Telephoto lenses can be fixed or variable, and range between 70-200mm. They have a long focal length, so they let little light reach the focal plane, producing images that magnify a narrow portion of the scene. This makes them ideal for shooting subjects that you have to be far away from for safety or practical reasons, such as during explosions, fires, heavy-equipment use or when you just can't get there fast enough. Remember, these lenses misrepresent the proximity of your subject to background and foreground objects, making things appear closer than they are, so use them with caution.

12c. Hand Length- Measure from the wrist to the the base of the hand to the tip of the middle finger or to the top of the longest finger.

12a. Hand Circumference- Measure around the palm of your dominate hand, which is usually just below the knuckles. Exclude the thumb.

10. Head Circumference- For an accurate head measure, place a tape measure across the forehead and measure around the full circumference of the head. Keep the tape snug for accurate results.

11. Sock Measurements- The following measurements are for crew-style or dress socks, which usually come several inches above the ankle and below the calf.

There are two types of lenses in photography and videography: variable focal length and fixed focal length. When you carry a variable focal length lens, you will be able to produce a variety of shots. If you are carrying fixed focal length lenses, you will need to change your lens to capture wide, medium and close-up shots.

Both types of lenses give you the opportunity to master a technique known as a rack focus. Rack focus is the recorded shift of focus from one object to another.

Focal length

Both the FIT and LENGTH charts are simply guidelines. For individual body differences, changes can be made in body and sleeve lengths when appropriate. However, consideration must be given to the project pattern. Certain sizing changes may alter the appearance of a garment.

Focaldistance vsfocal length

If you choose fixed focal length lenses (FFL), you will need a number of lenses with fixed focal lengths if you will be recording images with varying depths of field. A fixed focal length lens - often referred to as a prime lens - has only one focal length, which cannot be changed. Fixed focal length lenses usually provide more clarity because of less glass and come with a faster aperture. For example, the fastest aperture when shooting at 85mm on a 24-105mm lens is usually f/4-f/5.6. Fixed lenses often provide faster apertures such as f/1.2-f/1.8, which creates eye-catching critical focus on your subject, which is great for studio interviews. Unlike VFL lenses, weight does not shift as much in FFL. This makes FFL the better option to use with gimbals.

When sizing sweaters, the fit is based on actual chest/bust measurements, plus ease (additional inches or centimeters), sometimes referred to as "negative ease" (less than the actual bust/chest measurement) or "positive ease" (more than the actual bust/chest measurement). The chart entitled “Bust/Chest Fit and Ease Chart” recommends the amount of ease to add or subtract to bust/chest measurements if you prefer a close-fitting garment, an oversized garment, or something in-between.

FOV tofocal length

A variable focal length lens (VFL), more commonly called a zoom lens, can change focal lengths within a certain range, thereby changing the magnifying power of the lens by zooming in or out. From a stationary position, if the lens has a short focal length, the object being documented will be smaller and more of the background will be shown. From that same position, a lens with a longer focal length will make the subject larger, eliminate some of the background and exaggerate the depth of field. As an example, a 100mm lens will make the subject twice as large and show less of the background than the image produced by a 50mm lens. This effect is known as lens compression. The ability to zoom in and out with VFL lenses makes these lenses more versatile for uncontrolled action and allows you to pack less for the field.

11b. Sock Height- To determine the height of the sock, measure from where you start to turn for the heel shaping to the top of the sock.

Wide-angle lenses can be fixed or variable and range between 15-35mm. They have a short focal length, so they show a large portion of a scene. They're perfect for documenting scenes in cramped spaces such as on an aircraft carrier or when there is a lot of movement, like on a helicopter. Remember though, these lenses distort the image and perspective, particularly as the field of view increases.

11c. Total Foot Length- To measure the total length of your foot, place a ruler or tape measure on the floor. Position the back of your heel at the beginning of the tape and the measure to your longest toe.

To ensure that a finished garment will fit properly, it is important to take the following body measurements, so that you can determine what size you should make. It is always better to have someone else do the measuring. If that is not an option, you can measure a garment that fits you the way you want, and use these measurements as a guide. Most crochet and knitting pattern instructions will provide general sizing information, such as the chest or bust measurements of a completed garment. Many patterns also include detailed schematics or line drawings. These drawings show specific garment measurements(bust/chest, neckline, back, waist, sleeve length, etc.) in all the different pattern sizes. (See more about Schematics p. 25) To insure proper fit, always review all of the sizing information provided in a pattern before you begin.
