This video shows you how to take psychedelic abstract long exposure photographs of Christmas lights. You'll want to set your camera's shutter speed to to BULB mode and use your camera's pop-up flash (or external flash), then spin yourself around in front of your Christmas tree. It helps if all the lights are turned off in the room except for the Christmas tree lights.
Here are the six different tricks. There will be an image on top, and an description underneath each image.
Spin either in a chair or while standing up. Try not to move your arm, hand, or head while doing this, because it will cause unwanted camera-shake. You can experiment moving your arm up and down or something if you want to, it just will give you a different effect.
Hold your camera by the lens out in front of your with your right hand, twist just like you did in the first trick, only this time take your left hand and move your camera so it zooms in and rotates at the same time. If you do this several times, you should eventually get a result where the lines will twirl around you, like you are in some type of TRON video game or something. And hey, Photoshopping your face using the Liquify tool to make you look like an alien never hurts.
Use a star filter screwed on the front of your camera lens. This will slice and the light into thin lines. This looks cool when you twirl the filter around your lens as well because the stars will appear to be "twinkling".
Use manual focus, still in bulb mode, and simply move your camera around your Christmas tree while the exposure is taking place. You will end up with really techy-yet-beautiful abstract photographs that you can use in backgrounds for Photoshop projects or the like.
Put your camera on a tripod and zoom in while the exposure is taking place.
If you have a higher end DSLR (I'm using a Nikon D300s) there may be a Multiple Exposure function somewhere in the camera's menu. I like to set it to ten and then take several exposures, each shot at a different focal length.
A physiogram is a single long exposure of a flashlight spinning around on a string that is tied to a ceiling. You heard me, simply find a way to attach your flashlight to a string or shoelace or something, then put your camera on the ground with the widest angle you can get (after getting the light in focus, then switching the focus off), turn out the light, turn on the flashlight, give it a good push, then take a long exposure of the physiogram. You can also achieve different kinds of effects by zooming in and out, or focusing in and out while the exposure is taking place. You can also use different colored lights, and blend them later in Photoshop. When you take the photo, I recommend using a 30 second (the maximum shutter time on most DSLR cameras, unfortunately) exposure, or, if you have a BULB mode on your camera, you can use that.
Examples of Physiography:
This last image was manipulated later on a computer.
You could theoretically create a physiogram with a sparkler too. Yep, a firework SPARKLER. How awesome would that be? I haven't done it before, however the idea would be to put your camera on the ground facing upwards underneath some protective glass. Tie the sparkler to a tree branch, weight it down somehow, and take the shot the same way you would take a regular physiogram.
You could also use a tripod pointing down at a mirror, with the light source above the mirror. This way you would capture the reflection, and you would be able to see through your viewfinder. I like using a wide angle lens and just putting my camera on the ground and taking the shot, however.
If your in a highschool photography class, this will totally flip people out. Most, if not everyone, will not know how you did it. At least that's how it was when I did it in highschool.
The Maglight Solitaire Flashlight is a neat little light that enables the head to be taken off, so it can be in "candle mode". This is great for physiograms and also any kind of light painting. You will definitely have an advantage when using it. You can easily change the colors later inside of Photoshop, or some other picture editing program by adjusting the Hue/Saturation and/or by creating a new layer with the blend mode set to Color, and then paint on that layer using a color brush.
Here is a how-to tutorial on long exposure photography with sparklers. I also show you how to make perfectly symmetrical psychedelic patterns just by using your DSLR, Adobe Photoshop, and sparks from your fireworks in part II of the tutorial. Make sure to pick up your fireworks the day AFTER Independence Day because they are usually on sale.
