Details:
I have always thought that h-alpha solar videos look more realistic when the videos are inverted (dark areas made bright and vice versa). Inverting makes the solar surface seem more realistically 3D with brighter highlights and darker depressions. Also, solar filaments are darker because they are higher and cooler than the underlying chromosphere. I wondered if the darker patches on the chromosphere surface are likewise cooler and higher with the brighter patches being lower? So, I made a 3D animated computer model using one of my h-alpha videos. This model was painted uniformly gray and then had its surface adjusted to match my video with darker areas being higher and lighter being lower. I then shone a virtual light at the model to bring out the terrain relief. The resulting video looks pretty realistic but is probably not a true representation of the chromosphere topography (or is it?). Original video is also shown.
