Considering it's audio-software, I guess the changes are related to frequency changes. You should look up Fourier transform (the function that allows to see the sound frequencies of music, for example) applied to images and play with it. If you are not afraid to do a little bit of Python coding, you should be able to have much more control on the parameters responsible for the visual effects you're looking for.
The image equivalent of bass frequencies (long wavelength) are big details (ex: the trees) and high frequencies (short wavelength) are small details (ex: the leaves).

I haven't had to think about Fouier since college, so thanks for bringing up that trauma lmao. I do realize that there are ways to reliably get certain effects or even learn how to do this in Photoshop or GIMP, but I like the shotgunning, spray-and-pray of not knowing what the outcome will look like

I guess I find the process of going back to make small changes to the settings and then seeing how that affects the image more satisfying. Getting something that looks good is just a bonus
