"a tiny sliver of shadow", lol

Thanks for the higher res graphic.
1, The shadow is not Jet Black.
2. The shadow line is not a curtain.
3. The shadow naturally follows Lovelady's shirt.
4. The detail and associated highlighting in the entire shadow is consistent with Lovelady's shadow.
5. The level of artistry on display in the photo realistic Lovelady shadow is really a sight to behold and to think they did this not once but a dozen times with jerky, motion blurred, hand held film? Far out man, far out!
