I should have done a setup photo for this but I did not.
I raided the girl's toys again for a photo. This is a cheap spinning toy that they got at Christmas. I thought it would make an interesting photo.
I used a clamp (like you would have a on a tool bench) to hold it upright. I used another type of clamp to push the button to turn it on. To cover the clamp I used a black tshirt.
I did adjust the exposure outside the rings a bit using the radial filter in Lightroom to make it darker.
