Hoya Variable Density II Variable density camera filter 6.2 cm
HOYA Variable Density II is a density adjustable filter with an ND range from 1.5 to 9 f-stops (ND3-400).The difference with the previous HOYA Variable Density filter is the newly designed rotatable frame with convenient knob. allowing for better operation.Why variable density filters are importantVariable density filters are widely used because they can replace a set of solid ND filters by providing a range density that can be adjusted according to the desired exposure settings.In still shooting. variable density filters lower the shutter speed according to the photographer’s intentions when the shutter speed cannot be lowed due to camera limits.Variable density filters can also increase the amount of boke when shooting in the over-lit conditions. thus. preventing the image from overexposure.In video shooting. it is fundamental to keep the shutter speed fitting the frame rate setting. That is. to keep it equal to double the frame rate for optimal results. This is because. unlike still photography. an excessively fast shutter speed may create a jarring effect and produce afterimages that will not look good in the final video.As you can see from the image below. unlike still image. a video clip is made of a sequence of still images. With low shutter speed. each still image will blur but will look smooth in the video sequence. On the contrary. a higher shutter speed will capture the object solid and sharp. but once in a video sequence all objects will appear separated. creating jarring and unnatural looking motion.By using variable density filters. the shutter speed can be adjusted to the proper value to get that natural and smooth looking motion requested in video footages. as shown in the image below.Highlighted featuresHOYA Variable Density II incorporates exclusive rotatable frame construction that consists of fixed frame and rotatable frame. The rotatable frame gets wider compared to fixed frame size in order to minimize the risk of vignetting when used on wide angle lenses.Lens cap compatibilityDue to the specific structure of the filter frame HOYA Variable Density II can take one size bigger lens cap than the size of the filter itself. For example. 77mm HOYA Variable Density II can take 82mm lens cap. as shown on the image below.For longer exposuresWithout changing the aperture. the HOYA Variable Density II provides the freedom to change the shutter speed according the effect desired. Effective for motion blurring effects like waterfalls. cars or blurred panning movement to make the subject stand out from the background.For wider aperturesAllows wider apertures in over-lit conditions be used to decrease depth-of-field. literally focusing more attention on the subject.Preventing overexposureEven with a shutter speed of 1/8000 seconds. a large aperture of f/1.4 or f/1.2 can cause overexposure. With the HOYA Variable Density II filter. overexposure issues can be avoided by adjusting the light intake.For shooting video in cinematic lookVariable Density filter is a must-have item for video bloggers and professional video content creators. Allow cine/video cameras to set the appropriate exposures in a bright lighting conditions to achieve cinematic look.

Hoya 52MM VARIABLE DENSITY II
The New HOYA Variable Density II is an upgrade of the original Variable Density filter and features a newly designed rotatable frame with convenient knob allowing for better operation.These filters provide a convenient way adjust exposure control by varying the amount of light entering the camera by 1.5 to 9-stops (equivalent to NDx3-400 or 0.45-2.7 density for Cine). The precision double-ring design allows the outer ring to rotate controlling the amount of neutral density anywhere within the 1.5 to 9-stop range. The thin double-ring design also reduces the likelihood of vignetting with wide-angle lenses. These versatile filters allow for many special effects such as being able to control depth of field by using a wider aperture as well as create or control motion blur by being able to choose slow shutter speeds for perfect blurring.Lens Cap CompatibilityHoya Variable Density II filters require a lens cap one size larger than the size of the filter itself. For example the 77mm Hoya Variable Density II Filter requires an 82mm lens cap.Features• Reduces shutter speed for motion blurring effects (water people vehicles etc.)• Allows wider apertures to be used to decrease depth-of-field• Special removeable knob for convenient density adjustment• Convenient density scale• Allows video/cine cameras with limited shutter-speed range to film in bright lighting conditions• For best results with slow shutter speeds always use a tripod!• Available in sizes from 52mm to 82mm diameter

What is a variable and non-variable quantity?
A variable quantity is a quantity that can change or vary, such as the temperature, time, or the price of a product. These quantities can take on different values and are often represented by symbols or letters in mathematical equations. On the other hand, a non-variable quantity is a quantity that remains constant and does not change, such as the speed of light or the number of sides in a triangle. Non-variable quantities are fixed and do not depend on any other factors.

What is the difference between software development and programming?
Software development is a broader term that encompasses the entire process of creating software, including planning, designing, testing, and maintaining software applications. Programming, on the other hand, refers specifically to the act of writing code to instruct a computer to perform certain tasks. While programming is a key component of software development, software development involves a more comprehensive approach that includes various stages beyond just writing code.

What is the difference between variable definition and variable initialization?
Variable definition is the process of declaring a variable and specifying its data type, such as int, float, or string. This tells the compiler or interpreter that a variable with a certain name and data type will be used in the program. Variable initialization, on the other hand, is the process of assigning a value to the variable for the first time. This can happen at the same time as the variable is defined, or at a later point in the program. Initialization gives the variable a specific value to work with, while definition simply sets up the variable's characteristics.
-
How can one express a variable in terms of another variable?
One can express a variable in terms of another variable by manipulating equations or formulas to isolate the desired variable on one side of the equation. This can involve performing algebraic operations such as addition, subtraction, multiplication, or division to rearrange the equation. By doing so, the variable of interest can be written in terms of the other variable, allowing for a clearer understanding of the relationship between the two variables.
-
How can I store a JavaScript variable in a PHP variable?
To store a JavaScript variable in a PHP variable, you can use AJAX to send the JavaScript variable to a PHP script on the server. The PHP script can then receive the variable using $_POST or $_GET superglobals and store it in a PHP variable. This way, you can pass data between JavaScript and PHP seamlessly.
-
How can I output a batch variable in a variable name?
You can output a batch variable in a variable name by using the delayed expansion feature in batch scripting. To do this, you need to enable delayed expansion by using the "setlocal enabledelayedexpansion" command at the beginning of your script. Then, you can use the "!" symbol instead of "%" to access the value of a variable inside another variable. For example, if you have a variable named "var1" and you want to output its value in a variable named "var2", you can use the syntax "!var1!" to achieve this.
