Hola chicos, bienvenidos a nuestro tutorial de Corrección de color... #barra
y Gradación de color.
Hoy te vamos a ensenar como grabar tu película y hacer que se vea mas...
profesional, aplicando primero corrección de color...
y gradación de color.
Entonces, empecemos con
como grabar tu película adecuadamente.
Aquí estan las cosas que necesitas
una camara que te permita ajustar la apertura, balance de blancos y niveles
de ISO.
Programa de montaje (edición)
Yo usare Adobe After Effects, pero cualquier programa de edición te permitirá
realizar la corrección de color.
Voy a usar también algunos de los programas adicionales de corrección de color de Red Giant:
Colorista II
y MagicBullet Looks.
No necesitas usarlos necesariamente,
pero te ayudaran a realizar la corrección y gradación de color
facilmente.
En caso que tengas imagenes 'ruidosas' o quisieras limpiar el video...
te recomiendo Neat video,
un programa de reducción de ruido.
Empecemos con grabar la película, sera divertido y fácil de gradar el color.
Antes de que presiones el botos de grabar
asegúrate de ajustar tu balance de blancos,
si tu cámara te lo permite.
Nosotros grabamos con una Canon DSLR
y en estas camaras es tan facil como sostener algo completamente blanco
delante de lo que intentas filmar.
Tu también puedes usar una tarjeta gris o algo simple como una hoja de papel blanco.
Luego tomas una foto..
vas al MENU,
seleccionas personalizar el balance de blancos,
seleccionas la imagen y presionas Configurar (SET).
Ahora cuando tengas tu balance de blancos 'personalizado' ,
la imagen estará propiamente balanceada con tu actual configuración de luz.
Recuerda cada vez que cambies la configuracion de luz, tendras que reconfigurar tu balance de blancos.
Solo toma unos quince segundos y vale la pena!
Luego: Nosotros siempre grabamos con un perfil de figura plana. Usamos 'Cinestyle Picture
profile'
y lo que esto te permite es reducir tu enfoque y contraste..
en tu cámara, y eso
te permite corregir y gradar luego en pos-producción.
Si no dejas que tu cámara haga esto por ti..
tu imagen probablemente tendrá mucho contraste para gradar luego.
Film Riot hizo un episodio en estilos de imagen
y nosotros también dejaremos su enlace en la descripción de este vídeo.
Luego debemos exponer correctamente la pelicula.
Si deseas asegurarte de no sobre exponer o subexponer tu imagen...
..En caso de que tu cámara no tenga suficiente gama dinámica, para capturar ambos tus sombras y..
tus toques de luz(reflejos) adecuadamente..
...nosotros recomendamos que te asegures que tus toques de luz( highlights) no estén sobre expuestas.
Es mas facil aumentar un poquito mas la luz en tus sombras y eliminar el ruido,
porque cuando tu imagen esta sobre expuesta.. no habrá data para trabajar.
Por ultimo,
con el fin de asegurarte que tu imagen esta enfocada..
nosotros usaremos un zoom digital para enfocar su nariz y ojos..
enfoca y luego quitale el zoom.
De esta manera,
tu siempre estarás seguro que tu imagen esta 100% nítida
y enfocada.
Ahora que ya grabaste toda tu película adecuadamente,
nosotros vamos a corregir el color.
Ok. Primero evitemos la confusión entre corrección de color
y gradación de color.
Generalmente lo describen como si fuera un mismo procedimiento,
y aunque ambos tengan algo que hacer con el ajuste de color en tu imagen...
..no sirven el mismo propósito.
La Corrección de color corrige los colores en tu imagen.
Suena obvio,
porque lo es!
El objetivo de la corrección de color es asegurar que todas las imágenes consecutivas
en la escena o el vídeo estén parejas.
Eso significa que el balance de blancos tiene que ser el mismo, la exposición, los verdes, los azules, rojos, todo.
Veamos un ejemplo:
Esta escena es de nuestro mas reciente video titulado: 'Snowly',
como puedes ver todas las escenas tiene el mismo angulo, la misma ubicación..pero aun así tienen...
...colores totalmente diferentes.
La escena de la izquierda es muy anaranjada y muestra una apariencia muy cálida
mientras que la escena de la derecha muestra una apariencia mucho mas fría y gris.
No te preocupes. Para eso esta la correccion de color.
Personalmente, yo prefiero la apariencia calida de la escena de la izquierda..
.. así que, voy a ajustar la imagen de la derecha con la de la izquierda.
Antes de hacer eso,
primero voy a corregir la escena de la izquierda rápidamente.
Voy a agregar niveles a la escena y asegurarme que los negros sean tan oscuros como...
sea posible y que los blancos estén tan blancos hasta antes de que se sobre exponga.
Lo bueno de usar niveles, es que puedes ver que colores están empezando a
By just bringing your arrows a little to the middle and make sure that they don't
clip.
You can see if they clip when they pass over one of the lines.
Now you can use the middle arrow and push it in any direction
to get either more or less contrast.
Now if you click the drop down menu
you can select either of the three primary colors.
Let's select red
and make sure the snow isn't orange, but white.
To get the most proffesional look
you want to make sure that your whites are white and your blacks are black,
unless you're going for a very stylized grade, of course.
There; we messed around with the primary colors a little bit
and the image now seems well balanced.
This is a good base that we can grade.
But first;
let's correct the other shot
to match up
with this one.
We're starting the same.
We're pushing the shadows down a little bit and pull the highlights up a little bit.
Now we'll go in the red channel
and pull the red highlights quite a bit up.
Also, the midtones of the red should go up a little bit.
Now we're going to do the exact same for the greens.
Lastly; we notice that the blues pop a little bit more in the first shot so let's push
these down a little bit as well.
The first shot seems to be a little bit more saturated,
so let's add Colorista II,
push the saturation to about five (5)
and give the midtones a little bit of an orange hue.
And there... Now the shots are quite well balanced.
We can't get them exactly right because the sunshine seems to have moved around
a little bit as well,
but once were done grading it and have another shot in between.
no one will notice.
Although this was quite an extreme case
you want to make sure that you color correct each shot and that expecially shots that follow
each other are well matched
and the color's aren't off.
Let's take another quick look at another example.
This is a clip from 'Scratch'. An upcoming little three part webseries that we've
been working on for quite a while.
In this scene it is supposed to be night.
There's some light creeping in from the hallway, but only that would not be
enough to properly light our shots.
In order to keep the ISO low and the shutter speed a little higher we just lit the scene
lot more than you need for darkness.
The original shot doesn't look like it's dark at all.
So we simply played with the levels a little bit. That way we keep details in our shadows
We lost some of the light as we make sure the highs and lows don't pop as much
and with our final color grade it already looks way more convincing.
So. With all your footage properly balanced it's now time for some color grading.
Back to our initial two shots from 'Snownly'.
First I am going to pre-compose the layers I have applied my color correction to.
Then I am going to apply 'Magic Bullet Looks',
a great plug-in by Red Giant Software.
I highly recommend getting this one.
I'm going to select a preset that the plugin came with called 'Bistro City'.
With that open I'm going to turn off some of the corrections this pre-set came
with.
I am shutting off some of the diffusion filters and make sure there is a lot
less contrast.
Next, I'm going to play around with the lift/gamma/gain a little bit
I'd rather have a little greener shadow instead of blue
and I really want the skin tones to pop a little bit more.
Speaking of pop,
I also add a pop filter.
This allows me to make the natural color contrast in
the image pop a little bit more.
Finally, I am also going add a three-way color wheel
and push my highlights a little bit to the blue side,
my midtones up a little bit and the shadow a tad to the green side.
I also want to make sure that I don't lose too much detail in the jacket
so I will pull the dark tones up a little bit.
I am also going to saturate my image a little bit more.
About a hundred five percent (105%) should be fine.
Still feels a little bit too dark for a sunny, snowy day.
So I'm adding another levels filter to boost the midtones and highlights up a
little bit,
Since we did our color correction properly, we can simply copy/paste (ctrl+c, ctrl+v)
our grading to the other shot and immediately we've graded our second shot as well.
I want to boost my saturation on this shot just a little bit more, and there
we go.
We are done with our first grade.
Since we toyed around with the colors quite a lot of I notice a little
grain on the jacket however.
This is where the 'Neat Video' plug-in come in.
I just added it at the top of our grading chain, click options.
The plugin works fully automatic if you want it to.
To make sure the image does not look so faded,
I just add an unsharp mask filter and that should look very clean.
We shot this with a 50 millimeter lens without image stabilisation.
I do notice a few minor shakes in the shot. Not to worry.
I'll just add a 'warp stabilizer' and put the smoothness to about two percent (2%).
That is more than enough to take out the minor shakes.
Let's also grade our day for night shot.
I'm going to yet again for pre-compose our correction
and add 'Magic Bullet Looks'.
I am then adding a very little pre-set I made.
It's just a pop filter and a lift/gamma/gain filter.
It makes the shadows a little bit more greener and the highlights a little bit more orange,
I feel that the mask fades away in the darkness a little bit,
so we have to do something about that.
I want it to pop and look a little bit more scary.
Let's duplicate our layer and duplicate it on the project file as well.
Now let's take away our color correction and our color grading.
Now the mask is much more white.
We'll then just make a quick little mask around the skull mask
and fade it out to about fifty (50) pixels and expand it inwards fifteen (15) pixels.
Now let's quickly go through the clip and make sure the masks stays with the skull mask.
You can also do this with the faces of your characters to make their skin tones pop
a little bit more.
This type of color grading is a little bit more advanced,
but you can get some great looking footage with it.
All it takes is a little masking.
With the masking of the way
the skull mask looks like it pops way more than befor and it looks much more
intimidating.
I have one more example of specific color grading.
Here we have a clip from our Monday Challenge: Star Wars video from
some time ago.
The normal clip looks
pretty bland, so let's quickly turn on the color correction for it.
I increased the exposure a little bit,
I pushed the shadows a little bit to the dark side...
I mean... I mean.. the blue side.
I pushed the midtones a little bit to the orange side
and made the highlights a little bit more blue.
I also increased the saturation to forty (40).
Here's what I did to the eyes.
I simply masked around them individually
and applied a different color grading to it
to make sure they pop way more
and are a little bit more green and bright.
We then apply our final color grade to that.
In this case I applied my color grade to an adjustment layer
to grade all the footage at once.
If I think the grade is a little bit too strong
I just take down the opacity of the (adjustment) layer a little bit.
In this case about sixty percent (60%) or so.
Finally I added some film grain, sharpened the image a little bit and there's our
final shot.
So guys,
I hope you learned something about color correction and color grading today
and that with it
you can really move your videos to the next level.
There is really no limit
to what you can do with good color correction and color grading.
You can even make your image look more cool...
Or way more warm.
