Dear Javier,
I've had many successful photos (both slides and negatives) from various
computer screens and video monitors.
It is essential to use a slow shutter speed (I use 1/4 second), a
darkened room to prevent refections, a cable release, a stable tripod.
If you use a light meter to measure light from the screen make sure
you take the readings in a darkened room.
You mentioned Sensia (that is a Fuji slide film w/ ASA 100, right?)
Be sure to have a darkened room and a cable release and a good tripod!
Make sure the exposure is well below 1/30th second to avoid scan lines.
consider using a doubler or a close up lens if you can't fill the frame.
If you have time, then I'd recommend doing a test roll first and
bracketing around an exposure of 1/4 second with the camera set to
manual mode. Do a series of f5.6, f8, f11, f16. Keep notes!

BTW, I'm looking for a job as a biological science research
technician. If you know of anyone who might need a technician
with my skills (see resume on my home page) please let me know.
