Well, 24 bit is 8 bits per channel (red green and blue), which give 2^8
bits, (256 levels), of color, 48 will store 16 bits per channel, giving
2^16 (65,536 levels).
IIRC it doesn't increase the color depth, just increases the gradations
between the existing minimum and maximum, but it will allow more
manipulation of the files before the image begins to break down.
The downside is that using that setting will probably more than triple
the size of the scanned files, especially if there's no compression
being applied, when they're being scanned, and even if they are
compressed on disk, those files will take up considerably more room in
memory, when they're unfolded by your image processing software, and tax
your machines processor(s).
I know you have a fairly new PC, but if you have only, the minimum
memory for Win7 there will certainly be a performance hit.
On the other hand, raw files from your K-5 when Elements opens them are
handled in memory as 16 bits per channel even though the camera only
records 14 bits, so you may not see any real difference, (depends on the
megapixel equivalent the scanner is producing).
I'm not sure what color smoothing might be doing. I assume that it's
applying some algorithm to make for a more organic looking transition at
color boarders. Since I'm not sure what it might be doing I can't
really say whether it's good or bad, but either way it probably isn't
making the file sizes any larger.
You should really try doing a couple of scans of the same color slide or
negative, (preferably one with lots of detail), with color smoothing
applied to one and see which one looks better.
It's been a long time since I actually scanned any film and can't
remember what settings I finally decided on.

24 bit versus 48 bit color settings...
color smoothing? what does that do for ya?
what do you guys do? I've been using 24 should I up it? NOw that I
have elements 10 andam on Win 7
are there any downsides to going to 48?
I'm working on my alaska calendar for 2016 lots of scanning here
While I'll be making a larger on efor myself on my printer, I'm going
to also publish on cafe press in standard size
thanks
