Step 1. Observe: Study the photograph for 2 minutes. List a few things you see in the photo, then examine its features more closely. Think about who made the photo and why. What purpose might the photo serve? What visual elements or techniques does the photo use to express information?
Step 2. Infer: Based on your observations, what might you infer or conclude from the photograph?
Step 3. Prepare for Research: What questions does the photograph raise in your mind? Where could you find answers to them?
When reading an image, one thing to ask yourself is whether the image you are viewing was posed for or if the subject(s) of the photo were unaware they were being photographed.
Posed
One way to tell if a photograph is posed is to look a how the subjects are positioned. Are they standing or sitting directly facing the camera? Are they looking into the camera? The figures in the group photograph to the right are clearly posed for this picture - they are all sitting up straight directly facing the camera and are arranged so that every person is visible.
Candid
In general, subjects in candid or unposed photographs are not directly facing the camera. They may be looking at something across the room or be engaged in an activity that draws their focus away from the camera. In older photographs, when pictures required longer exposure times and therefore took longer to capture an image, subjects in motion will appear blurry. This would indicate that they were not aware a photograph was being taken and could have been captured in the background or off to the side of the real subject of the photograph.

While photographs are a type of primary source, one should always be aware of potential bias by the photographer or whoever commissioned the photograph. To determine the potential bias, it is necessary to ask several questions: who took the photograph? Why did they take the photograph?
The person who took the photograph may have had an agenda when taking it. Perhaps they wanted to show what conditions were like for a group of workers at a particular factory or they were were trying to depict urban or rural life in a particular area. Depending on this agenda, the subjects in the photo may have been either completely unaware they were being photographed or the photographer may have posed the subjects a certain way.
In the above photograph, the subjects are posed in a manner that allows the viewer to see the entire group and get a sense of how large the group was. The picture was probably taken by a professional photographer who was commissioned to document the group, just as photographers are hired today to photograph a graduating class, a wedding, or attendees at a business conference.
When viewing a photograph, you should consider who appears in the photograph, why they are in the photograph, and if it is typical or unusual for them to appear in the photograph.
Typical
From the title of this photograph and the year it was taken, one can conclude that the subjects of this photograph are in the military or were involved with the war effort during World War I. It is not uncommon to find photographs like this of various regiments, battalions, divisions, and other groups of soldiers or officers from various wars, including World War I.
Atypical
What will catch the interest of historians and archivists, and what has probably caught your attention as well, is the presence of the two women on either side of the group and the three African American men at the top right of the photograph.
African Americans
In 1948, Executive Order 9981 was issued by President Harry S. Truman, banning racial discrimination in the Armed Forces and ending segregation in the United States Military. This photograph was taken before the order was issued, which poses the question: why are three African American men posed with a group of white soldiers?
Women
The women in the photograph are a point of interest because they are not dressed in military uniform and because women at the time could not enlist in the military as soldiers, only as nurses or support staff. Given their different form of dress and the roles women historically played in World War I, these women obviously have a different purpose in this photograph.
