lens filter

what is it?
simply put, lens filter is one of the most powerful and versatile effect plug-ins for iMovie you’ll come across. in the ‘old days’, people (usually pros, but nowadays casual users as well) used translucent colored pieces of glass in front of their cameras to alter the light that enters the camera. this allows them to achieve dramatically better looking footage, as well as establishing color schemes. using these filters was (and is) so common, that their name has carried over to iMovie – effects were called ‘filters’, and throughout Apple’s documentation (for developers) an effect is still called a filter.

one of the most common, and basic filter (and one that everyone should have) is the skylight filter (a slightly pink filter) which makes the skin tone look much warmer. likewise, blue filters are used when shooting indoors to counter-act strong incandescent light.

also very often used (especially with moving media), are graduated filters. you will definitely have seen the effect of such a filter, even though you might not have noticed it. they are most commonly employed when shooting outdoors to make the sky look blue (which is usually doesn’t because the sky emits too much light, and turns out to be white on film/digital media).

our lens filter plug-in can create this (and millions of other) effects after you have shot the movie, allowing you to correct some, and enhance most of your clips. because of the freedom digital medium (and iMovie) gives you in post-production/processing, ‘lens filter’ can create effects that you can’t create in the field. furthermore, since iMovie allows you to undo a filter effect, you can experiment with filter at your leisure – not while your cast and crew (or mother-in-law) is waiting.

this defines the second color in a left to right transition (right color), or top-down transition (bottom color). it is ignored if you choose to use only one color, or load a picture as color source.

note:

this effect cannot replace a polarization filter. if you are shooting footage close to water, or

desert scenes, you will still need a polarization filter.

please note that we also recommend you still get yourself a good (of cheap) filter and always use it while shooting outdoors. the reason is simple: a filter can do something our effect can’t: it will protect your lens. spending $5 on a simple (yet good) filter will save your $100 (or more) lens when shooting outdoors.

finally, our digital lens filters work different from physical filters – they work on already shot footage, and usually slightly decrease the overall brightness.

 

 

what should I use it for?

  • digitally enhance your footage
  • create color schemes / color themed footage (e.g. to distinguish between ‘now’ and ‘flash-back’ scenes.
  • brighten a clip’s ambient light
  • make a clip ‘colder’
  • dramatically enhance scenic footage

note:
a filter consists of two parts: the color information, and the strength map. please read the ‘lens filters – how they work in iMovie’ section of the manual for an in-depth description on how to use them.

 

color 1
this defines the color part of the filter (if you use one color), or the first color in a left to right transition (left color), or top-down transition (top color). it is ignored if you choose to load a picture as color source.

  • place inside the active rectangle. color one is at it’s left edge, color 2 at it’s right edge (even if the edges fall off-screen).
  • two (vertical)
    the color of the filter is a top to bottom transition of color 1 (top) to color 2 (bottom). the transition takes place inside the active rectangle. color one is at it’s top edge, color 2 at it’s bottom edge (even if the edges fall off-screen).
  • picture
    the color information is taken from a picture that you load from disk. the picture fits he active rectangle exactly.

 

set strength button
this button enters the strength setup dialog that allows you to set the filter’s strength map (see below).

dissolve
this slider either sets the strength of the whole filter (when using a flat shade filter), or the length of the transition between maximum and minimum filter strength.

minimum
this slider sets the minimum filter strength.

maximum
this slider sets the maximum filter strength.

filter strength setup dialog
(please see the manual)
this dialog enables you to quickly generate more than a million different strength maps to use with your filter.

this dialog enables you to create filter strength masks or strength maps (very much
