Television is only 72PPi, pixels per square inch, not Dpi, dots per square inch, (thats print). 2700 per inch huh? Thats a lot more than you need, and more than they could push from your small film. Killer new film that pros use, (real film, not hd or video) can maybe be 3000×3000 (I think, somebody check that for me) so asking them to give you such a high res transfer. 6cm film negatives should produce res that you can use for pan and scan and zoom. At least 150 dpi (print speak) ppi
should be enough. And they wont say those things about you anymore.
