    The comment at 1:11 that Talbot was a member of the House of Lords is incorrect. Talbot was an MP in the House of Commons, but never sat in the House of Lords, as he never held a peerage title. He was a grandson of the second Earl of Ilchester through his mother, but was not himself a Peer of the realm.

    When Arago, on January 7th, made known Daguerre’s invention, Daguerre received a pension from the French Government on the understanding that he was donating his discovery to the world. Shortly afterward he patented the Daguerreotype in England through Miles Berry an English patent agent. This put Talbot in an impossible situation leaving him with no option other than to take out a patent to protect himself and his calotype negative-positive process. Through Berry Daguerre registered several additional addenda with the intention to obfuscate the differences between images made on silver-coated copper and images made on paper. Even to the point of describing his process as being a photogenic process. Old myths still persist, hence “Talbot’s greed”; check the facts! The fact that French nationalistic PR was so successful that it led to Talbot’s calotype negative-positive process being referred to as “Daguerreotypes on Paper”.

    Excuse me, If I may… The term "Hypo" is how we refer to the first formulation of fixer, nothing to do with "Hypo Clearing Agent" which in fact removes all traces of "Hypo-Fixer" from the paper. The Hypo is best known as Sodium Thiosulfate (Modern day name) back in 1800's it was know as Hyposulfate of Soda (If I am not mistaken) I hope that gives you an answer :)

    Daguerreotypes really seem sharper and higher quality compared to calotypes. But the impact Calotype had on photography is huge, especially reproducing photographs

      Daguerreotype was technically superior to the calotype and was the first successful photographic process. They are two different aesthetics … hard to compare them.

    in a way Talbot's processes are more like modern analog photography in that it is a negative - positive process letting one make multiple prints from one negative rather than one direct positive only.

    "Hypo" ALWAYS refers to fixer, i.e., sodium hyposulfite, which is known today by its more modern name, sodium thiosulfate (ammonium thiosulfate is the primary ingredient in rapid fixers).
    "Hypo-clear" should NEVER be referred to by "hypo." Hypo-clear is so called because it clears hypo: it helps to remove fixer from film or paper, resulting in a shorter wash time. Another generic term for it is "wash-aid" because of this.

    • @Chiaroscuro1991
      @Chiaroscuro1991 ปีที่แล้ว

      The original name was hyposulfite of soda. When Talbot used it to remove unexposed silver chloride he described the process as “washing out” not fixing. Instead he used the term “fixing” when he used potassium iodide, bromide and sodium chloride to stabilize his photogenic drawings. It’s confusing to modern photographers.

    What do you mean by Hypo? Because you seem to refer to it as the fixer, even though when developing we use both fixer and hypo-clear

    • @Chiaroscuro1991
      @Chiaroscuro1991 ปีที่แล้ว +1

      Hypo refers to the old term “hyposulfate of soda” that Talbot used to remove the unexposed silver chloride. Back then Talbot referred to this as “washing out.” He actually used the term “fixing” when he used potassium iodide, potassium bromide and sodium chloride to stabilize his photogenic drawings.

    Talbot was regarded by some as a proto-patent troll, as he'd sue everyone whom he viewed as infringing on his rights.

      Or it could be said, somebody developed a process then patented it, this is a standard form of operation for inventors, he eventually removed the patent. Daguerre did exactly the same thing.

      @@mzny4314 It's more complex than that. See some of the other comments here. - And by the 1850s Archer's Wet Collodion (which was entirely unpatented) rendered both Talbot's and Daguerre's processes largely obsolete.
