I want a relatively cheap but sturdy slider and tripod. My budget is 200-350 for both, I want to use them to make videos of my aquarium, some from 3-4 feet away and some from up close to try to film detailed shots of the critters living in the sand. I also want to film the aquarium from the top, like this: Camera [===============[O]================] Slider _________________________________ l l Aquarium l l ________________________________ l Any ideas on how to do this with only one slider and tripod? And how can I film the aquarium without my reflection showing up in the video? how can I light the scene?
