Working with Slow Shutter Speeds

Image
Many digital cameras (from digital SLRs to simple point-and-shoot cameras) now include an option to adjust the shutter speed , or how long the shutter of the camera is open. This allows you to capture not just a moment in time, but maybe a few seconds, or more, in your pictures. The above picture is of the Champs-Élysées, a very busy street, in Paris, taken from the Arc de Triomphe. For this shot, I left the shutter of the camera open for 30 seconds. During that time, cars drove down the street, and because the camera captures any light while the shutter is open, it results in streaks of white and red lines from the cars' lights. To use this feature, you'll want to look for any kind of shutter-control mode on your camera. Canon (and probably a few others) call it "Tv" mode, for "time value." Once you've found it, try increasing the amount of time that the shutter is open (a typical amount of time for a regular picture is usually between 1/200th and

The Rule of Thirds

Image
Almost everyone who has picked up a camera has heard of the rule of thirds , but not everyone uses it when composing their photographs. And while some photographers write it off as a trite technique, there's no denying that it can improve your pictures. The idea is to envision a 3x3 grid when looking through the viewfinder of your camera. Imagine where the grid's lines would cross, and place your subjects at those intersections (like in the grid that follows). In addition, it is a good idea to place any lines (horizons, edges of buildings, etc) along the lines of the imaginary grid. In doing so, you draw attention to certain points in the picture, while at the same time introducing an interesting, non-symmetrical composition. I used the rule of thirds to compose this photograph of a statue in Rome, with some ruins in the background. I've put a grid on the picture to show how I used the rule of thirds to create a more interesting picture. Notice how the top right inters

Hard Light

So I'll start this blog off with a quick post about using the blend mode known as hard light . If you've used the layer feature in Adobe Photoshop , you probably know that there are a multitude of blend modes , from normal to overlay to soft light , among many others. These blend modes can be used for a variety of effects, including special effects as well as simple photo touch-up. I like to use the hard light blend mode to brighten up my pictures (usually landscape or nature photographs). Adobe describes hard light as follows: Multiplies or screens the colors, depending on the blend color. The effect is similar to shining a harsh spotlight on the image. If the blend color (light source) is lighter than 50% gray, the image is lightened, as if it were screened. This is useful for adding highlights to an image. If the blend color is darker than 50% gray, the image is darkened, as if it were multiplied. This is useful for adding shadows to an image. Painting with pure black o

Introduction

Well, I decided to start up with another blog again. My idea for this blog is to post pictures I've taken/edited (only a few at a time) and write about maybe what's in the picture, any special techniques I used to take it, any editing techniques I used, etc. Maybe I'll post some before and after shots. I hope to make this into a blog that can help other people produce better-looking photographs. I think what I'll do is post a picture, then explain something about it. This is inspired by a few friends who praised some of my recent pictures :).
