GoPro Hero Camera

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.
