My very first foray into AZO resulted in the 4x5 contact prints which I sent out on the last group print exchange. I was quite pleased with the prints themselves, but having rec'd three stunningly beautiful prints to compare to, I have learned now that my mounting and matting is absolutely atrociously poor and inadequate - I'll learn from this. I have since purchased an 8x10 Agfa Commercial View and some PlusX Aero, so recently I headed out to "try it out". I took two pictures on my first 8x10 outing and when I got home, I developed them in trays in divided D23, which is the developer I have been using for everything (except for the odd episode with Rodinal - just so I don;t get expelled from the congregation ) I took the first two 8x10 negs and contact printed them on GR3 AZO and got these results. 1) The first attempt was a bit dark : http://www3.sympatico.ca/oldrad/Photo/LargeFormat/Prints/AZO/Kilmaurs001.jpg So I redid it a bit lighter: http://www3.sympatico.ca/oldrad/Photo/LargeFormat/Prints/AZO/Kilmaurs002.jpg The second negative I also contact printed on the same AZO and got: http://www3.sympatico.ca/oldrad/Photo/LargeFormat/Prints/AZO/Diamond001.jpg I know I have a dust problem with these and have since taken steps to correct this - there's a heck of a pile of square inches of static electricity in an 8x10! I also found that AZO really like FRESH developer - this stuff was getting to be like a fine whiskey - OLD!! and I remembered after I did these that when I did the 4x5's, I had to use super fresh developer to get non-grainy clean whites. Anyway, so far so good - I'm learning as I go. I did the "next" two negative differently. I "anti-dusted" before cutting and loading the holders and I also made an ABS tube to develop in. The third and fourth negs turned out MUCH nicer. I extended the development time a bit to darken them up as the first two were very thin. I also agitated continuously in the tube and the negatives are absolutely even across the face whereas the first two weren't. I don't have them printed yet, but I'm looking forward to seeing the difference that trays/light agitation vs. tubes/constant agitation makes in the prints.
