Hi,
So far I have simulated orthochromatic film by using bluish-green filter and I have found that very useful in many situations.
Now it's time to look for and test some film, but what? As I have searched, my foundigs are (for 4x5):
- Efke PL 25M
- Rollei Ortho 25 (same as Adox Ortho 25)
So only ISO 25... Anything faster?
Should I also think Adox CHS 50 Art, which is Orthopanchromatic film? It's response drops above 600nm and ends around 630nm.
