Waching daily Feb 4 2017

Today I'm gonna show you how to obtain a cinematic look by color grading your images

in Lightroom and we are starting right now.

Hey guys I'm Criss and you can find me on Twitter and Instagram @eyestocker.

If this is your first time here and you are interested in photo and video editing tutorials,

hit the subscribe button and that bell notification to make sure you don't miss anything.

Ok, so first of all, what is color grading?

According to Wikipedia "Color grading is the process of altering and enhancing the

color of a motion picture, video image, or still image".

So basically you add complementary colors into the shadows, midtones and the highlights of

your image.

Let's see how we can do this in Lightroom.

I opened up this very cool image with an athlete preparing to make a deadlift exercise.

When making a color grading try to adjust the photo to have a low contrast, because

this will give you a better control on the details.

And question of the day guys: when are you adjusting your contrast? before starting to

take photos or in post production?

Leave your comments below.

So I will start here by adjusting the temperature of this image, I'm trying to find a neutral

look for the white balance and I think that a negative 4 or 5 will be a good choice for

the moment.

Next I will try to bring back some details here in the windows area, so I'm pushing

the Highlights slider to the left.

I will move down to the Split toning Area now.

This is the place where I can add specific colors for the shadows and highlights.

But I will need to choose colors which are complementing each other.

I have a lot of r ed in my image, in the bricks and her skin.

The complementary colors could be Red with Green, Blue with Orange and so on, you can

check out this website called Adobe Color CC, I drop you a link in the description,

where you can choose here "Complementary Colors" and then… have some fun by choosing

the perfect tones for your image.

In my case, because I have a predominant Red color in the photo, I will use Red for the

shadows and a light Green for the highlights.

So let's get back into Lightroom now and choose that Greenish color.

It's not too dark… this is for the highlights.

And for the shadows I will choose a light red also.

If the saturation doesn't feel so right, you can adjust the sliders like I do now by

setting a new value because remember, you don't need to over due the color grading.

The final look should be very soft, very delicate.

I can also use this balance slider if I want to push this toning more to the green part

so I will set it to 20.

Let's choose some values in the Camera Calibration Tab.

I want to cool down the dark floor and the shadows so I'm gonna grab the Blue Primary

Hue slider, drag it to the left to .. let's say -40 or so and push the saturation to the maximum.

Keep in mind that these settings cannot be the same for your image, so you'll have

to deal with these values on your own and see what works for you.

Ok, I think it's time to crop my image.

If I want that film look I need to go at least with a 16:9 ratio, so I'm gonna choose the

crop tool and from the aspect ratio I'm gonna choose 16:9.

I'm gonna try to respect the rule of thirds and keep her face on this line, making sure

also to have a point of interest somewhere near this line, in my case the lifting bar.

I will add some contrast to the image, something like that.

And now I will come down to the Tone Curve and on the RGB channel, I create a point here

in the shadows area.

Then I start pushing this point upwards to create this very popular matte effect by crushing the blacks.

I think I can increase the exposure just a bit to a 0.5 for example.

So let's have a look at a before and after.

You can hit the backslash on the keyboard to switch between the before and after and you can also press

on this icon right here to have the before and after side by side.

This way you can see the huge difference between the original and the edited version.

It looks awesome!

I'm Criss, thanks for watching and catch you in the next one.

James Dark SEMA 2017 Interview - Can he get his truck to SEMA? - Duration: 3:35.

When I was 8 years old

My Dad passed away

and I remember alot of times where he'd be out in the garage

and then many years now where I am in a garage

he used to restore Shelby's

he'd have Shelby's all over the yard

as well as my Grandfather would help, he'd restored some Mercury's

but they were always a Ford family

we still have engines and car parts, bumpers, fenders and rims in the garage

and I enjoyed going out there and I guess that's where it all started

I remember after my Dad had passed, I spent a lot of time in North Carolina

with my Grandfather

and he had this old farm truck, it was a 70 Ford F100

long bed, unfortunately

but it was still a cool truck

and I think that's how I learned how to drive a stick

3 on the tree

and I really loved that, that old green truck

and when I was able to get my own vehicle

my first vehicle was a truck

it was a 92 Dodge Dakota

I love that truck

and til this day I still regret getting rid of it

when I turned 18

I decided I want to get the new body style Dakota

other than the one I had

so I went ahead and got it

upgraded to a 4-wheel drive, V8

and I did what every 18-year-old does

when they get some power

and 4-wheel-drive

they start driving over everything and through everything

and you break and few things here and there

and then you buy some parts

and you keep buying more parts

and then one day I started cleaning it

and that's where we are today

we are lifted on 37s

shaved and airbrushed

suicide hood, dump bed, full interior

and that's where the truck is now

and I've been a member I was a member of a club for a long time

and we went to a lot of events a lot of shows all throughout the Mid-Atlantic

and I had a lot of fun

it was a lot of fun with those people

and I really enjoyed my time

but there's one show I've never been to

that I always wanted to go to

and it's SEMA in Vegas

I never thought I was going to take a truck

that I bought when I was 18 years old and get it to SEMA

and it looks like 2017 is going to be the year

this build is going to be remaking the entire truck

from the ground up

and we are doing a

full baja chase vehicle conversion

wide bodied

with new wheels and tires

full custom wrap

full fabricated chase rack

roof rack

all new interior

and it should be a sight

it's going to be something really cool

and I'm going to be really proud of

I'm going to spend a long time working on this thing, a lot of nights a lot of weekends

I still have a family

I got kids

and a wife that understands this process

and we're going to make this happen

so SEMA 2017 here we come

Know Your Propaganda – 'Arguing from Ignorance' – What is it and where have we seen it - Duration: 11:01.

Know Your Propaganda � 'Arguing from Ignorance' � What is it and where have we seen it?

Have you ever heard the statement, �There's no such thing as monsters�?

What about, �It's impossible to travel through time�?

Many of us have heard these statements, either from our parents at bedtime while they are

trying to get us to go to sleep or from a closed-minded friend during conversations

about the unknown.

We've probably heard such statements lots of times, but what happens when we try to

prove them true?

You Don't Know what You Don't Know

When trying to prove any point, there are a number of things we may want to keep in

mind, but for now we'll just talk about one.

This is a fallacy called arguing from ignorance.

To put it simply, this is when a person makes a solid claim simply because the opposite

of the claim hasn't been proven.

When a person claims universal nonexistence of UFOs�for example�simply because they

don't know anyone who has seen one, they've just argued from ignorance.

This is completely contradictory to elementary logical.

Let's break this down a bit more.

Here is the website, Logically Fallacious.

Argument from Ignorance

(also known as: appeal to ignorance, absence of evidence, argument from personal astonishment,

argument from Incredulity)

Description: The assumption of a conclusion or fact based primarily on lack of evidence

to the contrary.

Usually best described by, �absence of evidence is not evidence of absence.�

Logical Form:X is true because you cannot prove that X is false.

X is false because you cannot prove that X is true.

Example #1:Although we have proven that the moon is not made of spare ribs, we have not

proven that its core cannot be filled with them; therefore, the moon�s core is filled

with spare ribs.

Explanation: There is an infinity of things we cannot prove -- the moon being filled with

spare ribs is one of them.

Now you might expect that any �reasonable� person would know that the moon can�t be

filled with spare ribs, but you would be expecting too much.

People make wild claims, and get away with them, simply on the fact that the converse

cannot otherwise be proven.

https://www.logicallyfallacious.com/tools/lp/Bo/LogicalFallacies/56/Argument_from_Ignorance

We may note that the argument from ignorance applies to both universal existence and nonexistence.

A positive statement such as the following applies: "You can't prove that Bigfoot doesn't

exist.

Therefore he does."

This is also an example of an appeal to ignorance.

In essence, we learn that the universe is full of countless possibilities, and that

making any universal claim based solely upon lack of evidence to the contrary is an irresponsible

choice for us to make.

Though such flawed claims may help a child go to sleep at night, or help shady politicians

manipulate their audience, these claims are largely useless to those of us who are responsible

and honest.

So we know now that we can't make universally negative claims that we can't prove, but what

if we did have proof?

Know Your Propaganda - "False Dilemma" - What is It?

Proof Positive

If you caught that the question above was a trick question, pat yourself on the back

and then listen to this.

The fact is that in the tangible world, you cannot have negative proof.

Now what does this mean?

It means that it is only possible for proof to add to our knowledge base.

Proof can't take our knowledge away.

This adds to the above principle that it is logically impossible to prove universal nonexistence

in the physical universe.

So when we say, �There is no such thing as monsters,� this is a flawed and irresponsible

statement because it's impossible to prove.

Again, it might work in putting a child to sleep (and often puts us to sleep as adults),

but there is no way to prove it.

Let's get some more definition for this concept of positive proof.

We turn to Quora.com for an explanation.

In this excerpt, the author has just finished explaining that it is quite possible to prove

negative existence in abstract contexts such as in math.

The physical world, however, is a different story.

Things become difficult outside of math and inside science.

Here the statement "you cannot prove a negative" applies because we are now dealing with real

world observable evidence.

All evidence is unconditional, in that once we see it, we have it, and it is true.

Evidence is falsifiable, but never false.

There is no negative evidence, and this is the underlying positivism of nature.

Evidence also only adds up.

It never multiplies or divides or subtracts.

It only adds information, that either backs what you were hoping it backs, or something

else.

But it always backs something.

Of course, what it backs is open to interpretation, manipulation, and error, but these are all

of our trivial problems.

Nature is incapable of lying, and can never contradict itself.

We may not always understand what it is saying, but it only speaks truth.

Given the fundamental tenet of addition that you cannot add positives and get a negative,

we can bring it all together and get this:

a) evidence is unconditionally positive b) evidence only adds

c) positives never make a negative

=> Evidence only has positive inference.

And that is why you cannot prove a negative with evidence in science.

https://www.quora.com/Can-one-prove-that-something-doesnt-exist

So we see that evidence is only additive by definition, and again, it is logically impossible

to submit any scientific proof that takes away our knowledge even if that evidence is

contrary to rest of our evidence.

No amount of documentation, evidence or testimony can prove a universal point negative.

However, this does not apply when referring to the existence of say an object in the room

we are standing in or in a specific area.

Thought Process

It is very possible to prove whether there is or is not a chair in the far corner.

I can also prove that I don't have food stuck to my face.

I think you get the idea.

If there is any limitation of area specified in the statement, then the statement can be

proven.

This is the logical basis by which legal cases are determined.

�Was the crime committed in this place, by this person, and with this weapon?� This,

we can disprove.

Eyes Peeled

There are lots of people who attempt to claim universal nonexistence in order to manipulate

their audience.

Pseudoskeptics, for example, pretend to have more scientific knowledge than they actually

do.

Many times, these people will claim fictitious scientific superiority over everyone who disagrees

with them.

They attempt to control the thoughts and ideas of those around them by deliberately arguing

from ignorance.

You will hear people claiming that some concept is impossible.

They will say that there is no such thing as UFOs or that free energy is impossible

simply because they have never seen it.

In fact many of these people actually believe in some of the concepts they argue against.

However, they refuse to admit the possibilities either due to their overgrown ego or their

fear of change.

(Usually, it's both.)

Corporate Media Admits to Publishing Viral Fake News After Independent Media Busted Them

Pseudoskeptic are often hired by corporate entities, and have the specific task of discouraging

people from thinking outside the current paradigm.

This is done primarily because the current paradigm has been obsolete for a very long

time, and the only reason we are still using century old technology is because our ignorance

is profitable to numerous industries.

Consequently, we are prevented from having cleaner, safer, and more equitable technology

in our everyday lives.

The world of pseudoskepticism is one of numerous places where we see the fallacy of arguing

from ignorance.

This fallacy typically takes on a whole new meaning when actual professionals attempt

to use it.

I will say this: If ever you see a trained scientist, doctor, detective, lawyer, a politician,

or any scientifically trained professional using fallacies such as these, be on alert.

There is usually a specific reason for this.

In all valid training for scientific professions, the knowledge and skill of logical proof is

foundational.

One cannot become a scientist, a doctor, a forensic specialist, or hold any other proof-based

profession without having extensive knowledge of how to prove a point.

So if any for these individuals to casually use logical fallacies either directly equates

to negligence or dishonesty.

The NDAA Legalizes the Use of Propaganda on United States Citizens - Commentary and Links,

Plus an Interview with Dr. Udo Ulfkotte

It is one thing to misspeak once or twice, but if say, your dentist or legal adviser

regularly uses these fallacies, not only should you find a new one, but they should have their

license to practice, revoked.

Either their fallacies are accidental, or they are deliberate.

(It is debatable whether or not one can have half of an accident, but in this case, I would

say not.)

The ability to prove a valid point is a basic necessity in any aspect of the reliable professional

world.

Any scientifically trained person or public figure who has the ability to maintain their

logical and ethical integrity is typically a good source of information.

For those who do not, it may be time to trade up.
