The use of Lightning effects in Movie


Using visual effects is a common tool used within the film industry to enhance the storytelling and magic of a film; however, applying visual effects without the correct knowledge of physics can distract the audience and pull them out of film. One example is lightning which is a common effect used to show something magical or something ominous ,and it can often be hit or miss if effects are done incorrectly.  Two films that I will be comparing for this lightning effect will be Paranorman(2012)  and X-men: the Last Stand( 2006).   Paranorman and X-men: The Last Stand ’s lightning were created using modern computer technology ,but  there are still some noticeable flaws within those scenes.


Movies with humans that have super powers need visual effects to create a believable story. It wouldn't look right or awesome if movie makers had actors in front of a green screen. One movie that  is a good example of using Visual effects to enhance the storytelling is X-men:The Last Stand. X-men: The Last Stand is an live action  movie directed by Brett Ratner and tells the continuation of mutants living in world unwanted by humans. This time they not only have to fight humans but also other mutants who want to turn everyone else into a mutants.  In X-men: The Last Stand, there is a battle scene between two mutants: Storm who  is a mutant who has the ability to control all types of weather and Callisto who has enhanced human abilities. The scene starts with Callisto attacking storm and the two fight it out ,but Storm gains the upper hand and throws Callisto into a metal fence. This intense scene ends with Storm killing Callisto with her lightning.

(please go to 1:00 for scene) 

The effects in this movie was created by Genarts who used a program called Sapphire plug- ins which is a program that creates organic and credible lighting bolts. The artist has the ability to insert any type of lightning they want, manipulate how it moves  and even apply it in a 3-D space. For this particular scene, the artist applied the lighting using Sapphire’s Zap onto the shot. Second, the artist applied a glow spark and added some len flares to volumized the lighting properties. Finally, the artist combined all the effects together and layered it onto the shot. Although the effect sounds very easy to create and the scene looks well done. There were some problems that were noticeable as I was evaluating the shot. Some things that I noticed are the bad lighting, flatness, and invalid movement of Storm’s lightning. If look upon closely, the lighting is wrong and the strongest source of lighting appears to be coming from behind the building. Lightning is a huge blast of light and should be the strongest source of light in that scene but if you stop the clip at 1:09, you can see that the foreground isn't even lit.  Although the artist was able to use realistic lightning to apply to the film, it still feels really flat as if the lightning is just applied top like a sticker. It doesn't feel like it moving through space. In addition, the lightning doesn't feel correct when Storm hits Callisto with her lightning. Lightning moves through the body through the shortest routes but in that particular shot, the lightning is just placed on top of her and doesn’t look like it’s surging through her body. Disregarding the flaws of the effect of that scene, I do feel that the lightning was successful it terms of storytelling and getting the point across.
The lightning looks flat and doesn't feel like it's moving through space

Lighting is off! Strongest source should be coming from right not behind the buildings


An example of how Sapphire works. 

The movie Paranorman is an 3D stop- motion animated Horror created by Laika Studios. It revolves a boy name Norman who has to save his town from man-eating zombies while also learning the lesson that it’s okay to be himself. In one of the scene, Norman encounters Aggie, who is the cause of the curse on his town, and has to convince her to stop the destruction. Aggie is shown as a yellow flying ball of erratic energy and has the ability to blast lighting out. Looking closely at the lighting there are some qualities that stand out such as the soft and fading blast of lightning coming from Aggie which makes her feel almost ghost-like.  Interestingly, this effects was created using several methods and by several departments at Laika studios.

Here is a scene of Angry Aggie:

The process begins with traditional and handmade effects. One artist created 2-D ink splatters and another artist microwaved CD to copy the organic shattering then layered it with the animated effects. Secondly,  they created a stop motion armature/puppet that had a glowing head to have a luminescence. Afterwards, They applied visual effects of animated lightning bolts to put everything together. This animated effect  was quite successful for this type of film. I felt that it added texture and enhanced the look of the scene and gave great story to the character of Aggie. This effects although animated quite well has some flaws with the believability of the lightning. Some flaws that are visible are the color and movement of the lightning. The color is too neon yellow whereas real lightning is bright white. There is also not enough erratic movement in the lightning and feels too slow at certain parts. It’s almost as if the movement feels like ink splatters instead of quick unpredictable movements. If the animators  made the movements a bit quicker ,then the feeling of lightning would be brought out  more.


Artist using traditional medium to create the feel of Angry Aggie


A puppet with a glowing head and clothes was created to ground everything


Then lightning effects was layered on last

Overall, both the lightning effects of each movie did their best to create a believable type of lightning but there are still some noticeable flaws.The effect in Paranorman was created using a hybrid of traditional and computer effects which created an interesting look, but the lightning was not the right color and some movements were off . The film X-men 3 created the lighting using the computer program sapphire to layer on top the moving lightning which created some realistic lightning ,but there was some incorrect placing, movement, and lighting. Despite the flaws, both movies created lightning to tell the story and still get the idea across which in my book is better than having an effect that looks good but does nothing to tell or push the story.
