I fail to understand why are you using inkscape and don't do that directly in GIMP, which is the proper tool for photoretouching. Using vectors for something that should be pixels is too problematic (mostly for printing).
It's not, because usually you export a bitmap for printing anyway.
According to my experience, I'd reccomend you to
only use vectors if you need them, and do all the photo stuff with pixels, at the right resolution.
Vectors have no resolution. This does not mean they look perfect at any resolution, of course. If you zoom in close enough, there's always a point where it starts to look too vector-y and therefore unattractive. But if you take care to make sure this cut-off point is beyond the resolution you intend to display your image in, you don't have to worry about pixels and resolution anymore.
As for advantages of using Inkscape for photos, they are the same as the general advantages of using vector editors: most importantly, everything is an object, selectable and modifiable on its own.
