Dear Jan,
Thanks very much for the update.
As I said elsewhere, you are paying much closer attention to this than I.
Cheers,
R.
Dear Roger,
you are welcome.
One reason why I pay closer attention to these subjects is that I love using different films. Films of all manufacturers.
It is like a painter using different colors or changing his color pallete. I think I can make better photographs if I take the right film for the subject.
A fact I really like with film photography: I can always change my photographic sensor.
Examples: Spur Orthopan UR / Adox CMS 20, Agfa Copex Rapid / Spur DSX and Rollei ATP with ATP DC developer are all ultra-high resolution films with outstanding picture quality in combination with the dedicated Spur developers (these are by far the best developers for these films).
But each of this films has its own character, his own unique look.
ATP with extended red sensivity, looks like Kodak Tech Pan. Skin tones are very light, like porcellaine. With red filter you can cut excellent through haze in landscape photography.
Agfa Copex rapid is an orthopanchromic film, Skin gets darker, red is darker
Adox CMS is even a bit more in this direction, nearly orthochromatic.
Another great surprise of the recently new introduced Agfa-Gevaert films is Rollei Retro 80S (this is Agfa-Gevaert Aviphot Pan 80).
This film, although with classic cubic crystals, has significantly finer grain than T-Max 100, Delta 100, Pan F and Acros 100. I could not believe it at first, did several tests again and again then with different developers. Result was always the same, in all developers: It is the finest grain film in this speed class.
I got similar results to 4,5x6 when I used this film in 135. Incredible for a classic cubic crystal film.
Sharpness and resolution are on par with T-max and Delta 100, and better than Pan F+ and Acros (up to 150 Lp/mm with my Zeiss lenses).
And this film is absolutely flat after drying (in 135), no curl at all.
Because of its extended red sensivity you can do IR photography with special filters as well. Because of the extremely fine grain and high resolution you get a complete different look compared to HIE, SFX or the Efke IR films.
It is so nice to have alternatives. If I want grain, I take Tri-X or SFX, or the EFKE IR. If I don't, I take TMY-2, Delta 100, Retro 80S etc..
If I need excellent detail, I go for CMS 20, Copex Rapid or ATP.
You get the picture
😉.
Best regards,
Jan
