Nikon Digital Camera Suggestions Nobody's Heard Of

Nikon digital camera suggestions might include a SLR digital camera or a compact point and shoot camera. The Nikon D3digital SLR camera is a nice little camera for the professional photographer. The body alone can cost about five thousand dollars and then you will need to buy the lenses, which could run you hundreds of dollars for just one. If you just need a camera for every day use, you might find the Coolpix digital cameras suited for your needs.

The Nikon digital camera suggestions for the Coolpix digital cameras include the P1500 and the S700. The P1500 has 12.1 megapixels, four times digital zoom and 3.5 optical zoom with a two and a half inch viewing screen. This is a great camera for the price. For a little less money, Nikon has the S700 with 12.1 megapixels with four times digital zoom and three times optical zoom with a 2.7 inch viewing screen. Both cameras are compact and easy to take anywhere you go. The ease of use is perfect for beginners as well as experts in photography.

The Coolpix S10 digital camera is unique with a movable viewing screen. This camera has 6 megapixels with ten times optical zoom and four times digital zoom. This would be the perfect camera for taking group pictures where the user wants to be included. The next of the Nikon digital camera suggestions would be the Coolpix S51. This little camera takes some clear images and has many features and accessories that you would need. The camera has 8.1 megapixels with four times digital zoom and three times optical zoom. The three-inch viewing screen makes seeing the subject easier.

Depending on what your need is Nikon has many different cameras that give clear and crisp images with perfect coloring. You can compare the cares to see which one will give you the most functions and features.

While Nikon is one of the best when it comes to high quality digital cameras, they're certainly not the only game in town. There are equal and better cameras around, you just need to know where to look.

All About Hard Drive Recovery Software - Things You Need to Know Before Buying a Hard Drive Recovery

Everyday, more than $2500.00 worth of valuable data is lost due to hard drive failures or crashes.

Top that off with the fact that more and more people are storing their important and confidential files on the computer, it's natural that data recovery companies pop up like mushrooms and offer data recovery options like hard drive recovery software and tools.

While this sounds great, the question: "What makes a good hard rive recovery software?" has to be answered.

But before that...

Why Freewares Don't Cut It

Some of you might argue - why buy when you could get it for free?

I do understand that we want practical solutions - money-saving and efficient at the same time. And what else could sound more practical than a free hard drive recovery software to retrieve your files?

I felt the same way until I found that most free data recovery tools out in the internet either have an evaluation period or very little support, which means you can only recover a handful of files.

And to those who're thinking about getting their hard drive recovery software through P2P, most downloads come along with a virus or malware that worsens the situation.

Now back on track, what should I look for in a data recovery tool?

Having a user-friendly hard drive recovery software is a good start. You sure don't want to shell out more hard-earned dollars just to get a technician to get the software up and running.

A data recovery software should come with an easy-to-follow interface that would allow you to retrieve your files in a few clicks of a mouse.

Another big factor you must take into account is - what file types does a hard drive recovery software support? Hard disk recovery tools aren't created equal. Some can recover file types which others can't.

Knowing which file system a hard drive recovery software can work with is also important. Very much like the case with file systems, different data recovery tools can recover data from the most common file systems like FAT, NTFS, Mac file systems, and more.

Keep in mind these handy tips about things to look for in a hard drive recovery software and, in no time, you'll have your data recovery tool that would keep your mind at peace against data loss.

Get A Hard Drive Recovery Software That's Easy To Use And Supports 300+ File Types And Works With Most Common File Systems...Recover Your Files In 4 Easy Steps!

How To Repair Dell E152Fpb LCD Monitor

The complaint for this DELL E152Fpb LCD Monitor was when switched on has power (LED lit) but no display. LCD Monitor is different from the CRT Monitor where you could feel the static at the front of the picture tube or hear the rushing sound from the high voltage produced by the flyback transformer. In LCD, if no display you won’t be able to know if the inverter board is working or not unless you use an oscilloscope to point near the inverter board and the scope could display a waveform indicating the inverter board is functioning.

A faulty main board may cause no display problem in LCD Monitor. If there is a problem in the main board, it would not send a “on” (enable) signal to the soft start circuit and no voltage will flow to the inverter IC thus no waveform produce by the high voltage transformer.

In the above case, after the cover was removed, the first thing I check was the vcc (supply voltage) to the inverter IC. This model is using the famous TL1451ACN Pulse width modulation (PWM) IC-some preferred to call it as inverter IC. Pin 9 is the VCC supply input and it should have about 12 Volts when the power is “on”. Measuring the pin with my faithful digital multimeter, it reads only about 3 volts which indicates there’s a problem in the supply line. It could be components that are faulty that dragged down the line or it could be the switch mode power supply itself that don’t produce enough power.

In order to find the answer as which section is giving problem, the first clue was that the power LED indicator lit and this prove that the IC is supplying enough power to the circuit. Another clue was that the meter is registering about 16 volts at the input of the 2A fuse. Because of these clear answers, we can conclude that the switch mode power supply is working fine. You can also use a 12 volt light bulb to confirm it. You may read my other post on LCD Monitor repair articles which talks about using 12 volt light bulb for troubleshooting purposes.

I kept on asking myself, why the voltage drop to 3 volts after the fuse. Before the fuse it reads about 16 volt but after the fuse it reads only 3 volts! I didn’t suspect the fuse, because the fuse can only either yes or no and no in between. The first circuit that I checked was the start circuit but all components checked to be okay. I even desoldered the pin 9 of TL1451ACN inverter IC just to make sure it is not this IC that pulled down the voltage.

This problem really challenges my troubleshooting and repairing skill, because almost all suspected components already checked to be working. Even the start circuit transistors (C945 & A733) I direct replaced, afraid they would breakdown when under load. The only component that I didn’t check was the fuse! By using my meter placed across the fuse, instead of getting low ohms or zero ohm reading I got 1.012 Kilo ohms! I‘ve got a surprised and don’t believe that a fuse can actually go into high ohms instead of open circuit. I always thought that a fuse is either close or open circuit. A fuse with zero ohms turned into high ohm thus the 16 volts dropped to 3 volts! I’ve came across lots of this type of fuse but this is the first time a fuse changed into high resistance.

Replacing the fuse only put the DELL E152Fpb LCD Monitor back to life. The lesson learned from here is that don’t assume that a component is always in a good working condition. You have to confirm it with your meter and if you still suspect the component is giving problem, simply replace it with a known good one and retest the equipment. Semiconductors can breakdown when under full operating voltage.

Digital SLR cameras body and lenses

By: Jacob Georgeson

Digital SLR cameras are usually sold in two parts: the camera body and lenses. There are many types of lenses with different characteristics from macro to zoom, with special options like image stabilizers, special filters and more. In this article you will read about some lenses options and what you should consider when buying them.
You can and should own more than one lens. Different lenses are better at different scenes. An obvious example is the difference between a macro lens used to take shots of objects from a very short distance sometimes almost touching the camera and zoom lenses designed to take photos from a far distance. Professional photographer always carry a few lenses with them and change the lens often in order to use the right one for each photo shot. Sometimes professional photographer actually carry a few cameras with different lenses mounted on them allowing them to quickly choose the perfect lens for each shot without the need to actually switch lenses back and forth.
Some lenses also provide special features that better the photos taken. For example image stabilization also known for short as IS eliminates the effect of small camera movements as the pictures is taken. Such movements are a problem in extreme cases for example when shutter speed is low in low light scenes or when using a high zoom lens taking photos from far away. In those cases every small camera movement translates to blurry digital photos. The image stabilizer (IS) is an optical electro-mechanical mechanism. Using a gyro and a floating optical element the image stabilizer senses camera movements and moves the optical element in right direction and distance to compensate for such movements.
If you need to take photos of objects from a very short distance you should consider purchasing macro lenses. Macro lenses enable the digital camera to be positioned very close to the object sometimes almost touching the object and still sharply focus on it. Common objects that photographers experiment with when using macro lenses are insects, leaves, screws, nails, bolts and more. Another challenge with macro photography is lighting. If you need to use a flash any normal flash would emit light that is too intense just because the object is closer to the camera than the focus was designed for. You can either use a flash that allows setting for such a distance or place a filter on the lens.
If you plan to use really long zoom lenses you should consider lenses that support special tripod mounts. Cameras with very long lenses are heavy and their gravity center shifts out toward the lens. In order to stabilize a camera with such lenses a special tripod attached to the lens is needed. When buying such lenses it is recommended to make sure that such a tripod can be used with the lens and if you already own a tripod that the mounting mechanism is compatible with the lens.
When buying lenses you should also take into consideration their planned usage. Tow lenses can have the same optical characteristics but for example very different weights just because they are made from different materials. If you plan to travel and carry the lens weight is important even at the cost of a higher lens price.
