How to get Perfect In-Camera White Balance ? – Viilage Wisdom


Hi, welcome back to Pixel Viilage and a
I am Radhakrishnan. In this episode we’re going to discuss about white balance.
It’s very important but for some reason is always taken for granted. Maybe
because we don’t understand it well enough or we think that it is not very
important because currently the trend is let’s fix it in the post. To understand
white balance, we also need to understand color temperature. The human brain has
this fantastic ability to understand color no matter what kind of conditions
they see things. They see white as white even in the evening night or day in
green light or white light. Human brains eye sees it and the brain decodes it and
tells you that this is the color. Unfortunately, cameras of all generations,
old, new and probably the one which is going to come in the future, they don’t
have the kind of ability that the human brains have. Hence, you need to tell the
camera what is white and the camera then sees everything in relation to that
particular point. And that’s called the white balance. In all possibility, it was
a scientist and not a photographer who invented the term color temperature. And
they assigned a value of 5500 degree Kelvin. Kelvin was
the unit in which color temperature is expressed, because Kelvin
is the unit of temperature. The 5500 degree Kelvin
temperature, represented the color temperature of mid noon sun, right above
your head, no clouds nothing. And the values lower, indicated a light which is
warmer, and the higher values indicated the temperature of a cooler light. The
photographer is supposed to tell the sensor or the camera, the the the type of
lighting conditions under which he is shooting. Only then the camera will understand the light in the way it is supposed to and will reproduce the
colors in the way it is supposed to. By doing this technique called white
balancing, your camera, you are telling the camera, look this is my white. Once it
understands the white correctly, then it start reading all the other colors with
relation to that particular point. In a modern digital camera, there are more than
one way to achieve a right white balance. And there are also a few other methods
using a third-party product to achieve and to override this in-camera white
balancing. So we’re going to split this video into two in the first video we’re
going to see the methods which are provided in the camera. And, in the second
video we’re going to see how we can use a third-party product effectively to
achieve a better white balance. So as usual let’s get into action. Before I
actually start shooting, let me tell you that getting the in-camera white
balancing correct is very important and very critical for the JPEG and the tiff
shooter. Not so much for the RAW shooter because he has that control while
processing those images in his raw processing software. So as usual we have
a uncomplicated setup, very simple our favorite D850, one lens tethered
using a tether cable onto our computer. We have a white light a daylight
balanced light, we have a tungsten light and we also have a flash. So let’s get
into the shooting mode. To get the white balance controls, go to the menu, find
where the white balance menu is and press, you will see a series of options,
auto, the incandescent, fluorescent, direct sunlight, flash, cloudy, shade. Then you
have the choose color temperature and preset manual. I’m going to shoot Auto
balance in two different light setups. One is a tungsten continuous light
tungsten and a continuous light daylight white light setup. Of course, we have our
favorite model Alex. Why don’t you come in. Yeah, carry that magbcuk the color
chart. Of course I cannot have any of the working lights for the setup which is
facing our model, so I’m going to switch this one off. Okay. Alex as you can see is
wearing a white t-shirt and he is against a white backdrop and he’s got
this industry standard magbcuk color chart. Which has a series of you know
pure pigments in it so any variations can be easily figured out you can
actually see the variations. In the video you must be seeing this in warm colors
because I’m using a tungsten. The white balance set for the video cameras are
5500 degree Kelvin, which is daylight. The tungsten light has much lower color
temperature. Now I’m going to take a shot using the auto white balance mode
in the camera. Okay. Here I go. Nice. Below the auto white balance mode
there are, as I told you, there are various other settings. This particular
light is an incandescent light. If you select the incandescent mode, okay,
and take a shot you are likely to get a similar result. Okay. And incandescent
light operates at 3200 degree Kelvin – 2700 degree Kelvin and thereabout. So in
the white balance setting, there is a choose color temperature option. So if
you go there and if you know the exact color temperature of your setting, in
this case, it’s incandescent and there is nothing else on the screen, I can
actually key in the white balance temperature value which is 3200.
And take another shot. And you will see similar result here. So auto, incandescent
preset and manually keying in the color temperature value all will get you a
similar or comparable result. Now to the white light. So the next setup
is white light 5500 degree degree Kelvin is the color temperature of this particular
light source. I’m shooting in auto mode. This light is supposed to mimic the
daylight. Okay, and yup there it is and since it is daylight, I can also go to
the direct sunlight setup in the white balance menu. And I’m going to see how
it’s going to work out. Oh very, nice and it is 5500 degree Kelvin. So you have the
other option going to the Kelvin and changing it into 5500 degree Kelvin. So
there’s not too much of a difference this is exactly the way the camera
behaved in the previous occasion. I want to show you something else that will
happen in the camera if you dial in a wrong white balancing setup. This is
white light okay and I’m going to tell the camera that this is not white light
and this is incandescent. Which means the light temperature is 3200 that’s how he
will understand this light as. Okay, I’m going to shoot the same image. Yup, as
expected you’ve technically fooled the camera. Instead of telling the cameras
the camera that it is a white light you told the camera that it is warm light. So
he made the necessary corrections and now you have a blue light in front. It
does the same thing will happen if you put the incandescent light and tell the
camera this is white light he will make it really really warm.
Okay, so that’s how the white balance behaved. It’s garbage in garbage out. You
put the right setup in and you will get the right kind of image
out. So it’s very important that you dial in the right white balance setting or
the color temperature setting in your camera to get the right colors out. So
this is about two continuous light source. Let’s see how it’s going to
behave with a flashlight. Okay, flashlight is supposed to be white
and it’s supposed to be a 5500 equivalent to a 5500 degree Kelvin
daylight. Okay, so let’s try and do the same exercise with a flashlight. Now we
have the flash AD600B, a TTL flash and auto white
balance setup. Okay, and yes I can see it it’s balanced right. Since flash is
supposed to have a color temperature which is equivalent to a bright daylight,
it should technically work properly even at the daylight setup. So let’s take a
look at the daylight setup direct sunlight. Okay and okay, so we have the
direct sunlight setup, yup, looks very similar and they also offer a flash
setup. Okay, let’s do the flash okay flash set up and it too seems very correct.
Now 5500 degree Kelvin is the color temperature of a white flash. Choose
color temperature select 5500 degree Kelvin and
I’m gonna do a short. Yeah okay and that too seems to be correct.
Now, let’s key in a wrong color temperature. Let’s tell the camera that
it is 6500 degree Kelvin and see what happens. Okay it started warming up the
color because it is compensating for the excess blue which 6500 is supposed to
bring in. I have, let me increase it to 7500 flash and you can see the color
shifting and the image is becoming warmer and warmer because for the camera
this light is very blue. 7500 degree Kelvin is very blue so the camera is
going to compensate and going to going to add a lot of warmth into the color to
get to your white right. What happens if you add more warm into an already white
light, this is white. We have only fooled the camera by saying that it is 7500 so
that 2000 degree difference is added into the image as warm light as a
compensation. So in the white balance setup what is left is of course
fluorescent. Since fluorescent lamp is if not immediately available to us I’m not
doing that exercise with this camera. But let me tell you that if you have a
fluorescent lamp as your light source switch the white balance set up into
fluorescent lamp light set up and shoot and you will get your whites correct. We
got out of the studio to do some testing in daylight. The Sun had gone down a bit
it was about 4:30 in the afternoon. First is white balance in Auto then let’s switch to daylight. Skin is a
little warm here the reason is you know the Sun is beginning to set now. The next
is a manually keying in 5500 degree Kelvin. Nice, it’s a little warm again. So
let’s try a 4500 degree Kelvin which is let’s say equal into an afternoon Sun
I’m just guessing. Right the white is white and the skin is brilliant. Okay
let’s move on to a shade since there are different types of shade and different
types of cloudy conditions that you will encounter in real life, I would recommend
you stay with the auto setting. Because the other setting can give you, other
presets can give you undesired results sometimes. So we saw how to use in-camera
white balance setups to get an accurate white balance. Wasn’t that simple? I think
it was simple and straightforward but not all setups are so easy.
Ask the wedding photographer, he will tell you the kind of complex situations
that he get into the kind of complex situation that he encounters on a daily
basis. There are 10,000 different types of lights on each location. In those
places, these kind of straightforward setups may not help you much.
There you will require another set of tools to kind of get an accurate white
balance in your camera. Which we will find out in the next segment of the same
video. Hope this video was useful. If it is so please let us know by giving us a
thumbs up and subscribing the channel and sharing it forward. We also would
like to hear from you, so please use the comments column below and we will be
more than happy to interact with you. And the part two of this video is going to
follow up soon. So, bye for now
