I wonder how this new film compares with the ADOX CMS 20
|
CMS20/SPUR Orthopan UR is orthochromatic
MICRO-film.
ATP-V1.1 is not a micro film and has extended
RED sensitivity (like the Kodak Tech Pan film)
So huge differences.
Depending for what you want, both films are very interesting. But micro films are very slow. A Tech Pan film can be pushed more easily to iso 40 without too much damage from the steep log D curve.
However when using ATP with Rodinal 1+150 or any document developer (also low contrast) the iso rate is limited till about iso 20-25 in pictographical use.
Mr. Erwin Puts will publish soon some direct rsults of these films, including their log D curves.
Both films are very interested in usage with some better lenses like those from Leica, Zeiss, Rollei, Hasselblad (also Zeiss) a.s.o.
