F stop 7.1, exposure time 10 sec, and ISO 400 F stop 7.1, exposure time 15 sec, and ISO 400 F stop 7.1, exposure time 15 sec, and ISO 400 F stop 7.1, exposure time 15 sec, and ISO 400 1. the lower the f stop the more clear the image is and focused while the background would be more blurry. 2. the higher the f stop the more sharper the background is and the depth of field. 3. 7.1 f stop went well and they all came out exactly how we wanted 4. the only thing i would have done differently is use more colors and create a better image.
