How do you make the explosion flashy in Hollywood movies?
Flashy explosion scenes are one of the attractions of action movies and monster movies, but in some cases, they look less flashy than you might think when you see a real explosion image.

What the experts cut out of the block ...
What a 1kg
Installed a dangerous explosive that is said to be able to blow up an airplane with only 250g ...
Turn on the detonator switch.
Dawn! It explodes with the sound, but ...
There weren't many pillars of fire or smoke, and there was only an explosion that was 'more shoddy than I expected.'
Of course, the amount of Semtex wasn't small, and it didn't explode well, but the explosion seen through the camera wasn't that flashy.
In the movie industry, using tricks to produce the flashy explosion scenes that the audience expects, it is said that it is creating an explosion that looks better than the actual one.
In the explosion I demonstrated earlier, I used Semtex, which is used in practical situations ...
'Hollywood isn't exploding for military purposes, so Semtex is too powerful,' said Stephen Miller, an explosion engineer.
In the field of movie production that emphasizes appearance, it is said that the method of achieving the maximum appearance with the minimum power is used.
Explosive fuel will be installed in these pots so that the fuel will scatter while blowing flames and black smoke as it ignites. “This creates a great, big explosive effect,” says Miller.
Also, there is no point in producing an explosion in a direction that is not used for shooting, so the pot is installed only in the direction in which the camera is located.
First, prepare a bag containing powdered explosives ...
I put a rope-shaped
Place a bag containing a small amount of explosives near the pot.
Tape it to prevent it from spilling. This fuel is indispensable for producing yellow and good-looking flames and black smoke. Most of the visual effects are produced by the fuel because the explosives exist only to ignite this fuel, vaporize it, and blow it away.
Then Mr. Miller took out the detonating cord again.
Mr. Miller cuts the detonating cord to just the right length ...
I rolled it up and made it into a pad shape.
Mr. Miller stuck the pad of the detonating cord he made to the metal block at the bottom of the pot ...
Before that, I installed a bag containing fuel. It seems that the pad-shaped detonating cord is used only as an explosive and is used to blow off fuel.
When using detonating cords and explosives, it is important that they do not come into direct contact with the pot. If an explosive explodes while touching the pot, the pot will break and scatter, and there is a risk that nearby actors and staff will be injured.
Therefore, Mr. Miller explains that a metal block is installed between them so that the shock wave of the explosion does not directly reach the pot.
Camera work is also important to convey the flashiness of the explosion.
By shooting with a zoom from a distant position, you can feel the distance between the actor and the explosion ...
You can project an explosion to fill the screen.
It is also useful to show the explosion in slow motion and to show the explosion many times from various angles to convey the greatness of the explosion.
It's also important to change the color and effects of the entire screen, Scott said.
When you're ready ...
Mr. Scott turns on the detonator switch.
Then, a tremendous explosion occurred behind.
A powerful explosion scene is repeatedly projected from various angles.
By the hands of an expert, we succeeded in shooting a spectacularly flashy explosion scene.
