Maybe you can answer a couple beginner questions I'm having about Lightroom 3.

1) How do I do a horizontal crop of a vertical picture, or vertical crop of a horizontal picture? It seems like the software won't let me do this.

2) When I move a picture from Lightroom into Photoshop, convert it to 8 bit, and save it as a JPEG, it seems to be clipping my highlights. Any idea why, and what I can do about it?

Thanks.
