Shadows/highlights in PS 7?

[avz10]

I found this excellent tutorial on how to change shadows, etc. It included the ability to change the amount, the tonal width and the radius, BUT, I cannot find it in my PS 7.





Is this function not available in Photoshop 7? If not, is there something similar?

Sadly, I'm fairly sure the shadows/highlight dialog did not come into play until Photoshop CS.
