About the Case Studies
Each week a new case study of a picture typical of old family photographs will be published.
These examples can help genealogists learn the skills that will help date their own photos.
An estimated date (if one was not available) will be given with a +/- number of years it could be. Dating old photos is a science that provides answers usually within 2 - 6 years of when the photo was taken.
What a charming young boy. He kept his poise while no doubt being warned to stay very still by both the photographer and his parent.
Taken about 1857, shortly after ambrotypes were introduced, the technology still required the subject to remain completely still for a second or two. This could have taken longer depending on available light, time of year, and photographer's expertise.
The smooth mat over the image, with very fine punched artwork is typical of the mid-1850s. Late in the decade the mats were ornately stamped from thin foil-like sheets.
The preserver is very simple,with corners that broke easily. Beginning in 1858 they were reinforced with a triangle shaped additions to the corners.
The boy's clothes are typical of the 1850s, particularly the checked-like shirt.
His high-water pants can't be dated, but they certainly are a great addition to the photo.
A close up view reveals the fine detail that ambrotypes could produce. Also, the tinting of the boy's cheeks and lips is exquisite. The tinting art form reached its zenith in the 1850s.
