Sometimes programmes are broadcast, and I assume filmed, with a very
small / invisible film across the camera / screen - noticable only
because the picture looks slightly different - sort of sharper, more
colourful and yet not as natural. I hope someone out there understands
what I am saying! What is this technique, why os it used (I personally
find it hard on my eyes to watch) and will its use increase or
decrease please?

Request for Question Clarification by juggler-ga on 20 Nov 2004 00:06 PST

Could you be thinking of the "bleach bypass" process used in films
like "Traffic," "Saving Private Ryan" and "Minority Report"?

See:

Does this sound like what you have in mind?

Clarification of Question by dtnl42-ga on 20 Nov 2004 00:58 PST

No, I have not seen the same effect in films - only on TV - on sports
highlights at the start of Match of the Day in the UK, and on several
USA sitcoms, the screen appears slightly - very slightly - different

Sorry I cannot be more specific

Help please!!!

There is a difference that is easily perceptible to the eye between
programming that is produced on tape and that produced on film.  Look
at the following linked page for one person's description of the
difference (which is similar to your description):

If this sounds like it the same difference that you notice, I can
provide some more information about it.  However, I will not be able
to get back to this question until tomorrow, so I am posting this as a
comment with the expectation that another researcher may be able to
help you further before I can.
