- adj. Pertaining to photography which attempts to render truthful gradations in light and shade.
Landscapes taken on orthoskiagraphic plates are handsomer and much more correct than those taken on ordinary plates which let the green appear too dark and the blue horizon too indefinite.
This word is Greek in origin, coming from ‘orthos,’ straight, true, correct, regular, plus ‘skia,’ shade, shadow, plus ‘graphikos,’ of or for writing, belonging to drawing, picturesque.
