This photo of my brother, Stephen, was emailed to me by his partner, Joan. Digital photographs contain a wealth of information, so genealogists need to adapt analysis techniques to make to most of them.
First, what is in the picture? Just like we don’t know who the people were in old photos, future generations won’t know who is in pictures being created now unless we annotate them. Identifying when and where the picture was taken are steps to identifying who might be depicted in it and why it was taken. This photo has clues in it.
The Lonely Planet Guide suggests a holiday trip and a possible location of New Zealand’s south island. Checking WorldCat identifies the book as the 4th edition, published in September 2014. The next edition is due for publication in October 2016.
The nearly empty wine glass and coffee suggests dinner has just been eaten. It is still daylight however. The garden in the background looks green so might suggest summertime. During the southern summer in Christchurch, the largest city on New Zealand’s south island, sunset times vary between 21:11 on the summer solstice (22 December) and 19:41 on the autumn equinox (20 March).
Clothing, especially fashionable women’s clothes, can be quite an accurate dating clue. The polo style shirt Stephen is wearing has been around for decades, so doesn’t help narrow down the date.
It is harder to find information about modern objects such as wine glasses, crockery and tableware than their antique counterparts. I think wine glasses have got bigger in the last decade or so, but can’t point to any helpful reference.
If I did not know the subject, I would assign an age range 40-60. The age range and the date range the photo was taken (2014-2016) would put the subject’s date of birth between 1954-1976.
So far, the approach I’ve taken has not diverged from analysis of traditional photos. There is still a good deal more information in this digital image file.
Inside the digital image file
The format, size, shape, mountings, and annotations on the back of traditional photographs hold information useful for dating and analysis. Likewise, digital images hold useful information in metadata that is embedded in or added to the file. Viewing the metadata is possible using operating system functions (Properties for Windows, Get Info for Mac), but I prefer the free specialist image file tool, IrfanView, which offers more options.
IrfanView interface. The info button opens the Image Properties window, with IPTC and EXIF buttons, the EXIF window with button that open mapping software.
Digital cameras capture and store data in the EXIF (Exchangeable image file) format automatically, including camera settings, date, and location information.
Even without a specific date, the model of the camera is itself a dating clue. This photo was taken with a smartphone, a Nexus 5X, first released in October 2015. It was taken on 11 February 2016 at 20:07:21. My after dinner, but before sunset, assessment checks out, assuming the phone date is using the right time zone. According to the other dates recorded in the file, it does not appear to have been altered. The value for ‘Software’ often records what was used to edit the file. In this case it appears to be the built-in phone app. After I added my own annotation, the file date was updated, but exif dates were preserved.
Clicking on the ‘Show in Google Maps’ button in Irfanview takes me to the GPS co-ordinates at Golf Course Road in Wanaka and plops a marker on the lawn outside a building with arched windows. On the street map image, dated 2009, I can make out the sign which says ‘Little Italy‘, which is at 76B Golf Course Road. There is also a marker for ‘Bistro Gentil‘ at 76A Golf Course Road. The tables and windows in photos on Bistro’s website are a good match to the photo. Stephen and Joan have confirmed that they dined at Bistro Gentil.

Digital Annotation and Privacy
Although the exif data contains a time and place, there is more that I want to record in the digital image file. I want to include:
- a name tag to tell me who the subject is
- the text of Joan’s email, so I know where the photo came from and what she had to say about it
User added data is supported by IPTC Photo Metadata standard. I used the keyword field for a name tag, the Description (or Caption) field for the email contents. There are other fields available, but not all software implements them properly. These two fields are widely supported by image software and operating systems, making the tags and description searchable.
IPTC data fields in Windows file properties (centre) and IrfanView IPTC information
The description I have added contains private email addresses, which I do not want to share publically. Stephen and Joan are happy to share the photo and have given me permission, but aren’t likely to thank me if I release email addresses that could potentially be spammed. They aren’t concerned about the world knowing where they had dinner one evening during their holiday. Sometimes location is much more sensitive. Photos taken at your home with a GPS enabled phone could be more revealing than you would wish.
So, how best do I ensure that I share appropriately? Anything published on this blog could be shared on social media, quite likely by me. Facebook reputedly strips all exif data from photos to avoid privacy issues, but discards copyright data in the process. There doesn’t seems to be any easy method to remove selected exif data, and even if there was, how long would it take to edit each photo’s metadata?
Next time you receive a digital family photo, will you be looking at it more closely?

This postcard sized photograph is part of a collection of First World War photographs that were inherited by Raymond Walter Coulson (1922-1997). His father, Albert Walter Coulson (1888-1956), served with the Suffolk and Gloucestershire regiments. The cap badge looks like that of the Suffolk regiment. Although this young soldier bears a resemblance to Albert, this photo has a date stamped on the back, the 6 Feb 1917. This young man looks to be in his late teens or early twenties, so he is clearly too young to be Albert, who by then was a seasoned soldier approaching the age of 30. On close inspection I can make out the photographers embossed details on the bottom right corner:
According to the Photo Sleuth, Frederick Joseph Seaman operated a photography studio in Doncaster between 1915-1926.
So, there are some clues, which together with details of his uniform may lead to this soldier’s identification. In the meantime, I’ll remember him as an unidentified soldier.

This episode of the 50 Marriage Mondays series features a golden wedding anniversary. The couple were:
Bride: Ethel Simms Wilson, aged 28
Groom: George Herbert Simms, aged 26, a marine engineer
Date: 3 August 1904
Location: St Asaph’s Church, Birmingham
Father of Bride: Thomas Wilson
Father of Groom: George Frederick Simms
Wedding of George Frederick Simms & Ethel Simms Wilson
This is a photocopy of the wedding photograph. Apart from the couple, seated in the centre, I am sure about the identity of a few of the guests. Seated on the far right is Mary Louisa Wilson, Ethel’s eldest sister. The tiny woman standing behind Ethel is her mother, Emma Louis Wilson, nee Simms.
I think the slightly disreputable chap standing behind George is Ethel’s father, Thomas Wilson. As George was a marine engineer, the uniformed man might be a colleague, perhaps in the merchant navy. The four men to the right of the uniformed man resemble other photos labelled by various relatives as Ethel’s brothers, but I am not sure which brother is which.
Although the marriage certificate does not indicate George’s father was deceased, George Frederick Simms’ death was registered in the January-March quarter of 1897 (Wandsworth district, Vol. 1d, p. 370), and the 1901 census records Emily Simms (nee Armstrong) as a widow.
The couple were first cousins:

In 1911, George’s two cousins, George Harry Wilson and Matthew Lancelot Wilson, who were also Ethel’s brothers, lived in the couple’s household. On 3 August 1954, George and Ethel celebrated their 50th wedding anniversary which is commemorated by this photo:
50th wedding anniversary – Ethel Simms Wilson & George Frederick Simms
Again, apart from George and Ethel seated centrally, only some party guests have been identified with confidence. Seated either side of George and Ethel are the wives of the two cousins/brothers that who were part of the household in 1911. On the left is Emily Olive Pee, wife of Matthew Lancelot Wilson, and on the right is Elizabeth Johnson, wife of George Harry Wilson.
Standing behind Elizabeth is Muriel Thompson (nee Simms), daughter of George and Ethel, and behind Emily is Muriel’s daughter, Patricia Muriel Thompson, aged 16. Muriel’s other daughter, aged 9, is the laughing girl seated on the ground. The boy next to her looks about the same age, so he might be John Simms, son of John Frederick Simms.
The men are more problematic, not least because the general lack of hair makes it difficult to judge ages. I think the man of the left is Gordon Shirley Wilson, son of Emily Pee. It has been suggested that the men either side of Muriel are her brothers, Herbert (aged 43) on the left and John Frederick (aged 30) on the right. However, the man on the right looks older than 30 to me, so I think he may be Muriel’s husband, William Ross Thompson, aged 46. The man directly behind George looks older than the other standing men, so possible candidates include Ethel’s brothers George Harry Wilson, aged 63 and Matthew Lancelot Wilson, aged 58.
If you can confirm my tentative identifications or know who the other people were, please leave a comment.
