The short answer is yes. You cannot perform many operations in PS
without changing to 8 bit mode.
In PS 6 certain filters are available in 16bit like Unsharp Mask, and
Gaussian Blur and a few others.
As many histogram adjustments as possible should be done in 16 bit but
some tweaking of the histogram can be done in 8 bit mode if needed.
Switching to 8 bit is not necessarily a "bad idea" simply because it is
