The Sony Cybershot DSC W270 is a mid range digital camera. This is true both in terms of features and also in terms of price. At around 27mm wide by my measurements there are a lot of smaller cameras out there and while the Cybershot DSC W270 will fit into larger pockets it looks noticeably larger than the more slimline models.

When it comes to features this is a point and shoot camera, but it does have one or two extra controls that set it apart from cameras at the cheaper end of the market. There are plenty of megapixels, with 12 squeezed onto the sensor. In fact if you blow photos up to a very large size you begin to notice one or two grainy sections creeping into the shots and you wonder if Sony has been a bit ambitious trying to fit so many pixels into such a small space.

The lens offers 5x zoom and has wide angle capabilities. One advantage of the extra megapixels is that extra zoom becomes available to you if you reduce the resolution (number of megapixels) you are shooting at. If you do this you get the added benefit of being able to fit more images onto your memory card. Don’t forget that 3 or 4 megapixels is plenty if all you are looking to do is make 6 x 4 inch prints of your photos.

One downside I often see of a wide angle lens is a loss of picture sharpness when the zoom is not being used at all. This is true of the Cybershot DSC W270. For snapshot sized prints this should not prove to be much of a problem as the loss of sharpness only starts to become apparent as you increase print size.

As is becoming more prevalent Sony has included a High Definition movie mode. This is handy if you like to take the odd video clip with your digital camera, but be aware the quality of the footage and the audio does not measure up to better quality camcorders.

In case you have a problem holding the camera rock steady when taking a shot Sony has built in image stabilisation. The LCD screen is 2.7 inches in size. For close up work the minimum focusing distance is 10cm. The majority of digital cameras can focus from closer in than this, so if you are planning to really get in close for a number of shots you may well find this proves to be a drawback.

To my mind features such as face detection and intelligent auto do not offer that much more than the automatic mode you find on most cameras. Still anything that gives a small improvement in the quality of your photos is worth having on board. There is a smile shutter mode too. When you turn on this feature the Cybershot DSC W270 will automatically fire off a shot if it notices someone is smiling. Only you can tell how much use you are likely to get from this feature. Of more use to you may be the ability to adjust the power of the flash unit if you feel an extra boost is required from time to time.

When it comes to picture quality the Sony Cybershot DSC W270 lacks a bit of razzmatazz, but then again it is only a snapshot camera and if you are that worried about picture quality then be prepared to pay substantially more and upgrade to a better lens and a greater array of manual exposure controls. In my view there are better compact cameras around, but there is nothing especially wrong with this camera.

Memories are created just about anywhere. And when I say anywhere, I mean that memories are even created underwater – so the creation of underwater digital camera.

An underwater digital camera is not just used to capture underwater memories; some professional marine photographers also use underwater digital cameras in their business. Even marine biologists and scientists use underwater digital cameras to capture marine life and thus be able to study the life and properties of the marine life. But I think it is safe to assume that you, my reader, are neither a marine scientist nor a professional photographer. Like me, you are just some photo junkie who wants to capture underwater moments and just cant figure out how without ruining your cameras.

Please listen to me when I say that even waterproof cameras cannot withstand underwater photography. To be waterproof is to resist the water in certain levels, submerging in under the water to get the perfect shot is like throwing it out of the window expecting a pick-up truck to pass by and run over it.

Now if you’re really serious about using an underwater digital camera to capture those wacky and funny moments underwater, I suggest that you buy specialty cameras.

There are rarely underwater digital cameras, as cameras are electronic and cannot withstand water and water pressure. The closest electronics has ever got to producing underwater digital cameras are producing underwater casings for digital cameras. These casing will turn your conventional digital camera into an underwater digital camera.

If you are shooting with your underwater digital camera, you need to take note of a few things to help you come up with the best images underwater.

Remember that as you farther under water, light diffuses. This means that your underwater digital camera will produce images darker than those images you took while on land – this is because of the light diffusion the red spectrum seems darker. To avoid this, use white balance come up with natural colors. Also, pictures taken underwater will come up larger than pictures taken on land with the same zoom effect. Be sure to check your underwater digital camera’s viewfinder to check the right picture angle and size that you want.

An underwater digital camera with its built-in flash will produce marine show phenomenon. It is a phenomenon wherein your pictures come out as blurry and with white particles floating above it, to avoid this phenomenon it is advisable to use external flash for your underwater digital camera.

Before using your underwater digital camera, submerge the camera in the water first for several seconds then check if there are leaks through the case. Make sure that no grain of sand or piece of hair is stuck in between the seal to make sure that water will not permeate the case and thus wet your camera in the process. It is also advisable to put silica gel or two inside the case of your underwater digital camera as long as they don’t disturb the camera’s operation. (Silica gel will keep the moisture from forming inside your camera case.)

Most underwater digital cameras come with optional lenses. Don’t be afraid to add these lenses to your underwater digital camera kit. Macro lenses will help you capture small things without getting too close and startling your subject.

Also, remember to always wash of salt when you’ve used it under salt water. If the salts are not washed off, in time they will crystallize; act as sands and cause leaks for your camera case. In cases when sands seem to get into the case, they are better washed off with streams of water.

Check out Sony, Nikon and Canon’s website for available underwater cases for your digital cameras.

When planning to buy a camera, it is best if you know the various kinds of camera on the market. This will save you time and money as well as mental strain from buying the wrong one and having to return it for replacement.

There are no exact rules in buying a camera, but be sure that the camera you buy does the job you intended it for. You should have a first hand knowledge, or at least some basic ideas about cameras.

Here are the different kinds of cameras:

The point and shoot camera:

This camera is popular among many because of its simplicity. There’s no need to worry about the control over exposure and focus. This camera allows you to just point and push a button to take pictures.

SLR camera:

SLR camera – SLR means ‘Single Lens Reflex.’ With an SLR, instead of looking through a separate window as your viewfinder, you actually look through the lens of the camera itself. This is one of the most preferred cameras for professional photographers.

Medium and large format camera:

The medium and large camera appeals to more of a perfectionist photographer who seeks more flexibility and clarity. Medium and large format cameras use much larger sized films than SLR.

Digital camera:

These are the most advance in camera technology. Digital cameras don’t use films but instead pictures are stored through the use of computer memory. You can transfer such pictures to your computer and send it via email. However, digital cameras tend to have a slight delay when you push the button to take a picture and you will need a good printer in order to print a quality picture.

Brand, model, and price range:

Among the famous brands of cameras are: Canon, Nikon, Pentax, Minolta, and Kodak, all of them have are known for high quality, when it comes to camera technology. Point and shoot cameras range from less than $100 to $1000. SLR cameras range from $400 to over $3000. Medium and large format cameras prices start from $2000 to $5500. While Digital cameras range from $500 up to $5000 for more advance features.

Tips on choosing the best camera, particularly a digital camera, without overspending:

1. Do your homework and familiarize yourself with the use of the camera before going to the store. Knowing how frequently you you will be using the camera and what kind of pictures you intend to take, will help a lot.

2. Be careful in considering added features, you may not need them anyway. Depending on your experience as a photographer, you will know which features will work best for you. If you’re a newbie, standard features will do.

3. More control may cost you more, so think about those extra features – if they are worth it or if you can afford them.

4. If you are planning to get a digital camera, remember that mega pixels do not necessarily dictate the clarity of your pictures. It still helps to know the how-to’s of taking the best pictures instead of just relying on the camera’s features.

5. When buying digital cameras, concentrate on optical zoom, not digital zoom.

6. Make sure the camera you are considering is compatible with your computer.

Is the Panasonic Lumix DMC-FZ38 the best choice of big zoom/bridge camera in its price range?

Panasonic Lumix DMC-FZ38: http://www.panasonic.co.uk/html/en_GB/Products/LUMIX+Digital+Cameras/Super+Zoom/DMC-FZ38/Overview/2718819/index.html
A big zoom, yet compact enough to carry around all the time – that’s the reason why I like the idea of only having 400g to carry. It would be used for aviation photography mainly, if that helps – although I would use it generally as well since I do not own a compact.

I would recommend it.Panasonic Lumix DMC-FZ38 is one of the best super zoom camera.Excellent picture quality.
