Depth of Field is helpful in photography because it allows the camera to focus on the right subject. By opening or closing the aperture the place that the camera focuses looks different. The smaller the opening the sharper the object is, but when the photographer puts a higher f-number, the whole picture can become blurrier and less in focus. Knowing which number and being able to change the number depending on the subject is key to having in focus pictures.
These pictures show how the aperture changes when it opens and closes. If it’s closed the subject is very crisp, but when it’s more open then the subject is blurrier because it’s easy to shake the camera. If I would put the camera on a tripod, it would be a lot more stable and less blurry. When I tried to use the large depth of field while making the camera more stable, the picture was very nice and crisp.
These sets of three show how from further back the picture looks different while the aperture also is changing. The first close one focuses on her hand and camera, while the second one doesn’t have a subject where it needs so it doesn’t look as nice. The third one has all of her in focus and the background and foreground is a little blurry.
These pictures all have a small depth of field. They blur out parts of back and foreground so that the subject is crisp. The picture on the left is crisp is super crisp for the whole camera because it used a small depth of field. The picture in the middle somehow blurred out the front camera and just focused on the back one.
This is my favorite picture because I like how the camera is really focused and then slowly it lets the viewer see the back of the camera as well. I wish the whole camera was more in focus and to do that I would have to have a bigger depth of field. I also like how the camera is facing a little to the side so that the viewer can see the accordion part of the camera.
