We have received quite a few messages about how to shoot the solar eclipse next Monday, August 21st 2017 in slow motion. After all the more frames you capture, the more temporal detail that will be preserved but there is a threshold when diminishing returns from shooting high fps take a toll on image quality, dynamic range and color accuracy.
In short, the rule of shooting the total solar eclipse at high speed will be based on timing on one hand and detail retention on the other. We have found in our research that you really do not need more than 120fps in order to get a great solar corona snapshot with enough detail and variance. 24 and 30fps regular frame rates are also good and perfectly acceptable.[...]
