Bokeh And Light Art

Sorry for not posting in a while, so I'm going to make it up to you by telling you two of my photography secrets(:

Bokeh

Bokeh is something I've been trying out lately, and it's all about the focus.  If you have christmas lights, those work best for bokeh.

Bokeh works by having the christmas lights in the picture, but not the focus. literally.  Take something else (The table, for example) and focus on it, and wait for the lights to blur.  It gives it a bubbly, airy effect.  I used christmas lights for this.  Bokeh is the Japanese word for "blur", and you can see why.   The pronunciation is Bo-Kay mainly, but Bo-Key is acceptable too.


Light Art!

Light art is all about the shutter speed.  I like to use a 25-30 second shutter speed, it has the best results if you want a lot of light.  There is an app, I think, for iPhones that can make a slow shutter speed.  If you have a camera, I would look it up if you don't know.  (I would explain how to do it on a camera, but all cameras are a little different)
You have to have a flashlight, or christmas lights.
Turn off the lights, or wait for night to do this.  Make sure it's as dark as you can get it.  Start the camera, the shutter won't close, so it sounds like you're taking half a picture.  Wave the flashlight or draw what you want, and always keep the flashlight facing the camera.  For christmas lights,  Start the camera and shake them around, or if you have them strung from something to something, shake them for a wall of light.  It makes a really cool effect.
The way it works?  
When you take a picture, the shutter opens up to let in light, and closes really fast so the photo isn't flushed because of too much light.  Too much light is called Over-Exposure.  By changing the shutter speed, the camera lets in more light.  This is also the reason why you want it to be dark when you're doing this.  So when you hear the little click, and it stops (like you're taking half a picture)  that's because it's letting in more light.  Have you ever stared at the sun, looked away, and you still saw it?  That's kind of what's going on here.


Any questions?  Leave them in the comments!
