I have a camera and a PC. I take pictures and then take the SD card from the camera and plug it in the slot. (not very technical understanding of how this works, but it gets pictures where I can edit and post them).
I set up my tripod and my theory is I focus it on what I want to video, press record, then take the video to the computer and somehow magic happens.
No phone, tablet takes crappy quality photos and videos mostly because I can't hold it steady.
Even a few keywords I can ask google - I don't know
enough about this to know the right words to learn from google what I want to ask it.
