There's no more visual information to obtain; when the photo was reduced to a halftone, the actual visual information was mostly destroyed, doesn't matter what resolution you scan it at-- the information isn't there.

If you can obtain an original negative or slide from the photographer -- that can be scanned at much higher resolution. There are some medium formats negatives from Nancy Suiter photo sessions that are sold on EBay, for example . . . this _is_ worth a big scan (I bought two and am working on scans)

But a poorly printed old magazine shot really is fully represented in a 250 kb jpeg; 1 meg is overkill for anything but very high quality printing (say a Playboy centerfold).

Its like you'll see some VHS tapes that have been ripped and produce giant files -- they can be greatly compressed with no loss, because there just isn't that much visual information there.

I'd like to thank everyone who has contributed to this post and opened my eyes to the issue we all face, not having a better quality picture to scan than that of the magazines we all know and love.


You have truly opened my eyes to the limitations of scanning these magazines and it saddens me that we will never have the opportunity to have better scans for a lot of this content.

Original slides and negatives _do_ come on the market. Check Ebay, there are auctions all the time; every Vintage erotic enthusiast will appreciate a good quality scan of some original film.

To be honest, I've invested a small fortune in my collection already and am in the process of transferring everything to digital format, whether pictures, VHS or DVDs. Once that is done, I've either shredded to magazines, cut up the VHS tapes and shattered the DVDs. And yes, I could sell it, but that is another step I just don't have the time for.


It's just more time I do not have, to be constantly scouring ebay for items. So I will leave it up to some other enterprising youth to look for those items on ebay and hopefully scan them for everyone's enjoyment.

As you rip VHS, the same advice applies-- there's maximum size beyond which additional data gets you nothing. The mathematical theory behind this comes from the famous mathematician/engineer Claude Shannon . . . but suffice to say if you're ripping VHS to 4 gigabyte files, that's probably about 3.2 gigabytes too many.

Depends which compression tool you use, but most will automatically recognize that amount of data and compress efficiently -- handbrake does a particularly good job of this in my experience.

One piece of advice with VHS ripping-- if you can find a "pro" deck with time base correction (or an external time base correction module, something like AV Toolbox AVT-8710) -- that will significantly improve your rips. Older tapes will have stretched a bit, and that puts them slightly out of sync, yielding characteristic noise and distortion on old VHS tapes.

Time Base Correction can fix these errors, which are particularly bad with NTSC. But the consumer decks don’t do it, and this is a big contributor to poor quality in VHS rips which _can_ be fixed, with the right equipment and settings at the time you do the scan.
