Original – From the article: "The idea of using several exposures to fix a too-extreme range of luminance was pioneered as early as the 1850s by Gustave Le Gray to render seascapes showing both the sky and the sea. Such rendering was impossible at the time using standard methods, the luminosity range being too extreme. Le Gray used one negative for the sky, and another one with a longer exposure for the sea, and combined the two into one picture in positive"

Reason: High quality scan of a 160-year-old example of a popular technique

Support. Nice to see the HDR article include historical examples and techniques. Perhaps I'm mistaken but I don't recall seeing them last time I viewed the article. I do think that perhaps it deserves a slightly better modern tone mapping example too. The one provided is fine, but the overall image quality and tone mapping is not as good as it could be IMO. Perhaps that's one for me to work on! Ðiliff «» (Talk) 00:04, 24 August 2015 (UTC)[reply]
- You are one of our better HDRers. I'd include a version with original frames as well, to make it more encyclopedic. Like here — Chris Woodrich (talk) 01:02, 24 August 2015 (UTC)[reply]
Support, interesting, didn't even know it existed back then. Brandmeister^talk 09:06, 24 August 2015 (UTC)[reply]
- It didn't exist back then in the same way it exists now. The photo was simply two seprate exposures superimposed in a fairly crude way - the horizon was the dividing line. There was no tone mapping or any complex blending. That still makes it HDR in the sense that it creates an image with greater dynamic range than is normally possible, of course, but not as we know it now. It's more analogous to a graduated Neutral density filter in the way it creates the final image, but it uses two exposures combined into one during the deveopment process, instead of a filter.

Support – Wow, that took some doing in 1856! Good EV for history of photography – and BTW a neat comp. Sca (talk) 13:44, 24 August 2015 (UTC)[reply]
- It might not have actually been as difficult or complex as you might think. When you're developing a negative using an englarger, it's theoretically trivial to just block the part of the projection that you don't want to expose on the paper. Ðiliff «» (Talk) 23:54, 24 August 2015 (UTC)[reply]

Now you mention it, I remember the ol' fotogs doing that in the newspaper dark room. Sca (talk) 21:36, 25 August 2015 (UTC)[reply]

That's where the Photoshop terms 'dodging' and 'burning' come from - the physical interventions in the enlarger during the photographic development. This video is a good demonstration. Ðiliff «» (Talk) 22:36, 25 August 2015 (UTC)[reply]

Yup, I remember them sorta waving their hands in the light of the enlarger. If results weren't up to snuff, they could always do it over. (Those were the days of Tri-X, the all-purpose B&W film – used by newspapers for decades.) Sca (talk) 14:19, 26 August 2015 (UTC)[reply]

Support Gustave Le Gray also invented the selfie and photobombing, but I don't think any examples of these survive. Belle (talk) 08:36, 25 August 2015 (UTC)[reply]
- I bet Leonardo da Vinci would have invented Photoshop in the 1850s, since he envisioned parachute already in the 16th century to say the least. Brandmeister^talk 09:55, 25 August 2015 (UTC)[reply]
