The question is how many of my readers that will get full of nostalgia when they see these images? I’m a typical “have to keep this, can be useful sometime”-person. I keep way too much rubbish.
But some things are worth keeping for decades. “Lego Space” from the late seventies / early eighties. In pretty good condition, and huge amounts of fun for my son. Born in this century.
Oh, you didn’t keep yours? And want some. eBay to the rescue! Or maybe you want to go all the way and build something with more than 5000 pieces?
Or you want to indulge in info and history? Lego Space in Wikipedia. The complete collection. Lego Space on Flickr.
Standing outside of a fence shooting images of a boat my focus more or less accidentally changed to the fence. And if you ask me, the image of the fence is way better than the one of the boat. Same place. Same time. Different focus.
There are three main factors that influence the quality of a digital image. The resolution is probably the most common. How many megapixels is your camera? Then, we have the compression. If you compress an image to make a smaller file using the JPEG-system you will loose some quality.
The third factor is the so called dynamic range. Can you take care of the details in both the highlights and the shadows? Here’s an example. You have a scene where the sky is dramatic and interesting. But you also want some details on the ground. In the following image I adjusted for the sky. And as you can see the ground is only a silhouette.
So you need to let in more light. Open up the aperture or add some time to the exposure. Very nice scenery, but no dramatic sky. As the next image shows.
Seems like you can’t have it all. Or maybe you can? There are actually a couple of solutions. One of them is called HDR, or High Dynamic Range photography. To put it simple, you combine several exposures into one using some magic mathematics. And the good news is that you don’t need to understand much of the mathematics, there are several tools to make HDR images and you can use most digital cameras when shooting for HDR.
For the image in my example I actually shot three versions. One standard exposure, one with +2 stops and one with -2 stops. All the three exposures are loaded into the HDR software to make an image that will show both the dramatic sky and the forest.
What do you need?
When you’re out in the field you need a digital camera that let you manually adjust the exposure value and a tripod or something to support the camera. The three exposures need to be identical. Or at least nearly identical. Some of the HDR software out there will try to adjust if you have moved the camera slightly between exposures.
When you get back you need a computer and some HDR software. I am using Photomatix Pro. Available for both Mac and Windows. For Mac you can also try the free DRI maker. It doesn’t make true HDR images, but will help you with that difficult dynamic range by combining several images in a different way.
And if this quick introduction was interesting you can go further by having a look at the HDR group on Flickr. Lots of examples, tips and links.
Oyvind adds two good links to tutorials for HDR in Photoshop in the comments. One from luminous-landscape.com and one from backingwinds.
And you can have a look at some of the other HDR images I have made recently. These three are from the beautiful Røisheim Hotel in Bøverdalen in Norway.
After my article about how to entertain your kids with the navigation system in your phone several people have asked how I mount the phone on the dashboard. I use a simple magnetic mount. My wife use one as well, so together with the iPod our dashboard gets slightly crowded with gadgets.
The system consist of a magnet that you mount at the place you want it using a form of double sided tape.
Then you tape a small piece of metal on the back of the phone.
And it will sit nicely on the magnet on your dashboard. I don’t know if this will harm the phone, but I have done it with several models and none of them has been damaged by the magnetic field. The N95 sometimes invokes the mode that would otherwise need you to flip the media playback keyboard open. Exactly when I mount it on the magnet. I guess the switch in the phone that opens that menu when you slide the phone is based on a magnet or something.
