Summary:

Is grateful for referring him to Capt. Ludlow. Has now moved himself to Falmouth. What does JH think of the chances of success of a popular book on photography? He is contemplating the idea. Hears that J. B. Biot considers the production of colored drawings impossible, but is not convinced himself. Encloses description and drawing of a very clever instrument.

From:
Sir John Herschel
To:
Robert Hunt
Date:
[20 February 1841]
Source of text:
George Eastman House, 5.17
Summary:

Unable to give any specifics concerning Louis Jacques Mandé Daguerre's new photographic process. Discovered that old paper specimens produced a much better representation of the spectrum in its natural colors than those obtained at the date of JH's paper; these results are 'light on a dark ground,' which makes JH more hopeful that colored photography will someday be perfected. Has experimented with vegetable substances.
