Optics

Optics, as a field, is often considered largely separate from the physics community. It has its own identity, societies, and conferences. The pure science aspects of the field are often called optical science or optical physics.

DxO Optics Pro Review The most well known feature of the award winning DxO Optics Pro from DxO Labs is its ability to correct perspective distortion, but this isn't what sold me on switching to it as my preferred raw converter.

Lenses & optics - fhe basics Apart from the CCD in a digicam, the lens is the most important element to ensure a quality image. Most digicams have zoom lenses which allow you to vary their focal length from wide-angle to telephoto.

OPTICS - The branch of physical science that deals with the properties and phenomena of both visible and invisible light and with vision.

Optics. The science of light. This includes its properties, the ways in which it is created, the way in which it travels through space and various media, its modification by prisms, lenses, etc.

Optics is the science dealing with the behavior of light. Ordinary emulsion is a term applied to a photographic emulsion which is only sensitive to ultra-violet and blue light.

Good optics (sharp, most shutter speeds are HIGH, better low-light performance) Little need for post-processing (good levels, good colours, sharp) Great menu system Good controls layout, intuitive No barrel distortion ...

Clean Optics It is quite easy to touch the optics of a camera and leave fingerprints. The result is that your pictures do not turn out clear in certain areas.

Fiber optics An optical system that uses glass or transparent plastic fibers as light transmitting media. These cables have greater bandwidth than electrical transmission through wires. Fiber-base Photographic papers without a plastic coating.

fiber optics: An optical system that uses glass or transparent plastic fibers as light-transmitting media; a fiber-optic cable consists of a bundle of glass threads, each of which is capable of transmitting messages modulated onto light waves.

Fiber Optics A flexible bundle of light-transmitting fibers used for medical, scientific, and difficult-access situations.

Pinhole optics, by the way, are not only used in photography. There is one animal in nature which uses a pinhole for seeing - the mollusk Nautilus. Each eye has an accommodating aperture - the aperture can enlarge or shrink.

Review of DxO Optics Pro I also like black and white at night where our vision is much more aware of light sources and deep shadow. Black and white can give a distinct atmosphere of its own such as the shot of a local Jazz bar from outside.

Collimation This refers to how correctly the optics are pointing towards each other. If a telescope is out of collimation, you will not get as clear an image as you should. Refractors generally have fixed optics, so you don't have to collimate them.

Enlarging usually produces positive images that are larger than the negative image; however, because optics are used in projection printing, the image formed on the paper can also be made smaller or the same size as the negative image.

These optics are great for those who want to travel light but still be able to cover everything from wide-angle to telephoto shots. A few years ago, I would not have recommended this type of zooms as they were not optically as sharp as other lenses.

An image sensor of about 1 square inch requires super excellent optics if the resulting images are going to be made into big prints.

For film cameras, now that lenses have been designed that minimize the distortion of different colors of light bending differently, there isn't much of a problem if we use high-quality optics, ...

3D viewing glasses (I used the cyan and red glasses from American Paper Optics). You can also make your own with the filter material below. Black mat board from an art store.

Founded as a workshop for precision mechanics and optics in the German city of Jena in 1846, Carl Zeiss is today a global leader in the optical and opto-electronic industries.

The camera obscura had a lens/mirror optics as light opening, the "media" in the camera was the painter who traced with his pencil the contours of the image projected onto his white paper sheet.

Part of the problem is that your camera's optics introduce distortion when rendering broad panoramas on tiny, two-inch screens.

The scanning takes place inside the television tube as electrons, guided by electron optics, sweep linearly across a tube face coated on the inside with a phosphorescent material.

Rip the optics out of a standard film camera and hold it in front of your digital camera, you get extreme close-ups and the optics are not too bad. However, there is very little DOF since most compact digital cameras don't offer very small apertures.

Macro - Macro lenses are lenses where the optics allow for high magnification of subjects. "True" macro lenses record the image at the same size as it appears in real life. This is a 1:1 macro. Not all macro lenses are actually "true" macros.

The optics are excellent. No vignetting, and zoom works fine. Auto-Focus works fine, and the depth of focus is extremely deep. With manual focus you can focus to just before infinity, and everything will be in focus.

Perspective Control Lens: A wide angle lens design featuring optics that can be shifted to correct for converging vertical lines, inherent in wide angle lenses.

Projector A projector is a device that integrates a light source, optics system, electronics and displays, thus projecting an image from a computer or video onto a surface for large image viewing. QXGA A resolution of 2048 x 1536 pixels.

Understanding your subject matter - the scene, your raw materials - elements and attributes, your tools - the camera, lenses, filters, film, basic rules of optics and exposure, etc. is only a first step.

I would love to read about composition, the technical nitty-gritty of optics âE' why does the DOF get smaller when using larger apertures, exactly what do 70-200mm mean, etc. âE' color theory, etc.

Used to describe the view seen through a pair of binoculars when the internal prisms or optics have been knocked out of alignment or the body is sprained. When this has happened, you see two separate images that cannot be brought together.

The entire system can fit into a small waist bag Quietness Superb for available light shooting Superb optics Unfortunately, RF design has disadvantages as well. We will cover it in following section. SLR vs. Rangefinder SLR Rangefinder Pros ...

Then, consider the trade-off between the optics quality, the camera's weight, the convenience of a prime vs. a zoom lens, lens speed, focal distance and price. Often it will be a balance of these considerations that leads you to a good camera.

Sounds like science fiction but liquid lenses that focus by changing shape are now being used in some camera phones. Courtesy of Varioptics. Click to explore how the size of an image sensor determines the focal length of a lens.

So if you want to scan at 4,000 dpi with possibly the best optics and scan quality you can find, you will part with nearly $1,100, and if you want to use a 50 slide batch processor, add another $500 to the bill.

Note the highly uneven sky brightness at the seams, which was primarily caused by pronounced vignetting (light fall-off at the edges of the frame caused by optics). Move your mouse over this image to see how well the multi-resolution spline performs.

Purple fringing that occurs because the image sensor doesn't capture the different colors (wave lengths) on the same focal plane through the lens. Can be caused by the lens optics. CMOS Image Sensor: ...
