filenames – Correct way to name files

What would be the best way to name an image if I want the title to display values ​​such as date, time, ISO and shutter speed?

What I do is take similar pictures while changing the ISO speed or shutter speed (at the same spot, 10 seconds or less between shots), and then name them as follows:
yyyymmdd-hhmmss-ISO-shutterspeed.jpg

Since I am learning to take pictures, this method allows me to access files chronologically on any device and to see the differences that exist between them. However, it is so that I named my homework in high school at the time when the documents could not be more than 12 or 24 characters and absolutely no spaces (I do not say that I 'd do not say it). I invented the format, it's just the one I use).

Is there a more practical / effective way to achieve this?
