Guide To Digital Photography

Professional photographers know exactly what they’re looking for when they purchase a digital camera. Years of experience and fine tuning digital cameras every day makes the choice clear for them. For the rest of us, a new camera purchase can be a daunting experience. I know when I first got into digital cameras the technology seemed a little intimidating- but it doesn’t have to be. Here’s a short guide with ten things to look for when, as an amateur photographer, you’re ready to replace that antique sitting on the top shelf of the closet.

1. Resolution – When digital cameras first came out, it was all about the megapixels. There was a wide variety of sizes (and prices) available- however, now most of even the smallest digital cameras are 5 megapixels, which is more than adequate for your typical 4×6 vacation photos and the occasional 8×10. The time to go larger is when you want to regularly create larger pictures- or you want to be able to zoom in on areas of specific detail and print those. The compromise you must make for those larger pictures is more space used on your memory card, so if you get a higher megapixel camera, make sure to pick some extra cards.

2. Exposure control – For most amateurs, aperture size and shutter speeds are a mystery. What should I use when? The manufacturers have addressed this with scene preset modes. Picking the correct mode allows you to select the proper settings of, for example, a close-up by simply clicking ‘Macro Mode’ instead of manually configuring the camera. If you’re interested in digital cameras as a hobby, manual configuration options are something you should look for.

3. Zooms –There are two types of zoom available, optical zoom and digital. The one you should really pay attention to is optical zoom- pictures using optical zoom are sharper. Also understand that when the camera is using the higher magnification settings, it will be more vulnerable to shaking, so you may want to pick up a tripod if you’ll be using that zoom most of the time.

4. Size – Take a little time to think about what you’re going to be using your camera for. There’s always a tradeoff between size and functionality- here’s a quick summary:

a. Ultra Compact – small, light pocket sized cameras. Some may have fewer features.

b.Compact- fit in a modest camera case, great for point and shoot pictures.

c. Advanced- more functionality here along with more size. Typically we see buttons for modes as opposed to menus (which saves having to navigate), better zooms, and they also accept accessories (lenses, filters, etc.)

d. Digital Single Lens Reflex (DSLR) – Heavy and large, these offer the best functionality; typically professionals and serious photographers use them.

5. Weight – Hand in hand with size is camera weight. Generally speaking, more features equals more weight, so think carefully about what you really need. A small, light camera with fewer features is a better choice if you want to take it everywhere and get lots of pictures, as opposed to a heavy monster you dread having to lug and only use once in a while.

6. Batteries –Basically batteries come in two formats, proprietary battery packs, and then there are cameras that accept AA batteries. If you get a camera with the proprietary pack, it’s worth it to purchase another one as backup, because invariably you’ll want to take a picture and the battery will die. I recommend getting a camera that allows you to use AA batteries- if you need to buy a set in pinch you can, and you also have the flexibility of buying rechargeables and using them again and again.

7. Speed- When you are ready to purchase, be sure to check out the lag on button press. If you want to photograph things in motion (kids, pets, sports, etc) it can be very frustrating to try to snap that perfect picture and have the image captured 5 seconds later after the moment has passed. Some cameras offer continuous shutter mode, which allows you to snap pictures in sequence. For most amateurs 5 frames per second is adequate.

8. Manual Focus – part of the beauty of digital cameras is most of them take care of focusing for you. In some situations you may want the ability to manually focus to bring out detail.

9. Low Light Modes – Some cameras have auxiliary lights to help focus or even night vision mode. If you’re going to be taking pictures at night, it’s worth the money to add this to your checklist.

10. Accessories- Most people focus exclusively on the camera, and the accessories are an afterthought. Depending on where you buy your camera, you may be able to get a package deal that includes things you would have to buy anyway, like a case, memory cards, extra batteries and the like. If you buy your camera in a camera store don’t be afraid to negotiate, many will give you a better price or throw in extras like photography lessons.

When you buy a digital camera there’s no need to be intimidated, just do some research online and have an idea of what you want to do with your camera, create a list of important points, and then buy with confidence.

An electronics on-line discussion forum contains a story about an elderly woman who wanted a simple camera to take pictures of her grandchildren. When she received a digital camera for Christmas, she looked puzzled for a moment and then asked, “Where do you put in the film?” This humorous example demonstrates how the revolutionary technology of digital cameras may be mystifying for those who have difficulty grasping the concept of a “filmless” camera! For almost a century, photography enthusiasts sagely discussed such topics as 35mm film, light meters and F-stops; today, digital cameras have made such topics all but obsolete.

Howstuffworks.com contains an article by Gurevich, Karim, and Wilson that greatly simplifies an explanation of how digital cameras work. Very simply, they explain that CDs, mp3’s, and DVDs all share the same technology: they convert traditional analog “wave” data into digital data based upon “bits.” In so doing, this radical shift in technology has changed greatly – and forever – how we do things and what has become possible including digital “filmless” cameras. While film cameras depend upon chemical and mechanical processes, digital cameras contain a computer that records images electronically.

In 1994, Kodak and Apple developed and sold the first digital cameras. Today there are hundreds of models to choose from, depending upon the type of pictures you need, the complexity with which you’re comfortable, and what digital camera you can afford. For everyday use, most people prefer a “point and shoot” camera that isn’t complex, takes good quality pictures that can be loaded onto computers or printed for personal use and to send to friends, and is affordable. According to a number of consumer guides and customer reviews, the top ten digital cameras in the low, mid, and high price ranges are:

1. Nikon D300 (high)

2. Canon EOS 5D (high)

3. Canon EOS 40D (high)

4. HP Photosmart M547 (low, great value)

5. FujiFilm Finepix S700 (mid)

6. GE A730 (mid)

7. Nikon D200 (high)

8. Canon EOS Digital Rebel Xsi (high)

9. Panasonic Lumix DMC-FZ18 (mid)

10. Canon EOS 30D (high)

The point should be made that what constitutes a “great” digital camera is usually in the eye of the beholder. One person’s “top ten” list is almost certain to differ from another person’s. For example, a digital camera that is making devoted converts is the Casio Exilim series that sells in the mid-level price range, depending upon your digital camera photography needs. On the other end, Digital Camera.com rates the Pentax Optio E-10 as “the worst digital camera ever.”

With all these differing opinions, what’s the best way to buy the digital camera that’s right for you? If you simply want to take personal pictures, choose a digital camera that has at least three megapixels. This will give you good quality pictures at a very affordable price. Remember that the higher the number of megapixels, the better quality your pictures will be, but the digital camera you choose will be more complex and more expensive. Also consider the size and shape of the camera; is it easy for you to carry in your purse or pocket? Finally, be sure your digital camera has at least 256-512 megabites of space on its memory card so you won’t have to buy additional memory cards. Taking all these factors into consideration will help you enjoy capturing treasured memories for years to come.

Many digital cameras with upgraded technology are being introduced every day. This makes it more difficult to select a camera, as you are left with a wide range of models to choose from. However, most buyers have specific features and needs in mind. Rather than going for the latest model, buy digital cameras that best suit your requirements.
What should I look for when buying a digital camera?
The cheap camera lenses, resolution, display size, performance and battery life should all play a significant role in your buying decision. Here are some features to keep in mind while picking the right camera for yourself.
Resolution:
Resolution is typically defined as the number of pixels that make up a picture. A digital cameras resolution is closely related to image quality. You need a high resolution camera to shoot and print highly detailed photographs. If you want to enlarge and crop any of your photos without loss of clarity, go for cameras that offer a higher resolution. If you do not intend on printing your photographs and would rather email them to friends, a lower resolution camera would be a better choice. They are more affordable and still produce fairly good images.
Memory and Connectivity:
Generally, digital cameras have a removable storage option, such as a memory card slot. Digital cameras support a wide range of formats like flash memory, memory sticks, SecureDigital cards, SmartMedia cards and xD Picture cards. Many TVs, laptops, digital photo frames and some gaming consoles have memory card readers, so you can easily view photos that are stored on memory cards. If you want to save money, store photos on the cameras internal memory rather than on a memory card and transfer them to a PC or Mac using a USB cable. Digital memory is a huge time and money saver!
Batteries:
Rechargeable batteries are highly recommended because they can be charged and reused again. Recent cameras are compatible with NiCad, NiMH and lithium-ion batteries. Though NiCad and NiMH are inexpensive, lithium-ion is worth the extra money. They are long-lasting batteries with low self-discharge rates. You should opt for cameras that are compatible with lithium-ion batteries. A few cameras come with an AC power adapter that can be used to charge the digital camera battery as well.
Zoom:
Digital cameras come with two types of zoom lenses, optical and digital. Both of these zoom lenses allow you to take close-ups of a distant subject, although they accomplish this task through different means. The optical zoom magnifies the image before the shot is taken, whereas the digital zoom artificially magnifies the image by enlarging the pixel area but this leads to a loss of resolution. You should pay more attention to the optical zoom rather than the digital zoom when comparing models.
Modes:
Most cameras available today have preset modes for shooting images under different conditions. Factors such as exposure, aperture, focussing, light metering, white balance and sensitivity can all be adjusted. Many digital cameras also include video capture modes, enabling you to take short videos at different frame rate speeds.
ViewFinders and LCD Displays:
The optical viewfinder is the window you look through when taking a picutre. Although there are digital cameras with viewfinders, several of the latest models have only an LCD display. The LCD screen lets you view an image as you take it and also plays back pictures and videos saved on your camera. Anti-glare screens are best for buyers who plan on shooting a lot of photos outdoors. If you need a durable camera for rough use, opt for a scratch resistant screen.
Technology:
Digital cameras also come with innovative technologies that make photography fun and easy. Do u want to avoid overexposed or darkened faces, recognise multiple faces or optimize the color and tonal qualities of your photos? Not a problem. Todays cameras are well equipped with automatic red-eye and camera shake detection and correction as well as multiple face recognition. Not no meantion tons of
What are the different types of cameras and camera accessories online or available through conventional stores?
Point-and-Shoot Models:
Point-and-shoot cameras are a dime a dozen. These entry level models provide low resolution with little magnification. If you do not want to spend time on focusing and figuring out the settings and controls, a point-and-shoot camera is just the ticket. You will find plenty of these models that are low in cost and easy to use.
Intermediate Models:
These models are especially designed for beginners. Equipped with a range of automatic settings, these consumer-level digital cameras produce flawless pictures. They usually have a resolution of 3.2 to 5 megapixels and a 3:1 to 4:1 zoom lens.
Advanced Consumer Models:
If you have taken a class or photography is one of your hobbies, then you will probably want some additional features. Choose from the many advanced consumer models with higher resolutions, quality lenses and morer zoom. These models let you add features based on your needs and give you the freedom to personalize the settings.
Prosumer Models:
When you buy digital cameras, if consumer models are too basic for you and professional models are too complex, you will love a prosumer model. These sophisticated cameras have the best of both worlds. They have a vast number of options to work with, like switching between automatic and manual focus, selecting the shutter speed and adjusting the aperture settings. You will also have the opportunity to express your creative side by manipulating images. You can adjust the brightness and contrast levels for truly unique snaps. You can expect a minimum of 5 to 6 megapixels in this category. These digital cameras can take 2 to 3 pictures per second, but tend to be more fragile than other models.
Professional Models:
You will need a top of the line model that sports the latest features to meet your high demands, if you are a professional photographer. Professional models are capable of producing high resolution images with magnificent colors and clarity. They have interchangeable lenses and a resolution of up to 14 megapixels. These models are the fastest on the market, allowing you to take 5 pictures per second. Professional digital cameras have a whopping storage option of at least a 1 GB mini hard disk drive, on an average.
