Canon on Wednesday released new firmware for its EOS 5D Mark II camera that the company said "improves and mitigates" the "black dot" problem that marred some images from the high-profile, high-end SLR.

Version 1.0.7 of the 5D Mark II firmware software is downloadable from Canon's Web site. (I encountered some dead ends on the site, but eventually found the 9MB download on the U.S. site at this address.)

I've just run some tests. My preliminary opinion is that there's grounds for optimism that the firmware indeed seems to have taken care of the problem. See the shots below taken at ISO 800 and 3,200, magnified to three times regular size.

This scene of San Francisco by night, taken with a 5D Mark II using the new version 1.0.7 firmware, shows no evidence of the black dot problem.

It's generally not easy right now to label your photos with information about where you took the pictures--the process usually is done with special software to marry the photos with location data taken from a separate GPS receiver.

Phil Schiller, Apple's senior vice president of worldwide product marketing, demonstrated what you can do with iPhoto at the Macworld 2009 keynote Tuesday.

iPhoto 09 works best with photos that already have been tagged. That's getting more common, as GPS hardware support becomes less of a rarity. For example, Nikon's Coolpix P6000 has a built-in GPS receiver, and Nikon has begun selling its GP-1 GPS receiver, which can plug into its SLR's flash mount so location data is embedded in the photo. Apple's iPhone can geotag its own photos, and camera manufacturers say GPS support in cameras has become a matter of when, not if.

But the software also can help you tag your own images. Clicking a photo flips it over, letting you type in a location, then showing the spot using a map. (Google supplies back-end mapping services). Helpfully, iPhoto then can spread that location data to other photos with similar time stamps, and they can be bundled together into a group called an event.

OK, but what can you do?
Once you have geotagged photos, what can you do with them?

For one thing, sift through them geographically using iPhotos' new Places interface. Viewing an iPhoto event can show an associated collection of pushpins on a map, and clicking each pin shows the photo.

For another, you can search for photos based on where you took them, not on whatever filing system you might use. iPhoto can handle geographic hierarchies, so if you labeled a photo with "Eiffel Tower," it'll find it with a search for "France" or "Paris."

Picasa for the Mac includes the ability to make collages and other core features.

Google plans to release on Monday a beta version of Picasa for Mac OS X, helping Apple fans catch up to Windows and Linux users already employing the free tool for editing, cataloging, and uploading photos.

The Mac version largely matches the features in Picasa 3 for Windows, said Jason Cook, Picasa's marketing manager. Though the company has been scrambling to include some secondary features such as geotagging and the ability to get photos printed, the core abilities of Picasa are present, he said.

Picasa lets people edit and print photos, create collages and movies, and add labels, star ratings, and tags. More significantly, given Google's cloud-computing focus, it also lets people upload their images to the company's online Picasa Web Albums site where images can be shared. Google acquired Picasa in 2004.

"We have many Mac users," Cook said, though declining to offer any estimates, "and we think they'll be excited about this. It makes the Picasa Web Albums experience better."

The 55-200mm lens brought me close to this owl in Patagonian Chile, who obligingly didn't spook when I stopped and changed lenses. (Click to enlarge.)

Here's a frustrating combination: traveling and serious photography. At precisely the time you want to photography interesting new surroundings, you also don't want to be burdened with inordinate amounts of gear.

Olympus has one interesting answer to the conundrum, though: the E-3 (click here for CNET's full-on review). Its top-of the line SLR is rugged, waterproof, and when combined with the company's Zuiko Digital ED 12-60mm F2.8-4.0 SWD and 50-200mm F2.8-3.5 SWD lenses provides a flexible package that's portable if not actually lightweight.

I hauled the E-3 with those lenses and the Zuiko Digital ED 7-14mm F4.0 wide-angle zoom to Argentina for a month of vacation and was pleased with the performance. I had to lug the gear not only on the usual buses and city tours, but also in much more demanding conditions: two four-day backpacking trips with a three-year-old, Patagonia's uncertain weather, and serious weight-carrying constraints.

The result was good photos of people, flower close-ups, skittish wildlife, and beautiful mountains.

The gear costs about $1,950 for the camera and 12-60mm lens, $950 for the 50-200mm lens, and $1,400 for the 7-14mm lens.

I'll be honest. What I want is Canon's EF 500mm f/4L IS USM telephoto lens, but it costs $5,600, so let's move on to some options that aren't quite so detached from economic reality for a mostly amateur photographer such as myself.

Obviously my camera is a Canon SLR, but I'm reasonably happy with my setup right now, so here are some items I covet that are more modestly priced and that happen to be neutral as regards camera manufacturer.

RawWorkflow.com's WhiBal white-balance card

1. WhiBal white-balance card. I shoot raw images, which means data is taken directly from the camera's image sensor without any in-camera processing. I like it because it gives me more flexibility for matters such as exposure adjustment. Second in importance to exposure, though, is fixing white balance--for example the orangey color cast you'll often see when shooting under incandescent lights or the bluish tinge of pictures in the shade.

The flip side of raw photography is that it's more manual labor than just grabbing the JPEG, but to me it's worth it. I mostly just eyeball the white balance, but sometimes keying off parts of an image--the whites of someone's eyes or gray and black clothing--gives an easier way to set white balance with software. But for more precision, the WhiBal cards from RawWorkflow.com give an easy way to be more rigorous. You take a photo of the durable card, which shows a standard 18 percent gray, then set the white balance in software off that part of the photo. With modern raw-image editing software, you can synchronize the white balance for a series of images off the one you took with the card. The $19 keychain model looks about my speed. ...
