Let's say you take the 35mm pic of the year and want to

enlarge it. Let's also assume you've used a slow b&w film. What is the maximum enlargement size before problems set in? Thanks.

The only way to tell is by actually having it enlarged, and seeing if it looks good. I've enlarged Tmax 100 (shot on a tripod) to 16x20, and it still looked pretty good, and I'm picky.

It really depends on what you feel is unacceptable.

You can enlarge it to gigantic proportions if you are so inclined...it will look fine if viewed from a sufficient distance.

It also depends on things like lens quality, whether a tripod was used, etc.
