Modern cameras are made to do everything on their own. With a self-timer, a camera can decide when it’s the right moment to freeze time capturing an image. Seriously, today’s cameras are incredibly smart. There has never been a time when getting into photography was so easy, that is assuming you can figure out what all the buttons, knobs, and levers on a new auto-everything camera do.
In some ways, older cameras were less frustrating to work with. New automatic cameras can be a challenge for anyone to figure out. It’s kind of like setting the clock on your DVD player. If you ever take time to learn the steps involved with the process, it’s not difficult. Automatic cameras can be intimidating at first, but they are a joy to use once you have mastered the controls.
The amount of automation found in a pocket camera varies from manufacturer to manufacturer. Price is also a factor in the amount of automatic functions a camera performs. I think automatic cameras are like computers; they’re fantastic when they work properly and a pain in the neck when they don’t.
I browsed through a sales flyer from a major discount chain store just a few minutes ago. For less than $100 you can buy a 35-mm point-and-shoot camera from a name-brand manufacturer. The camera has a built-in flash and it sets shutter speed automatically. For about the same price, you can get a different brand of 35-mm camera that offers a pop-up flash (to reduce the red-eye effect in portraits).
In fact, it is hard to find a point-and-shoot (PsS) without a built-in flash. The model I looked at has a medium-power, zoom, telephoto lens. There are even less expensive cameras available.
If you move up the purchase-price ladder, you can find cameras with built-in zoom lenses with ranges in the neighborhood of 38mm to 140mm. Some models will imprint your photos with a date and time stamp. Not many professional photographers use pocket cameras as their primary tools, but I know many who use them for quick shots that would evade typical professional equipment. Don’t be fooled by the Do-Little cameras, they can actually do quite a lot. For most people, any camera with a megapixel rating of at least 5 is fine for routine use.
What Could Go Wrong With Idiot-Proof Cameras?
If you think that nothing can go wrong with auto-everything cameras, you’re wrong. A lot can go wrong with any automatic camera. While most pocket cameras are simple to operate, they can produce some annoying problems for the people who use them. Let me explain.
Imagine that you are on your dream vacation. Part of your fantasy is to amass photographs that will help your memories live forever. You begin your journey, snapping pictures of once-in-a-lifetime scenes as you go. All of a sudden, you battery goes dead. You left your battery charger at home. Well, there goes the great photography outing.
Many photographers using direct-vision cameras obstruct their lenses accidently without knowing it until they check their photos. Since the viewfinder on this type of camera is offset from the lens, you can’t see if your camera strap or finger is in part of your picture.
Spare Battery
One of the most frequent problems with an automatic camera is not the camera’s fault. It is a dead of dying battery. Get a spare battery for your camera and like the credit card company says, “Never leave home without it!” Low battery power can cause a number of difficulties with an automatic camera. A dead battery can put the camera completely out of commission. Rotate batteries frequently when using or storing your camera in cold temperatures.
Red Eye
Even if you have never taken a single photograph, you’ve probably seen the handiwork of the red-eye monster in photos you have seen. This evil creature lives in the flash unit of many cameras. When an on-camera flash is used to take a portrait, it often taints the photography by turning the subject’s eyes bright red. Some pocket cameras offer a red-eye reduction system. Others incorporate a pop-up flash that can help to keep the monster caged. However, unless you move up to component systems where the flash you work with is offset to one side of the lens, you might meet the monster eye to eye, so to speak.
What is red eye? It is when the eyes of a subject are red in a photograph. The problem is caused by having a flash that is too close to your lens. It is a common problem with point-and-shoot cameras.
Auto Focus and Auto Flash
There is a difference between point-and-shoot cameras and auto-focus cameras. Point-and-shoot cameras have a set range in which objects appear to be in focus. Auto-focus lenses adjust their focus based on the location of a subject. As good as auto-focus lenses are, they can be fooled. As an example, if you were to take a family portrait, using a self-timer, you might find that part of your family was soft in terms of focus.
If you were all standing side by side, the auto-focus should work well. But, if some of the family is in front of the rest of the family, the auto-focus is likely to lock in on only some of the subjects. This results in a picture with some distortion in it.
Automatic, built-in flashes sound good on paper and in advertisements, but they can limit your creativity. They can also fail to meet their minimum requirements. The sensors that trigger an automatic flash can be fooled by light patterns. Let me give you an example.
Let’s say that your children have just been chosen to star in a school play. You want to capture the moment with your camera. Hastily, before the mood changes, you position your children in front of a window. There are no blinds or curtains, and natural light is flooding into the room, behind the kids. Quickly, you point and shoot on auto pilot. The flash doesn’t fire. You assume this means flash was not needed. After all, it’s supposed to fire when light levels are low. The natural light behind your children has just fooled the camera. When you review the picture taken, you will find that you have a nice, dark, silhouette of your kids. Their cheerful faces will be hidden in the dark exposure. Creative options for built-in auto-flashes are limited.
Sun Flare
Sun flare can be a nasty problem when using a pocket camera. You can overcome this by shielding the lens of your camera from the sun with your hand. But if you’re not careful, your hand will wind up in the picture. Since lens shades won’t work on flat-faced cameras, you have to protect the lens by some other means. The human hand is usually the most effective. If you don’t prevent stray light from shining on your lens, you will see bright spots that resemble stars or doughnuts on your finished prints.
The more automated your camera is, the higher the risk is that something will malfunction. This should not scare you away from the versatile, easy-to-use pocket cameras. If you stick with a major brand of camera, you should not experience many problems that are not associated with the operator of the tool. Keep fresh batteries in your camera. Use common sense on exposures, and choose your camera settings carefully. If you follow these simple instructions, your little black box should give you good pictures.

Electric Car Batteries: Benefits And Drawbacks
So you’re thinking of getting an electric car? Well, one of the first things you need to do before getting one is to learn a few basic things about these vehicles — especially with regards to how they run and where they get their power. And like all things electric, an electric car relies on an independent power source — the battery.
A normal car (powered by an internal combustion engine) only needs the battery to start the engine as well as run the air conditioning system and the car stereo. That isn’t the case with electric cars. In fact, the battery used in electric cars runs about everything. When electric cars were first introduced, the primary concern was (and still is) the quality and reliability of the electric car battery, i.e. how long can the battery last before it needs to be recharged. Fortunately, the last few decades has produced significant improvements on how electric car batteries are made. Now we already have nickel metal hydride (NiMH), lead-acid and lithium-ion (Li-ion) types that are rechargeable and readily available in the market.
Compared to normal car batteries, how do electric car batteries fare? Here’s a look at the benefits:
Cost-effectiveness. For five bucks worth of electricity, your electric car can run for more than 300 kilometers. Now if you do the math and compare that with your current gas costs and equivalent mileage, you’ll see that going electric can be quite economic in the long run.
Cleaner & Greener. Although you still need to burn fossil fuels in order to generate the electricity needed to recharge electric car batteries, the pollution produced is very minimal compared to the pollution caused by internal combustion engines. Plus, with better power generation sources like nuclear plants, the level of carbon emissions in the process of recharging becomes even lesser.
Re-usability. Electric car batteries can be reused and recycled. So you don’t need to worry about how you can dispose of your battery pack.
However, like any new technology, electric car batteries are not perfect. Here are the drawbacks:
They’re heavy. Because electric car batteries are designed to provide more power, they need to be connected to battery packs to ensure heavy duty performance. And these battery packs are not light. A batte
1000
ry pack can weigh as much as half a metric ton. But don’t worry, there’s hope — manufacturers are designing electric cars with lighter body frames to offset the battery’s weight.
Recharging time. Unfortunately, there’s no technology available yet for quicker and easier recharging. You still need several hours of downtime before your electric car can run again.
Maintenance. Electric car batteries are still uncommon, which means the number of service stations which can do repairs is still fairly limited, too. And since they’re quite fewer, maintenance costs might be a bit higher, too.
No doubt, electric car batteries are still a work in progress. It has its own set of limitations but there’s still plenty of room for improvement. But in a few years, the new generation of batteries will be lighter, more economical and most importantly, more powerful. That’s certainly a comforting thought.
