As a hobby photography has universal appeal and most people almost always have indulged in it. Occasions are not complete without photographs being taken to capture the essence of the event and make it more memorable. Pictures provide a record of what happened, when it happened and sometimes how it happened. You can always look back in time when you look at pictures taken long ago and they make for a historical and pictorial record of times past. Nowadays almost everybody has a camera, whether it is a modern digital one or an old-fashioned film camera. Many people have more than one, especially since mobile phones not come equipped with cameras. Photography equipment is not anymore the perquisite of the rich alone, it is now highly affordable and you get so much variety of photography equipment that you are spoilt for choice.
In case you are really taken up by photography and your skills are well honed, you may decide to buy more specialized photography equipment which will help you in your artistic endeavors.
What Photography Equipment You Require
Apart from your camera, which should be good, other photography equipment can also be purchased. The camera itself should have a good lens. You might want to buy something which is inexpensive, and there are many in the low-price range, or you may want to go in for a high end product. High end photography equipment is expensive, but you may want to buy it if you want to become a skilled photographer. If you are keen on taking photographs and making photography your hobby, do not hesitate to buy good quality photography equipment. Cameras can last a lifetime and also provide timeless memories. If your basic photography equipment is good, you know that you will find it difficult to go wrong when you take picture.
If You Want More Than A Camera When You Purchase Photography Equipment
Perhaps you want to buy everything you may need altogether. Apart from the camera, you can go in for good light equipment. Among the photography equipment which will be useful to you apart from a good light system, would be a tripod for still shots – it will steady and center the camera. A camera bag is another piece of photography equipment which will protect your precious camera from scratches and breakages. While these peripherals may not be essential, your picture taking abilities will definitely be enhanced if you use these items. Your basic picture quality will be higher than if you use a cheap camera with no peripherals.
From Where Can You Buy Your Photography Equipment?
Fortunately, photography equipment can now be purchased from almost anywhere, from your supermarket or an electronic shop or a special photography shop. You will probably be able to purchase most of your photography equipment at one go. But before venturing out to buy, arm yourself with the knowledge as to what you want, what are the good brands available and how much you want to spend. You can always check out reviews and get advice from friends and colleagues as to what you should buy before you buy it. Article Source: http://www.BharatBhasha.com

Take Better Digital Photos By Understanding Your Camera's ISO Settings
By Jeff Galbraith
What does ISO stand for, you ask? ISO stands for International Standards Organization, which refers to the group that set the standards for film speed. Luckily, this doesn’t have anything to do with what you need to know about ISO.
ISO, as it relates to digital photography, is an indicator of how sensitive to light your camera’s sensor is, and most digital cameras allow you to adjust this sensitivity. The majority of low to mid-range digital cameras have an ISO range that goes from somewhere in the neighborhood of 50 or 100 up to around 400 to 800. The lower the ISO number, the more light that is necessary to get proper exposure on a given shot.
So why not crank the ISO setting all the way up to the max and be done with it? Although this would allow you to get good exposure even in low light situations, there is a catch. The higher you set the ISO, the more “noise” there will be, causing your pictures to come out grainy looking. FYI, the camera’s “auto” setting doesn’t always choose the lowest ISO possible.
These days a good number of digital cameras employ some form of noise reduction at higher ISO settings. Unfortunately digital noise reduction is accomplished by applying a slight amount of blur to the image, which not only blurs out some of the noise, but also blurs out some of the fine detail.
All things considered, the best way to approach ISO is to use the lowest possible setting, but don’t over do it—using too low an ISO setting can result in blurry images caused by “camera shake”.
Assuming that you are using a camera with an ISO range of 50 to 400, here are some rule of thumb examples:
When shooting outside on a bright sunny day, use the lowest setting (ISO 50). On a heavily overcast day, or when shooting in heavy shade, use the next higher setting (ISO 100). When shooting in the early morning or late evening, use the next higher setting (ISO 200). If shooting at dusk or dawn, you would need to use your highest setting (ISO 400).
However, there is a way to avoid using your higher ISO settings, even in low light—its called a tripod. This three-legged wonder allows you to keep your camera perfectly steady, which eliminates the blurry images caused by camera shake.
Another option to keep your camera steady during low light shots is to set your camera on a stationary object (like a rock or the hood of your car) and use the self-timer. This feature allows a few seconds lag between the time you press the shutter button and when the camera takes the picture.
Remember, keeping those ISO settings as low as you can, will give you clearer, cleaner photos.

How does a digital camera passive auto focus work
By: Ziv Haparnas
In focus objects in a digital photo is a very basic requirement for high quality photography. There are two different ways to focus on such objects: manual or automatic. There are a few automatic focus methods one of them is known as passive auto focus.
High quality sharp and crisp digital photos are a result of many optical parameters that need to be set right. One of the most important optical parameters is focus. When objects in a digital photo are out of focus they look blurry and are missing details and clarity. When objects are in focus they look sharp and crisp.
While focus can be set manually by the photographer in most cases using the digital camera’s automatic focus feature is much easier and faster. There are many different algorithms and methods that digital cameras use in order to automatically determine the right focus for a specific scenario. One of those methods is knows as passive auto focus.
Passive auto focus
In many ways the passive auto focus imitates the way in which we set the focus manually. The digital camera defines one or more regions in the picture to focus on. These areas are usually around the center of the photo and are marked as rectangles on the viewfinder or the LCD. The digital camera then analyzes the captured picture seen through those regions.
The digital camera has a built-in computer chip that can run image processing algorithms. The camera executes such image processing algorithms to determine a Focus Level number. The exact way in which such a number is calculated is out of the scope of this article. A very simplistic explanation is that the digital camera transforms the digital image to a frequency space and measures the amount of high frequencies in the photo (high frequency in an image correlates to high contrast or to focus). The more high frequencies present the more in focus an image is and the higher the Focus Level number is.
The digital camera goal is to maximize the Focus Level number. In this way the digital camera achieves the best possible focus (or at least theoretically achieves such a focus). The digital camera does that by moving its lenses back and forth as it recalculates the Focus Level number. The camera is searching for a position where the Focus Level number is the highest.
When such a position is found the digital camera compares the Focus Level number to a predetermined threshold. If it is higher the digital camera announces a successful focus (usually by coloring the focused areas in green). If it is lower the digital camera announces a failure (usually by coloring the non-focused areas in red).
The passive auto focus method is relatively cheap to implement as it does not require extra sensors (such as distance sensors for active focus solutions). However passive auto focus can also fail. The reasons can vary: poor lighting conditions, low contrast objects that are hard to focus on like walls or solid surfaces and others.
When the auto focus fails you can either try to focus on other objects in the same distance from the digital camera, lock the focus and pan back to the original objects you wanted to capture or you can revert to old fashion manual focus.

Seven common mistakes when taking digital photos

By: Ziv Haparnas
You have probably taken photos before just to find out later that they did not come out as expected. Although digital cameras are getting smarter there are still a lot of decisions that the photographer has to make. There are also many mistakes that the photographer can make. Here are seven common ones.
Many mistakes can ruin a photo. Here is a list of seven common ones. The first step to avoid these is to understand what they are and why they ruin a photo. The second step is to be aware of them when shooting your photos.
Out of focus: An out of focus photo looks blurry and has low contrast. Usually such a photo is useless and can not be corrected. Most digital cameras can automatically set the focus for you and in most cases they choose the right focus for the scene. Some scenes however are harder to focus on and can fool the camera's auto focus mechanism. If you are using an SLR camera you can make sure that the objects are in focus by looking through the viewfinder. Most cameras sound a short beep when the focus is locked and also display a green rectangle around the area that they focused on. Always make sure that this area is where the objects that you care about are. For example if there are two objects in the scene in different distances from the camera make sure that the camera focused on the object you want.
Blurry photos: Blurry photos are most likely the result of camera shakes. Learn how to hold your camera to minimize shaking: it should be held firmly with two hands and it should "touch" your face. If you are shooting photos using slow shutter speeds you should use a sturdy tripod to prevent shaking. If you can not guarantee that the camera will be stable for example if you are shooting while you're moving set the camera to shutter priority and choose a fast shutter speed (assuming of course that the light conditions allow such setting) for example setting the shutter speed to anything faster than 1/250 of a second will most likely guarantee a non blurry photo even if the camera shakes a bit.
Underexposed: Photos that are underexposed look dark and lack details. The reason for underexposed photos is setting the exposure too low. Although the camera can measure ambient light and make the exposure decisions for you it can be confused by more complicated scenes. For example if there is a very bright light source in the photo it can confuse the camera to believe that there is enough light in the scene for a low exposure setting. The result will be a photo that captures the bright area but darkens all the others. Usually you can assume that scenes that have extreme lighting gaps between different areas confuse the camera for example if a quarter of the photo is very bright and the rest is very dark the camera is likely to set the wrong exposure. In such cases you can manually correct the exposure.
Overexposed: Photos that are overexposed have blown out areas and sometimes are completely saturated and white. The reasons for overexposed photos are similar to underexposed ones. The camera makes an exposure decision that is incorrect due to complicated scene conditions. In such scenes you can manually correct the exposure.
Shaded objects: A good example of shaded objects is when taking a portrait photo in daylight. The camera measures enough ambient light to set a low exposure value. Although there is enough ambient light shades can appear on the object depending on the angle of the light source relative to the object. For example if the objects face is lit from the side the objects nose can create shades. Or maybe if the object is wearing a hat and is lit from above the hat can create shades on the objects face. The camera can not automatically correct such shades. By understanding what causes shades you can easily eliminate them by turning on the fill-in flash. Firing the fill-in flash (make sure that the object is within flash range) will remove the shades from the object.
Red eye: This is a very common phenomenon. When taking photos of people or animals using a flash in a dark environment the eyes have some red glow in them. There are a few things that you can do to prevent red-eyes: some cameras support a "red eye reduction" mode. In that mode the camera fires the flash a few times before taking the photo. Although this can help reducing red-eye it can also result in photos of people with their eyes closed (as they are blinded by the pre-flash their reflex is to close their eyes). Other ways to prevent red-eye is to use bounce flash (you can do that with special equipment or for example by pointing the flash to a white wall) and using more ambient light if possible (for example by turning on all the lights in the room). Some cameras include built-in image processing software that automatically removes red-eye from the photos or alternatively you can use many software packages on your home computer to accomplish the same.
Dark Silhouettes: When taking photos with a bright light source behind the object (for example when the sun is behind the object) the result will be a silhouette of the object. One example is taking a photo of someone on the beach against a sunset. The result will be a dark silhouette of the person with a good photo of the sunset background. This problem can be solved using a fill-in flash. The fill-in flash lights the object making sure that it is captured with all its details. Simply remember to use a fill-in flash when taking pictures of objects with a bright light source behind them. One limitation is that the objects must be within the flash range otherwise the flash is useless and they will appear as silhouettes in the photo.

Digital camera modes shutter aperture priority and more

By: Ziv Haparnas
Digital cameras can be put in different photo shooting modes. The most used mode is automatic - the only thing you need to do is point and shoot. However understanding and using the other options will allow you to get better photos in certain scenarios. Here is how.
We will go over the various camera modes. Some modes might not be available on your camera. You can set the mode either by using the camera menus on its LCD in which case you can read and choose the mode by its name or you can set it by rotating a dial in which case you choose the mode by its visual icon. Spend some time learning the icons your camera dial uses - some are simple to remember (like A for Aperture priority and S for Shutter priority) others can be confusing.
Automatic mode This is the simplest mode and is also sometimes known as Program Shooting. In this mode the camera does everything for you it sets the shutter speed, aperture, focus and fires the flash if needed. This mode is the easiest to use and is good if you have to capture an event and have no time to play with the settings. It is also a good starting point for amateurs and a good choice if you just want to capture a moment or an experience and do not care so much about the fine photographic qualities of the photo.
Aperture priority in this mode you manually set the aperture value. The camera automatically takes care of everything else for you for example setting the optimal shutter speed for the aperture you chose. There are physical limitations and not every aperture value that you choose can be accompanied by other settings that will result in a good photo. The camera will let you know by flashing a green LED or in another way if it found the optimal settings that work with your chosen aperture value. One of the most common usages of this mode is when you need a narrow depth of field. By decreasing the aperture f-number the depth of field gets narrower. A narrow depth of field results in a photo that is focused on a specific object at a specific distance while the background is blurred. This is commonly used for example when taking portrait photos.
Shutter priority in this mode you manually set the shutter speed. The camera automatically takes care of everything else for you for example setting the optimal aperture value for the shutter speed you chose. There are physical limitations and not every shutter speed that you choose can be accompanied by other settings that will result in a good photo. The camera will let you know by flashing a green LED or in another way if it found the optimal settings that work with your chosen shutter speed. Using this mode is useful if you need to capture fast moving object or want to freeze the scene by setting the shutter to high speed. In other scenarios if you want to capture the feeling of motion in the photo a slow shutter speed would do the trick. For example when taking photos of water setting the shutter to relatively slow speed blurs the water and captures its movement making the photo more alive.
Manual mode In this mode you can set both the aperture and the shutter speed to whatever value you want. It gives you the most flexibility in shooting the photo but it is also harder to use. Although the camera does not set the values for you most cameras will still let you know if the values you chose are good or not for the photo you are shooting.
Portrait mode This mode optimizes the camera settings for portrait photos. The camera sets the aperture to a low f-number and the shutter to high speed in order to shoot with a narrow depth of field resulting in a focused object and blurred background. Portrait mode should be used in a well lit environment such as outdoor daylight or a well lit studio. It is better not to use this mode with a flash.
Landscape mode This mode optimizes the camera settings for landscape photos. White balance is set for natural sun light and the depth of field is deep allowing to capture objects at great distances.
Macro mode This mode is used when taking extreme close-up photos. How close you can get to the object depends on the lenses you use.
Sport mode In this mode you can take photos of high speed object such as runners or cars in a car race. The shutter is set to high speed to capture the object without blurring it and the auto focus is usually set to continuous to allow focusing on the moving object.
Night mode The camera optimizes the settings for night photos. Usually when taking night photos in other modes the result is a black photo and some scattered dots of light. In night mode the photo will include more details of less lit objects. Since night mode uses very slow shutter speeds the camera needs to be stabilized either on a stable surface or using a tripod.
In conclusion take advantage of the fact that taking extra digital photos is free. There is no added cost in taking more photos. Experiment with different photo shooting modes and learn which one works best in which scenario. You will quickly find yourself naturally changing the camera modes to accommodate different conditions.

Understanding Digital Camera Zoom Lenses

Photo by Pixeleye
By Michael HuddlestonThere are two types of zooms used with digital cameras: optical and digital.
Optical Zoom
An optical zoom changes magnification by moving glass in the lens, changing the image falling on the sensor. Using an optical zoom maintains picture quality.
Zoom Ranges and 35mm Equivalents
Optical zoom lenses usually have a specification called “equivalent in 35mm.” This tells you the zoom range of the digital camera compared to a 35mm film camera. Typical 35mm equivalent zoom ranges you will see listed are 35mm-70mm or 35mm-105mm.
For example:
Wide-angle means a lens takes in more than normal viewing perspective. Telephoto lenses magnify the subject, bring it closer. Using these numbers as a guide, you can get an idea of the range of zoom lenses and what they will do for you.
28mm…..wide angle
35mm……slight wide angle
50mm…..normal perspective
70mm…..slight telephoto
105mm…..moderate telephoto
135mm…..strong telephoto
200mm+…..extreme telephoto So, a 35mm-105mm equivalent zoom lens changes from a slight wide angle to a moderate telephoto. A 28mm-200mm equivalent lens changes from a wide angle to an extreme telephoto.
A 35mm-105mm equivalent zoom is adequate for most users. If you plan on doing landscapes or picture taking in small, confined areas, consider a camera that can zoom to a 28mm equivalent.
Optical Zoom as 2x, 3x, 5x…
Taking the 35mm-105mm example above, we divide 105 by 35 to get a 3x zoom. A 28mm-105mm would be approximately a 4x zoom, and a 35mm-350mm would be a 10x zoom.
Digital Zoom
A digital zoom does not change, magnification. It simply crops the image on the sensor to magnify the image. Because less sensor is used, you use fewer pixels. This decreases picture quality. When comparing cameras, always use the optical number as this is much more important. You can get the same effect as a digital zoom by using software to crop the photos.
Note About Digital Zoom
As digital cameras become more sophisticated and powerful they are becoming capable of delivering “optical tricks” that render pictures that are remarkably stable and good looking. Only recently, cameras “digital zooms” are getting much better. Like all things though some companies are better than others. Do your research.

Buying A Digital Camera? Five Things To Consider

By John Steele
When considering the purchase your first digital camera you will discover that today's cameras contain a vast array of advanced features. Probably most of them will be features you're not familiar with, and by the time you finish reading this article, the manufacturers will have added a dozen new ones.
Spare Batteries / Recharger
Filters and Lens Caps
External Flash
Memory Cards
Tripod
Photo Editing Software
Camera Case
Of course digital cameras are far more complex than what has been discussed in this article, and it's too easy to make a bad decision when buying online. That's why it's so important to get the feel of a camera before you buy it.
If you do find a camera you like and decide to buy it online, one a word of caution. Make sure you specify the little things like model number, warranty, place and date of manufacture, color, accessories, and so forth. It's easy to end up with a camera or lens you didn't want when buying from a vendor in another place. There are a lot of subtle variations in camera equipment. Be sure you know exactly what you're ordering and the return policy.

Digital Camera - Mode Setting Control

By John Steele
Most digital cameras today have a mode setting knob. It's probably the most important control on your camera. The nice thing about the mode setting knob is that you can set it on full automatic and forget it. When the camera is in full automatic it does four things for you; it will:
1. Focus the Lens
2. Set the Aperture (size of the lens opening)
3. Meter the Light and Distance
4. Set the Shutter Speed
All you need to do is snap the picture and you will get a decent exposure. But if we take a closer look at the mode setting knob we'll see it has other features as well. The typical digital camera will have the following settings on its mode knob.
Landscape: The landscape icon usually looks like a mountain with a cloud over it. This setting presets the camera with a small aperture and helps keep your image in focus. It also sets the shutter speed fast enough to eliminate a blurred image. This setting can also be used for night landscapes, though it is not the preferred method. As you become more proficient with your camera you will learn ways to customize the settings to get better low light photos.
Sports Setting: This icon typically looks like a figure running. It locks in a faster shutter speed to freeze the subject and background. The camera will use the center of the viewfinder for focusing.
Portraits: This icon is easy to find it usually looks like a persons profile. This setting opens the aperture for a shorter depth of field. It keeps your subject in focus, but blurs the background for a more pleasing composition.
Night Portraits: In this zone the icon usually has a star or moon in it. When shooting in this mode the flash mechanism fires to fill the background and correctly illuminate the subject. The night setting can be used when shooting in very low light conditions.
Close-up: The close-up icon often looks like a flower, usually a tulip. This setting is used when you want to take pictures with great detail like plants or insects. This area of photography is often called macro-photography and is an art form in itself.
Think of the different basic zone modes as tools to be used in different picture taking situations as they arise. You will get average pictures with the automatic settings. Some of them will be quite good. But the better cameras contain advanced settings sometimes referred to as Creative Zone Settings. These controls give you much more creativity in the pictures you take, and can be used to provide greater adaptability as changing circumstances arise. http://www.digital-id.info/
