How To: Operate a steadicam

A steadicam can mean the difference between a professional and steady wide shot of Victorian era London or a wobbly, user-generated content-esque portrayal of some old lamps and streets. Having control over how your camera moves is so vital to good film production.

How To: Use a wide or telephoto lens for portrait photography

Mark Wallace shows us how to use a wide lens for portrait photography. A longer lens minimizes distortion in your picture and it maximizes what type of view you can see, so you can see more of the thing you are taking a picture of and less of the background. These lenses help keep the picture clean and uncluttered. You can see the difference between a wide and short angle lens by taking pictures with them and looking at the differences between them. There is also a zoom available, which makes...

How To: Create ghosts in Blender with difference keying

Use nodes to compute the difference between two images, usually a matte or background shot and then the same shot with actors in the set. This technique was used in the film "Death Becomes Her" starring Meryl Streep, Goldie Hawn, and Bruce Willis. Use this technique to create ghosts, glass people, or to uncover watermarks and prove video ownership. Whether you're new to the Blender Foundation's popular 3D modeling program or a seasoned graphic artist just interested in better acquainting your...

How To: Generate random numbers (with decimals) in Excel

This video shows you how to generate random numbers with decimals in Microsoft Excel.When generating random numbers you must have a lower and upper limit, so that your number will be generated between the two limits. For a number without decimals, you only have to use the "=randbetween" function. If you want to use decimals, you will have to use a different but similar function. Start by typing "=rand()". Next, you multiply this by the difference between the limits and add the lower limit. Fo...

How To: Use direct and indirect reining

Rick Gore explains the differences between direct reining and indirect reining to have better control over the horse and have him go where you desire. Direct reining, also referred as plow reining, is when pressure is applied directly to the horse by pulling the rein. Apply as much pressure as you want to have the horse turn the way you want. Indirect reining on the other hand, is without pressure, laying the rein on the horses' neck to give him an indirect cue to go a certain way, instead of...

How To: Know the differences in quinoa

In this tutorial, we learn to know the differences in quinoa. Quinoa is a complete protein that's very mineral rich. There is a tan and red variety, both are delicious. This is an ancient South American grain that is gluten free for the wheat intolerant. When prepping this, you will first need to rinse it off thoroughly. Cooked quinoa can be mixed with toasted sunflower seeds, lemon juice, sea salt, and olive oil for a great taste that is full with nutrients. It's a great replacement for rice...

How To: Grasp the differences of census, study, & sample survey

In this tutorial, we learn how to know the difference: census, study, & sample survey. The census is when everyone's opinion is needed. An example is when you will see census studies happen throughout the year from the government seeing how many people live in one household. A study is when you only need the opinion of experts. This can be when companies are releasing a new product and need the opinions of doctors or dentists about it. A sample survey is when a few people's opinions are enoug...

How To: Demonstrate the difference between land & sea ice

In this tutorial, we learn how to demonstrate the difference between land & sea ice. First, fill up two large aquariums with water, then add in a glacier to one aquarium and an iceberg in the other. This will see how the water level changes based on the melted of each different ice item. Draw a line at the water line where it started at, then when the ice melts, check the water levels. When finished, see what the water levels have ended up at. Now you will be able to show this to your student...

How To: Use colons and semicolons

In this tutorial, we learn how to use colons and semicolons. You will use a colon when the second sentence is explaining a 'why' of the first sentence. You will use a semicolon when the second sentence is adding more to the first sentence, not explaining it. You can also use a colon when you are writing a long list and the sentence can't stand alone. Use a semicolon to separate two sentences that can stand independently. Knowing the difference between when to use these punctuations can mean t...

How To: Find the equation of a line in point-slope form

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...

How To: Use number patterns in math

In this video the instructor shows how to identify patterns in numbers, figures, letters. When given a pattern like 1, 2, 4, 7 try to find the change in each of the successive numbers in the pattern. If you observe carefully you will notice that the difference of the second and first number is one. Similarly the difference of the third and second number is two and this pattern keeps repeating. So this pattern is generated by taking 1 and adding 1 to it. To the next number add 2 to get the thi...

How To: Find the slope of a line given 2 points

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)/...

How To: Write a sum/difference of logarithms as a logarithm

To write the sum or difference of logarithms as a single logarithm, you will need to learn a few rules. The rules are ln AB = ln A + ln B. This is the addition rule. The multiplication rule of logarithm states that ln A/b = ln A - ln B. The third rule of logarithms that deals with exponents states that ln (M power r) = r * ln M. Using these three rules you can simplify any expression that involves logarithms to arrive at a single logarithm. The instructor shows how to apply these rules to a f...

How To: Find the equation of a line

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...
