When I was a kid, I used to wonder if everyone saw the world in the same way. What if what I called "yellow" looked like green to someone else? Wouldn't it be interesting if everyone's eyes interpreted color differently? Incredibly, that's not too far off the mark in the world of digital photography, since computer displays are not all perfectly calibrated to the same specifications (see "How to Buy a Monitor" for tips on monitor specs).

Every monitor has its own brightness, contrast, and color levels, and that means a digital photo will look different on every computer you show it on. Imagine working to remove a green cast from your photos only to discover that the green was being generated by your display--after editing, they'll look terrible on any other computer. I talked a little about this phenomenon in "Calibrate Your Monitor." This week, let's take another look at improving your monitor's output.

"How do I get rid of red eye in my photos?" is the second most common question I get from readers.(The most common, of course, is "Are you as handsome in real life as you are in your photo?" and the answer, of course, is yes.) A while back I offered some advice on how to deal with red eye after the fact in "Combat Red Eye," but it's better to avoid getting it to begin with. This week let's look at five simple ways to minimize red eye when you take the photo.

1. Brighten the Room

Let's start at the beginning. Red eye usually happens in low light, when your subject's eyes naturally dilate to let in as much light as possible. When you fire your camera flash, the light passes through the open pupils and bounces off the back the eye, looking red.

What's the hottest new trend in digital photography? For 2009, it might well be face identification. And no, I'm not talking about billboards that track the people watching them. I'm talking about programs that know who's in each of your photos.

Here's the problem face ID is trying to solve: You've got thousands of photos on your computer, and buried among them are a few dozen pictures of Aunt Alice. But how to find them? They're spread across many different folders, with unhelpful names like Thanksgiving04, Vegas_trip, and 100808. That picture of Aunt Alice holding her prize-winning quilt might as well be in a locked filing cabinet in an abandoned warehouse in Newark

Managing Lots and Lots of Photos

I volunteer for a large nonprofit organization. They would like to take their photographs (which I suppose number in the tens of thousands) and organize/archive them. Can you be able to point me in the direction of software designed for this sort of thing?

This season is the stuff that cameras are made for: holiday lights and decorations, brightly wrapped presents, kids anxiously darting around the tree. Your camera is probably getting excited just thinking about the opportunities you're going to give it in the next few days. So as you get ready for the veritable Olympics of personal digital photography, consider these five tips for taking better pictures. Also, if you're shooting outdoors, don't forget my advice on winterizing your camera. And since you'll be taking a lot of pictures indoors, be sure to review my tips for taking better pictures of people and how to get better results in difficult lighting.

Finally, before I get into the nitty-gritty of this week's holiday photo tips, I want to wish each of you a warm, safe, and happy holiday.

Still shopping for the digital photographer in your life--or looking for the perfect item for your own wish list? Me too; my holiday shopping is far from complete. Thankfully, I have some last-minute gift suggestions for you. Last week, I kicked off my annual holiday shopping guide. This week, let's wrap up with a few more shopping ideas.

Stocking Stuffers

When I was a teenager, my parents used to stuff my stocking with film. These days, why not throw a big, fat memory card in someone's stocking? They're ridiculously inexpensive; you can get an 8GB CompactFlash card for $20, for example, or a 16GB Secure Digital Card for $35. You can find a variety of memory cards at PC World Shop & Compare.

I love this time of year. The weather turns brisk, a dusting of snow settles on the trees, and holiday music fills the air. The only downside? Shopper's anxiety: I never know quite what to buy for my friends and family. So that must mean it's time for my annual holiday shopping guide. If you want to see the goodies I recommended last year, check out 2007's "Digital Photo Shopping Guide," part one and part two.

If you have a digital photographer on your shopping list (or if you are hunting for cool things to put on your own wish list), fear not. This week and next, I'll tell you about toys that will make any photographer happy.

We're a month away from 2009. And you know what that means: We're almost eight years overdue for the events chronicled in 2001: A Space Odyssey. Oh, and you're only a month away from needing a new wall calendar. So why not create one from all those digital photos you've been taking all year? After all, there is no shortage of photo sharing sites that let you create a custom photo calendar.

Indeed, most photo printing and sharing sites have some sort of calendar creation feature. My favorites include Costco Photo Center, Kodak Gallery, Lulu, Shutterfly and, Snapfish.

Printing 8-by-10s

I want to print high-quality 8-by-10-inch color pictures. What are the correct camera settings and printer specifications to achieve this output?

There are very few cameras designed from the ground up to work in harsh winter conditions. The Olympus Stylus 1050 SW, for example, is winterized to perform at temperatures as low as 14 degrees Fahrenheit. It's even more rugged than most digital SLRs--my own Nikon D200, for example, is rated to work down to freezing, no colder.

But that doesn’t mean you can't take the camera you already have skiing, snowboarding, or snowman-building this winter. I've found that most digital cameras work just fine even in the dead of winter. With a few precautions, you can snap photos in even the chilliest of conditions. Just don't try taking your camera on an expedition to the South Pole.

When I think about photography, I imagine a National Geographic photographer standing at the edge of a desolate plain, quietly photographing wolves with a lens that's as long as a baseball bat.

But that's just me. I know that the main reason most people buy digital cameras is to take photos of people--and great portraits can be hard to do. So this week, let me share with you five of my top tips for taking pictures of people.

Panoramas--images that combine a series of photos into a sweeping vista larger or wider than what you could capture in a single photograph--are among the most exciting and unexpected benefits of digital photography. Photographers used to need special film cameras to take super-wide panoramas, or they simulated the effect by taping together a set of prints, exposing lots of ugly seams in the process. Now, using software like Windows Live Photo Gallery, Adobe Photoshop Elements, or any number of other panoramic stitching programs, panoramas are easy to make and the results can be, quite literally, seamless.

You probably already know the basic rules for taking good panoramas, like making sure you get about 30 percent overlap in each source photo and using a tripod when possible to keep the horizon level in each shot. For a refresher, check out "Shooting Photos for Panoramas," Part 1 and Part 2.
