User:MIckStephenson/Preservation of historical images

From Wikipedia, the free encyclopedia

This discussion is being started with the goal of establishing a consensus among project members regarding what kind and amount of retouching of historical images such as the example should occur for images to be used in articles here on the English Wikipedia.

Example from Sswonk (talk):

I recently reverted[3] the placement of the right hand image, or "JQA2", above in the article John Quincy Adams. While I appreciate the effort, I disagree with the intentions and results of the editors who did this. The left side image, or "JQA1" was so significantly altered as to destroy any historical context it possesses. JQA1 was originally also retouched from the Library of Congress (LOC) as can be seen on the Commons description page. The LOC image is directly linked below.

You realise, of course, that the vast majority of historic images are not photographs, but include engravings, lithographs, paintings, and other such works. Shoemaker's Holiday Over 205 FCs served 00:11, 14 September 2009 (UTC)
Actually the vast majority of historic images are not glass plate rephotography of daguerrotypes. Hard cases make bad law, as they say. Durova318 00:45, 14 September 2009 (UTC)
The discussion here will hopefully lead us to a benchmark for all historic images. The Adams image just happens to be a photograph, one with an interesting precedence in terms of reproduction that should serve us well as one example, with others added as & when. It's a complex issue and rather than start it as it appears here I'm planning to reference and summarise the original discussion that sparked it off, along with links to related discussions, explanatory notes etc which will (hopefully) save loads of confusion and tangental arguments. --mikaultalk 02:18, 14 September 2009 (UTC)
You do realise there's a fundamental difference between an engraving, and, say, a painting or daugerrotype that would make rules appropriate to the latter appallingly stupid for the former: There is no such thing as "historic damage" in a mass-produced work, since engravings, lithographs, and the like were meant to be printed hundreds or thousands of times. Any damage on such a work cannot be considered "historic". Shoemaker's Holiday Over 205 FCs served 02:51, 14 September 2009 (UTC)
I do realise you didn't read the discussion I linked to, where I pontificate in tiresome detail as to the likely veracity of digital copies we have here compared to their analogue originals. The distinction you're making there is relevant only to verifiability. The sort of rules that apply to this project relate to digital reformatting, almost irrespective of original media types, in which case all of our scanned images can be assessed from a common perspective. Within this there are likely to be a variety of standards, depending largely on the type and quality of calibration, but the only fundamental differences are those between born-digital images and scanned analogue images. The argument is that image editing of the former requires a slightly different set of ethical guidelines to editing of the latter. The objective here is to establish if that is the case and, if so, what those guidelines should be. --mikaultalk 07:22, 14 September 2009 (UTC)
