, because the light is not painted like paint, it is in a 3-dimensional space, positioning is very difficult (how hard it is to know), especially to carry out some complex graffiti, it is best to separate local to draw, a picture, finally PS in a picture.
If there is a certain amount of light painting experience, want to carry out exploratory experiments, 3-4 of people's small combination is good, 3-4 of people come out of the idea of easy to produce some unexpected harvest.

The best way to stabilize your camera is not to fully hold it. If possible, place it on a tripod, on a table, on a rock, on a fence bar, on the roof of a car, or on other solid and stable objects. It means a tripod with a stand, clip, ball head or other lightweight and convenient alternative. But when you only have your camera, camera strap, and the shutter speed you can take at the aperture of the lens is
five. The multi-layer coating lens looks dark, and the color is green or dark purple red.
In recent years, there have been some dual-tube telescopes coated with red reflective films. Dishonest shops also say this is an infrared model, especially suitable for evening use. In fact, the layer of red coating reflects a large amount of light out of the telescope, greatly reducing the amount of light reaching the eyes. Therefore, do not purchase this type of telescope.

Panoramic picture? But just take a few photos and then piece it together in Photoshop. You can use the automatic Photoshop Merge tool, or use the Stamp tool manually. Because any so-called "automatic" thing is not 100% accurate, so we will combine the two.
Obviously, the first step is to take a picture, but the panoramic picture is not very good to shoot. I used a set of photos taken by my friend Alvaro Gumucio aka Gumo, who used Nikon D700 specifically for psdtuts

In actual use, we found that digital cameras have higher requirements for light and are especially important for indoor shooting. Therefore, we should try our best to use the flashlight when shooting outside the room.

other is to hook the camera belt around the neck and pull the camera forward to the belt, the three points of support have been formed, and the stability of the camera has been greatly improved. I have used this method to take a lot of clear photos when the exposure speed reaches 1/8 seconds. You may also try it; the third method is to add a shutter trigger to the tripod. However, some cameras do not have a shutter interface, and the shutter line is

There are many methods to achieve a safe shutter. The common method is to open a large aperture. However, when a small apertu
The world is changing too fast! In human history, we visually express our abilities, functions, speed, and control. You can pick up a digital camera, take a photo for your child, and input the image into your computer within a few seconds. You can use the image editing software to process the image freely, then you can print out the image or send it to a friend in the distance over the Internet. All of this can be done without leaving home. When we record images in the digital magic box, we also

And this can give people the visual effects of stars coming out of the center of the photo. ”
