ramiro_aceves Posted May 21, 2003 Share Posted May 21, 2003 Hi my friends. In order to compare D-76 and ID-11 keeping capabilities and strenghts, I have done a test, this is the part I of this test. I have mixed stock solutions, for each developers, using distilled water and dividing the stock in four bottles filled to the brim, two glass and two plastic. This first test was made one day after developers were mixed, to let them stabilized.The film used was Ilford HP5+ in 35mm format. Exposure index was EI 280. A white card evenly lit was shoot to get zones from 0 to X. Development time was 9 minutes, with 5 vigorous inversions/minute agitation, using the plastic bottles. The results are very close, but it seems that ID-11 develops to a higher contrast than D-76, so, If there were not errors, I would say that they have not got identical properties as we always asume (that whould require more tests to apply some statistical confidence tests, but no time and money to do that). Indeed, when I mixed stock solutions, they have different smells. Well, this is the end of part I, part II will come after one or two months, will see wich one keeps better, and if plastic bottles work worse than glass ones. I will let you know. I hope you liked this test. Enjoy! Ramiro. Link to comment Share on other sites More sharing options...
conrad_hoffman Posted May 21, 2003 Share Posted May 21, 2003 Just to confirm, these were both the commercial packaged versions, not mixed from scratch? Link to comment Share on other sites More sharing options...
gary_frost1 Posted May 21, 2003 Share Posted May 21, 2003 Being a D76 user I truely appreciate all the testing and trouble you are going to and that you are sharing your data here on photo.net. I look forward to your installment on this test in about a month. Thanks Ramiro! Link to comment Share on other sites More sharing options...
rayfc Posted May 21, 2003 Share Posted May 21, 2003 Ramiro, Great idea ---Much thanks for the effort you put into this. I, for one, appreciate it and certainly, others do too. D76 (1:1) has been my staple developer for decades. I played with XTOL for a couple years and now, am learning to use PMK (for about 5 months now). PMK seems to be a remarkable developer... Anyhow, I look forward to your D76 test results as, after all these years, I only mix what I need and use it one-shot. Maybe this old dog will learn a new trick.

garry1 Posted June 24, 2003 Share Posted June 24, 2003 Hey Ramiro, Hasn't it been a month? Or are you busy and are waiting a little longer? Curious minds are itching. Garry Link to comment Share on other sites More sharing options...
