Hi everyone. I have Manfrotto MA055CX3 carbon legs and a 501hdv fluid head. I shoot a lot of shows and I'm usually center in the auditorium. For a while now, I've had a weird problem. If I'm shooting center, the footage is level, but when I pan left or right, the image starts to tilt. The only way I can describe it is if you look forward, then slowly turn your head but also tilt your head sideways while you do it. Does anyone have any thoughts on why this may be? I feel like everything is locked down on my tripod. Whenever I engage the leveler to rise up or down, it does have to become loose, but I'm just perplexed as to why the tilt is so extreme and I do tighten it back up when I'm done adjusting. Thanks!
Your tripod head is not level. The head itself is probably tilted up, but you are using the "tilt" feature of the head to bring it down. When you are pointing straight ahead, it looks level. But it isn't.
If the head doesn't have one, you should buy a little round level and attach it to the head.
