Yes, that's right. The iSis in "UV-included" mode scans 2 rows at time
with the normal "white" LED illumination and then goes back and rescans
these same 2 rows with the normal illumination off and with a special
UV-emitting LED illuminant turned on. If all you're looking for is
Ouch ! Pity it doesn't have the option to do it the other way, run with
both the white and UV illumination for UV included, and just the White
for UV excluded. I would guess that the problem is the illuminant doesn't
match the previous Eye-One incandescent lamp, a disadvantage of the
move to the "bumpy" LED illumination.
Well, nobody said these decisions would be easy! :-)
But seriously, at least buying two Eye-Ones is cheaper than either an
iSis, DTP70 or Spectrolino.
I can't really understand why the Eye-One doesn't come with
an interchangeable filter like the Spectrolino - optically
they are the same arrangement. There is not even the allowance
for the extra calibration information needed.
