hello today it’s so unusual a little bright even I look explain why today I’ll tell
an interesting topic and in this case I wrote an article about a year and a half ago called
myths about filters for underwater shooting in this case these are filters that change
the color component, that is, it’s orange or purple filters for blue water I would like
to explain the physics of the process and clearly show what is the big mistake and delusion
of those who say that by putting on a filter we add red, let's look at the physics of the
process, I'll tell you how the filter actually works under water with immersion to certain
depths and we will look at this on the graph, so we look at the surface of the water in
our case, any of our video cameras or cameras in the video shooting mode puts the colors
of the three colors red blue and green on the surface of the water they are in our 100%
option, that is, they are our floor and then we take what we submerge under water submerge
about n and 5-10 meters what happens next, the sunlight that passes through the water
column loses a component such as red, it passes least of all into the depths of the water
column, therefore it is lost the fastest and most often we notice this when we see blue
and green everything and there are two a solution to this problem how to make your blue green
shooting color the first option how people think we take a light color color filter orange
put it in front of the camera we get a color picture until you get a color picture but
what happens when I communicate with people I always ask you know what happens under water
when you put an orange filter, they answer me of course we know we install a filter and
add a red one, and in this case I ask the second question, where did you get the paint
from there, that is, it disappeared at a depth of 10 meters for a certain amount and here
you suddenly they took put a filter added red says the player where he got from where
so let's figure out what happened Okay, we take a filter and in this case we do not add,
just we cut the blue and green to the state of red, thereby aligning the balance between
the colors and getting a more or less beautiful picture, that is, one that matches the colors,
but at the same time we have already lost about 18 20 percent of the color palette,
that is, our colors remained colored but lost in saturation, and so it goes on, that is,
we still go down 10 meters again, we lose red again, we put a filter, more precisely,
the filter is already on us and it again cuts us blue and green, leaving us only that amount
of red which will correspond to these blues and greens, more precisely, blue and green
will correspond to the amount of red that is present at a given depth under given conditions
there is undoubtedly the second option, it is a little more complicated but more preferable
because you do not lose anything with this option, but you get a saturated image and
what with the correct colors that are available, you do not use you use white balance control
on your camera and use external light sources such as underwater lights in the next video
I will definitely tell you how to choose the right flashlight what characteristics of the
flashlight you should pay attention to which LEDs are better which are worse and why they
are worse and if many shot underwater then they noticed the color of their faces in this
case of mine, then the real face is pink and the color of the body, then when you start
shooting underwater, you often notice that people’s faces are gray or gray-blue, and
there will also be purple, which indicates that you have chosen the wrong one lantern
ok with you as always there will be albert thank you very much put likes subscribe to
the channel write in the comments which option you would like to use for yourself try to
shoot beautifully and good luck to you goodbye
