eric_dolphy Posted July 12, 2015 Share Posted July 12, 2015 <p>a newbie asks about developing 4x5 b/w in DD-X, four sheets curled with rubber band in a <br /> paterson system 4 (2 reel) tank</p> <p>how is the dilution determined for example developing two sheets one day<br /> and three to four another<br /> is the dilution ratio adjusted for the increased 'workload' or<br /> simply more of the same thx all</p> Link to comment Share on other sites More sharing options...
larrydressler Posted July 12, 2015 Share Posted July 12, 2015 <p>Once you dilute and develop the film it is called one shot and you dump it down the drain. You measure the amount you need to develop the film you have in the tank and then it is not reused. one 4x5 sheet is the same as one 120 roll or one 35mm 36 exp roll in surface area. </p> Link to comment Share on other sites More sharing options...
gnashings Posted July 12, 2015 Share Posted July 12, 2015 <p>Larry, I think you mean two 4x5 sheets? both those roll films contact print onto more less 8x10. not that it detracts from the main message of your answer</p> Link to comment Share on other sites More sharing options...
john_shriver Posted July 12, 2015 Share Posted July 12, 2015 <p>DD-X is a great developer, but it's expensive for just about any method of developing 4x5 film. That's why I use HC-110 for 4x5 film, and reserve DD-X for 135 and 120 film.<br> (And everyone is having math problems, a 4x5 sheet has one quarter the area of 8x10. A 36-exposure roll of 135 is also 80 square inches, as is a 120 roll.)</p> Link to comment Share on other sites More sharing options...
larrydressler Posted July 12, 2015 Share Posted July 12, 2015 <p>True OOPS 2 4x5.</p> Link to comment Share on other sites More sharing options...
john_stockdale2 Posted July 12, 2015 Share Posted July 12, 2015 <p>4 sheets of 4x5 is equivalent to 80 square inches as John above said.</p> Link to comment Share on other sites More sharing options...

eric_dolphy Posted July 13, 2015 Author Share Posted July 13, 2015 <p> </p> <h2 >HP+ and DD-X 4x5 processing for newbie</h2> <blockquote >from an old thread, someone noted:<br /><br /><em>I had a container made for dunking the 45 film while in the hanger, it is 3/4 in wide, 6 inches long, and 6 inches deep, it holds 13 oz of developer and when the hanger is in it, it comes about 1/4 inch above the top of the hanger, I develop one sheet at a time and it works very well. Measure the width of your two hanger set and and allow 1/4 inch, the same for depth and length. Pat</em><br /><br />casting about for a processing method, one sheet at a time, HP+ w/Ilfotec DD-X,<br /><br />one part DD-X, four parts distilled water, nine minutes at 20C<br />the quoted method seems okay but your pov is needed <br /><br />Q: does it seem too small an enclosure ? thx all Eric</blockquote> Link to comment Share on other sites More sharing options...
