Yes, but you have to be REALLY sure you're only doing good, not damage, to every part of the photo.
The reason we wait until Photoshop isn't because Photoshop is better at strong contrast, to use your example. It's because you don't add strong contrast until after you've completely manipulated the photo so it's PERFECTLY lit. Every inch of it, top to bottom, left to right.
If you add strong contrast to a photo that's not quite ready for it, disaster happens. For example, a photo of three people ... two of them are well lit, but the third is standing in a tiny bit of shadow. If you add the strong contrast before you've brightened that person to match the other two, he or she suddenly goes from being a bit too dark to a LOT too dark.
Hope this makes sense.
It'll make a LOT more sense once you've taken the Levels Class.
