message: Is this image Bayard's? Dated circa 1840. Seems fishy to me, definitely interesting if it was really one of his works. OrganicEarth (talk) 00:51, 30 July 2015 (UTC)

message: The description of the process differs from that given in Historic Camera, which follows:
The process itself was relatively straightforward. First, the paper was treated with sodium chloride. After drying, the paper was submerged in silver nitrate to create silver chloride, which is sensitive to light. The paper was then exposed to light until it turned black, washed, dried, and then stored in a portfolio until needed. Before the paper could be used, it had to be saturated in potassium iodide, placed into the camera, and then received light exposure. After being treated in sodium thiosulfate and placed in a bath of ammonia and water, a positive photographic image would appear on the paper.

message: While working as a civil servant, Bayard experimented with photography.  He developed his own method of producing photos called the direct positive process.Hippolyte Bayard
Direct positives in the camera are produced by a number of processes eg the daguerreotype, tintype, Kodachrome and other transparency films. Direct positive paper prints too - the Metropolitain museum will classify direct positive prints in the camera as direct positives as a class of images. Bayard did not call his process by any particular name, as there was no commercial activity involved in selling and marketing it. There is direct positive paper marketed by Ilford today for using in large cameras without the expense of film. RPSM (talk) 12:58, 21 July 2017 (UTC)

message: Can we have a better version of the photo of Chevalier?  Surely Bayard did not cut out the original and paste it on a Photoshop gradient.  Here we're trying to represent an artist's work authentically.  President Lethe (talk) 21:24, 25 July 2021 (UTC)
