Actually, no. I've got some old software (Photoimpression) that has three sliders that allow you to adjust the intensity of highlights, shadows, and what's in between. That result is from adjusting the middle slider down. It has a way of increasing contrast without blowing out highlights or darkening shadows too much.
Kinda funny, as I have other photo editing software, some of which even allow you to define any random equilization curve ... but I can get decent results a lot easier with that slider.
