Hi there. i have D7000 with 50mm F1.8D. what would be the best camera setting for in-house and outdoor photography?

That would depend on a lot of factors. Are you doing the outdoor photography in the day or at night? Are you doing the indoor photography in the day or at night? With just existing light or with aritificial light? What do you want the photos to say to the viewer?

I'm going to go out on a limb and assume you want to take pictures for real estate sales purposes. If not, please reply to this post and say what you want the photos for.

Outdoors, I'd just put the camera into the Program (P) exposure mode. Since the house and shrubbery aren't going to be moving very fast, the autofocus setting doesn't matter much (just make sure it is set to one of the autofocus modes, not manual). Leave the white balance on auto.

Indoor, if there's enough daylight coming in through the windows, go with Program exposure, any autofocus, and auto white balance. If you have to use floodlights, set the white balance to match the floods. The camera's built-in flash won't evely illuminate a room (nearer stuff will be much brighter than the farther stuff), so don't use it. You can use an external flash with a diffuser or bounced off the ceiling or a wall.
