PHOTO SHEET MILLION HAVE MEANING

Photo is a recording of a situation by capturing the light by a device called a camera and made ​​by a photographer. In other words, the photographer can be called also as a painter with a medium of light and camera. A painter must be able to express a situation so that the work of photo able to communicate with people who saw the photo.

Photo is one of art to communicate, for example by looking at a photograph we digest what is going to be submitted by a photographer. Therefore, the art of photography is often used as a medium of documentation to capture moments of human life. Lots of photos of a very precious in our lives, which moment is often not possible to be started again in the future. Therefore, the photo is price-less.

Understanding the art of photography is the art or process of taking pictures and light on the film
photography word itself comes from Greek language support, photos (light) and graphos which means writing.

Art photography itself is a bitmap image which aims to convey a specific purpose or just for beauty. art photography taken from 2, namely through the process and through a moment

Activities create with light is of course very much related to the perpetrator (subject)
and the object that is recorded for each shoot has a different view about the weather conditions, natural scenery, plants, animal life and human activity as seen behind the camera lens. How to view or perception is then reflected through the camera shots. The result is a work that photo is the result of the creator's ideas or konsepdari photo

Adreas Feininger (1955) once declared that "the camera is just a tool to produce" works of art ". The more of artwork that can depend on the person operating the camera.

When a photograph is the result of creative work from the photographer, of course no response from orng have viewed it. The late Kartono Ryadi, seasoned photographers in this country once commented, that a good photograph is a photograph that has the power of another shock. View about how the value of good photographs were also raised by a professional photographer, Ferry Ardianto.

According to her informative picture that includes the context, content, and composition (layout and lighting). That he is, the context means that there are things to be visualized clearly, for example about the scenery. On the term meant what content you want to appear to meet the context of the picture.

Photography is an art because not only perpetuate the reality of the image that comes from the surface in a dark room, but more than that, photography gives a picture of poetic language which, according to Roland Barthes, in semiology was never "innocent" because the images are arranging a sistempertanda that can be captured. image
terebut always have the opposite goal. While looking at relitas in photos by Barthes in Seno Gumira is the process of photographing themselves, as Roland Barthes, is the fact that the subjects viewed the destruction process, before finally presented sembali analogy in two-dimensional photo paper, A view of the subject that diprotet staring through the eyes of a photographer, and not another.

Canon typical dial mode

Canon EOS Digital has a mode dial that is not much different from most other DSLR cameras. There is an Auto mode, five creative modes and several presets for specific conditions (basic zone or scene mode). Overview explanation of the creative modes, namely:
* P (Program): like the Auto mode but we can go from some combination of aperture and shutter are possible
* Tv (Shutter Priority): the camera determines the best settings, while we determine what shutter speed to be used
* Av (Aperture Priority): the opposite of Tv, we determine the diaphragm aperture while the camera set the shutter speed corresponding
* M (Manual): shutter and aperture control will be purely on us as consumers
* A-DEP (Depth of Field / DoF Preview): the camera will use the smallest aperture (stop down) for DoF preview (as it reduces light entering the display in the viewfinder would be a bit dark).

EOS camera auto focus system

In principle, auto focus (AF) on EOS cameras use the AF motor in the lens, in other words all Canon EF lenses have AF motor in it. This is different to that has motorcycle Nikon AF on the camera body (although not all have a Nikon digital SLR AF motor), in other words not all Nikon lenses have AF motor. However, Canon did not treat each with the same lens, which lens provided cheap and expensive lens AF motors of different types and quality.

There are two types of motors in Canon lenses, namely:

* Motor AFD (arc-form drive) or micromotor drives -> for cheap lenses
* Motor USM (ultrasonic motor) -> for expensive lenses

AFD motor is a conventional micro motor and cheap. It poses a rotating magnetic coil when energized electrical voltage. Motor is quiet noisy when spinning and the speed was mediocre. Note that the lens Canon EF / EF-S is not labeled USM motor in it means taking the AFD system (confused with Nikon AF-S lenses that must have been wearing motorcycle SWM).

USM is a new tekolonogi motor that drives the motor with a wave that provides higher speed but with a more refined sound. But again, dividing the Canon USM lenses with this technology into two groups, namely USM lens for expensive and USM lens for an ordinary lens.

The two types of motor USM in Canon lenses, namely:

* Based USM lens ring for expensive (see example image above)
* Based USM micromotor for a cheaper lens

Differences exist both in the working principles and the ability of instant manual focus (FTM: full-time manual). In ring-based USM lens, we can simply turn the manual focus ring anytime we want. So switching from auto focus to manual focus can be done directly without moving the lever AF to MF. When using a non USM lens or lens cheap USM (with micromotor), we have to move the lever just play AF to MF manual focus ring.

Lens with USM or not the code will not affect the optical quality, because only signifies USM AF motor system alone. If you are in everyday life often taking a moving object, or a sporting event and need the fastest performance of the system Canon AF lenses, then choose the lens with USM technology in it.

EF lenses and EF-S

EF lenses (electrofocus) are artificial lenses that have Canon EF mount, so must be compatible with EOS cameras. EF lenses can be mounted on Canon EOS film SLR camera body (35mm) and in the body of any digital EOS, either with the sensor full frame, APS-H and APS-C. EF lenses now has many variants of both types of prime (fixed) or zoom. Even the luxury-class lens from Canon is also widely produced the lens with the code L-series (luxury), which is characterized by a red ring on the end. L series lens has excellent optical qualities and ability to hold thanks to the weather disturbance weathersealing therein.

In 2003 Canon launched the EOS 300D digital SLR (Digital Rebel) with kit lens EF-S 18-55mm. This is the first time introduced the EF-S lenses in Canon's history. EF-S lenses have a diameter image circle is smaller than EF lenses, designed specifically for DSLR with APS-C sensor so that the EF-S lenses can not be used for the EOS 35mm film camera. As for the lens EF and EF-S mount basically have the same shape and also contacts the same electronics, so EOS Digital cameras with APS-C sensor can be fitted with EF lenses (not EF-S lenses). But EF-S lenses are not properly mounted on the EOS Digital camera with a sensor larger than APS-C sensor because although it can be used but will produce a black circle on the edge of the image (vignetting) for EF-S lens diameter is smaller.

The letter 'S' on the code itself EF-S stands for Short (back focus), mean EF-S lenses have a much closer distance between the lens with the sensor.

Now available in the market and also a lot of EF lenses EF-S. If you plan to have a DSLR EOS with full frame sensor like the EOS 5D Mark II, then seek only EF lenses only. But if you feel quite satisfied with EOS DSLR APS-C sensor like the EOS 550D, EOS 60D or EOS 7D, the EF-S lenses can be an option.

All about the Canon EOS DSLR cameras

For you lovers of the Canon DSLR, or who are planning to buy Canon DSLR system, if you already know the ins and outs of the Canon DSLR? How does the concept of EOS and EF mount, like what the auto focus on Canon cameras, what difference EF lenses and EF-S, and much more. This time we make a special article that discusses the full Canon EOS DSLR just for you. Happy reading ..

The origin of EOS cameras

EOS stands for Electro Optical System, which means an optical system having an electronic circuit. Canon first introduced the EOS film cameras in March 1987 with the launch of the EOS 650 with the ability to auto focus. EOS cameras have an EF mount, so lens designed specifically for Canon EF mount with the name of Canon EF lenses, and all this must be compatible EF lenses with EOS cameras.

EOS Digital Camera is the first of Canon EOS DSC 3 with 1.3 MP CCD sensor (in collaboration with Kodak) and an important stage in manufacturing the current Canon EOS could eventually produce their own EOS cameras with the launch of the EOS D30 in 2000 with a resolution of 3 MP CMOS sensor . As a processor of the EOS Digital, is used DIGIC processor with a name which has now reached the fourth generation.

Canon FD mount before 1987 had only suitable for Canon FD lenses. FD lenses (see example above) can only manual focus and lens FD can not be mounted on EOS mount because of different shapes and sizes. This is different to the Nikon system whereby all Nikon lenses since ancient times can still be installed on the latest Nikon digital SLR.

The transition from the FD mount to EOS mount into Canon historic moments full of criticism and impressed speculative. However, Canon has finally managed to enjoy the results because the transition a success and Canon make it up by producing a lot of special lenses for the EOS EF mount Digital quality.
