Hello, friends, welcome to this chapter.
In this chapter, we will learn about another feature of this story, Gamora, that is VLT or Backlashed
Compensation and WDR, or why dynamic range.
Most of the people are confused between these two features and many times assumes that both of them
are seen.
But in fact they are two separate features which a camera offers.
See, what is meant by BNC or backlit compensation has shown in the image, you will notice that three
percent's images are more darker, which makes them unrecognizable.
This is due to more light in the background here.
It plays an important role to sort out this issue.
Backlight composition or p.l.c. has been around for years now.
It was a huge advance to compensate for overpowering and bright lights in the background.
BNC features the video in the different regions and a different exposure is applied to each region.
This is about encouraging regions that have high level of light and maintains a normal range of light
for the objects.
The camera is focusing on has shown in the image, in the image.
Now we'll see that the foreground image or the persons, the three person images are now more clearer
as compared to the earlier few images which was not having this BLT feature.
But now there's a break now, but now there's a drawback also where you, while using this feature has
shown in the image, you will notice that now the background image is more brighter, has come back
to the earlier image.
That is where WDR or white dynamic features comes into place.
Now, let's see what is WJR or White Dynamic Range, WDR is a far more advanced version of BFC, but
the intent is the same as shown in the image.
Balser brings the object here you will see this, the BLT feature Melsa bring the objects and the people
into focus and you can distinguish who and what they are.
But the background is all blurry.
But in the real photo, which is on the right hand side.
The foreground and the background are in focus, WGI refers to the ratio between the lightest and the
darkest elements of an image counter that have WJR have to image sensor.
One is for high speed and another is for low speed.
Do capture.
They work together and provide a balanced image.
Has what you are seeing in the image, not the foreground as well as the background images are more
clearer as compared to the BNC.
Hope you are satisfied with this chapter.
See you in our next lecture.
Thanks for watching the video.
