System Updated Notice

2007 • Posted by Kai @ 4:04 PM

It is another rainy day, the only thing I can do is stay inside the house and work on my computer. By this chance, I upgraded the blog system to WordPress 2.2. The manual says there are hundreds bugs fixed and some improvements, but I think the stabilization is the most important thing. Didn’t encounter any troubles so far.

And I also added some new features in to the blog. On the bottom of the sidebar (right hand side) there is an RSS button allowing people subscribe articles of this blog. And on the bottom left of each article there is a “Share This” function that you can bookmark or email your friends the article by hitting this handy tool.

By the way, I try to keep this website stylish and elegant, but there are still the compatible issues in between the browsers, especially Internet Explorer. For example, I just fixed some css code to suit both Safari and FireFox. If you find something look awkward on this website please let me know.

Photographing The Northern Lights

2007 • Posted by Kai @ 6:21 PM

Some people ask me how to take the northern lights pictures, I certainly had quite of few experiences. So here is the list that you need for shooting aurora:
• Camera – of course
• Wide Angle Lens – yes, as wide as you can get
• Tripod – because you need to use the Bulb Shutter, so the tripod is necessary
• Shutter Release Cable – to keep the camera and tripod steady when you press the shutter
• A Mug Of Coffee – or some hot drinks. I am not joking because mostly the northern lights appear in cold seasons, you need something to keep yourself warm

That is basically it. And when everything is prepared, here are the exposure suggestions:
• ISO/ 100, Shutter Spped/ 1 minute, Aperture f/ 2.8
• ISO/ 200, Shutter Spped/ 1 minute, Aperture f/ 4
• ISO/ 400, Shutter Spped/ 4 to 6 seconds, Aperture f/ 1.4
• ISO/ 400, Shutter Spped/ 40 seconds, Aperture f/ 4
• ISO/ 800, Shutter Spped/ 20 seconds, Aperture f/ 4
• ISO/ 1600, Shutter Spped/ 10 seconds, Aperture f/ 4

The above suggestions are meant only for reference to get you close to the well-suited exposure. Remember there is no precise photographic exposure setting because the northern lights vary considerably in brightness and stability. I’ve experienced a very glary aurora in the Kings Park about two years ago (check the GALLERY section). Normally, I will suggest do not expose longer than 1 minute because the northern lights stay no still, they move and sometimes move very fast. So if you exposed too long you will only get the pictures with the green sky.

Now you know how to shoot the aurora borealis, but where and when you can see the northern lights? Well, first of all, make sure you are living in the high or middle latitudes. And then here are couple websites that you should follow; the aurora forecast site Space Weather predicts when the northern lights appear, but the accuracy is just like your local weather forecast (oh, I didn’t say anything). The K-index shows how strong is the geomagnetic storm in every three hours, and then check the Aurora Sentry see if your areas are covering in the visible auroral oval.

That’s it! So next time when you see the northern lights, try to take some pictures.

Photo Assignment: Bottle or Jar

2007 • Posted by Kai @ 3:30 AM

Not used to drink because I don’t really like the taste of beer. This was just a weekly assignment from a photo forum that I done a quick shot with my little Canon DC. As you can see the main light source is from bottom. I shouldn’t be lazy by using this tiny digital camera because it turned out a such bad quality.

Alston’s Family Portrait

2007 • Posted by Kai @ 4:06 AM

Just uploaded Alston family’s pictures in the GALLERY section. I was trying to do some photo effects onto the pictures, but after I processed couple photos I realized originals are the best, so I didn’t do any post processing to the pictures. Pretty lovely family and Izzy is so cute.

Joyce & Chris Just Married

2007 • Posted by Kai @ 5:09 PM

First of all, congratulations to Joyce and Chris just married. I went out at 7:40am in the morning, and got back to home at 1:00am midnight. More than 16 working hours and went through all the process with bride, groom, bridesmaids, and groomsmen. Holding the heavy camera gears all day, I can’t barely raise my arms at the evening, but I still have to keep holding on it to get the job done perfectly. It was a pleasure to work with this new couple, and there are tones of pictures that we produced waiting for me to process. I just took a quick look some of those pictures and found there are many decent shots, quite satisfied.

Doing wedding photo is an interesting job with a lot of pressure. You can’t screw it up because it cannot be redo or undo, and so I brought another camera body and couple rolls of film as the backup system, in case of digital system won’t work.

When You’re Gone

2007 • Posted by Kai @ 7:40 PM

This is the first time I worked on GarageBand with only laptop (no musical keyboard). It’s hard to input all notes with computer, but it makes thing possible if I wanna do this during my trip. The song “When You’re Gone” original by Avril Lavigne, and here is Kai’s version [When You’re Gone]. Any comments are welcome, oh , of course I lowered the pitch a bit to match guy’s tone.

IR Wedding Photo

2007 • Posted by Kai @ 8:18 PM

The camera sensor captures visible light as well as infrared light, so for taking the infrared pictures we need to attach a infrared filter on the front of the lens to block all visible light and only let infrared light pass through the lens. Most IR (infrared) technique was utilizing in landscape photos, rarely been used for portraits or weddings. It would be interesting that using IR to create this kind of sci-fi wedding scene.
