Lens recommendation for dia film reproduction?

My plan is to make RAW files of may old dia pictures .... forgot to mention, you won't be able to make "RAW" as that usually implies in digital photography, but definitely TIFF which will carry the full depth of colour for each scanner pixel location in CYMK (or other colour schemes if you prefer), but not RGB bayer with the raw values for each pixel. tl, dr version: TIFF is a fine format. -- "...there are many humorous things in this world; among them the white man's notion that he is less savage than the other savages." -Samuel Clemens |

When the whole approach that was being considered is so completely, utterly and totally mistaken, there's very little point in refining each part of the "chain of mistakes" Use a film/slide/dia scanner. Or just don't bother. |

Or just don't bother. Having gone down that road, I'm going to disagree: The touch labor involved in "doing it right" with a proper scanner means that in most instances, it becomes a "don't bother" project. As such, my advice is: Step 1: Use whatever "lousy" capture process you can that's fast & easy so that at least a copy - no matter how crappy - actually gets accomplished. Step 2: Use this output to cherrypick what images are actually worth the effort of a high quality scan Step 3: Do (or pay for) the high quality scans on the cherrypicked subset Overall, this is the "Better is the Enemy of Good Enough" paradigm put into practice. -hh |

Step 2: Use this output to cherrypick what images are actually worth the effort of a high quality scan Step 3: Do (or pay for) the high quality scans on the cherrypicked subset Scanning film-based images is unavoidably going to involve doing a lot of work. Best done methodically and systematically. Given that, my experience doing exactly this is that if you're going to have to do a lot of work, it makes sense to only do it the once. Garbage-In, Garbage-Out, then do it right like you should have done it in the first place isn't it for me. What use is a "crappy copy" to man or beast? Or even hundreds -- thousands -- of "crappy copies"? Obviously, there has to be selection -- judgment -- about which images are worth scanning, and which one's aren't. (Or, often which images are worth scanning in order to keep a good/important part of an otherwise faulty or lousy total image). However, in my experience, that kind of judgment is best done during the scanning process (given that the scanning process will generally include an initial pre-scan before the scan proper). It's at that point when one decides whether to go ahead with an image or to skip it. Doing twenty years' worth of pre-scans in the hope of then selecting which ones to go back to again in order to do properly is both inefficient and soul-destroying. You need to take a decision while your engagement with the particular image is fresh, not months down the road. |
