Q: 1. Will you need to remove this filter during the total eclipse to see & photograph anything?

A: Yes, solar filters are designed for shooting the entire sun and partial eclipse phases. You will need to remove the filter during totality to photograph the corona. If you also want to photograph Bailey's beads and the diamond ring effect, you will want to remove the filter about 20-30 seconds before totality begins and replace it about 20-30 seconds after totality ends. This will not damage your camera equipment. Another answer implied that it is safe to view the eclipse through your camera's optical viewfinder with this filter in place, but that is NOT the case. This filter is NOT certified for visual observation. Place a viewfinder cover or a piece of tape over your optical viewfinder as a precaution, and only use live view to focus and compose your frames.
