Using a Light Meter
You will come across two types of metering:
- The first kind is reflective metering. The actual meter within your digital camera is basically reflective metering. It calculates the quantity of light that will bounce off of from your subject into your digital camera lens. Your digital camera makes use of this info to find out variables such as the aperture, ISO and shutter speed if it is fixed on auto-mode.
- The 2nd kind of metering is known as incident metering. Hand-held light meters are generally incident meters. The incident meters calculate the light shimmering on the subject. Simply because they are not relying on the reflective attributes of light to provide you with a reading, they are far more precise when compared with your camera interior meter. The dome that comes in reflective meter contains sensitive sensor that calculates the light entering it from all possible angles.

Sigma 100-300 mm
The lens also comes with a new multilayer coating that offers a great color performance and at the same time reduces ghosting or flare created by reflections. By design, the Sigma 100-300 will also maintain a minimal light fall-off and ensure that the peripheral brightness is of superior quality. You should expect high optical performance, which is displayed all through the zoon range.
With the Sigma 100-300, you will not worry about aberrations because the two SLD glass elements in the front and rear of the lens enable optical corrections to offer superior quality all through the zoom range. The lens is also available with an inner focusing system, which is responsible for eliminating the rotation of the front element of the lens.
Users of the Sigma 100-300 will benefit from the smooth movement of the zoom and focus rings because they come with the right resistance levels. The rings are made of rubber and this makes it better to handle and easy to turn. The focusing ring will end in soft stops on the different spectrum of focus. Sigma 100-300 also comes with 150 degrees of turning fidelity, making it easier for the users to focus the lens manually. The filters attached to it will not rotate as the lens focuses.

Sigma 70-200mm
When it comes to color and contrast, the Sigma 70-200 is excellent. The creamy background blur is facilitated by the presence of the 9-blade apertures. The chromatic aberration is well controlled, but the flare is not so, especially in higher focal ranges. At the 200mm mark, you need to have the sun and other sources of bright light far out of their pictures so that they do not end up with flare that robs the photo of its contrast.
You will not have to worry about distortion when using the Sigma 70-200. The lens shows a little barrel distortion on wide end and pincushion distortion at 100mm, which increases as it reaches the 200mm focal length. When it comes to vignetting, there will be little shading from 135mm to 200mm when the lens is at f/2.8. This phenomenon is especially visible if you use it with full frame cameras.
In order to avoid such problems, it is important that you stop the Sigma 70-200 lens down one or two stops from the maximum aperture. The users will also benefit from the fast and silent autofocus thanks to the Hyper Sonic Motor (HSM). The HSM is not only crucial for internal focusing but also helps in internal zooming. The front element of the lens will not rotate, making it possible to use it with the petal shaped hood.

Sigma 50-150mm
While the flare is well controlled at the 50mm mark, it is at its best at the 150mm. For the focal length, the transition is linear. Users will start noticing a mild barrel distortion in the center of the frame when the Sigma 50-150 lens is at 50mm and pincushion distortion at 80mm and 150mm. It can be quite strong on those two focal lengths.
When it comes to chromatic aberration, it is noticeable at 100mm at the corners, although it is not present at 50mm and 70mm. It becomes even stronger at the 150mm mark. With the Sigma 50-150, users will also experience vignetting at the corners at 150mm. Fortunately, they can clear up all the shaded region by f/4 and f/5.6 for corners that are evenly lit.
The Sigma 50-150 also comes with nice physical features. It has the HSM mechanism that is suitable for internal and rear focusing mechanism. The AF is not only moderately fast but also quiet. Manual focusing will produce some squeaking noise, but it is not loud or significant at all.

Sigma 18-200mm OS
It comes with two SLD glass elements and two hybrid aspherical lenses that will correct the different types of aberrations. The housing of the Sigma 18-200 OS is not only compact but also light in weight. It weighs 14.3 ounces and measures 70mm in diameter and 78.1mm in length. It also comes with a new lens coating that will not only reduce both flare and ghosting but also b ring about an optimum balance in color.
What makes the Sigma 18-200 OS different from its predecessor is the Optical Stabilizer function - a unique technology from Sigma. This system applies tow sensors that will detect the vertical and horizontal movement of the camera so that it compensates the camera shake. This makes it a great choice for those people looking to take great handheld shots. The users will be able to capture photos in low light conditions without using a tripod.
The optical performance of the Sigma 18-200 OS is facilitated by a special low dispersion (SLD) lens and 3 aspherical glass elements. They will correct the aberrations and offer high quality images across the zoom range.

Sigma 18-200mm
Similar to other lenses from sigma, the Sigma 18-200 comes with the new lens coating that reduces ghosting and flare - one of the problems that are popular in digital cameras. The coating will also create the best color balance. The maximum magnification of the lens is 1:4:4 while the minimum focusing distance is 45cm at all focal lengths.
The Sigma 18-200 design also features an inner focusing system, which limits the rotation of the front lens. This makes the product the best when it comes to using the petal-shaped lens hoods and polarizing filters. The overall lens' length does not change when the users are focusing, making it convenient to handle and easy to use. The users will not have any problems with zoom creep when transporting or traveling thanks to the zoom lock switch.

Sigma 24-70 HSM
Like other Sigma lenses, the Sigma 24-70 HSM comes with a super multi layer coating that eliminates ghosting and flare and at the same time to offer high quality image. It also comes with Extraordinary Low Dispersion (ELD) glass elements and two SLD (Special Low Dispersion) glass elements as well as three aspherical lenses to offer correction on all aberrations.
With the Sigma 24-70 HSM, the superior quality performance is ensured all through the zoom range. With it the users will benefit from the quiet and high-speed autofocus as well as a smooth manual focusing. The lens has a minimum focusing distance of 38 mm as well as a magnification ratio of 1:5:3. It also comes with a diaphragm with 9 blades to create an attractive out of focus blur.
The users will also benefit from the sharpness and accuracy of the Sigma 24-70 HSM lens. The sharpness will be seen in all apertures and focal lengths. However, it will drop sharply at 70mm when it is wide open. The users can avoid this by stopping down to at least f/4 so that they get the best images.

Sigma 18-50
In terms of sharpness, the Sigma 18-50 comes with a sharp image quality at different focal lengths. However, the sharpness will lower when you open up the lens to f/2.8, especially at the corners. For this reason, you should stop down to f/4 in order to bring the sharpness in focus. The sharpness gets better to about f/11, but after that it starts to decrease because of diffraction. At f/22, the images are not as sharp, and it is even worse as compared to when the Sigma 18-50 lens is put on wide open.
The focal length of the Sigma 18-50 will keep the image quality under strict control. The users will also benefit from the macro feature which allows the users to get very close to the subject. Some of other benefits they will enjoy include the lightweight and small size of the unit, which allows them carry it without any problem.
The users will also enjoy a correction of the color aberration, thanks to the presence of the SLD (Special Low Dispersion) and ELD (Extraordinary Low Dispersion) glass. It also comes with a multi layer coating that is characteristic of most Sigma lenses. The coating on the Sigma 18-50 will help in the reduction of flare and ghosting, making sure that the images are of high quality. The two aspherical glass elements will also help in the correction of distortion, allowing users get the best photos.

Sigma 17-70 OS
The buyers will enjoy the F2.8 aperture of Sigma 17-70 OS because it can be used in different situations such as macro, portraits, general photography as well as sports. The aperture has also made it possible for the users to engage in hand held photography throughout the zoom range and at high auto focus speed. Those who love close up photography will also benefit from Sigma 17-70 OS because of the focusing distance that comes with a minimum of 22cm and a maximum magnification 1:2:7 ratios.
The Optical Stabilizer (OS) function provides users with shutter speeds that are almost 4 stops slower than would usually possible. The Sigma 17-70 OS also comes with three aspherical lenses and a single Extraordinary Low Dispersion (ELD) glass element that will provide corrections to different types of aberrations. This assures the users of high quality image all through the zoom range.
Just like other types of lenses from Sigma, Sigma 17-70 OS comes with a super multi layer coating that will decrease ghosting and flare, and at the same time offer images with high contrast. Apart from that, it comes with HSM, which will ensure a high speed and quiet Auto focus. The outstanding thing in this lens is the rounded 7 blade diaphragm, which causes an attractive blur to the image areas that are out of focus.
When it comes to vignetting, the buyers of the Sigma 17-70 OS will experience some of at the widest apertures. In order to avoid this, they need to get down one stop at the every focal length. Chromatic aberration is well controlled and the users can ignore the focal length and apertures. Users will also enjoy a smooth operation when it comes to manual focusing. The focus ring will rotate during autofocus. The polarizing filter will not be a problem because the front lens will not rotate.
When it comes to the build, this lens is decent and better to handle. It is good for different types of situations because of the fast and silent autofocus as well as the great OS performance of the Sigma 17-70 OS.

Canon PowerShot SX130IS
One of the primary things I would like to discuss concerning this camera would be that it is included with a 12 times zoom lens, which is impressive for a camera such as this. For folks who like to take closeups but are unable to get close to the subject you're going to find that the 12 times zoom lens is a thing that is very impressive. You need to also understand that the zoom function can be quite useful while you are trying to capture one thing but do not want to capture something else in the picture.

Nikon Coolpix P510
The device is equipped with a 24mm-1000mm lens and a 16.1-megapixel image sensor. Clearer, brighter, and highly focused images are the result of this union of features. 1080p images are capable of being captured even in darker or high sunlight situations, as well as movies and videos. Detail on even compromising images is of excellent clarity due to the image sensor.
Image stabilization features integrated in the Nikon P510 lets the user capture moving targets without heavy blur and unfocused parts of the image. Fast auto-focusing techniques allow for a quick, sudden capture without having to mess with the other settings of the camera. This allows for quick captures that do not have the time to be adjusted accordingly.
42x zoom capability lets users examine subjects from far off and still remain focused and detailed. This is a good feature for wildlife photographers who desire to capture a close image without disturbing the wildlife or its habitat. Distant zooming capabilities help in exposing minute details other devices may miss.
High resolution images and movies are both possible with the integrated features found in the Nikon P510. Its 16.1-megapixel image sensor lets captures include more clarity and detail than other devices. It is also capable of shooting up to five shots per second with a high speed shooting feature, for those needing to capture each frame on its own.

Tricks and Tips to shoot Green Screen
Buy a high quality backdrop
* Make sure that the chromakey green muslin backdrop used by you is made of high quality fabric.
* For good quality pictures, the backdrops must be made of durable muslin material and must be 100% cotton to absorb light.
* The backdrops must be seamless and flawless to avoid any wrinkles in the photographs.
* Buy a backdrop which is easy to fold and carry so that it can be used for on locations shoots as well.
Fix the backdrops properly
* Make sure that the green screen backdrops are fixed properly to avoid any folds in the photographs.
* The backdrop must be fixed at a place where lighting is proper. Lack of proper lighting can affect the quality of the images by leaving shadows in the images taken.
Use good quality software
* Use good quality chromakey software to edit the photos taken against the green screen backdrop.
* The software will help in eliminating the green screen properly from the photographs and you can add the images of your choice to make the pictures look beautiful.

Light plays
Although there is not really the standard method, how to use lighting when taking pictures, there are only the basics of what to do when taking pictures. For example, always avoid the subject of the image with the light behind them, or are listed as new lighting. This makes the subject is dark, except, of course, if you want a dramatic effect to your photos. The best thing to do, then take pictures with it, in front of a light source so that the picture that emerges is clear...
Another thing to avoid, images of metal or glass directly. This leads to a reflection of the so-called flash or diffused light. What do I do next in order is a clear picture of your digital camera into a 45 degree angle with the surface of the metal flashing on. However, understand that it is wrong if the photo shows a torch. It 's perfectly fine, especially if you have it, according to a particular effect on the images. To operate with respect to the type of light, because the softer light to create shadows hold. On the other hand, the direct light in different colors which are very ideal if you want to play, to create your pictures.

The basic colour modes in photograph
The basic colour modes are Red, Green, Blue (RGB) and Cyan, Magenta, Yellow, Black (CMYK). They are known as colour spaces and they determine how images are seen and reproduced.
Electromagnetic radiation comes in the form of wavelengths and its total range is known as the spectrum. The range covers gamma rays, X-rays, ultra-violet, visible light, infra-red, radar, microwaves, various radio waves and extremely low frequencies.
The only part of this spectrum which can be seen by the human eye is a very small section in the middle seen as white light. White light is refracted into its component colours of red, orange, yellow, green, blue, indigo and violet, which we see as the rainbow colours. The primary colours are red, green and blue.

Food Photography
When lighting food we want to avoid harsh shadows and highlights. To do this use a soft, diffused light source. A shaded area with reflected natural light can work well. For artificial light, try lights reflected from large umbrellas, or large softboxes.
Don't light your subject directly from the front, as the light will fill in all the shadows, giving a flat image with no texture. Instead light from the side to bring out the texture and details in the food.

The Tokina 50-135 lens has a high quality build and construction
As far as the aperture is concerned, is very fast and constant at f/2.8. The lens incorporated SD elements which compensates the chromatic aberrations. Chromatic aberrations are a big concern for photographers and Tokina have addressed that issue with this Tokina 50-135 lens as they have used SD technology which reduces the chromatic aberrations. The SD feature not only reduces the chromatic aberrations but also it makes the lens produces sharp and high contrast images. The quality of the image is quite high and optical quality this lens is commendable.

Cameras allow an External Flash
Current camera flashes are either flashtubes, which combine a tube filled with xenon gas with a high voltage charge to emit a flash of light, or microflashes. Microflashes are high-voltage flash units which give a flash of light with for a sub-microsecond. They are frequently used by engineers or sometimes for examining fast moving objects or reactions.
Although they don't yet have the power to replace xenon flashes, LED flashes have been used in camera phones. The major advantage of LED over xenon is its ability to operate at a low voltage, on a tiny scale and with increased efficiency.

Important Pointers for The Contest
Here are important pointers:
1. The theme is important.
Make sure your photograph or series of photographs fit well into the topic of the contest, this is one of the most important factor, your image can be great, beautiful, technically correct but if this is a portrait and you submit it to landscape photo contest you will not get any recognition.
2. Again topic it important.
I know you will not submit portrait to landscape contest but i want you to understand that this is very important. Some contest have 10 or more categories go through it and understand what will the judges look for and what category does your work fit best.
3. Follow the rules.

Quality Panorama Photo Shooting Tricks !
- 1. You should start by planning your shot sequence, because when you are shooting pictures for panorama, you will be taking ten or more pictures in a sequence. It is best to do a dry run looking through the viewfinder to plan the entire sequence in advance on the way you will arrange your shots.
- 2. Though you can shoot photo sequence in any direction, but it is best if you can shoot from left to right, as it becomes much easier to make sense with your shots when you are viewing them on your computer, and you will get them in best order in the software.
- 3. In panoramic photography, your photos should overlap to enable software to stitch them perfectly. You can very easily stitch your photographs with a twenty percent overlap or even less. Having said that, thirty to fifty percent overlap is recommended. A large overlap in panoramic photography delivers you a adequate room for fine-tuning your final results.
- 4. For enhancing the vertical field of view by about fifty percent, you should turn your digital camera sideways for shooting your photos in portrait position. You will have to shoot more frames for covering the same scene, but with this maneuver, you will get significant vertical coverage.

Black and White Photography
1.Find a location.
It can takes for months to find a great location, i go back to the same location many times before I get lucky to encounter great light and everything connects perfectly. Sometimes it just happens and you will be able to walk into a great place where light , contrast and composition are perfect, most of the times you will have to go back, even in you are experienced photographer you will go back to the same location to improve the landscape you see.
Finding location is first step, you have to find specific point from where you will be taking your image. This is much more complicated then just pointing the camera and hoping for the best. The specific point of view is critical for your composition. It i this one and only point where your camera will be set before you press the button, this is the point from where all the elements are place in right position, where all the shapes and forms of threes, mountains, lakes, ocean, rocks are connected. It is very hard to find this point and you have to learn and practice before you will be able to find it fast and effective. but remember landscape photography is not about fast and rushing, if you think you like the pressure and rushing you should go into journalism or documentary photography.

Highlight Clipping
- check the histogram, check whether the area is too bright to right so that over-exposure?
- when viewing the photos in the camera, turn on the feature 'highlight clipping indicator' so that the white area that suffered washout will be marked by the camera in the form of blinking
- not all that bright areas of washout was considered failed, if the experience is not an object image washout important then just ignore it
- but when the light of the washout area is an important area in the photo, the photo needs to be repeated
- when the camera is often experienced clipping in high contrast areas, can lower the komponsasi exposure to -1 / 3 so that the images will be 1 / 3 stop darker (darker images will create more shadow detail in dark areas)
- certain cameras (like the EOS 550) had a highlight tone priority feature, the feature can be activated when we frequently shooting a white object in order to keep the details

Nikon D5100
Nikon D5100 is the latest series of the D5000 is the first Nikon digital SLR cameras with LCD screens folding.
A new feature in the D5100 is largely aimed at users who want to record video / movies with their DSLR. The camera is capable of capturing movies at a resolution of 1080p and 720p at 24 or 30 fps. LCD screen 3-inch size, with 921,000-dot density can be flipped out and tilted up to 170 degrees, which can be used in movie mode and Live View. Special Effect mode the camera gives users four filters that can be applied to the film and still images: Selective Color, Color Sketch, tilt-shift effect, and Night Vision, which increases the ISO to 102 400.
D5100 has the ability to auto focus on the continuous mode, a feature film which debuted in the D3100's. One of the known weaknesses of this feature is that it produces a loud noise being picked up by microphones on-camera. To help overcome this problem even with additional costs to consumers, Nikon released a new external microphone called the ME-1 which correspond to the camera hot shoe mount and plugs into the mic input port. It is designed to compensate for most of the noise created by the auto-focus lens. Microphone ME-1 will be sold separately starting in April at a price of $ 180.

Fashion Photography
Next vital thing which you keep in mind is about your subject. Shot the picture of your subjects from different angle with different poses. Also, plan before hand how you will capture the most important people of the day especially bride and groom. Also, try to cover some natural poses and never miss out to capture special moments of the day. Also, cover the location and choose a happy background with dark colour and a beautiful decoration to shot the pictures of bride and groom. Try to capture emotions in your photography.
Also, use two cameras for the day and make sure that both the cameras have different lens. Moreover, always keep your back-up that is extra equipment with you so that if in case there is problem in your camera you have another one. When taking group photo at the time of shooting wedding photography try to give the people your pose and make sure you focus on each and everybody in the group. Be creative enough to give unique and innovative poses in your group photography.

Natural Ligthing
A photographer has to understand the sun's color scale. Photographs make some viewer towards certain feelings, regularly warmer colors bring to mind more passion in photography lights. Thus to get the right time of the day you have to understand the suns affect on the colors. The suns evoke neutral colors in the noon hours, when closer to afternoon you will have redder color.
You should work with the angle and direction of the sunlight while exploiting natural light. The subjects or objects which are directly behind the sun will get too much light that means overexposure in photography lights. You will get softer shadows if the sunlight is wide and diffused while the more shadow you can make if the more narrow the light is focused. That is the way shadow is used, if used properly the shadow is able to give you more quality to the pictures.

"wildlife photography" |
The focal length of your lenses will establish from how far you can take a clear shot. Wildlife photography lenses with long focal length will allow you to take a clear shot when you are miles away. This is very important when you are taking shots of dangerous animals such as lions, elephants and snakes since you do not need to be next to the animal to take a shot. A lens with a focal length of 400mm and above, for instance, is perfect when you are taking photographs of birds or carnivores that can attack and injure you.
