DC jvc bn-vf714u charger when using the card, including myself, many people will aim to press the shutter, few people to pay attention to technical details of this process. Yes, this is in itself a proper use of the card by way of DC. However, if your hand is a digital SLR, this camera method was not very "professional," not said no, but too much overkill. I think you do not want you to spend a higher price even bought 5,000 digital SLR can only play 40% of the skill, right?

So, when your hands get a digital SLR, I think you need to understand some basic concepts related to photography and terminology.

First is the aperture (Aperture). I think maybe most people feel this way: If you see a digital camera's lens aperture is large, will feel that this product professional enough, enough quality. In fact, this statement reflected in the term, that is the aperture. Note that the parameters of the lens aperture are, rather than digital SLR. However, when taking pictures with a digital SLR, the choice of aperture size is ultimately implemented in the lens. Therefore, we can come to the right through the lens aperture has an intuitive understanding.

In general, the same focal lengths, the lens aperture greater the greater the lens aperture, while the amount of light through the lens the greater. What light through large benefits?jvc bn-v20u battery

One is to have more light in imaging through the lens, so when shooting in dim light to take advantage of available light to shoot without flash.

Second, the larger the lens aperture help capture some photos of shallow depth of field - that is the focus of the kind of people clearly, but the bokeh photos. Remember I said said "you need a large aperture lens can be arbitrarily taken portrait bokeh," this is the case, right?jvc bn-v712u battery

Third, the lens aperture is an important measure of quality. In addition to the above two advantages, large aperture lenses are generally used better materials. For example, various non-spherical lens and ultra-low dispersion glass, etc., can make images more clear, sharp, and for a variety of aberrations.

Of course, the gains will lose, large aperture lens by a number of negative factors: for example, larger, heavier weight, convenient to carry; of course, is that prices are more expensive. Large aperture lens can easily break through the 5-digit prices, and even more expensive than the digital SLR itself.

In photography, the aperture size determined by F values. F = lens focal length / maximum diameter of light. Can usually see F2.8, F4.0, F5.6, F8.0, F11 and so on. Do not accustomed to think that the larger the number the greater the aperture. In fact in this equation, the light hole diameter is the denominator, so the greater the light hole, F is smaller. So this sort should be the size of the aperture: F2.8> F4.0> F5.6> F8.0> F11 ... ... and so on.

Another note is that the lens aperture is not constant, but can change (specifically, the article with pictures can be seen.) We are talking about is the maximum aperture the lens aperture, and is not to say that the size of fixed costs. Like I have a 500 horsepower sports car, usually not necessarily better than 200-horsepower car faster, I might just keep the engine low speed gentle cruising, but when needed, my car was definitely the outbreak greater energy. Say, understand?jvc bn-v812u battery

Short answer:

1, JVC BN-VF815 Camcorder Battery constant aperture lens and fixed iris lens is different, the former refers to a zoom lens, the zoom process, its maximum aperture, or set the aperture and the current remain the same lens, which means that only a lens aperture size, which kinds of lenses are common in the past, but now almost impossible see. Heritage ah.

2, constant aperture lens, a common principle is that the location of the camera lens aperture film began, to the lens bottom of the last lens, the location of all the lens when the lens zoom, and focal plane distance remain constant. The general non-constant aperture lens, the position of the aperture when the zoom will be running around  JVC BN-VF714 Camcorder Battery

But not all such lenses, the second principle is that a typical 4 4 zoom lens, the first film and the fourth lenses to form a convex lens in the normal sense, or a fixed focus lens, while at a concave lens is inserted between two lenses to change the virtual image distance in order to achieve the zoom, but the zoom will affect many things, so adding the fourth lenses, this move will lead to 2,3-lens aperture size and inclination of their For, as they affect the communication of light caliber.

So when moving the lens, aperture also changed.

3, aperture = aperture / focal length, but this is not absolutely correct. In addition, not the lens aperture diameter, the front of the lens mount diameter, or caliber, but a virtual, what does not exist, it is the above mentioned 2,3 months in a typical 4 4 zoom in zoom in charge of the two to achieve an opening angle between the concave lens, the inclination of the lens when the zoom will change.

In addition, the focal length is not correct to say, in fact, should be the image distance, not focal length ...jvc bn v408u battery

4, for a 135 SLR camera, if a shorter focal length, such as 20mm, so manufacturers have to adopt counter-telescope structure *, so that although the equivalent focal length is 28mm, but may actually be more than 70mm.

Do not you see, MA 20/2.8 aperture is only f2.8, but the diameter to 72mm, than the MA 100mm/f2.8 caliber (55mm) are big!

5, the macro lens macro trip into port, you will find the exposure combination is inconsistent with the theoretical aperture combination, especially when the zoom ratio of more than 0.5! Because at this time is much larger than the focal length of the image distance. So do not really think that the aperture size = aperture / focal length.

6, a number of lenses with a double-grating structure, such as the Minolta 135 STF and the 28-70G, the second grating will also affect the iris. 28-70G have exaggerated the first caliber, the fox that the second optical grating it may affect the pass, specifically do not know, because Fox had not seen again in addition to which it is a double-grating lens.

* Minolta and Nike have not adopted the structure of anti-ultra-wide-angle telephoto lens, but the bottom will hit the reflector, so when in use must be pre-rise to use such a reflector lens, similar to the paraxial camera. But at this time can not SLR viewfinder, you need to install a seat next to the flash axis of the viewfinder ... The metamorphosis is designed to be existed.JVC BN-V107U Camcorder Battery

Use of digital media jvc bn-v20u battery does not mean that photography would greatly reduce the cost, the cost of various equipment and accessories are still aloft. We collect some simple and practical way, can begin at home, make some equipment.

1, the reflectors may be the most useful photographic accessories. It has a reflective surface, usually white, silver or gold, can be used to fill light or soft. Top brands of the reflector is very expensive, if you budget, you can use some cheap substitute, such as silver car reflectors, reflective leather pad or circular plate wrapped in aluminum foil.

2, light beam is a great attachment, used to make the direct control of the artificial beam. Try this before buying DIY skills bar. Put a piece of black paper roll into a cone-shaped card with black electrical tape cement. Then one end fixed with adhesive tape on the flashlight into!

3, small flash diffuser to soften the hard light injection. They are not expensive, but if you prefer the DIY free substitutes, to find a clean, about one liter plastic pail. Along the bottom third of the cut. Measure the size of the flash head, trim milk tube to fit the size of the flash head. Finally fixed it with tape on the flash.

4, taken in the wild beauty is exciting, but all the equipment are exposed to in the wild to die. You might buy a fully waterproof, custom raincoat to protect the equipment in the rain. But if you do not have the extra money, find a clean plastic bag, open a hole at one end, set in the lens hood and fixed with a rubber band. Position in the eyepiece to open a small hole, setting off the eyepiece cover to be fixed.jvc bn-v712u battery

5, the filter is a very wonderful and equipment, especially the polarizer. Photographers polarizer to reduce the contrast, saturation has been reduced to improve reflective. If these filters are not in your budget, you can also use a common inexpensive (of course the effect will be worse) to replace household items - sunglasses! Most suitable for use with a tripod: the sunglasses lens held before the camera lens and the lens as close as possible. May change the final result and it was clear photos as effective as using a real polarizer so good, but this is just the beginning.

6, underwater photography is becoming increasingly popular, but the underwater photography equipment is very expensive. In fact, without spending thousands of dollars can begin the purchase of professional equipment for underwater photography jvc bn-v812u battery trip, diving in the tourist shops are leased to provide the camera and flash hood, only a small fee you can get the necessary equipment.

7, very expensive professional models, they still look photogenic family and friends to do part-time bar. In addition to cheap and because, and they are very familiar with, so their performance will be more natural. Compared with professional models, they may need some guidance, but as long as there are some magazines on hand is sufficient. You can also find some less expensive models are not known, they may be looking for someone close or a photo shoot.

8, for most of us, a fully equipped studio where the lighting is just a dream shoot models, but this does not mean we can not make a good portrait photos. Natural light not only free but also very good, especially the portraits and still life photos. It is best to make your subject is standing next to a clean, large windows, and if the sun is too strong, you can hang in the windows of thin white gauze curtains to soften the light.

9, forget about the expensive printing service bar, there are many sites offer free prints and photo gift products cheaper. Such as the popular Jessops, Snapfish and Photobox give new customers a free business card printing services and cheap gifts.

10, Photoshop is the market's best image editing software one, but its price is not the best. Fortunately, there are cheaper or even free replacement. Adobe's Lightroom, or Elements, Apple 's Aperture, Corel's Paint Shop Pro Photo Photoshop or Painter cheaper than more than half. Many software and even free for 30 days, so we must first try before buying. If you really like the free, we must not forget Picasa, a free image editing software quickly, you can create online gallery, with family, friends and the whole world share your photos jvc gz-mg20u charger

1) This very first hint may appear unbelievably obvious, however it is vital to ensure your electronic camera jvc gr-d275us battery lens is fresh new and should you are utilizing a electronic SLR, you also should make sure how the sensor is clean. that is straightforward to make an make an effort to do and will refrain away from your pictures owning any undesirable dots, smears or signifies on them.

Use a lens cloth that is only steering to acquire utilized inside the lens. Firstly, breathe inside the lens after which fresh new it owning a round motion.

For the sensor, to cut back dirt receiving onto it, often turn the electronic camera jvc gr-df550us battery away preceding to altering the lens and make an effort to make an make an effort to do so within a 'controlled' atmosphere such as the back again of the car. Essentially, make an effort to not alter the lens on the critically windy seaside or inside the desert! Most DSLR cameras have automated sensor cleanup if you turn the electronic camera on and away to be sure that may also help a lot!

I know you can often Photoshop dirt out in stills, but should you are utilizing the movement image purpose in your electronic camera then removing specs and undesirable dirt is not an straightforward choice - unless you have obtained weeks of spare time in your hands.

2) review your camera's manual. i am aware it seems boring, but 1-2 several hours using the guide as well as your electronic camera in hand will be sure that you just will understand to recognize it quickly. The sooner you can run in entire guide mode the better. It could possibly be the only method to begin pushing your photographic skills.

3) Positioning. It is vital to acquire your theme inside the excellent spot. should you are shooting a portrait or perhaps a celebration of people, location them precisely where you would like them. make sure there is positively nothing increasing away from their heads and should you desire to attribute your foundation then do so. ask for you subject(s) to proceed forwards or backwards and framing your shot with one another with your theme framed difficult left or excellent can purpose critically well. in no way be shy to proceed your subject(s) around, it could possibly be the unbelievably very best method to

4) Framing, this is what 80% of photography is all about. Look at images in magazines, watch movies and see how they are framed. You need to allow enough headroom, but not too much other wise the image can look clumsy. Don't crop half a hand or part of their head. Try not to place people directly in the centre of the frame. Soon your eye will get used to framing and you will know what looks good. The best thing I was ever taught was 'If it looks good, it is good!'

5) Lighting is really important and helps set mood and atmosphere. While using additional flash units can be a little advanced, setting your internal flash to the correct level for your lighting environment makes a big difference. This is where we come back to reading the 'dreaded' manual. On most cameras accessing the flash control is only a few clicks away on the menu. Learning how to do this will definitely help. If you have a DSLR, get an external flash and experiment using it off the camera.jvc gr-d70u battery

6) Being able to control the exposure and shutter speed manually will mean that you can expose what you want to expose for and not what the camera thinks you want to expose for. When the camera is in auto exposure mode it will expose whatever is largely in frame. For example, if you are taking a picture of your subject and a waterfall is in the background then the camera will close down the iris to expose for the white waterfall and as a result your subject will be under exposed/ dark. By knowing how to use exposure and shutter manually (which each directly affect each other) this will allow you to take control and make decisions on what part of your image you want to expose for.

7) Learning the basics of depth of field (DOF) and how exposure (F Stop) increases or decreases what is in focus will expand your creativity no end.

Shutter speed will directly affect your F Stop. Also learning about how slow and fast shutter speeds can affect your work will increase your creativity. Switching to manual focus for specific shots is also very helpful especially with macro (close up) work. This means you can set the focus to exactly where you want it to be.

8) getting your electronic camera to hand. once again this may seem obvious, but Photography is designed to be about catching a instant and moments only last a moment... So leaving your electronic camera within your bedroom or buried deep within your bag is certainly not only a winner.

9) Lighting: as shortly when you are shooting in daylight and want the best image possible, then take advantage of the sunshine for the advantage. Backlit photography can start looking fantastic, and is also really beneficial to separate your subject create a difference from its history which enable it to give a a complete whole lot much more 3D image. Just be conscious of lens flare entering the lens and create a decision as shortly when you need that effect. You can flag the flare by developing utilization of the lens hood or merely developing utilization of your hand.

When feasible use a product of light card or perhaps a reflector to bounce lumination back again onto your subjects face. You can be astonished how effective this method is also it will significantly lift the shadows away from your subjects find and increase your images.

10) make an effort to create utilization of your zoom lens like a prime lens. arranged your zoom lens to about 50mm, which could be around what our eye balls see - this could provide you with the knowing of what it is would rather hold out getting a prime lens. Then, instead of zoom the electronic camera in and out, preserve it repaired and physically proceed your do it yourself around. Get near for the subjects and straight down on their level. Don't whatsoever occasions shoot from standing up, just largely since it could be probably the most convenient.jvc bn-v107us battery

11) Don't be frightened to shoot vertical. Vertical can certainly match up specific shots, specifically portraits. try it out.

12) as shortly when you are getting pictures of people you don't know then make specific you smile! seems simple, but people whatsoever occasions appreciate it. You are getting their image so it's the minimum you can do. It will help them really feel much more at ease plus they may even smile back.
