The camera method is probably the method best understood by people, and most utilised by others. I think so long as the limitations of the method are understood and minimised it is a useful tool. If in the future we get 1000fps capture with good resolution, then potentially the camera method could be the premiere approach, however it seems that interest in high frame rate capture has petered out.
Once again, using an additional program to streamline the results processing makes it much more achievable to obtain large numbers of results in a realistic time frame.Â
