DSLR Camera Software

The primary intended user of the DSLR camera system that is being designed for this project is the beginning to novice photographer who has little to no experience manually operating a DSLR camera. The secondary intended user is the photographer with intermediate experience operating a DSLR camera. Below, we examine the most common usage scenario for each target user.

Jim is a thirty-four year old father of an eleven year-old boy and nine year old girl. Jim’s son is an avid soccer player who is in his fifth year of playing with the local recreation league team. Jim’s daughter not only takes piano lessons where she performs in two recitals a year, but is also in her second year of ballet lessons where she participates in the annual holiday show. Jim has, up until this point, used the camera on his smartphone to record his children’s events. While this works well for the family to build their personal photo albums, Jim would like to take higher quality pictures to put in a family photo album, and also so he can brag on his children to his friends and co-workers. Jim would like to be able to capture high quality images like those commonly produced by a DSLR camera but he has no experience setting up the camera to take these kinds of pictures. Jim wants a DSLR camera that he can turn on, point at the subject of the picture, and take the picture. Jim would like to be able to capture time and location of the pictures so he can keep them organized in photo albums (Figure 3). Finally, Jim would like to be able to easily move the pictures from the camera to his computer.

Ashley is a forty-year-old working professional who enjoys landscape photography and for a small fee, takes sports team and individual player pictures for the local recreation sports leagues. Ashley knows her way around the manual operation of a DSLR camera. She has taken a couple of photography classes to learn how to operate a DSLR camera in different outdoor settings and lighting conditions. Ashley needs a camera that she can take full control of, manually setting the aperture, shutter speed, light sensitivity (ISO), whether or not the flash will engage, and focus in the capturing of a picture. Like Jim, Ashley would like to be able to capture location and date and time a picture was taken. Unlike Jim, however, Ashley would like the ability to make edits to the pictures while they are still on the camera. These edits would be relatively minor, such as noise-removal or a black-and-white filter, in order to have a rough representation of what she plans for the photos when previewing them with her clients.
