Define "negative enough"?
As I said, I'd call -2 degrees more than enough for most eventualities. You would only want more if it was a track slag.
You can't just blanket camber as being bad just because it might give you uneven wear, it really isn't that simple.
I've run -1.75 deg camber on my car for a good few months on the road driving enthusisatically. My tyres have worn completely evenly, because the toe is neutral (I would have prefered some toe out if on track though). You have to take into account that camber migration depends entirely on the amount of suspension travel you have so I maintain my viewpoint of "it isn't that simple".
Also got to take profile into account as a lower profile tyre is going to have less give in the sidewall, which will contribute to uneven wear. However, on 195/50/15s the sidewall is a reasonable size and there is enough give in the wall for the whole tyre to remain in contact with the road at all times. I would only have a concern if you drive at high speeds in straight lines all the time as you will heat the inside up more than the middle or outer parts of the tyre.
