garden-variety 400-speed print film matches the 200-speed resolution of the

Also, for this kind of work, make sure you have a digital camera that can
save either raw (and convert later) or TIFF files. You don't want to go
through the JPEG compression if you can avoid it.
There is information on routine formats and resolutions on a page of the
primer on the CD-R side of my WWW site.
Briefly, one can reach 100 lpm on a very fine 35-mm camera system. That
yields 2400x3600x4~35 megapixels. With a zoom lens or typical user film,
the advantage over a 6-MP camera is slight. However, if output is to be to
a computer monitor or to a conventional printer (inkjet, laser or
equivalent), the available image quality from 2 MP is satisfactory.
Liner notes vary tremendously in resolution required for legibility. I have
some LPs where 600 dpi monochrome is barely suffiicent and others where 150
is ample.
