The flash is a way to bring extra light with you and brighten many kinds of pictures. On the other hand, I have found that most people don’t really know how to take advantage of the flash that is built into their camera, so in this chapter I discuss techniques like fill flash, red eye reduction, and bounce flash. Lighting isn’t just about using a flash, either. You can use a reflector to spread light around for a more pleasing effect, and play with the white balance built into your camera for better lighting control as well.<br /><br />These days, most digital cameras have an electronic flash unit built right into the camera body. The flash is designed to fire for a very short period of time and illuminate your scene in one of two ways:<br />1) As the main source of light indoors or in the dark<br />2) As a secondary source of light to fill in shadows when you’re shooting in bright light, such as outdoors<br />In general, your flash will probably know when to fire and can illuminate most pictures without your direct intervention. When your camera is set to the fully automatic exposure mode, the flash will probably come on as needed and not fire when it is not needed. On the other hand, you can probably figure out when you need a flash more effectively than your camera can. There will be situations when you may want your flash to fire when it would probably stay off, and vice versa. That’s why your camera has several flash modes to choose from.Adminhttp://www.blogger.com/profile/07483008905314879651noreply@blogger.com0tag:blogger.com,1999:blog-8086415182107040106.post-4513019498994958772007-07-28T09:33:00.000-07:002009-04-19T06:32:59.881-07:00Flash Modes(note: Difference camera brand may difference sign modes)<br />In this digital age, “on” and “off” are just too easy. Instead, your camera’s flash has three or more modes, each intended for a specific photographic situation. Here’s the rundown of your options. Your camera may not include all of these features, so you might want to check out your camera manual before you get your heart set on trying all of them out. Your camera should have some, if not all, of these modes:<br /><ul><br /><li><strong>Off </strong>This one is easy. When you set your camera to this mode, no matter how strongly your camera believes that you need extra light, the flash will not fire. This is handy for situations where you are not allowed to fire a flash, such as in a church or a museum, or when you’re too close to the subject and think you might overexpose it. You may also want to turn off the flash in many night photography situations.</li><br /><li><strong>Auto</strong> This is the standard mode that you’ll probably want to leave your flash in most of the time. When set to auto, the flash determines whether it needs to fire based on the amount of light in the scene. This is a good mode to use when you don’t want to think about whether the flash needs to fire. For typical snapshot photography, just set your flash to auto. </li><br /><li><strong>Forced</strong> This mode goes by many different names depending upon the camera you are using. Sometimes called “forced flash,” “fill flash,” or just “on,” forced flash is probably the most appropriate name. When you set your camera’s flash to this mode, it will fire regardless of how much light is available. Why would you want to use this mode? It’s most useful as a fill flash: when you’re shooting outdoors in natural light, the fill flash can erase shadows that would appear based on the way the sun hits your subject. Fill flash, or forced flash, is great for portraits. </li><br /><li><strong><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgWATz2SvWn_-uopiPlGN1eSo2nVcznDomr6PYKx0XScul7k1n14kyPreO1Cwb1mqtV86-aSVccZELCsJ5Jr35qAzqo9UzpwC_kgnQkCGiq6KwtHp8wU1o3cEKrYQc9L2utYtyBCMoRL0fI/s1600-h/flash_redeye.jpg"><img id="BLOGGER_PHOTO_ID_5092277344051988530" style="CURSOR: hand" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgWATz2SvWn_-uopiPlGN1eSo2nVcznDomr6PYKx0XScul7k1n14kyPreO1Cwb1mqtV86-aSVccZELCsJ5Jr35qAzqo9UzpwC_kgnQkCGiq6KwtHp8wU1o3cEKrYQc9L2utYtyBCMoRL0fI/s200/flash_redeye.jpg" border="0" /></a>Red eye</strong> Red eye reduction mode has become extremely popular in all sorts of cameras, both digital and analog. By pre-flashing the camera flash several times quickly right before the picture is taken, the red eye reduction mode forces your subject’s pupils to close down to a smaller size, thus decreasing the chances that they will reflect the light of the flash. When you use this mode, remember that it will take a fraction of a second longer for the picture to be taken; don’t pull the camera away as soon as you press the shutter release, or you’ll blur the picture. If you’re photographing people in a dark room, however, this mode is probably worth the extra time. You do not need to use red eye reduction outdoors or in bright light. </li><br /><li><strong><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEheAv8VKt2R7K-Xz74RyYI7ApIC15z1QgkWeCeOFe7apdC9GBZJ_9ZjnMXatmlsQkQZ15SxU7va0fYnPOFtA3A7dH_Ti_0uyOV-nBNqLuqwmI7iP5K1WmsfWleo_wDUJKK-DIm-eZJpFu1n/s1600-h/flash_low.jpg"><img id="BLOGGER_PHOTO_ID_5092278873060345922" style="CURSOR: hand" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEheAv8VKt2R7K-Xz74RyYI7ApIC15z1QgkWeCeOFe7apdC9GBZJ_9ZjnMXatmlsQkQZ15SxU7va0fYnPOFtA3A7dH_Ti_0uyOV-nBNqLuqwmI7iP5K1WmsfWleo_wDUJKK-DIm-eZJpFu1n/s200/flash_low.jpg" border="0" /></a>Low power</strong> Some digital cameras let you control the power output of the flash. You might be able to reduce its intensity by 50 percent or more. You can use this mode when you are using the flash to fill in shadows, or when you are taking a close-up and a full flash burst would overexpose your subject. </li><br /><li><strong><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhAwhbbKMwvRZZJWe4DLaB1CZPNRvq0klhgImdscDKj8tuIxiSju7WG130EVzo-LteEAp958iThd3AtmTCjg6Sj6YtgzjJ_zNfDaZG1H81MiQYKuv53ESKkgxrs3a0Uw_8gbDAt_HlXPb9u/s1600-h/flash_slow.jpg"><img id="BLOGGER_PHOTO_ID_5092279521600407634" style="CURSOR: hand" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhAwhbbKMwvRZZJWe4DLaB1CZPNRvq0klhgImdscDKj8tuIxiSju7WG130EVzo-LteEAp958iThd3AtmTCjg6Sj6YtgzjJ_zNfDaZG1H81MiQYKuv53ESKkgxrs3a0Uw_8gbDAt_HlXPb9u/s200/flash_slow.jpg" border="0" /></a>Slow</strong> In the world of 35mm photography, this slow setting is sometimes referred to as a rear curtain flash. Other cameras, such as Nikon digitals, call it Slow Sync. Of course, that name may not help you understand what the slow setting does. When you set the camera to slow flash, it fires the flash at the tail end of the exposure. It’s used most often at night, when the exposure is long (such as a second or more). What does it do? Suppose you were trying to take a picture of a car driving down the street. With an ordinary flash exposure, the flash fires right away, thus freezing the car at the start of the frame. In a long exposure, you will then see headlights cut through the car and out of the frame. The slow mode, however, saves the flash for the end. In a picture taken with this mode, you will see headlights that travel through the frame and then meet up with the rear of a flash-frozen car. The car is leaving the picture at the end of the exposure, just like it should. As you can imagine, you won’t use this mode all the time, but it is indispensable when you need to get a certain kind of long-exposure photograph.</li></ul>Adminhttp://www.blogger.com/profile/07483008905314879651noreply@blogger.com0tag:blogger.com,1999:blog-8086415182107040106.post-3512156144437471762007-07-28T09:28:00.000-07:002009-04-19T06:35:05.428-07:00The Range of Your Flash<p>How far will the light from your flash travel? That’s something you need to know if you expect to get the most out of your flash. The flash built into most digital cameras is not extremely powerful; at best, you can expect to get a range of about 20 feet. To find the range of your camera’s flash, refer to the owner’s manual that came with your camera. <strong>You can almost always find the flash range listed in the specifications section of the manual. If you cannot find the range of your flash listed there, assume it is no more than about 15 feet.</strong></p><ul><li>The range of your flash also depends upon two other factors: the current ISO (light sensitivity) setting on your camera and the focal length setting of the zoom lens. The first factor—ISO—is pretty obvious. The more sensitive the CCD is made to light, the more effective the flash will be. </li><li><br /><div align="left">It is an unfortunate side effect of zoom lens technology that <strong>when you increase the focal length to telephoto, you typically process less light than when you are using a wide angle or normal focal lengths.</strong> Since there’s less light getting through the lens barrel to the CCD at telephoto magnifications, the flash has less range.</div></li><li><br /><div align="left">If you’re used to the great range you would get from an external flash unit mounted on top of a 35mm SLR camera, you might be disappointed by the range from a digital camera flash. It stands to reason, though, that the small flash built into a digital camera could not have the same power as the large flash head—with lots of AA batteries—mounted on an SLR.</div></li><li><br /><div align="left">That means you’ll have to be aware of how far you’re trying to get the flash to throw light, especially at night or in very dark conditions. <strong>If your subject is very far away, such as 25 feet or more, it is unlikely that the built-in flash will have any effect at all on your photograph.</strong> In fact, some digital cameras disable the flash automatically when they sense that the lens is focused on infinity. You might want to check your camera manual or experiment to see if that feature applies to your camera.</div></li></ul>Adminhttp://www.blogger.com/profile/07483008905314879651noreply@blogger.com0tag:blogger.com,1999:blog-8086415182107040106.post-29336788241405150262007-07-28T09:07:00.000-07:002009-04-19T06:36:13.026-07:00Flash: Getting Too CloseBelieve it or not, it’s possible to get too close to your subject as well. Some digital camera flash units overexpose the subject when you are within a foot or two of that person or object. Since you know about the light-reducing properties of a telephoto lens, you might expect that you can get closer when you zoom in than if you are zoomed out. And you’d be right; with a typical camera, you cannot shoot any closer than about 3 feet when set on normal zoom, but you can shoot to within a single foot if you are zoomed in to telephoto.<br /><br />close-up photos are easy to overexpose if you leave the flash turned on. There are a few ways to work around this problem, depending upon what your flash unit is capable of doing:<br />1) Turn the flash off completely and shoot with natural light.<br />2) Bounce the flash off a plain white reflector, such as the ceiling or a reflector card. You’ll probably need an external flash unit to bounce, though.<br />3) Reduce the flash’s power setting to 50 percent or 25 percent.<br />4) Cover the flash with a tissue or gel (available at any camera shop) to reduce its intensity.<br /><br /><strong><span style="color:#cc0000;">=TIP=</span></strong><br /><strong>For many digital cameras, there’s an optimum range for your flash photographs. Try to stay between about 5 and 14 feet from your subject. Avoid using the flash in situations where the subject is more than about 15 feet away or closer than 3 feet.</strong>Adminhttp://www.blogger.com/profile/07483008905314879651noreply@blogger.com0tag:blogger.com,1999:blog-8086415182107040106.post-66168400536736174222007-07-23T08:18:00.001-07:002007-07-24T09:43:48.260-07:00Look at your budget for a camera<a href="http://www.robgalbraith.com/data/1/rec_imgs/2083_powershot_s5is.jpg"><img style="FLOAT: left; MARGIN: 0px 10px 10px 0px; WIDTH: 200px; CURSOR: hand" alt="" src="http://www.robgalbraith.com/data/1/rec_imgs/2083_powershot_s5is.jpg" border="0" /></a><br /><br /><div>The more expensive the camera, the more features you find.

This determines the area of coverage from narrow to wide. Digital cameras generally rate their focal lengths as equivalent to 35mm film camera lenses.<br />20mm or less = Extreme Wide Angle<br />24mm to 35mm = Wide Angle<br />50mm to 80mm = Normal<br />100mm to 300mm = Telephoto<br />400mm and above = Super Telephoto<br /><br /><strong>Macro mode or lens<br /></strong>This enables close-up photos of small objects. Good cameras have a macro mode built into their lenses.<br /><br /><strong>Normal lens</strong><br />Usually a 55mm focal length equivalent and is the most commonly used fixed lens.<br /><br /><strong>Wide angle<br /></strong>A lens less than 35mm focal length equivalent. It allows shooting a more inclusive image in tight spaces. Lenses much wider than 28mm are referred to as fish-eye lenses because of their image<br />distortion.<br /><br /><strong>Telephoto Lenses<br /></strong>with more than 55mm focal length equivalent. These usually range from 75mm to over 1000mm and are used to snap photos of subjects at a distance.<br /><br /><strong>Zoom lenses</strong><br />have variable focal lengths and can be changed from wide angle to normal to telephoto. Digital cameras feature both optical and digital zooms.

Optical zoom maintains its quality at all levels. This is the most important type of zoom in a digital camera. A 10x zoom on a digital camera is roughly the equivalent of a 28mm to 200mm zoom lens on a 35mm film camera. The zoom factor of most optical zoom lenses ranges from 1.2x to 10x.<br /><br /><strong>Digital</strong><br />Digital zoom does much the same thing as zoom in Photoshop. The camera selects part of the digital image and saves only that part of the photo. Digital zoom reduces the actual resolution of your image, increases noise, and emphasizes shaky camera syndrome. Avoid using digital zoom if possible. If you need to accomplish a digital zoom effect, cropping the best photo you can get in Photoshop later is best. Digital zooms range from 2x to 10x.<br /><br /><strong>Zoom Ratio<br /></strong>The difference between the size of the image that is projected onto the film at the widest (or smallest focal length) setting of a zoom lens and the size at the narrowest (or longest focal length). A 10x zoom lens magnifies the image in the narrow end of the lens exactly 10 times as much as the image at the wide-angle end.</div>Adminhttp://www.blogger.com/profile/07483008905314879651noreply@blogger.com0tag:blogger.com,1999:blog-8086415182107040106.post-86678865660953716252007-07-23T06:07:00.000-07:002009-04-19T06:39:03.223-07:00Look at camera tripod<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh6KC8rO7rpDY7ebq3aKNeVsY1KrwbaLv8Xp1Jo_toxVkuzeoPe60TcCI3aqfvNA_t2G0HdAHzf6ohuHSoG_YGWacmIjVrNlH0FYULaKKpSLtVhouZwOeMi4cOGZlT5SW7ksVSfwcx0pQ2f/s1600-h/cam-tripod.jpg"><img id="BLOGGER_PHOTO_ID_5326396541989762706" style="FLOAT: left; MARGIN: 0px 10px 10px 0px; WIDTH: 133px; CURSOR: hand; HEIGHT: 200px" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh6KC8rO7rpDY7ebq3aKNeVsY1KrwbaLv8Xp1Jo_toxVkuzeoPe60TcCI3aqfvNA_t2G0HdAHzf6ohuHSoG_YGWacmIjVrNlH0FYULaKKpSLtVhouZwOeMi4cOGZlT5SW7ksVSfwcx0pQ2f/s200/cam-tripod.jpg" border="0" /></a><br /><div><a href="http://www.porta-jib.com/photos/lw-tripod.jpg"><span style="color:#cc0000;"></span></a><span style="color:#cc0000;">The tripod is a very important factor for us, photography.

If your camera uses a standard sized battery, it’s probably AA. Alkaline batteries in cameras used with a flash last only a few photos. This is an expensive solution for frequent use.<br /><br /><strong>Lithium</strong><br />Disposable batteries. These may be called “photo batteries.” They last well but are very expensive. The are available in most formats.<br /><br /><strong>Nickel Cadmium Rechargeable.</strong><br />These must be fully discharged before recharging to avoid “charge memory” and poor performance. Be careful not to overcharge.<br /><br /><strong>NiMH</strong><br />(Nickel-Metal Nickel-Metal Hydride are excellent batteries and are rechargeable. Hydride) These are the best value. They come in all standard sizes. Many proprietary batteries used in digital cameras are NiMH. These are powerful batteries and last about 400 charges.<br /><strong><br />Lion<br /></strong>(Lithium Ion) Lithium ion batteries are a good choice. They don’t have “charge memory” and they last twice as long as NiMH batteries. These are usually after-market optional batteries and are purchased as extras. These are newer and not as widely available. They last about 400 charges.<br /><br /><strong>External battery</strong><br />You can power some cameras through the AC power socket using packs external battery packs. These come in many of the previous formats. These can be much larger with greater storage capacity. Clip them to your belt with a wire running to the camera. These are great on vacations or long shoots like weddings.<br /><br /><br />More expensive cameras may use proprietary batteries rather than standard AA, AAA, and so on. This means that you must purchase the manufacturers’ batteries or after-market batteries designed for your camera when you need extras or replacements.</div>Adminhttp://www.blogger.com/profile/07483008905314879651noreply@blogger.com0tag:blogger.com,1999:blog-8086415182107040106.post-60122767785983524952007-07-23T06:05:00.001-07:002007-07-24T04:05:42.607-07:00Look at picture format<span style="color:#cc0000;">These are types of picture format used in digital camera:</span><br /><strong>JPEG </strong><br />Lossy This file format is the most common. It’s universally recognized. You can select the amount of compression and subsequent quality or loss of quality in the camera or in the computer.<br /><br /><strong>TIFF<br /></strong>Lossless TIFF is a standard photo or digital publishing format. It can be somewhat compressed but in order to lose no quality, the amount of compression is limited. This is a good finished file format and retains high image quality. You can select to shoot TIFF photos with many cameras.<br /><br /><strong>CCD RAW</strong><br />Lossless You can set the more expensive prosumer and professionalcameras to save the data directly from the CCD chip in the camera. This saves a huge amount of image information and is used by professional photographers and graphic artists to gain maximum image quality and flexibility. It’s a very large file and severely limits the number of images that can be stored on common memory cards.<br /><br />When a lossless compression image is uncompressed, its quality matches the original source. Lossy compression degrades images to some degree, and more compression equals more image loss. Use the least compression you can for the original image. You can always compress it more with editing software.Adminhttp://www.blogger.com/profile/07483008905314879651noreply@blogger.com0tag:blogger.com,1999:blog-8086415182107040106.post-37735489875010614732007-07-23T06:02:00.000-07:002007-07-24T10:21:29.099-07:00Look at camera mode<a href="http://www.thetechlounge.com/files/articles/287/camera_mode_dial_sm.jpg"><img style="FLOAT: left; MARGIN: 0px 10px 10px 0px; WIDTH: 200px; CURSOR: hand" alt="" src="http://www.thetechlounge.com/files/articles/287/camera_mode_dial_sm.jpg" border="0" /></a><br /><br /><div>Choosing a camera is always a compromise.

Prosumer cameras split the difference between size and features.<br /><br /><strong>Panoramic</strong><br />Some digital cameras can capture a single-image panorama; others feature multiple-image panorama that you can assemble in the computer later.<br /><br /><strong>Multiple exposures</strong><br />Takes a preset number of images when you hold the button.<br /><br /><strong>Tripod mount<br /></strong>Allows you to attach a tripod to the camera.<br /><br /><strong>Self-timer<br /></strong>Camera automatically shoots after a set period of time.<br /><br /><strong>Remote control</strong><br />Camera may be set and operated from a distance.<br /><br /><strong>Date/time indicators</strong><br />Stamps the header of images with the time and date the photo was shot. This information doesn’t show up on the image but the camera or software displays it while being viewed.<br /><br /><strong>Sound recording</strong><br />Enables the recording of audio notes or comments with the camera’s built-in microphone.<br /><br /><strong>Software</strong><br />Most digital cameras are bundled with editing and other software. The software supplied might be a factor when choosing a camera.<br /><br /><strong>LCD viewfinder</strong><br />Better cameras include these. Choose the largest available. These use battery power.<br /><br /><strong>Eyepiece viewfinders</strong><br />Most cameras have these even if they have LCD viewfinders. These work best in bright light. They also increase battery life.<br /><br /><strong>Through the lens viewing</strong><br />Single lens reflex professional cameras allow viewing directly through the camera lens.

The wider angle lens can make the more distortion by the vertical line (90 degree) will slightly bend into the centre of the picture. However the high quality of wide lens can reduce the problem of distortion and also the more quality the more price. We should use the wide lens with the view picture because it give the more depth of field. Also we can take the macro by the wide lens but it will give the wider background.<br /><br />The new style of these type of lens will be designed in <strong>INVERTED TELEPHOTO</strong> that make the higher distance from lens to image sensor/film but it still can give the same focal length. Besides, it has <strong>the Shift lens or Perspective Control Len</strong>s that designed for architecture use so it can solve the problem of distortion (the vertical line (90 degree) will not slightly bend into the centre of the picture).

Besides, the outside of its tube will have the ring for control the aperture and focal length (meters, feet). The more piece of lens the more expensive.<br /><br /><strong><span style="color:#cc0000;">2. Lens and angle receivable</span></strong><br />The SLR digital camera can switch its lens. The difference brand of camera may have the difference type of mount of lens however many difference brands of camera can use the same lens. So should be carefully when buying new lens. Besides, nowadays there are many independent brands which can produce the many type of lens in the lower price which can support many brand cameras.<br />Below is the focal length compare with the degree of the view receivable:<br /><br /><strong><span style="color:#cc0000;"><br />3. The focal length of lens</span></strong> </p><ul><li>Starting from a image sensor/ film until the first piece of lens. The higher focal length will give the narrow view image but the shorter will give the wider view image Also the higher focal length lens can zoom in more than the short focal length lens. </li></ul><p>For the aperture in each lens are difference depending on the type of lens specially if you want to take the portrait picture of human , you may need the very high aperture to blur the background of your object. </p>Adminhttp://www.blogger.com/profile/07483008905314879651noreply@blogger.com0tag:blogger.com,1999:blog-8086415182107040106.post-82776208284457385302007-07-18T10:16:00.000-07:002008-12-10T23:52:33.697-08:00Maximizing Depth of FieldThe three ways to maximize the depth of field in your image are:<br /><p align="center"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiPpwJDhcQb9DPgwStrc5ag0yhR1Yx_KxR5R5QGCZtFUc7SaHxEvGg65KRNaZPwOFhy4V7Us2GQku0p9vzTkO2xlObZVRxu37c1M4AfDCtY1x3UkF-O0RzVWVFlO_uTkQbADdBsJlTeaO4j/s1600-h/3formaxdepth.gif"><img id="BLOGGER_PHOTO_ID_5088589225512720354" style="CURSOR: hand" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiPpwJDhcQb9DPgwStrc5ag0yhR1Yx_KxR5R5QGCZtFUc7SaHxEvGg65KRNaZPwOFhy4V7Us2GQku0p9vzTkO2xlObZVRxu37c1M4AfDCtY1x3UkF-O0RzVWVFlO_uTkQbADdBsJlTeaO4j/s400/3formaxdepth.gif" border="0" /></a></p><br />1) Use a lens with a short focal length: wide or normal lens<br />2) Focus on a distant subject. If you’re trying to get both a nearby tree and a more distant house in focus simultaneously, for instance, focusing on the house, rather than the tree, is more likely to deliver both subjects in focus.<br />3) Use the smallest aperture (high f/value) you can, such as f/11 or f/16.<br />Not unpredictably, you can minimize the depth of field in a picture by doing exactly the opposite of these things. :)<br /><br />If you don't clearly understand about above, please read The Depth of field: 3 factorsAdminhttp://www.blogger.com/profile/07483008905314879651noreply@blogger.com0
