A common problem when shooting in low-light situations is that even if you open your lens to its lowest f-stop number, you're left with an image that's far too dark. One obvious remedy is to add more light. But what if you don't have more lights available to you? That's where the gain increase switch comes in. This free video cinematographer's guide will show you how to use digital gain settings to amplify available light to get better shots in less-than-ideal environments.

Photography is a fast growing hobby with the relative drop in prices of high grade equipment. The use of different filters in photography is a very common thing, and different filters have very different uses. The neutral density (ND) filter reduces the amount of light reaching the film or sensor.

Fractions are numbers of the form a/b, where a and b are integers. Fractions are also called as ratios. Fractions are further divided into proper fractions and improper fractions. Proper fractions are those where the numerator is less than the denominator and improper fractions are those where the numerator is greater than the denominator. As fractions are ratios a fraction can have many equivalent forms. Multiplying the numerator and denominator of a fraction with a same number gives a fract...

In this video the instructor shows how to factor a polynomial. A polynomial having three terms is called as trinomial. Now if you factor it you will obtain two binomials whose product will be the original polynomial. Before factoring a polynomial you need to find out if the polynomial has a GCF. Look out for the common variables in all the three terms and pull them out which is the GCF of the polynomial. This simplifies the original equation to a polynomial which is of lower degree. Now facto...
In this video a question is asked by a viewer. What is perfect pitch and what is relative pitch? Perfect pitch is something that is developed at a young age and comes easily.

Now finally try to get the variables on one side and numerical terms on the other side of the equation and finally solve for the u...
In this video the instructor shows how to multiply and write rational expressions in lowest terms. The fist thing you need to do is cancel out the common factors in the numerator and the denominator.
