I recently bought a 5MP GoPro Hero Helmet Camera – Amazon had the best price at around $190. Loaded with a cheap 2Gb SD card, I was hoping to get some fun shots when I’m snowboarding, mountain biking or driving one of the Land Rovers somewhere interesting (unless anyone wants shots of I-25 every morning).

I took it our for a test run today, I was snowboarding in Breckenridge. In summary, it’s an acceptable camera as long as you’re just after snapshots, or need a camera to go somewhere hazardous where you wouldn’t take your D-SLR, for example. I had to explain what it was and how it worked to about ten people today. GoPro should hang-out at the resorts, I think they’d sell a boatload. 

Pros:

• It’s cheap
• It’s small and lightweight
• It seems robust
• It takes a lot of images
• Once started, you can forget about it
• The images are acceptable for web use

Cons:

• The images are only acceptable for web use
• The sharpness of the lens isn’t great
• There’s no way to compensate for exposure (or, at least, I’ve not found a way)
• In video mode, the camera is hunting for the correct exposure continuously, which is very distracting to watch
• I find the interface a little non-intuitive, and it’s a pain to remember if it’s on or off

Here’s an example video I shot. Checkout the exposure which is all over the place. To be fair, most cameras have a problem exposing correctly for snow, but I though the hunting was a bit too much.

I also uploaded some test images to flickr. Here are some of them (click on the image through to flickr). 

This image shows the detail around the clouds but also shows the underexposure because of the bright snow.

Here’s the same image, tweaked in Aperture to correct the exposure.

This next image shows the color definition (unretouched). It’s also a good example of how the lens falls off in sharpness at the edges, best viewed on the original image. 

Another example of the falloff in image clarity at the edges (best seen on the original image).

Finally, here’s another unretouched image showing how wide the 170 degreee lens is – the bar is the edge of the chairlift. 

After I saw Michael Arringtons post on “Animoto On the iPhone“, I had a little play with both the iPhone app and their website. I’m impressed. It solves a problem I’ve had for a while – how do I make quick and dirty slideshows from my photos? Well, with it’s flickr/Facebook/SmigMig/Picasa/photobucket integration, as well as the ability to upload photos and music from your computer, it took me <1minute to get my first 30s video working. Take a look here: 

I’m liking it, in fact I’ve just bought an “all-access-pass” which will let me create and download longer videos. 

So far, recommended.

I’ve been a fan of James Nachtweys images for a long time. I’m a fan of the documentary style and love photos that tell a story, even if, actually, especially, if that story is of hardship, unfairness or suffering. The truth images like this show spreads awareness, and with awareness there can be action. As Nachtwey puts it:

“I have been a witness, and these pictures are my testimony. The events I have recorded should not be forgotten and must not be repeated.”

Nachtwey spoke at TED 2007. He was one of the three prize winners and was awarded $100,000 and a wish to change the world (E. O. Wilson, another of my heroes, was also awarded a prize). His (21 minute) talk is below, and contains graphic images.

His wish:

“I’m working on a story that the world needs to know about. I wish for you to help me break it in a way that provides spectacular proof of the power of news photography in the digital age.”

Well, it took a while, but his wish was revealed in early October 2008 (also very graphic):

He has also established xdrtb.org, with the goal of creating awareness around extremely (or extensively) drug-resistant tuberculosis or XDRTB.

Incredible, moving images of a terrible disease.
