Compard and Foma provide tables^1,2 with development times for their R09 developers. Some of the times listed there seem to be inconsistent to the developer Agfa Rodinal (before 2004), which are all known to be the original Rodinal recipe. They differ in film speed for the same development times³.

FLIC FILM provides a datasheet for the film processing kit with the FLIC CLASSIC MQ developer. Some entries in this datasheet differ from the KODAK or ILFORD datasheets in the agitation scheme specified (e.g. for ILFORD films). These entries were corrected.

ARS-IMAGO pro­vi­des a tab­le¹ with de­ve­lop­ment times for its #9 de­ve­lo­per. Some of the times lis­ted there seem to be in­con­sis­tent to the de­ve­lo­per Agfa Rodinal, which are both known to be the ori­gi­nal Rodinal recipe. Showing the same de­ve­lop­ment times, it dif­fers at the agi­ta­tion rhythm² or at the film speed³.

Film Washi pro­vi­des a tab­le¹ with de­ve­lop­ment times for its Washi S film. The dilution for Rodinal lis­ted there seems to be a typo, because it is much to long. I looks more like the time for dilution 1+50.

Silberra pro­vi­des a tab­le¹ with de­ve­lop­ment times for its Ascorol de­ve­lo­per. Some of the times lis­ted there seem to be in­con­sis­tent: the de­ve­lop­ment time for the film Arista Edu Ultra 400, which is known to be the same as the Fomapan 400 and the Holga 400, dif­fers by one mi­nute.

Silberra pro­vi­des a tab­le¹ with de­ve­lop­ment times for its RDN-LQ de­ve­lo­per. Some of the times lis­ted there ap­pear to be in­con­sis­tent. This con­cerns the times for the equi­va­lent films:

• AgfaPhoto APX 400 (New 2013) and Kentmere 400,
• Arista EDU Ultra 100 and Fomapan Classic 100,
• Arista EDU Ultra 200 and Fomapan Creative 200 as well as
• Arista EDU Ultra 400 and Fomapan Action 400.

According to the data sheet¹ of SPUR Pho­to­che­mie, one should be able to in­fluence the con­trast of the ne­ga­tive by vary­ing the ad­jus­ted film speed, the di­lu­tion of the de­velo­per and the de­velop­ment time. This can current­ly not be map­ped by the app and would lead to in­con­sis­ten­cies in the es­tima­ted de­velop­ment times. There­fore, only the de­velop­ment times of the ta­ble were taken, which leads to a 'nor­mal' ne­ga­tive con­trast. The es­ti­mates of de­velop­ing time cal­cu­la­ted by the app for de­via­ting set­tings should there­fore also pro­duce a 'nor­mal' ne­ga­tive con­trast.

ADOX provides two datasheets for the film ADOX CMS II containing times for developing in Adotech III, one in German¹ and one in English². The two datasheets differ in the specified agitation scheme. While the German datasheet says: “Die erste halbe Minute ist die Dose permanent …, danach jede halbe Minute 1 mal …” (The first half minute ongoing …, than once every half minute …), the English translation shows: “First half minute ongoing than once every minute.”.

After contacting Mirko from ADOX, he wrote me that the agitation scheme of the English version of the datasheet (once per minute) is the correct one.

Kodak has launched new versions of some films on the market in 2002, 2003 and 2007. In many development charts, even in very well-known, these versions are not distinguished, although their developing times have changed. There are often listed as Plus-X , T-Max 100, 400, 3200 or Tri-X with mixed times for old and new versions of the films. You have to be very careful to find out the correct time. You are safe looking up the times at the Film Development Chart.

The development times of Uncle Mort’s Homebrew Neg Soup developer are substantially identical to those of the Champion Promicrol. The data sheet of Promicrol¹ and the times at the bottle label of Uncle Mort’s Homebrew² match exactly for 12 of the specified films. The indicated times of Promicrol apply partially for different film speeds (pushs) of the films. At the label of the Homebrew no film speeds are specified for the given developing times. The following table lists the identical development times of the two developers (dilution 1+9, temperature 20 °C/68 °F, agitation 30 s).

The two developers therefore appear to be very similar. The times of Promicrol originate from 2003: The times for the Kodak films therefore apply to the respective predecessor films.
The Promicrol developer allows 1+14 dilution. You can lookup the developing times for this dilution in the Film Development Chart.

The films Rollei RPX 100 and Rollei RPX 400 were respectively sold under the same name with different recipes. This is confirmed by the different developing times of different data sheets^1,2,3,4. In December 2013 these films were given a new packaging: Black background with green respectively red label. At the same time the films AgfaPhoto APX 100 and AgfaPhoto APX 400 were placed on the market. The development times of the Rollei RPX 100/400 films with old packaging were identical or at least very similar to those of AgfaPhoto APX 100/400 and Kentmere 100/400 .

Tetenal provides a datasheet¹ with developing times for its own Paranol S developer. Some of the times listed there are surprising: Tetenal stated that this developer is ‘compatible’ with AGFA Rodinal, but the developing times differ very much, especially for dilution 1+50. For our database we assume that these developers are not equivalent.

The development chart of Protopan 400 lists for the developer AGFA Studional (AGFA Studio Liquid) times at a dilution of 1+30. This is a rather atypical dilution for this developer and is considered to be a typo. Instead, it should probably be 1+31.
