T Max processing
I usually don't use T Max but that was all I could get this week at the
local camera store (they DO stock film but are moving soon and have a reduced stock at the moment). Do I have to use T Max developer or can I use the old faithful D76. Or is there something else better for T Max? -- Michael |

T max is a very exposure critical film subject to blown highlights. D76 or HC110 can certainly be used but a nice dilute developer rather than the 1to1 and B dilutions, may serve your purposes better. If you meter carefully and match the developer concentration to your intentions and use filters to regulate the high end of the exposure, you can get full emulsion speed from the Tmax films. -- Reality is a picture perfected and never looking back. |

I find TMax requires longer fixing times than other films. YMMV. Laura Halliday VE7LDH "Non sequitur. Your ACKS are Grid: CN89mg uncoordinated."

I use D-76 diluted 1:1 for most T-Max except where I want the finest possible grain on 35mm and for that use either Microdol-X or Ilford Perceptol (they are identical). T-Max films are somewhat more critical of development than conventional films. A difference of 20% in time will result in about a one paper grade difference in contrast where it takes about a 30% variation for conventional films. So, be careful of temperature, agitation, and time. Despite some bad press T-Max is capable of excellent tone rendition and is quite fine grain compared to most other films of similar speed. Despite the warning in another reply it is not more critical of exposure than other films, I think that person is confusing exposure with development, which _is_ more critical. To insure good shadow detail in any film rated by the ISO method expose it at about 80% of the box speed. Kodak has very complete data sheets for all three T-Max films on its web site. I strongly suggest reading these over to get best results. T-Max developer is a modern liquid concentrate developer (actually two versions) using the T-Max trade name but not having any other connection to the film. T-Max and T-Max RS are excellent pushing developers but are somewhat coarser grained than D-76. Xtol will deliver about the same speed as T-Max RS but with finer grain than even D-76. The only problem with Xtol is that some users have experienced a sudden failure of the developer after it has aged for a few days to a few weeks. If you use Xtol check it each time with a scrap of film to see if its working properly before using it. No one is sure what causes this problem although there have been a number of theories from reasonably knowledgible people. D-76 remains after some eighty years the standard of comparison and will give good results with nearly any film. -- --- Richard Knoppow Los Angeles, CA, USA |
