Levett Landon Boscawen Ibbetson

[2][3] From his London home (46 Margaret Street, near Cavendish Square),[4] Ibbetson corresponded with William Henry Fox Talbot in 1842,[5] having spent some years trying to produce a lithograph from an original daguerrotype, writing "I have been going on with experiments in the Callotype & have had some very good results as to depth of Colour."

"[7] An enthusiastic geologist, one of Ibbetson's finds on the Isle of Wight, the fossilised remains of a Hybodus, was sent to Sir Philip Malpas de Grey Egerton, and was discussed in the Proceedings of the Geological Society in 1845.

[8] During the 1840s, Ibbetson was also engaged in various geological surveys associated with the expansion of the British railway system, during which work he corresponded with eminent geologist Henry Thomas De la Beche.

[9] He wrote a book, with contributions from Edwin Lankester, published around 1852, entitled Notes on the geology and chemical composition of the various strata in the Isle of Wight ... With a map in relief.

[11] His illustration of a fossil, "Transverse section of madrepore" in The Westminster Review of September 1840 is credited with being the first example of the use of limelight to shorten exposure times when making daguerreotypes.
