Replacing A ceiling Fan with a Light Fixture

Hi all. I have a question about replacing a ceiling fan with a standard light fixture. In the ceiling I have 4 wires (red, white, black and ground). At the switch I have red, black and ground (picture). So I connected the black to black and white to white in the ceiling and capped off the red. Now with the circuit breaker back on, the light stays on constantly regardless of switch position. I don't know if I need to cap off the white wire or pigtail the red wire with another. Any help would be greatly appreciated.

Thanks,
Scott
