The "Films Using Them" section should be removed, as it gives the false impression that there is something rare or notable about films using HMIs. Almost every one of the dozens of movies I've worked on has used them. El Mariachi

[edit] Etymology

I reverted out a change that someone made linking the "Hydrargyrum" in the keyword to mercury. If this was done to show the etymology of the name, we should probably just create an explicit "Etymology" section instead.

I don't think the etymology needs a whole section to itself, but since Hydrargyrum is a very uncommon term for mercury, it's more important to have a link for people who don't know what it means -- they wouldn't necessarily guess to follow the mercury link. Maybe a parenthetical? It looks a little clumsy. El Mariachi

Nice!

[edit] Green spike

The reference to correcting the 'curse' of the HMI green spike is problematic for two reasons. Firstly, as a working gaffer I find that DoPs much more often want to warm up HMI's, specifying gels such as 1/8 CTO, 1/4 CTO or Pale Amber Gold, than to cool them with CTB as suggested in the article. Secondly, if the idea was to compensate for a green spike the correct gel would be 1/8 or 1/4 Minus Green as used on some practical flourescants. CTB does not correct a green spike.
