About Photo Printers

If you plan to print the pictures you shoot with your digital camera, it's worth the extra few dollars to buy a photo printer. Determining which printers you look at are photo printers is usually pretty easy: the manufacturers usually put the word “photo” in the product's name or description.

Most photo printers are of the inkjet variety – the predominant consumer printing technology. Photo printers often print with smaller “dots” – the droplets of ink that help give inkjet s their name – than plain text printers. And many come with more colors of ink. High-end inkjet photo printers from some manufacturers now come with eight or nine colors of ink.

Color laser printers are also available, though they're much more expensive than many inkjets. A third type of printer is the dye sublimation printer, which uses heat to transfer dyes directly onto the media (paper).

If you print mostly 4” x 6” prints and durability and color are very important to you, consider a dye sublimation printer. Dye sub photo printers use thermal transfer technology to produce prints with a range of colors that's impossible for inkjet printers to match. Three colors are transferred separately to the paper from a plastic film. Temperature variations are used to produce up to 256 shades of each color. Finally a protective laminate layer overlays the entire print.

Dye sublimation technology has two drawbacks, though. First, you can't reasonably use a dye sub photo printer for text, as you could an inkjet photo printer. And, second, the majority of available dye sub printers make prints no larger than 4” x 6”. A few also produce 6” x 8” prints.

HP Conquers Inkjet B&W Issue

Until recently, black and white prints from inkjet printers were famously poor. Most consumer-level printers traditionally produced s B&W prints with definite color tinges. Inkjets could make a nice sepia-tone print, but B&W was a nightmare.

HP's now-discontinued PhotoSmart 7960 was something of a breakthrough photo printer. Unlike other high-end printers, the 7960's eight inks included shades of gray that made this the black and white champ of inkjet printers. Some reviewers raved that the 7960's B&W output rivaled the silver halide prints made with the traditional photographic process.

Now HP has gone the 7960 one better with the nine-ink PhotoSmart 8750 Professional. This HP photo printer isn't for everyone, though – the suggested price is $499.99.

But for those to whom B&W quality is important… who want the ability to print up to 13” x 19” without borders… or who want prints that last (rated for up to 200 years, when stored properly in an album), it's a good choice.

Should You Buy a Laser Photo Printer?

For many years, the common wisdom was that laser printers were cheaper than inkjets in the long run, because the price-per-page was lower. But that began back in the days of black and white printers. The question is now, “Are laser photo printers less expensive than inkjets?”

And the answer is, “Yes.” In fact, a relatively inexpensive laser photo printer can print a color page for about half the cost of an inkjet print. Part of the equation is that quality laser photo printers themselves have come down in price. A decent color laser printer can cost as little as $300 - $400.

A color laser printer requires four toner cartridges, and prices for these are usually $50 and above. But a toner cartridge lasts much longer than an ink cartridge for an inkjet printer.

Laser photo printers also beat inkjets in the speed department. A full-color letter-size page that might take an inkjet several minutes to produce will be done in mere seconds on a typical laser printer.

But there's one area in which laser photo printers can't compete with inkjets: print quality. A good inkjet will yield a better print than a laser photo printer every time. However, if decent quality is good enough, and cost and speed are important, you may want to consider a laser photo printer.

Transfer Files More Easily

Transferring files from your digital camera to your computer can be annoying. But there's a digital photo accessory that can make it a lot easier.

A memory card reader frees you from having to plug your digital camera into your computer to transfer pictures. There's no messing with cables, because you can leave the card reader plugged into a USB port full-time. Just pop in your memory card and download. There are even PCMCIA versions for laptop users.

Readers that accept multiple types of memory cards start at about $20.00.

Selecting the Right Camera Case for You

For most people, finding the right camera case isn't a problem. There are many good options for compact digital cameras. But if you've just purchased a digital SLR, getting the right camera case is a tougher decision.

There are many styles of camera case to choose from. For example, there are fanny packs, messenger bags and backpacks – as well as traditional shoulder bags. Some manufacturers offer “modular” systems that allow you to customize your bag with pouches, dividers and other accessories. There are even holster-style bags that keep your d-SLR handy right on your hip.

When choosing a camera bag, first consider how you shoot. For example, if you plan to carry your camera and a few lenses when you're hiking, a backpack may be right for you. But you'll probably find a backpack is inconvenient if you do most of your shooting at family gatherings and trips to the amusement park.

The amount of equipment you plan to carry is also an important consideration. If you've just bought your first SLR, keep in mind that you're probably going to add a couple of lenses to your collection. Buying a new bag every time you buy a new lens can get expensive.

Comfort is important. Be sure any belts and straps are sufficiently padded. If it's an over-the-shoulder bag, you may want a little padding for your hip, too.

Spare Batteries Are an Inexpensive Insurance Policy

Imagine if your camera's battery failed just when your child walked up to receive their diploma… or at the changing of the guard at Buckingham Palace. If you do a lot of shooting – especially if you travel – one of the best investments you can make is a spare digital camera battery.

The lithium ion batteries used in many digital cameras typically cost $35.00 - $50.00. But if you're an avid photographer, that's a fairly small price to pay for an insurance policy.

For those who shoot with a camera that uses AA cells, consider a spare set of rechargable NiMH batteries. If you don't use your camera a lot, have a spare set of alkaline batteries handy for your camera case.

A Multimedia Digital Camera with Extras

The NV3 is a new Samsung digital camera that offers several intriguing multimedia – and other - features in a compact package. The NV3 offers movie mode in VGA resolution at 30 fps, MP3 download and playback capability, and – yes – stereo speakers.

The 7.1 MP NV3 has a 2.5” LCD monitor, an internal 3x optical zoom, 11 scene modes, an auto-macro feature for close-up photography and comes with Samsungs Advanced Shake Reduction technology.

Another nice feature is called “Wise Shot.” When you select Wise Shot, the camera takes the same scene once with the ASR on and flash off, and a second time with the ASR of and flash on. You can then select the photo which looks better to you.
