This picture has been taken with a SONY camera. We have no details about the orientation of the camera.

The camera stores the pictures on an internal memory card.
It names them following the pattern DSCN four digits and the extension.JPG where the four digits represent the number of the file.
The file we are concerned with is named DSC02048.JPG.
A search for the same filename in our local computer gives 5 results. The search took 0m 23.009s.
In the 5 results, one image is the exact copy of the picture. It belongs to a folder that contains 29 images, the exact same amount of pictures as in the picture folder.

The format of the picture is a JPG standing for Joint Photographic Experts Group. When compressing the jpeg format, the resolution of the color data is reduced, usually by a factor of 2. The Joint Photographic Experts Group thinks that the eye is less sensitive to fine color details than to fine brightness details.

The colorspace of the picture is RGB. It contains 3 components Red, Green and Blue. The components are evenly distributed. The standards deviations are close to the means. The kurtosis and the skeweness of the components indicate an even distribution of the left tail and the right tail of the values. Therefore the image doesn’t show big contrasts and is dark. It is probably taken in an interior or in the shadow. Most of the images of the folder follow the same pattern.

The level of skin colors is low, there is probably no nudity in the image. Or at least, nudity is not the main subject of the picture. In opposition to 63 percent of the pictures that contain a significant amount of skin colors. Two photographs in the same folder contain a large percentage of skin colors in their center. They are taken at 23h41 and 23h42, one hour and 45 minutes after the picture.

There are 172 corners present. This level indicates that the picture may have been taken in a built environment. There are 3 faces positioned at (xx,xx), (xx,xx) and (xx,xx). They occupy a portion of xx% of the image. One at the lower left corner and two in the upper half of the image. The distance between the tree rectangles is in average xxx. The people are close without touching each other. The proximity of the photographer and the position of the face in other pictures prove that the photographer moves easily among the circle of people photographed.

It is dark now. It is the end of an evening of November 2004. And the face in the center of the image receives more light than the one next to it at the right side. Two hands are close to the second face poorly lit. An image begins to form in the back of your mind, and we have only started counting.
