02.03.12How to get rid of vibrations in your multi rotor helicopterIf you want to snap images or record video from your quadcopter it needs to be as vibration free as possible. When you manage that you get shots like these: But when you start googling you get the same answer all over: 1. Balance your propellers 2. Balance your motors But I did that: And I still had vibrations, blurry stills and jelly-looking video. After a lot of trial and error found the solution. It doesn't matter how much you balance your props if they're the wrong props. You need high quality very stiff props for aerial photography (AP). So, on the same quad, with perfectly ...

06.14.09Test images from my current camerasAs part of some experiments I'm running I snapped more or less the same image with all the cameras available to me today. The devices you see in the image above in addition to my 5D Mark II (that I used to snap that image...). Simply because I wanted to be able to compare some details. And my conclusion? Once you go full frame you never go back. If I'm shooting anything even remotely serious I'll bring my 5D2. Now if someone could give me a full frame digital compact with the size and weight of my old analog (and indeed ...

05.26.09HDR TimelapsevideoI've written about the HDR effect before. And I've written about timelapse several times... Per Erik Sviland just published a video that combines the stuff.

Gruda/Ullandhaug HDR Timelapse in HD from Per Erik Sviland on Vimeo. Per Erik has also been kind enough to include a nice how-to explaining how he made this video on his blog.

11.06.08How to make that cardboard ‘hood’ for the DIY bokeh effectEarlier this year I posted an article about how to make your own "bokeh" in your images. People have asked me for details about the cardboard "hood" I've been using. So I decided to simply tear it apart and put it together in front of my video camera. Three minutes and fifty seconds later. And there you are. A nice tutorial on how this was put together. DIY bokeh from Eirik Solheim on Vimeo. Direct link to the video file.

08.06.08Automatic geotagging of your imagesYou're geotagged, baby! Six years ago I did an experiment after returning from a trip in France. I matched the time stamps of my digital images with the time stamps in the track from my GPS to be able to automatically place all my images on a map. At that point the trick included a lot of manual work, coding and hacking. Fast forward to 2008 and there are a lot of software to help you do this. And I really like all solutions that can help me with automatic tagging of my images. Like most people I'm not too clever at ...
