Interestingness

ByMatt

Since I started using Flickr to show of my photography to the world, I’ve neglected my own self-hosted galleries here at Mineral2.com. I’m considering doing away with the Gallery software altogether and maybe swapping it out for a simpler interface for displaying a portfolio.

At any rate, Flickr has been a much better interface for me because in addition to being a photo hosting site, it’s also a social network and that allows me to get greater exposure into the world. One of the things Flickr does is rate your photos according to “interestingness.” I’m not exactly sure what that entails, but its some magic formula combining the number of views, comments, and favorites an image receives, and I’m sure the rate at which these are received is taken into account. Every day, Flickr takes the top 500 uploads and displays them in a section they call Explore. Given that there are millions of photos uploaded each day, making it into Explore is quite challenging, but also quite an honor. Or maybe it doesn’t really mean anything at all. What confuses me is that most of the images that make Explore probably don’t deserve to be there. After all, the algorithms used to generate the interestingness score are more so a reflection of popularity than the technical quality of a photograph. In addition, a photo with fewer views, comments, and favorites can be ranked higher than one that exceeds it in all three categories. So while it’s fun to get a photo into Explore, it’s not necessarily a reflection of your ability.

Flickr also uses this algorithm to return back to you your top 200 interesting photos from your photo stream. I mostly keep track of the top 20 from time to time to see if the list matches my top picks. For the past few years, my top three images have been some old favorites: the waterfall at Heatherbrook, Mount Washington from Mount Chocorua, and Blue Mine (Wyanokie) Falls.

In fact, it seemed that a good handful of the top 20 were waterfall shots. Most of the top 20 dated back to my film days, and only one made the list from my first year in Idaho. In short, the top 20 seemed pretty robust. But recently there was an upset that changed my top 20. Two images from the past week jumped right up into the list, one of which landed in the number 3 seat. Both of these images coincidentally also made it to Explore for their respective upload dates.

It’s kind of neat to see that this list really isn’t as robust as I thought it was, that an image had to stand the test of time and gradually rise to the top. I’ll never understand just how Flickr’s algorithm chooses the best images, but I’ll be keeping an eye on the interestingness to see how it changes.

    Storms

    Last night, we had the storm of storms come across the Palouse. It was a quick, but powerful cell the big lightning strikes every few seconds that produced enough power to disrupt phone service (land line) each time a bolt struck the ground. Luckily, we had no major power surges and all of the electronics in the house work just fine. But the ligntning and thunder show was both awesome and a bit frightening. I stood outside with the camera as the storm approached, but quickly retreated into the house as the storm came atop of me. Winds picked up…

    Chickadees

    For Christmas, I bought Erin a new bird feeder to replace one that had been broken earlier in the summer. A few weeks ago, we finally got some seed and put it outside, but this was in the middle of a cold snap where daytime highs remained in the low 20’s, and the nighttime lows, well, we just won’t go there. For about a week, the feeder hung with no activity. Then, as the cold began to lift, there was a single chickadee in the lilac tree. It must have spread the news because a few days later, the feeder…

    Aurora

    We got alerts that a solar flare could cause an aurora that would be visible into the middle states. So, last night, I checked the sky and luckily it was clear to the north. I saw a faint glow on the horizon and set up the camera. Sure enough, there was an aurora. The excitement didn’t last too long. I wanted to view this one from Steptoe Butte, one of the best places around for viewing auroral activity. So, we got in the car and started driving west. Unfortunately, the sky was overcast over much of the Palouse, and by…

    Aurora, part II

    Well, I made my last post a bit too soon. After spending the evening on Freezeout Ridge (story and photos to come soon), Erin reminded us that the aurora might still be occuring and that we could possibly see it tonight. Clarkia isn’t the best place to test this hypothesis because its surrounded by tall mountains in all directions, so as we passed through Bovill, I noticed a glow on the northern horizon. At this point, it was only 10:00, still early enough that the glow could be residual light from the sun. I pulled the car over and set…

  • Palouse Photography: Waiting for the right light

    This post will demonstrate just how fast light can change, especially during sunrise and sunset. These three images, taken in the same location on the same day within a half-hour window, demonstrate just how quickly light can change. Therefore, it is often necessary to scout out locations before setting up your desired image so that you can be ready to capture the scene when the light is perfect. Of course, perfect light is a subjective quality. All three of these images are wonderful, which means all three lighting scenarios are desirable. I spent as much time as I could at…

    The Birds at our Feeder

    We get lots of birds in our trees in the front yard. This could be contributed to the source of food we are supplying to them. The list of winter birds is less than the summer residents. For example, I haven’t seen a bluebird in months, and most of the woodpeckers have left the yard too. And of course, the hummingbirds have gone since they don’t have the proper gear to tolerate the cold. But even with the few remaining species, watching the feeders has been a delight. In Idaho, we have the possibility to see four different kinds of…
