metering. It took me a while to realize that my metering technique which had worked so well in the past (meter pointing away from the sky, then reframing) was not so relevant to matrix metering which was trying to do all that for me.</p>

<p>Nice results. After the safety factor was reduced around 1960 Tri-X was officially rated at ISO 400, but many users continued to rate it at EI 200. Many users prefer the look. With scanner technology it's even better, I've heard (though I haven't tried the EI 200 rating since I got a scanner.)</p>

<p>Some of my friends are starting to call me All Luck Larry. LOL Thanks Dave. I am now wondering if the times for FP4+ with other developers is to be the same for this pull and look. Looking at the first scans then pixel peeping I could not help but think of Plus-X. Maybe this is another replacement for my lost friend Plus-X.</p>

<p>It is a little-known fact that negative films thrive on (moderate) over-exposure. The results are almost always better than under-exposure.<br>

Considering you used Matrix metering (which means the camera has used an algorithm to peg exposure),it is entirely possible you didn't overexpose much,if at all.<br>

Sometimes,the odds balance out in your favor. Enjoy, and try center-weighted next time.</p>

<p>Looks great, Larry. Sometimes I like to push my films and developers to extremes, just to see what happens/ where the breaking points are. I find film, in general, to be quite forgiving. </p>

<p>Here's an example of doing just about everything "wrong": I used Adox 25 for a portrait, I shot handheld in direct sun at full box speed, and I developed in a dilute, acutance developer with low frequency agitation. This is asking for trouble, right? But, I had a few tricks up my sleeve. First, I used my 150 SF-C lens, which turned the granite boulder into something like a wool blanket as it drifted out of focus, but I stopped down enough to keep my subject sharp. Second, I used Obsidian Aqua, a highly compensating developer, to check highlight density. I really like this combination, and I'm very disappointed this film is going away. <br>

<p>I just made nearly the same mistake. Put in a roll of Arista Premium 400 (tri-x) thinking it was the 100 (plus-x).</p>

<p>I used the Massive Development Chart recommendations for Tri-X at 200 in HC-110 (b) and reduced that time another 15 seconds.</p>

<p>The film came out way overdeveloped. I still haven't mixed up the Xtol. That'll teach me.</p>
