Most of your who visit Fear of Lightning are probably well familiar with laser weaponry, thanks to Christopher's three-part series covering carbon dioxide, flashlamp, and semiconductor lasers. Another type of laser currently being developed as a weapon is the fiber laser, which is compact and efficient, but much weaker than a chemical laser. Fiber lasers are more commonly used in laser cutting and marking, telecommunications, spectroscopy, and of course... music.
I was just very amused by this commercial for Portal.
This video gives viewers an overview on how to use the manual settings of your DSLR camera. Aside from the Auto setting, your DSLR camera has the P-mode which is the program mode, S-mode which is the shutter priority mode, A-mode which is the aperture priority mode and finally the M-mode which is the complete manual mode. P-mode or program mode is more like the Auto-mode in your camera. You can't control your shutter speed and f-stops (aperture) however; you can manipulate the other settings ...

One task to which DSLRs are particularly well suited is nighttime shooting. Fast, wide-aperture lenses make the most out of available light. In this video tutorial from renowned DSLR cinematographer Philip Bloom and the staff of Vimeo, we receive some tips on how to film at night using, for example, a Canon 7D, T2i (550D) or 5D Mark II.
If you want to engage in macro photography and can't afford a close-up lens, you may be in luck. By using a "G" lens (that is, a lens that does not have a built-in aperture ring) it is possible to reverse the lens and take close-up shots with your camera, without having to buy any additional equipment.

Light painting or light writing is one of the coolest of the coolest multimedia arts. It consists of setting a camera for a very long exposure in a dark area, then moving light sources around in front of the camera. When the aperture finally closes, you will have a photo where the light is preserved everywhere it was. Basically, you've drawn on a photo with light. How cool is that? This video will show you how to do it quickly and easily, allowing you and your friends to enjoy this exciting n...

This video shows you how to light a bottle with long exposure in photography. The end result is to have a picture of a bottle with glowing edges with a black background. For starters you set your SLR camera settings to a 30 second manual shutter speed and a f5. 6 set aperture. Put the camera on a tripod for steadiness and set up your subject. For the subject, on a table, place your bottle in front of your chosen drop cloth. It is best to choose a color similar to the bottle. Then you use a li...
In this Fine Art video tutorial you will learn how to understand your lens and its effect on depth of field. The lens in the video has some inscriptions which are interpreted like this. 50mm is the focal length of the lens. The aperture is from f1.4, which is the widest lens opening to f16, which is the smallest lens opening. The higher the number the lesser the lens opening. Aperture determines the amount light that comes through the lens. Aperture also decides the depth of field. With a wid...

In this video from clickherephotography we learn how to take great photos by using depth of field. In a picture of a bird he used an aperture of about 5.6 which increased the shutter speed on a 300mm Canon lens. With depth of field you can blow your background out. If you used a higher aperture, a lot more of the bird would have been in focus and a bit of the background would have been in focus. By using an F-stop and this aperture, you really bring the bird or whatever object is in the foreg...

When taking your photograph using DOF, it is imperative to remember that the shutter speed and aperture (or F-stop) need to change at e...
In this video, we learn how to use and understand depth of field in photography. If you look at a photo, the depth is how deep the picture looks. You can change the depth by changing the aperture to make the depth of field look shorter or longer. The lighting can also change the depth of field and what you can see in the background. A big aperture will give you a large depth of field, with a small amount of light. If you want a big depth of field in a landscape, then you will use a maximum ap...

Mark also goes over the important roles that aperture settings and film speeds play when attempting to successfully balance flash and ambient l...
Have a passion for photography but know nothing about the basics? This video might be a great place to start on the topic of shutter speed. Shutter speed is the amount of time that the film, or your digital sensor, is exposed to the light. Whether it be outdoors, at night, or low indoor light, the shutter speed allows your camera to take a photograph with the correct amount of exposure in reference to how much light is readily available in your setting.
Want a way to reduce or increase the exposure of your camera's sensor without actually having to adjust ambient light levels? Apart from changing the aperture of your lens, you can adjust your camera's ISO setting, which will increase or decrease your sensor's sensitivity to light. To learn more about ISO, and to get started using custom ISO settings on your own DSLR, watch this free photographer's guide.
In this Fine Art video tutorial you will learn how to focus stack for great macro photos. This video is from EPhotoZine. The idea is to take several pictures of the same subject at different distances. For this you will need focus stacking. If you focus with a wide aperture, everything in front and behind the subject will be out of focus. The idea of focus stacking is to shoot several shots and put them together in a program that automatically brings them all into one. And that is focus stack...
