Definition of a Tripod
A Tripod is a device used to position, support, and stabilize a camera. A tripod is a three-legged stand that provides stable support for a camera giving sharper images while allowing smooth panning and tilting, thus eliminating unwanted camera shake. Tripods usually include an adjustable movable “head” that the camcorder is affixed to. They are often used with slow shutter speeds and telephoto lenses. The height of the camera and of the individual legs can usually be adjusted.

Advantages in using a tripod
1) Eliminating Camera Shake
.
Cameras attached to a tripod produce razor-sharp photos. Your hand held camera can be focused perfectly and you still can end up with a fuzzy picture. Do not confuse the blurriness produced by camera shake with a photo that is out of focus.

2) Using Telephoto lenses.
A tripod should be used when the shutter speed is faster than focal length of your lens. For example, a shutter speed of 1/500 second using a 500 mm lens. More precisely when your shutter speed is less than 1 divided by the focal length of your lens.
3) Using Slow shutter speeds.
Use a Tripod when the shutter speed is less than 1/60 of a second or taking photos at night. Many professional use their tripods for every photo they take.

3) Using unusual camera angles.
With a tripod you can put your camera into places that would otherwise be inconvenient. Such as very high or very low, or aimed up or down.

4) Creating a studio environment.
The tripod frees you from holding the camera so you can concentrate on the other aspects of your shoot. Such as lighting of your subjects, positioning of your subject etc.

Tripod Parts
Including legs, column, head, camera attachment plate and Dolly.
1) Attachment plate.
The attachment plate connects the tripod head to your camera. There are two types of plates, fixed and detachable also called quick-release. A fixed plate makes you screw and unscrew your camera to the tripod every time you use it. A quick-release plate allows you to connect and disconnect you camera in one simple motion. It has two parts, one half attaches with a screw to the head of the tripod and other half attaches with a screw to your camera. This is much easier to use than screwing and unscrewing your camera to the tripod every time you use it.

2) Head.
The head of a tripod attaches above the column (on some models, also to the bottom of the column). The head is the connection between the column and the camera attachment plate. The three main varieties are pan-tilt head, ball-head and geared-head. Pan-tilt heads are usually seen on video camera tripods and can pan right and left, and can tilt up and down. A ball head works like your head and neck, it can tilt and rotate in any direction. A ball head is good for action photography, it can give you a wide range of motion very quickly. A geared-head is also a pan tilt head but is more precise in positioning and aiming your camera. It is also slower in making large movements, it may take 20 turns of the knob to move through 90 degrees. Geared heads have adjustable knobs that offer precise movement in two or more directions. The key points of a head are, how smoothly it moves, how much weight it can support, and whether it has a quick release plate.

3) Column.
The center piece attached to the legs that can be raised or lowered with a crank to obtain the correct camera height. Once your camera is in position use the locking knob to secure the column.

4) Legs.
When the tripod is closed, the legs are folded together so the tripod is compact and easy to transport. When opening some tripods the legs move together, on other tripods the legs move independently. The legs will usually lock in any position.

5) Tripod Dolly.
A triangle or "Y" shaped bracket, with smooth rolling wheels, that supports and moves a tripod. A dolly can be used to help you follow a moving subject. Most dollies have locking wheels that allows you to use it in a stable mode.

Choosing the right tripod
Match the weight of your camera equipment with the load capacity of the tripod. Tripods have different maximum and minimum working heights, be sure to purchase one that meets your needs. You must choose between a pan-tilt or a ball-head, and a fixed plate or a quick-release plate. Use lighter weight tripods for nature and hiking photos, they are typically more expensive. Studio tripods can be made of heavier and less expensive materials.

Starved Electrolyte / Lead Acid Battery Information

How long they will last and how to prolong longevity:
Our batteries are rated to give 200 to 300 uses when they are fully drained (discharged to 9 volts) each use. When using with lights always remove battery when light has dimmed to yellow. Letting the light drain the battery under 9 volts will shorten the battery's life. If the battery is only used for 50% rated capacity up to 500 uses are possible. In the same way using only 30% capacity can result in up to 1,000 uses. Remember, there is no such thing as memory effect on these cells. Only use them for the time needed - after you're finished recharge them fully and then store away till next use.

Proper charging, care and maintenance:
It is always best to recharge a fully discharged battery as soon as possible (usually within 24 hours). Uncharged batteries will go bad if you wait too long before recharging. A partially discharged battery does not need charging immediately, but if you are going to store it away do so after charging it to full capacity. These batteries (when 100% charged) can be stored up to six months- after which a topping charge is recommended. Always store the battery in a cool, dry location .

Do not overcharge or undercharge batteries:
Constant over- or under- charging will shorten battery life.

We offer two types of chargers:
The first is an inexpensive taper charger that provides overnight charging. They work great but it is necessary to monitor the battery and disconnect the charger when done. Whenever a battery has been drained only partially, the charge times must be adjusted. You must pay attention to how much the battery has been drained. An example of this would be if you had a battery that powers a light for 60 minutes, but you only use it for 30 minutes - or 50% of it's capacity. If it takes 12 hours to recharge it fully, you would only recharge it 50% of the 12 hours , which yields a 6 hour recharge time.
The second type of charger we offer is an automatic shut off charger. Automatic chargers represent the best way to recharge and are fault-free. For our 12 volt batteries we offer two models: The ATM-PRB is a 1 amp overnight charger. The BCQ-12 is a 2 amp quick charger. With the BCQ-12 you can charge an MM-7 in 3 to 4 hours and a PRB-24 in only 12 hours.

How automatic chargers work:
Just plug it in and a red LED tells you the unit is charging. When the batteries reach a predetermined voltage the digital control Circuit cuts off the charge and the red LED goes off. Once this happens the batteries voltage will float downward. If the voltage drops below a certain level the charger powers up again and the red LED turns back on. A blinking red LED is not uncommon at the end of charge. If the red LED is off for at least ten seconds between blinks then you are fully charged - and at that time, you can remove the battery and store it away until next usage. Any auto charger should be removed after 72 hours.

Nickel Metal Hydride General Information
NMH batteries are rated to give 500 to 1,000 cycles in normal use. These batteries can be stored either discharged or charged. If stored fully charged they will self discharge over time. However, storing the batteries in a cool, dry place (refrigerator) will slow down the self-discharge process. It is best to use these batteries at least once every 6 to 9 months. Otherwise, the internal organic materials inside the battery will dry out and the battery's performance will deteriorate. For proper care and maintenance, do not overcharge or undercharge batteries. Constant over or undercharging will shorten battery life. For charging purposes we supply a simple low wattage taper charger. These inexpensive taper chargers provide a slow overnight charge that will maximize your battery's life span. They are very reliable but it is necessary to monitor the battery and disconnect the charger when done. We recommend the use of an inexpensive lamp timer. The timer can be used to turn off the power when the proper charge time has been reached. All brand new battery packs require 3 to 5 charge/discharge cycles to achieve the rated run times.

Top 10 list of battery facts.
1. Get a backup battery. With two or more batteries, you can charge one while the other is being used, and when one dies you have another to replace it.
2. Lead acid (gel cells) are great for occasional use, once a week or less. Gel cells are inexpensive, and retain their charge for long periods of time. Gel cells must be recharge after each use or they will chemically degrade and have a shorter life.
3. NiCad batteries are good for frequent and-or continuous use. They can be recharge up to 1000 times. Some can be "quick" charged in about 2 hours. They perform poorly when cold or hot and should be handled gently.
4. Recharge your NiCad batteries the day before you will use them. NiCads lose about 2% of their charge each day they sit on a shelf.
5. NiCad memory may become a problem. NiCad memory can occur when you have used the battery for a short period of time and then recharged it, used it again for a short time, then recharged it, and repeated this process a number of times. Eventually the battery "forgets" its original capacity (perhaps 30 minutes), and now, only operates your camera for a short period of time (perhaps 10 minutes). You may reduce the memory effect by "exercising" them with several cycles of deep discharging and recharging.
6. Invest in a "smart" charger if you use lots of batteries, they will make less mistakes than you will.
7. Rotate your batteries to insure equal use.
8. Lithium batteries recharge quickly and have no memory problems, but they are more expensive.
9. If your gear gets wet, especially in salt water, remove the batteries as fast as you can.
10. Power your lights and camera on separate batteries, they will last longer and will not interact.
