HDR and HD timelapse video of Ala Moana fireworks

Fireworks over Ala Moana

My favorite pic of the night. I found three frames from the timelapse below that fit just perfectly together to make an HDR photo. The exposure settings of each of the frames are the same but the rocket explosion cast a wide range of illumination over the three exposures. Wide enough to piece together an HDR in Photomatix.

Photobug details of the time lapse: Shot with my Nikon D90 w/ a Nikkor 14-24 mm f/2.8G. ISO 200, f/4, 2 seconds per frame. Scaled the frames down to 1526×1080 and stitched together with Adobe Premiere elements at around 6 frames per second. The flash player below scales down the video to fit in the browser window. I highly recommend downloading the video and watching it in full screen 1080i.

Hawaii Geek Meet 2009

Last Sunday was the 2nd Annual Hawaii Geek Meet at Ala Moana Park. I met a lot of old online friends and found some new ones. Forgot to wear my Twitter shirt. Ate lots of food – BTW did anyone get a good pic of that hand cart full of pizza? And lastly I took lots of photos as you’ll soon see.

I busted out my hacked Canon A630 and stuck it on a tripod under a tree. Then I ran a time lapse script that took a shot every ten seconds for the whole event. All told, I took around 2000 photos that day. After I stitched the pics into a video, I couldn’t quite find the right geeky music that fits our little group. Then I remembered Twitter Me Gently by Matthew Ebel and everything sort of clicked together after that.

Round Top Sunset Time Lapse

Round Top Sunset Time Lapse


My friend Joe Philipson arranged for a Flickr meetup at Puu Ualakaa Park around sunset yesterday to hang out and practice time lapse photography. I’ve got a Canon A630 which I hacked with the CHDK firmware. I’ve tried stitching together time lapse photos before, but they never quite worked for me. I think I’m starting to ge the hang of it now.

Music for the video is “Restless for the Sun” by Jimmie Bratcher.
