Source is Liverpool Flora . See details @ very bottom of page. - I think this pic is probably best viewed as to be used in an intermediate process rather than as presented, though could be. Let me explain my thinking... - Original book pages are unevenly foxed (yellowed) and stained so have been desaturated, and the levels pushed to get a semblance of lightness, but patina/texture of paper pulp grains are just visible in off-white areas, and there may be faintest traces of print-through. However, the ugliest of stains & foxing are removed, but stray ink dots may exist. This provides 3 user options: - (1) Use image with a yellow-orange tint to make a more controlled 'faux' old page, using levels to introduce more of behind the scenes print-through if desired. (Option 2) Flood fill outer area with 100% white, but keep pulp patina in leaf/flower area to give separation from pure white outer area. (Option 3) Turn into a full 2-colour HC B&W stencil-like image tweaking white/black threshold levels. - Line illustration sourced from 'The Flora of the Liverpool District' - Edited by Conrad Theodore Green [1863-1940] and illustrated by Emily Margaret Wood [1865-1907], so believed to be out of copyright.
