One of my pet peeves is the practice of posting a link as a basis for forum discussion. It seems like an invitation for people to ignore the linked content and just jump in with their opinion. Well, here I am posting a link to an online article that I found interesting and worth wading through all the technical stuff.
Exploring the Limits of 35mm BW Photography
The article was published in response to marketing claims related to Gigabit brand film and contains a fair amount of technical explanation and research in regards to real world resolution and performance of currently available lenses and films. What I gleaned was:
- The resolution of most systems is limited by lens quality, not film grain
- Even with the best lenses, the system resolution is such that about 20x is the limit for reproduction magnification (19" x 28" enlargement from 35mm)
- It is difficult to attain greater than 100 lp/mm resolution at the negative
- TMax 100 was judged as the real world equivalent to much slower ultra-fine grain emulsions (at least for resolution). One could assume that the same would apply to Acros 100 or Delta 100.
For balance, here is a second post where the same author gushes about Adox CMS 20:
