Re: Developing time 35mm vs. 120

Some manufactures publish different times for different formats. In some cases the emulsions are not identical or the film base may be different, but in general you can use the 35mm times as a starting point for most films regardless of whether there is separate data for 120 rolls.

Re: Moersch Chemicals

Jim,

We are hoping to add these products to our store in the near future, perhaps as early as next week. They are certainly capable of very good results, although their application is somewhat specialist, hence the cost.

Re: Neopan acros and F76+ times

I'd recommend starting with the time shown for 64 ISO. You can then adjust your time according to the results you prefer.

Re: Contrast vs. density: what is the difference?

Contrast is the amount of separation between dark and light tones, whereas density refers to the opacity of exposed silver in the negative. A dense negative is effectively a thicker negative which requires more exposure to enlarge, usually resulting in increased apparent grain. Overexposed or overde...

There was an error in the devchart, so the times for R3 were not available. I have fixed it now and you can see all the times by selecting "Rollei R3" from the film list at:

Hi Jim, I've checked the references on this and the data actually comes from the last ever chart produced by Acufine Inc. The actual times shown are: 35mm: 640 ISO, 6.5 mins, 21C/70F 120 roll: 640 ISO, 12 mins, 21C/70F More recently, Ilford has published these times for all formats (35mm, 120 roll, ...

dfbldwn,

We sell Ktol, which is an Xtol clone, in single packs. If you want the Kodak original Xtol, we can sell you single packs but the price is slightly higher than the case pricing. Please just contact us via the Digitaltruth web site and we'll be happy to help.

Rodinal has a compensating effect. At this dilution it is very contrasty and grainy, so I would recommend about 9-10 minutes.

You should not double the time as this will result in overdevelopment. Please select "Push Processing" from the text menu on the left column of the Massive Dev Chart to determine the best time. In general, you should add anything from zero to 50% more time depending on the exact exposure conditions....

The ISO setting is very misleading when using Infrared film. First of all, the film itself is sensitive to both the visible and the IR spectrum in proportions which differ from those which your light meter can interpret, so while you might find it useful to establish an ISO setting which will produc...

You need to guess an approximate time, so in this case I would consider adding about 15% to the development time for ISO 100. Maybe 11-12 minutes. There is no firm answer for push processing times unless you have tested in advance. You can use the Push Processing guide which can be accessed from the...
