There are DP's I work with (when shooting RAW) that tend to "overexpose." There isn't any clipping, however, they maintain as much detail in the histogram to increase the dynamic range. Then crush it in post.
Then there are DP's I work with that shoot everything they possibly can in camera, including there final looks, essentially leaving almost nothing left to do in post. I guess it all depends on how you work. I think the guys you stick to "in camera" have more confidence but at the same time, the guys who leave it up to post have more versatility when it comes to pleasing the client.
There are pros and cons to both methods, just find a method that suits your workflow.
