Developer for Aviphot Pan 200

[destroya]

It is the formula I was experimenting on in this thread, but if you are new to this it may not suit.

Developer for Aviphot Pan 200

The guy who posts on Youtube as "the naked photographer" presented D-log E curves for Rollei Superpan 200, Rollei RPX 25 and Agfa Copex rapid [among others he is in process of presenting]. If the liberty is taken of assuming these are Aviphot 200, Aviphot 80 and Agfa Copex rapid and they are...

I modified the times to 8m +8m 20C as mentioned in post 237.
At the moment I am working on a single bath version, not finished yet.

What Alan posted.

 

[destroya]

just wanted to post 2 quick scans from RR80s 35mm using MeCD4 that I took on my hike before going to work, which you can see in the 2nd photo, Lick observatory on the top of the hill. the first is an IR shot.

I have found that the MeCD4 gives a lower contrast neg but is grainy, but also sharp. I need to wet print one whenever I get around to setting up my enlarger again. Alan, have you found your results sharp but slightly grainy? just wondering.

I agree, the grain is about the same as my efforts with Rollei Retro 80s:



I got a bit lazy and lately moved on to a single bath developer which have been using with CMS 20 and Spur Ultra R 800 microfilm types:

CD4-LC low contrast developer for scanning

I have found that use of high concentrations of CD-4 reduces the contrast of microfilms [pic] and the contrast is further reduced by minimal agitation every 3 min. In combination with reduction of contrast in scanner software this enables some microfilms to be shot at box speed. The CD-4...

Have not tried this with any of the high contrast films Aviphot, Ferrania P30 or Ilford Ortho yet.

@Alan: Two short questions. Is pre-wash for MeCD-4 development recommended? And the second one about the water temperature for mixing the chemicals of part A and B? Thanks

 

[Alan Johnson]

I put the formula again since it is way back now. 5min 25C or 8m 20C usually gives better results than the shorter time initially tried.

MeCD4 two bath low contrast developer:
Bath A
Metol...............................1g
Sodium Sulfite anh..........35g
Color developer CD-4......4g
Sodium Metabisulfite........1g
Water to............................1L

Bath B
Sodium Sulfite anh............35g
Sodium Carbonate anh......30g
Water to..............................1L

Develop 5m +5m 25C, correct the time for other temperatures, I use the Ilfordphoto chart.
Agitate in Bath A 2 inversions every 30s
Agitate in Bath B 2 inversions at start and 2 inversions at half time only.

MeCD4 flattens the S curve of the Aviphot films to some extent giving EI=200 for Aviphot 200 and EI=80 for Aviphot 80.
CD-4 appears generally the least likely of the CD series but it may cause an allergic reaction in some individuals.

No pre wash is needed before bath A as it is mainly the intention that it should be absorbed in the emulsion rather than do any developing.
With the usual pinch of sulfite before adding the metol, all ingredients dissolve quite easily in demin water at 40C.
For a single bath version see CD4-LC mentioned in post 253.

Thank you Alan!

Has anyone tested a similar formula based on CD3?

 

[Marcelo Paniagua]

I've always developed Aviphot (40 and 200) using POTA developer. Although you loss one speed step, it gives pleasant contrast. Also, had pretty good result with F76+. Although I got more contrast than POTA, got better speed and contrast wasnt over the top. Used Aviphot 200 @200 with F76+ (68F for 14 min). For POTA, use it at 75F for 14min. Used one inversion agitation each minute.

Not as far as I know. @Alan Johnson has been the one working with and experimenting on improving contrast behavior using color developing agents. His public formula is posted above.

Somewhere in the 11 pages I have yet to get through.

I have a load of Xtol and a load of Aviphot that I have to develop. Anyone here messed with Xtol/Aviphot combo? I want to use replenished Xtol. Been shooting the stuff at ISO 100. Google isn't giving me any times for the stuff.

Agfa Aviphot Pan 200 is sold for aerial photography and for this purpose gives a high contrast as the land photographed has relatively low contrast. I believe it is sold in 35mm eg as Rollei Retro 400s.The resolution is up to 181 lppm.
For aerial photography it is developed in Agfa G74c plus G74s, from the msds I concluded that this combination is a high pH PQ developer. I was curious to see from the diagram on p8 of the link that developing for long times in this combination gives a notable increase in shadow speed. However, the corresponding curve , for 20 min, would likely give blown highlights when the film is used for pictorial photography.
My question is, what developer might give the notable increase in shadow speed but make the curve less steep thereby giving good results for pictorial photography. There is a lot of data on the massive development chart but some complain of high contrast.

As a side note, the question should be: "why am I using an aerial film for pictorial pourposes?"...

I'm joking...

Maybe the only good option for near-IR film

For true IR film there's Ilford Sfx 200...

Assuming you refer to Aviphot 200 shot at EI=100, maybe somewhat reduce the time from that suggested for Rollei Retro 400s at EI 200 as a starting time:

This is not true infrared film. If I have to compare it with Aviphot 200 - I prefer the second one. I get better results.

Because it costs me less than .10 a roll. Because I can roll it into any format I want. Because it's near IR. Because I have it.

Guess I'll have to do the 'ol try it out and figure out a time. Not a problem, I had to figure out D-76 on my own. If anyone is wondering I found 18 min at 1:1 gets good results.

 

[Marcelo Paniagua]

My thoughts exactly. Also, I get different results modifying the developer/developing time so fun to use.

I've had 'good enough' results with it. Basically it's film that I use for testing and walk around. I'm not doing my thesis using this film.

Last camera I used it in was a Ricohflex VII with cardboard baffles in it modified to shoot 6x3 images. I'm not using a roll of Tmax for that.

I agree. I mean, pictures come ok, not gallery Quality but, like you said, good enough, suitable for my daily use, pictures from My cats and explore the potential of my less used lens.

Exactly. I got into photography because of TLRs and I like using them. If the photos come out swell then I'm not going to complain. If they come out awful I'll say I planned it like that and it's my 'look' yeah? Embrace the mottling and grain.

Loads of folks repackage Aviphot, including where I get bulk film now, Astrum.

The reason I asked is because I don't understand why one choose an aerial film for pictorial pourposes while pictorial films are still available...
Maybe I can understand if you use Aviphot for reversal, but as a negative no...

A lot of those cheap B&W films are Aviphot. CatLabs 80/320, JCH Streetpan 400, Rollei 80s/200/400/IR, etc. Why do they use it? Because you can get it in master roll quantities for cheap.

Can you please tell me where to get them in master roll quantities for cheap?

If you want 47 rolls of 35mm, or 27 rolls of 61.5mm film 540m in length, Agfa. They have a contact form here.

(If you were wondering, you can also buy Kodak Aerocolor in large quantities as well, 38 rolls of 35mm, or 21 rolls of 61.5mm film, 300m in length.
