we had a white and background and a lot of light and and the iso had to be really high. and we also had to crop the photos to get out the non white things Then it worked when we had a lot of light. Click here to see my pictures: https://photos.app.goo.gl/n1L0M24DCDP2tqU13

For my group to take the photos we had to stand in font of a white background, use manual mode, and turn the ISO up. The pictures came out great and everything worked! For the black background we used the ISO and shutter speed. For the white we used the same thing except the shutter speed had to be longer and ISO higher. I think the white background was easier because there was less editing to do.
