Digital Camera Batteries – Excellent Power Source for Your Camera

Digital camera batteries are specifically designed for the unique way digital cameras use energy – in big power bursts. Digital camera batteries have substantial power with a much longer life than alkaline AAs.

Batteries for portable consumer devices are principally made using technologies such as:

- Nickel Cadmium (NiCd)
- Nickel Metal Hydride (NiMH)
- Lithium Ion (Li-Ion)

Each type has unique characteristics manufactured for different uses.

NiCd and NiMH:

The main difference between the two is the fact that NiMH (the newer of the two technologies) offer higher energy densities than NiCds. NiMH are less prone to problems and require less maintenance and care. NiMH are also more environmentally friendly than their NiCd counterparts, since they do not contain heavy metals(which present serious landfill problems).

Li-Ion:

Li-Ion produce the same energy as NiMH but weigh approximately 35% less. This is a definite consideration in portable devices where the battery makes up a significant portion of the device’s weight.

Another reason rechargeable Li-Ions have become so popular is that they do not suffer from memory effect at all. Memory effect is voltage depression caused by improper recharging.

They are also better for the environment because they don’t contain toxic materials such as Cadmium or Mercury.

Rechargeable digital camera batteries are rated in “mAh”. The mAh stands for Milliamp Hour, a technical term for how much power a particular battery will hold. Those with higher mAh values theoretically last longer without requiring a recharge, allowing you to take more photographs before you have to replace your cells.

It is recommended when installing batteries that their mAh values match. Otherwise, it is possible that one will drain before the others, causing extra strain on the others, or preventing further photo taking until all are replaced.

- Help and Tips

Cameras consume battery resources quickly, even rechargeable ones, so you should always carry extra. NiMH tend to last much longer than most standard alkaline AAs – plus, are rechargeable, so they can be re-used for quite a long time.

Turn off your digital camera when not in use. Don’t stop after taking every photo and look at the picture in playback mode. If you are using MicroDrive media, be forewarned that these miniature hard drives may take up quite a bit more power than Compact Flash cards.

Rechargeable batteries don’t stay charged forever. They tend to lose a little of their power every day. If you recharge often and frequently use your digital camera, you will probably never notice this loss. However, after a couple of weeks, the loss may be noticeable, and after a couple of months or longer of non-use, those once were ready-to-go but now may have lost enough power to make them unusable.

If you are not planning on using your digital camera for a while, it may be wise to take your batteries out for storage. This reduces the chance of chemical leakage and corrosion, which can seriously damage your equipment.

If you plan on taking photos in colder weather or snowstorm, note that batteries may hold their power for shorter periods of time than in warmer weather. You may either want to bring extra during your photo shoot or look for those specially rated to handle colder temperatures.

If it is raining, or if you are near an area of running water such as a waterfall, be extremely careful. Get at a safe distance from the water before you change out the power cells. Water can corrode, possibly causing leakage, and this can damage your equipment.

A question for Photo shop users, I am new to photoshop and digital photography I downloaded a few lynda

.Com videos on photoshop and I am amazed at what the program can do. However some of the terms they use I don’t really understand for example hue and saturation to me seems to be the same thing, I am probably wrong. Camera raw is another term I don’t really get, I checked the photoshop help and the definations they give is confusing to me, I guess because I am new. I checked on line and the one site defines the terms one way another site another way. Is there a site or resource where I find the definitions of the most commonly used terms in I guess you would call it photography or digital artistry? What I am asking is where can I find the definitions of these terms so I can fully understand what the instructors and other tutorials are trying to explain? Thanks

Hue is essentially color or color variation. Saturation you can think of as the richness of a color or the color density. You will see people refer to “highly saturated colors” meaning the colors are bright and strong and rich, sometimes almost unreal looking. Think of a newly opened red rose in bright noontime sunlight on a summer day. The red is very rich, very intense. That same red rose in the afternoon with shadows over it is still the same red, but not nearly as rich looking, so not nearly as saturated. In fact, you will run into the term “desaturate”: it means to pull color from an image. A completely desaturated image has no color, just shades of gray.

Many good quality digital SLR cameras (DSLR, SLR meaning Single Lens Reflex) can shoot in RAW. Unfortunately each camera company has a different RAW standard, which can make things confusing, and Adobe’s RAW in Photoshop is another standard. Luckily what Adobe has been doing is making its RAW interpreter, if you will, able to understand the RAW settings of many different camera companies. RAW is the raw information that the sensor on the camera records, with no compression. JPEG or .jpg files, the most common format and what all cameras can pretty much shoot in (from your very low end cell phone camera on up) are compressed files and automatically lose some information. This depends on the camera too. RAW files are everything, every bit of data that the camera’s sensor or sensors can pick up and record, it’s why they are HUGE files. You might see information that states your camera can shoot 10 RAW files on a 1 GB memory card, but can record 50 high quality large .jpg files.

Photoshop includes the ability to open edit with RAW; you can also then convert after editing to .jpg if you wish, and of course for printing, publishing, sending images via e-mail or uploading to a website, generally you will need to save your images as .jpgs. Do be aware that you don’t want to EDIT in the .jpg format. If you are editing an image in Photoshop, save the image as a Photoshop or .psd file format (.psd is the “native” Photoshop file type). The main reason, aside from being able to use all the tools, filters, etc in Photoshop is that the .jpg format is what is called “lossy.” Every time you open, edit, and resave a .jpg file, the compression algorithm it uses throws away data. So over time you will find a .jpg will lose quality. There’s nothing you can do about that: it’s built into the .jpg file type and it does this automatically.

You may want to invest in a couple of books. I think you probably don’t need the Photoshop for Dummies book (I am assuming you are using Photoshop CS3?), but you might want to look at the Photoshop CS3 Visual Quickstart Guide and the Photoshop CS3 Bible.

Hope that helps you!
