In this clip, you'll see how to construct a pass filter, commonly called a high-gain or band-pass filter. To do this, you'll use the HSV channels to identify what to do, the RGB curve to make an inversion mask, or negative, so that the image is added to itself, thus evening out the contrast and making a very flat image. This image can then be tiled and used as a seamless texture. Whether you're new to the Blender Foundation's popular 3D modeling program or a seasoned graphic artist just inter...
In this tutorial, you'll see how to use the Scale Node in the Blender Compositor to manipulate an image.

Exponent of a number is nothing but the number multiplied to it self the exponent number of times. So five squared it equal to five multiplied to it self. Now when an exponential number is divided with another such number the result is the number raised to the different of the exponents. That is the ratio of x raised by a to x raised by b is x raised to (a-b). Similarly if we multiply a exponential number with other such number, the result is equal to that number raised to the sum of exponent...
When you are given a point through which a line passes and the slope of that line, you can calculate the equation of that line. The general equation to solve this kind of equations is called as point-slope form. The point slope of a line passing through (a, b) with slope of m is (y - b) = m * (x - a). Now substituting the values in the above equation you can obtain the equation of the line in terms of x and y. In case you are given with two points first find the slope of the line which is the...

In this video the instructor shows how to find the slope of a line given two points that like on the line. Slope of a line is the measure of the steepness of the line compared to the angle made by the line with the x-axes. A line with positive slope slants forwards and a line with a negative slope slants backwards and a line parallel to x axes has zero slope. So if you are given two points (x1, y1) and (x2, y2), the slope of the line passing through those two points is equal to m = (y2 - y1)/...

In this video the instructor shows how to find the equation of the line given its slope and a point that lies on it. If the slope of the line is m and the point that lies on it is (x,y) then you can find the equation of the line by substituting the values in the slope-intercept form of an equation which is y = mx + b. Now substitute the values in the above equation and solve it for the value if the y-intercept y. Now you have the slope m and y intercept b. Substitute these values in the gener...
In this video the instructor shows how to derive a general equation for a line in Point-Slope form. The slope of an equation is the ratio of difference of y coordinates to the difference of x coordinates. In other words, slope is the change of y up on change of x. So you have the basic slope equation m = (y2 - y1)/(x2 - x1). When you have fractions you can simplify them by multiplying the denominator to the numerator on both sides. So multiply the equation by (x2-x1) on both sides. This gives...
In this video the instructor shows how to write a linear equation. If you need to find the equation of a line that passes through the two given points then you need to find the linear equation of that line. The first step is to find the slope of the line that passes through these points. The slope can be calculated by finding the ratio of the difference of y coordinates to the difference of the x coordinates i.e. the change in y up on the change in x. Now substitute the value of slope and any...
This video shows us the method to find the percent increase or decrease in a quantity. This can be done in 30 seconds. The formula states that the percentage increase or decrease is equal to the product of the ratio of amount (increase or decrease) and the original amount and 100. This is explained by two examples. In the first example the amount of increase of the price of groceries is found by taking the difference of the new price and the old price. This is divided by the original price an...
Do you have a SLR and yet you feel that you are missing out on some features? Let's check out the back button focus. When you press the shutter button half way, it moves the focus to the back button.

After changing the blend mode to multiply and adjusting the brightness, you then change the opacity and you'll have the "wrinkled paper" effect you're looking fo...
This is how you can vector an eye in Adobe Illustrator. You will first want to upload your photo to PhotoShop and then increase the contrast to highlight your picture better. Increasing the highlights is not a necessary step however. This is an intermediate process but the end result with be a cartoon looking eye on a real person. If you used this effect for the whole picture it would look very neat like your own cartoon character! If you only subtly vector the eye then you still have an edit...
In this tutorial the author shows an easy and simple way of subtracting fractions with uncommon denominators. He says that to subtract fraction with uncommon denominator, we need to make their denominators equivalent first and after making the denominators equal, you need to increase the numerators proportionally to maintain the original ratio of the fraction. Now as the denominators are same, we can directly subtract the numerators arriving at a new fraction. He further shows how to deduce t...

Finding horizontal asymptotes is very easy! Not all rational functions have horizontal asymptotes. the function must satisfy one of two conditions dependent upon the degree (highest exponent) of the numerator and denominator. If the degree of the numerator is equal to the degree of the denominator, then the horizontal asymptote is y= the ratio of the leading coefficients. If the degree of the denominator is greater than the degree of the numerator then y= 0. If the degree of the denominator i...
This video teaches the viewer how to make miniature Valentine swirl truffles. The most important thing to be kept in mind is that the two colors of clay being used should be of contrasting shades.
