If you are interested in sharing your photos using e-mail and web, you must learn how to resize the photographs and reduce their resolution. This is important because large-size pictures take a long time to download. They block individual mailboxes and don’t fit properly on screens.

For instance, if you open a 3 megapixel image on an average computer screen, you will not be able to see all of it. You will have to scroll the picture sideways or downwards to look at the full image. The picture will also need a lot of time to send via e-mail. Further, it may block the e-mail box of your friend if he is using a small-memory e-mail service.

Your digital camera has image editing software with a resize function. It can reduce the width and height of the image. However, before you resize a picture, save an original copy of the image. This will enable you to use the picture on those occasions when you need high resolution photographs.

This may happen when you need to sell the pictures to magazines that are printed on high-quality, glossy paper, or to advertising agencies that bring out high-end brochures. They will not accept your downsized pictures.

You can resize photographs on your desktop by using Photoshop software. This is a very powerful photo editing tool, but it takes time to learn it fully. You may want a product that is easier to use. PhotoResizer is easy to use software that you can download for free, from ShowYourPhotos.com.

If you have a lot of photos that you want to share, you can use a web-based photo album and control access to it with a password. If you want someone to see an album, e-mail a link to them that allows them to access it. There is no need for attachments and no slow uploads or downloads.

For more control over your photos, you can maintain your photo albums at your own website. Hosting can cost as little as $50 a year. Some of the paid Web hosting services you can consider are Webshots, Pbase and Photosig.

You can also use an online printing service like Club Photo, which will keep your online photo album for $25 a year. It will also take orders for prints from people you allow to access your albums for a fee. Prints can also be ordered on cards, calendars, mugs, etc.

Selecting batteries for your digital camera is no easy task. Many digital cameras use four AA cells and can drain a set of alkaline cells in less than an hour of working. For example, Canon Powershot SX110IS digital camera draws about 210 mA of power to switch on. This rises to around 1.3A when the LCD becomes active and to 2.1 A when the camera is used to shoot pictures.

No wonder digital cameras need strong and powerful batteries. A popular battery to use is the Li-on (Lithium Ion) battery. It is a cell type battery that is light in weight but packs more power than most cell type batteries. It needs little maintenance, is easily available and can be stored for long periods of time. The only disadvantage is the price. It costs much more than conventional batteries due to its sophisticated design and technology.

Another battery which is widely used in digital cameras and laptop computers is NiMH (Nickel Metal Hydride) battery. The big advantage of these batteries is that they do not cost much and are available in most stores across the nation. However, they need more maintenance and care and suffer from memory effect too.

The digital camera users can also use NiCAD (Nickel cadmium) batteries. These batteries can handle high power loads and were particularly popular with users of laptops and other electronic devices at one point of time. However, they are no longer as popular now, largely on account of the lithium ion batteries which are becoming the first choice of most digital camera users.

An important point to keep in mind while selecting batteries is their life. It always makes sense to buy batteries that are rechargeable. By doing so, the user does not have to worry about a failed battery in the middle of a shoot. He can always put the drained battery in a charger and continue shooting with a spare battery. This may not happen with a use and throw away battery. The user may then be stuck with a camera that does not work as it does not have a power source!

The selection of batteries for digital cameras also depends on charging techniques. For instance, in some cameras the batteries need not be removed from the body but can be recharged with the help of an AC adapter. When using such cameras it is always important to use a battery that does not leak.
