Epson Scanner Input and Output

It's that time of year again; the time when I pull out my old film negs and prints and scan them. I'm working with an Epson 4490.

I scanned the above image of an outdoor art sculpture that I took in Eastern Europe.

The settings I used for scanning were: 48 bit, film, color negative, 400 resolution, Best Quality, Target size 8x12 inches, scale 100 percent.

Now guess how big the resulting Tiff file was? 91 megs!
