Highest res 400 iso film?

[johncox]

<p>Whats the highest resolustion 400 iso Black and white film? Needs to be a true Black and White and not a c-41 film like xp-2. Am I right to assume its TMAX 400?</p>

[larrydressler]

<p>Rollei 400S or TMY-2 Also known as TMAX 400.</p>

[JDMvW]

<p>Just curious, why not the C-41 films?</p>

[john_shriver]

<p>Much sharpness is lost in color films as the light diffuses through the many layers of emulsion.</p>

<p>Because I need to able to develop it at home.</p>

[glen_h]

<p>I am pretty sure that the C41 B&W films only have one layer of emulsion. <br>

Like color films, though, the image is dye clouds and not silver. This reduces "grain" as the clouds have softer edges. <br>

I am not sure how to describe it in resolution terms. <br>

You could scan at high resolution, then run a non-linear deconvolution algorithm on it.</p>

Ditto, T-Max 400. Delta 400 is pretty good too,

although I preferred TMY.

 

 

Results will vary somewhat with developer. I like

Ilford Microphen, which offered a good compromise

between speed, acutance, contrast and reasonably

fine grain. Some folks prefer other acutance

developers - Beutler types, or Rodinal. I found

Rodinal grain a bit too pronounced for my taste

with T-Max 400, but it's a good look for some

styles.

 

Several years ago there was a fairly extensive

and detailed thread on this forum with

recommendations. It's around 2001 when Bob

Atkins was asking about replacements for a

discontinued film for testing lenses. Check the

replies from Wilhelm and a few other folks who

were active back then.

Ugh, darned photo.net stuttering servers.

[larrydressler]

<p>Lex if it happens to you then I know when it happens to me it is not my fault. :D</p>

[lex_jenkins]

<p><a href="/black-and-white-photo-film-processing-forum/002Z9E"><strong>Here's the 2001 thread</strong></a> I was trying to remember. I think the "Wilhelm" in that old thread was Bill Mitchell, not Henry Wilhelm of Wilhelm Imaging Research.</p>

<p>And <a href="http://cacreeks.com/films.htm#filmscan"><strong>here's a web page</strong></a> with a compilation of various RMS and lp/mm charts, with some brief background info. Probably a good idea to double check the sources, but at a glance those charts appear to be about right.</p>

<p>And C-41 process monochrome films do compare favorably in resolution and RMS to ISO 400 silver halide films like T-Max 400, Tri-X, etc.</p>

[User_1577653]

<p>There is a thread on APUG in which PhotoKlassik magazine's Henning Serger reports measurements made for resolution, grain, and other factors for a multitude of different films. On <a href="http://www.apug.org/forums/forum37/131396-rollei-rpx-25-grain-resolution-5.html">this page</a> he lists results for 400 speed films. You will have to look earlier in the thread to get an explanation of their test methods, but the bottom line is that it looks like T-Max 400 was measured as the highest resolving among true B&W films. </p>

[larrydressler]

<p>There are also factors like Developer used and so on... I know Kodak used to use D-76 as the baseline for test of that nature.</p>

[DB_Gallery]

TMY2 is an outright masterpiece, my favorite black and white film. I use it in 35mm, 120 and 4x5. With lenses from Leica,

Mamiya, Hasselblad or modern LF plasmats like the Apo Sironar series, it's screaming sharp. I develop it in Xtol 1+1.

[larrydressler]

<p>Maybe Ron or someone else that was with Kodak can tell. I heard that Kodak changed to TMAX developer or XTOL for doing baseline testing.</p>

[dave_wilson1]

TMAX and Microphen is a top choice for the Hasselblad. I really like the Delta too, but am about five years without a dark

room at this point.

[Fotohuis RoVo]

<p>Kodak TMY-2 and Rollei Retro 400(S). Last one is an Agfa Aviation type film, Aviphot 200 E1 so in fact an iso 200 film where Kodak is a real iso 400 film with the latest Tmax 400.</p>

[larrydressler]

<p>The Rollei 200 and 400S are also high contrast to cut through haze and work better with filtration but both are sharp as a tack but don't try to push them.</p>

[Fotohuis RoVo]

Rollei (S)uperpan 200 and Rollei Retro 400(S) are exactly the same Aviphot 200 E1 emulsions from Agfa Gevaert. In

most developers iso 160-200. E1 means 100um used both for 35mm and 120 roll film format and (S) stands for

(S)ynthetic clear Polyester layer. Another version is the Retro 80(S), Aviphot 80 E1. What is in the RPX-25 is not really

clear even to me. But it is also thin clear Polyester layer and Gevaert is also making an Aviphot 40 E1 type emulsion.

Another posibility is OrWo Filmotec who has also made the new Ortho 25 film for Rollei-Maco. In principle they have the

recept of OrWo NP15, which they did already for the Rollei PAN 25 version 1 in 2006. Later Efke / Fotokemika made a

best quality Efke 25 for Rollei Pan 25 2nd version, up from 2008 or so. But all OEM films stopped in August 2012 when

Fotokemika in Croatia ceased all production.

[Fotohuis RoVo]

In general use for all Aviation type films a lower contrast working developer. Or a semi-compensating type developer. Best

results I got with AM74 1+15 or Rollei High Speed (OEM from Amaloco), the new Rollei Supergrain (made by SPUR an

AM74 copy 1+15), A-49 1+1 (Calbe/Adox) or LP Doku LC / Film Low Gamma / Rollei Low Contrast (Udo Raffay, Labor

Partner 1+4 or 1+5), TDLC-103 1+0 (a modified Beutler where Soda is replaced by Sodiumbicarbonate) or Caffenol (well

you have different versions to make).
