    It was a little crooked so I did what you do to straighten and it straightend just fine but left faint verticle lines throughout the entire photo.

    That's a software problem.  It's doing a mediocre job of calculating the rotated pixels.  It's possible that when exporting the image (to a JPEG, for example), the software might do more accurate (slower) calculations and the image would look as expected.  There's a lot of better software available these days, though.

    If the file were bad, there would be areas of noise, the file just wouldn't load at all, or the software would present an error message or maybe lock up.

    I still have good files on 5.25" floppy disks from the mid-1980s!  (Not recommending this, though.)

  2. Driffield wrote an article* that was published in 1903 (more than three decades before Photography Today) in which he describes exposing for the darker values and adjusting development to accommodate the lighter ones.  There aren't any catchy phrases in this article; nonetheless, a version of "expose for the shadows and develop for the high values" is expressed:

    • "[T]he deepest shadow of a correctly-exposed negative is necessarily represented by a certain deposit of silver."
    • "The development factor [...] for an interior requires to be less than that for an open landscape, in order to adapt their respective light-intensities to the range of the paper upon which the print is to be made."

    Adams quotes a line from this article in the front matter of The Print (1950):

    • "The photographer who combines scientific method with artistic skill is in the best possible position to produce good work."
