: For slide film, I don't know if it develops directly into positives or if there's another step involved where they basically make a negative of the negative and stick it into a slide case. I never developed slides at home when I was playing with developing my own film back in the 70's. One of the slide films, Ektachrome?, develops as a positive; it's a complex process because the dyes are in three layers. WYSIWYG. --Damon |

That doesn't hold true when you submit a request for a few photos from the middle of a 100-foot-long reel of positive film. In that case, negatives must be developed and handled separately. This process is not inexpensive. snip Whether NASA returned the original film as negatives or kept the original negatives and returned copies or something that had been produced by manipulating the originals is a separate issue and one that I know nothing about, not being involved in the aerospace industry. It's my understanding that NASA returned copied negatives, not originals. Whether said copies had been creatively altered from the originals is to some extent TBD. Challenger's Ghost |
