When you push the shutter, all pixels of the camera become active and begin absorbing light while the shutter is open. This allows for high quality and non-grainy pictures. The live preview shown on cameras is only a very low quality preview for a small screen so you know what you are pointing the camera at.
Yes. At the time Annie began photography, there was no other way to develop pictures. Until the advent of such technology, photography used photographic film to create images which could be made visible by photographic processing. By contrast, digital photographs can be displayed, printed, stored, manipulated, transmitted, and archived using digital and computer techniques, without chemical processing.
If you don't gauge your ears they are only slightly visible. If you gauge them then they become much more visible.
A tripod is a three legged stand which a camera sits on so it can be very still and stay in the same place while pictures are taken.Small tripods are also used in chemistry labs to support a variety of lab utensils such as flasks, beakers, Bunsen burners, etc.
Until about ten years ago cameras used film -- clear plastic with a coating that is sensitive to light. The camera exposed light from the scene onto the film which was later removed from the camera and put in chemicals to cause the images to appear. This chemical process is called developing the film. Some professional photographers, serious amateurs, and people who have not yet bought a digital camera still use film cameras. I assume these film cameras are what you are calling 'normal.' Digital cameras create images by light from the scene onto electronic sensors which convert the light falling on them to signals that can be recorded in digital files the way computer data is recorded. These files can then be transferred to computers to be printed.
The Earth and atmosphere absorb the visible and infrared energy and this warms the earth.
Noise. Noise is a visual distortion that looks like tiny colored specs on a photo. It is especially visible in images shot at high ISO or very slow shutter speeds. Noise is the digital photography version of film grain.
As it's already visible it's not lost, is it?
a. computers are used in all digital technologies.
Main Sequence Stars
A majority of visible stars are in the main sequence but it is likely that there are a lot more brown dwarfs than are recorded. This is because they are stars that almost did not quite make it. They are not very luminous at visible wavelengths and so may be under-represented.
No, because mine isn't visible and my voice has already lowered and I don't have fat covering it
The newest digital hearing aids are so small that they can fit completely inside the ear canal. This makes them barely visible to other people.
you don't need a ring of visibility since you are already visible.
Digital watermarking is used to avoid illegal copying of images by integrating a more or less visible copyright notice on the photo. Most image converters (see reference link fro an example) can overimpose digital watermarks on the photos.
Most digital camera sensors are sensitive to a small range of IR, as well as visible light.
gamma img processing,uv imaging,visible imaging,microband wave imaging etc etc
There will be a total lunar eclipse visible in North America on December 21, 2010; it will be very partially visible in the UK as the Moon will go into eclipse as it is setting. There will be a total lunar eclipse on June 15, 2011 primarily visible in India and eastern Africa, which will be partially visible in the UK when the Moon will rise already coming out of eclipse.
