Knowing the type of photo can still leave a large time period, but if you know the subject of the photo, your genealogical research should be able to help you narrow that. I now turn to fashion to see if what these men are wearing can help me narrow the date range of the photo.Close examination of sleeves and collars can provide valuable information.The outline of a daguerreotype frame can be seen in some carte de visite copies.
John LAMBborn: last seen: 1881 Census, age 18, apprentice boiler maker Peter LAMBborn: married: emigrated to Pennsylvania, USA: late Jul 1886It could have been taken at the time of Peter's marriage or before he left the country.
Realising that there was a market for a process which could produce a large number of prints very cheaply, Disdéri devised a way of reducing costs by taking several portraits on one photographic plate.
This required the use of a special camera and many different types were developed.
John may have emigrated, too, but I haven't yet found him. Beaumont, 6 Park Rd, Oldham is printed on the front, but the back is blank.
So if this IS a photo of one of them it may date from, say, 1881-1886. The more full-length pose and the cut of his clothes throw me a little, and make me think it's older than the early 1880s.
