Is the result also behind PanF and D100? Is there any linkage between Tgrain films and results or woould the results be the same if HP5+ and FP4+ ewere used with TriX and Plus X? ( I am not trying to fingerprint films, but interested only in the data as Erwin plut is out to us..... and upon our own personal use habits....I prefer older film technology....) DD-X is a C41 type developer? IF so,,,, then.....Are the results at all affected by the use of basic C41 soup? vs maybe D76 or other traditional B+W developer? Excellent summary report......more reason to get the 21 ASPH... oh... please excuse that outburst.....I did not mean it, really Wife, I didn;t ..... Thanks again Erwin for keeping the data and the myths in separate camps. Frank Filippone red735i@earthlink.net Erwin said with some editing ........ Another myth went down. I used Ilford films PanF+, D100, D400 (to be replaced at Photokina by a newer emulsion called 400D!) and D3200. Also in the line was Kodak PlusX, At 12 times enlargement, the PanF, the D100 are in a class of their own, with the PanF having slightly finer grain. Here we see outstandingly good reproduction of details and tone values, the resolution of the system surpassing 100lp/mm on the negative. The often discussed three dimensional close-to-life- quality is very visible. At ISO400, the image quality drops significantly, but the sharpness impression is very high, but deceptively so. The life-like impression is gone and the image is flat. lacking depth and detail. But tonal quality is very good. At ISO1600 this impression is even stronger, no detail rendition, and again a flatter image, with good tonal range. It is evident, that the finer points of the quality of Leica lenses are mostly lost when using ISO speeds at 400 and over. The potential quality of the combo Leica and 100ISO BW will indeed intrude into H'blad territory. Erwin
