brent_bousquet Posted January 16, 2017 Share Posted January 16, 2017 <p>I shot this on my Mamiya rz67 with the Sekor c 180mm lens tody and I just started to scan the roll and I am getting a lot of this shape grain. I dont mind grain but this is much larger than what id like. It was quite bright and I was using tri-x 400. Is it my agitation or something else do you think.</p> Link to comment Share on other sites More sharing options...

AJG Posted January 16, 2017 Share Posted January 16, 2017 <p>It looks like reticulation, which is usually caused by an abrupt temperature change in processing or washing. Make sure that your wash temperature is close to your processing temperature--not exactly the same, but within 5 degrees F.</p> Link to comment Share on other sites More sharing options...
John Farrell Posted January 16, 2017 Share Posted January 16, 2017 <p>That looks like reticulation - caused by thermal shock to the emulsion, when its soft.<br /> <a href="https://www.ephotozine.com/article/create-reticulation-when-film-processing-4639">https://www.ephotozine.com/article/create-reticulation-when-film-processing-4639</a></p> Link to comment Share on other sites More sharing options...
peterbcarter Posted January 17, 2017 Share Posted January 17, 2017 <p>What Andrew and John said.</p> <p>What I do about it is I have 2 20l spigoted water jugs (Walmart or wherever) filled with tap water, hanging around my development area. It keeps the water at the same temp as my developers. I use this for wash and mixing of one-shot stuff. </p> Link to comment Share on other sites More sharing options...
brent_bousquet Posted January 17, 2017 Author Share Posted January 17, 2017 <p>Thanks I will keep that in mind when I do another roll tomorrow and see if it makes a difference. I was going to do both rolls tonight but now im glad I didnt.</p> Link to comment Share on other sites More sharing options...
glen_h Posted January 17, 2017 Share Posted January 17, 2017 <p>I keep club soda bottles filled with water. In the winter, my darkroom gets below 60F or 15C.</p> <p>As far as I know, reticulation occurs when going from a warm bath to cold, not so much </p> <p>After fix, I fill the tank with water at close to fix temperature, and then put the tank under the sink, with the water on low. If the temperature is different, it will slowly (enough) mix with the water in the tank. </p> -- glen Link to comment Share on other sites More sharing options...
brent_bousquet Posted January 17, 2017 Author Share Posted January 17, 2017 I think my problem came from running the water out of the tap after it was fixed and not checking to make sure it was close enough to the right temp. I just sort of know where about my knobs need to be to get a close temp but I think someone ran our dish washer which used up the hot water. I will get some jugs though that's a good idea.

Bill Bowes Posted January 17, 2017 Share Posted January 17, 2017 <p>Hello everyone. K.I.S.S. is a great idea. Left panel shows my Igloo developing set up. Cold or hot water to set temps if needed. Enough liquids for (2) 135-36 or one 120 roll. Right panel shows my Igloo set up for lugging the RB-67 cameras around. One per Igloo and they survive commercial flights to Hawaii every year. Aloha, Bill</p><div></div> Link to comment Share on other sites More sharing options...
kaiyen Posted January 17, 2017 Share Posted January 17, 2017 <p>I do what Peter does. I have 1 big jug with a spigot on it that has water at roughly the right temperature. This is enough for me even when I go on a developing binge. </p> Link to comment Share on other sites More sharing options...
rick_jack1 Posted January 19, 2017 Share Posted January 19, 2017 <p>"That looks like reticulation - caused by thermal shock to the emulsion, when its soft."<br> Think he nailed it.<br> Keep everything the same temperature to the 1/2 degree even the washing. <br> If you haven't already tried it, try a roll of TMY400 in TMax developer, it has no grain compared to TX.</p> Link to comment Share on other sites More sharing options...
brent_bousquet Posted January 19, 2017 Author Share Posted January 19, 2017 <p>thanks ill give it a try. i just really started to shoot film so i havent shot on that many different types. wanted to get my process down first so I dont ruin a roll i really liked. </p> Link to comment Share on other sites More sharing options...
glen_h Posted January 21, 2017 Share Posted January 21, 2017 <p>Last I knew, the suggestion was to keep within 5 degrees F, or about 2 degrees C, between chemical steps. 1/2 degree is pretty hard to do. </p> -- glen Link to comment Share on other sites More sharing options...
