For this assignment, I went around my house to find good lighting by the window that would illuminate my subjects but not the background if the image was underexposed. Finding the right area was difficult because in many of the rooms in my house, there is light coming from multiple directions, so I could only use a limited few spaces. I used a tripod for every image because with different shutter speeds, the final image might be blurry if I moved the camera at all.
The only image I had to use artificial lighting on was the first image of the fish. For this photo, I used the lighting from the fish tank, which came from above the fish and only illuminated the top, allowing most of the background and the bottom of the fish to be dark. I also had to make the shutter speed pretty fast because the fish were swimming around and I needed a solid photo where they were still. For the middle three images of flowers and wood, I had the subject directly in front of the window and shot from the side so that the background wouldn't be the part of the room where the light was shining and the background could appear dark. For the final image of the butterfly on flowers, I stood right in front of the window and shot in the direction the light was heading. For this image, the background was difficult to make dark because the light was shining into the room, but I was able to make it black because the light on the subject was harsh enough.
The article was helpful because though I already knew about aperture and shutter speed in exposure, reading it was a good reminder of how important they are to a photo, especially when the subject might move. The part about ISO was a good reminder because I often forget to change the settings for ISO, even though it is important because it can change the final image's color or visible noise.
