Any film-developer combination can, in theory, show true solarization. The effect is one we called re-reversal in some cases and gave rise to a 'fried egg' effect in prints where the center was darker and the edges were lighter.

If you expose a film to high intensity light with a long scale stepwedge, you can see both a negative and a positive scale.

Modern films have been optimized to eliminate solarization as much as possible.

The picture you reference does not appear quite like the solarization that I have seen. I can't be sure though.
