The standard dilution for Fomadon LQN is 1+10. The chart has been amended to show the correct dilution.

Pan F+ has been around for a long time, so if you still have a box of Pan F then it will have lost film speed if it has not been frozen. As a result, it is hard to say what a good development time will be. The development time differences between the old Pan F and the newer Pan F+ are not wildly dif...

I'm a bit confused about what you are asking, but 2:7 is the wrong answer. What you are doing is diluting a dilution. The first dilution is 25% (1 part developer + 3 parts water). The second dilution is 20% of the first dilution (1 part stock solution + 4 parts water). My math isn't perfect and mayb...

When Germany was divided into East and West at the end of WWII, production of many Agfa products continued on both sides of the wall. While the Agfa brand continued in the West, in the East these products were produced in the old factory under different names, hence Atomal and A49 being equivalent. ...

Topic: Double Exposure

Views: 9025

There is no simple answer to this question. To make a double exposure you need to expose a piece of film to two separate scenes. How you do this depends upon your equipment and which film format you are using. If you are using 35mm, then your camera may have a double-exposure button. If it doesn't t...

Have a look at the Push Processing chart which is listed in the left hand menu of the Massive Dev Chart The chart indicates that you should develop your TMax film by a factor of 1.66 to push it from 400 to 3200 (3 stops). If you use the 5 minute time for Rodinal 1+25, that makes a new time of just u...

If you multiply a time by 1.4, you are adding 40% to the development time. This is not too dissimilar from adding 50% per stop. In general, these type of calculations are excessive and designed to rescue film which has been incorrectly exposed. If you are pushing film to gain more speed, either for ...

R09 is the original formula for Rodinal. It is still produced today by Calbe. Rodinal has outstanding keeping properties, and there are stories of people using 40 year old bottles of Rodinal and still getting results. If the developer has oxidized you are out of luck, but why not try it on a roll an...

The old times will work well as starting points for this combination, and any difference should be marginal. Other users report times ranging from 17-22 minutes for the 1+3 dilution.

Please submit your time to the chart if you get good results.

As it states in the chart, you should use the old times as your starting points. Although some users report different times, in general I think this can be put down to differences in processing techniques or the use of erroneous data which had never been revised. Dick Dickerson and Silvia Zawsdzki p...

I'd recommend a starting point of 14-15 minutes at 1+3 for Tri-X. Let us know how it works out.

You can extrapolate a starting point by looking at the times listed for other films. In this case I would guesstimate a starting point of around 10-12 minutes.

If the film has not been frozen during this time, then the likely speed loss is quite significant. I would double the suggested times and hope for the best.

Its hard to say what the cause of this problem is without being able to see the negatives. A high wash temperature could cause reticulation which might be what you are describing, but it would have to be near boiling and even then I doubt this is the cause. I would suggest trying to rewash a single ...
