Digital Camera

When you hear the word Photography, the first thing that comes is a photo printout. Photography is an activity that results in the captured image of an object. Photography comes from the word "photos" and "grafos" from the Greek. Photos means light, while grafos means painting or writing.

From that sense, Photography can be defined as the process of painting or writing using the medium of light. In general terms, Photography is a process or method to produce an image or picture of an object that is recorded through the reflection of light. Reflected light is then the object on a light-sensitive medium.

Therefore, in its development, Photography is aided by a tool called the camera as a medium to generate the reflection of light on an object. Without light, the image can not be seen on the photo.

In principle, Photography is an activity to help focus light refraction, so that the reflected light can burn medium light catcher.

Medium that had been burned and then produce an identical image with light named lens. Medium combustion process itself is often burning luminitas size medium with the right light, so that it can produce photo-sized lens fitting.

To generate the appropriate light intensity in an image or photograph, use a measuring tool called light meter. Light meter serves as a measure of the intensity of illumination on the camera. After getting the right size and appropriate lighting, a photographer who is an expert in the field of Photography can adjust the intensity of light with several combinations of light.

The combination of light in Photography, there are several kinds, such as the combination of the ISO / ASA or ISO speed, aperture (aperture) and shutter speed (speed). This light combinations are often lumped together and produce other combinations, such as a combination of ISO, diaphragm and Speed is referred to as a display (exposure).

When planning the budget for your new digital camera, include the cost of an extra memory card. The cards that come with your camera aren't nearly enough memory to take the number of pictures you would like to take, so get a bigger card right off the bat.

A 3-megapixel camera should have at least a 256 MB card; a 4-megapixel camera needs at a minimum a 512 MB card. Any camera with 6 or more megapixels should have a 1 GB card. This will eliminate the possibility of ever missing a shot because your memory card is full, or even worse, having to choose which photo to delete because you have found one more that you just have to take!

Being able to shoot at your camera's highest resolution is another important reason to have a massive memory card. Spending money on a 6-megapixel digital camera should also include shooting with all 6 megapixels!

Another thing to remember is to shoot at the camera's highest compression setting, too. Squeezing more images onto your memory card by shooting at a lower resolution and with lower quality compression settings will only cause regret later. You never know when you will shoot the next great photo. (Do you think the photographer left home that morning knowing he would photograph the nurse kissing the soldier? That photo turned out to be the most well-recognized photo taken at the end of the war!)

Don't chance missing a great shot with poor quality. Another thing to remember is that the lower the resolution of your photos, the smaller the print will have to be to remain clear. No posters can be made with a 640 x 480 resolution. Not exactly what you will want to display at your first gallery showing!

Now, the camera is so close to our lives. If when we go to a place or an event, we would almost certainly bring a camera to capture the moment in pictures.

However, many cameras are still too large to fit into pants or shirt pocket. Therefore, we need a camera bag. Moreover, if we are equipped with camera equipment other equipment, such as data cable, lens replacement, lens cleaners, and others.

In order for our camera safe from damage in the bag, then we need to choose the right bag and the right way to use it anyway. Here are tips on how to choose the right camera bag.

1. Bag Size to Fit

Get a camera bag with the right size. Choose a bag that is capable of carrying camera equipment or accessories at the same time. You may not always use all the accessories, but you also never know when to use it. The best way is to bring all the complementary accessories in a single bag.

2. Choose a bag with a lot of space

One characteristic of a good camera bag is to have plenty of space. This is to store the parts separately camera. If you remove the lens, remove the battery, and then store the rest in a single space in the bag, it was a big mistake. Because of the time taken, camera parts will rub against each other directly. This could result in damage.

Instead, store the parts of the camera separately. For this reason, a camera bag with plenty of space is more advisable to choose.

3. Made Bags and Strong Roped

Bags should be roped sturdy, but not stiff. Strong rope would avoid the possibility of breaking up when the bag was taken. So it is with the material. Materials are good not only resistant to wear and tear, but also resistant to scratches. Leather bags with pretty good in this regard.

4. Cover and Aperture luxury

Good camera bag should also be easily opened and closed easily anyway. That is, the access to get / take it easy, as well as access to store it back in the bag.

For easy and convenient, hook & loop method is often used. But to get the lid and opening the safe, strong zippers also often be an option. Zippers are used when you are not actively using the camera.

5. Waterproof

Make sure that you choose a camera bag impervious to water. If you are in contact with rain or other matters relating to the wetness, keep your camera safe. Check every room in the bag. Usually waterproof bag lined with aluminum foil or the like. Also make sure there are no other material, such as buttonhole, which can be penetrated by water.

Hopefully by choosing the right camera bag, you can secure the camera from damage. The price of the camera is not cheap. Maintaining that there is always better than buying a new one. Congratulations choose!

Sony has almost not been too active in the world of digital cameras for the serious hobbyist photography. But now Sony rose, with the launch of several cameras to address those needs. All new products are launched Sony is not a DSLR, but like a DSLR.

As with Sony A55, Sony A77 and A65 latest technology also uses SLT (Single Lens Translucent). SLT is a technology with a transparent mirror. In contrast with DSLR cameras using mirrors and prisms. Even so, the SLT technology has advantages in addition there are also disadvantages.

The main advantages of the camera Sony SLT A77 and A65 are able to shoot in a row quickly. Sony A77 can shoot 12 photos per second. Meanwhile, the Sony A65 can shoot up to 10 pictures per second. Another advantage possessed, namely auto focus you can follow the subject while recording video. In contrast with DSLR cameras that can only rely on manual focus.

Sony SLT A77 is a camera that does not have the OVF (Optical Viewfinder), but the EVF (Electronic Viewfinder). The advantages to be gained by using the EVT is the resulting image is almost the same as the original object. Even so, the lack of EVT is when used for shooting in the dark, the image quality is lowered.

Actually SLT technology is not new, but has been introduced Sony A55 and A33. Then what is the difference between A77 and A65? The difference is part of the camera body more robust, better quality EVF, has two LCD screens, speed camera, and the image resolution increases to 24 Megapixel.

24 megapixels is currently the highest resolution for class A77 camera. But this is not just a good impact, but also bad. By using the 24MP, the magnitude of image resolution will be sacrificing picture quality at high ISO. However, if you frequently use the ISO 100 almost every time, it becomes an advantage.

When concluded, this camera has the advantage in speed and auto focus. But its shortcomings, this camera is very wasteful in terms of battery usage.

Now it is time to select the type of digital camera SLR or SLT as desired. Remember, in choosing a good note with the utility or benefits gained by using the camera.

Such is the world of photography related articles around the camera with SLT technology. Hopefully the information presented is useful for the readers.

Currently, developments in the world of photography more rapidly. This is evidenced by the many young people who are interested to explore the world of photography. For that, you should first know the various types of digital cameras.

As is known, the type of digital camera is divided into two, a SLR camera and a DSLR. Choose the type of camera to your liking. This is because, there are interested plunge into the world of photography is only a factor of desire, not a hobby. Actually, both SLR or DSLR camera is a fundamental difference in the system just works.

SLR Camera

SLR (Single Lens Reflex) camera that has a different working system with a DSLR. In these types of cameras are not an ISO option. This is because, the ISO has determined automatically casing made of metal films.

SLR cameras can be said to be simpler than the DSLR. Electronic system only works for setting the automatic composition of the photo. Even so, sometimes by professional photographers the auto setting is often deactivated.

In SLR camera image data storage media stored on 35MM movie, so it is not necessary digitization process. In addition, images can also be viewed directly on the outcome of the film. If you want more photo processing, film reels this is brought to the laboratory for washing prints in print or scan.

Thus, the use of SLR can be said to be simpler than a DSLR. If for DSLR type camera, you need a computer and software to transfer photos from a DSLR to a computer. That way, the image can be through the editing process.

Of the many differences, SLR and DSLR also have similarities. Similarly, the object image retrieval systems that work using a single lens. The lens is useful for targeting and delivering shots to the film (SLR) or Image Sensore (DSLR).

The Presence of SLR Camera

Many have pointed out that the Digital SLR Camera has ruffled the world of professional photography. This is because, the camera can be used easily in the hands of amateurs. Cheap photo can be formed into beautiful photos with the help of digital imaging, when the post-shooting digital SLR use.

Digital SLR, in other words, Digital Cameras Single Lens Reflect is the last revolution of the world of photography. Uniting two digital cameras with good strength that of the SLR type camera. The use of replaceable films.

The amateurs were able to shoot well because they no longer fear when the photograph was unsuccessful, they just use the delete facility then learn again. The facility was made possible because digital cameras use CMOS, replacing the silver film plate.

Type of SLR Cameras

For photography lovers who want to raise the level to a higher level, it was necessary to have this camera.

For those of you who have a hobby of photography will get more satisfaction, when using this digital SLR camera. Skills in photography will be felt, if this camera is used pleh professional photographers. Thus, it can easily produce high picture quality and high value.

The Digital Camera is a tool to create an image of the object and refracted through the lens to the CCD sensor. After that, the results are recorded onto digital storage media. This digital photography tool works without using film.

To capture an object, the photographer can easily snap a picture without using the window view. LCD screens mounted in the rear view camera is a replacement window. This camera uses internal memory or external memory using a memory card as storage medium.

Components

1. Sensor is a photographic tool that serves as a sensor image capture is also known as a CCD (Charged Coupled Device) and CMOS (Complementary Metal Oxide Semiconductor) yangdengan millions of pixels in it. This sensor chip form, with the increasing number of pixels captured by these sensors will be more detailed images are also generated.

2. LCD screen is a small screen on a Digital Camera are used to view snapshots captured by the CCD sensor. Well, the picture of the LCD screen will be more accurate than the results of conventional photographic tool. The LCD screen is also used to help view the photos instantly after pictures taken by the photographer so as to facilitate correct photos which one is better.

3. Storage media is media that can be either compact flash, memory stick and others. Generally it has the capacity of storage media in a large number of customized memory capacity owned. The capacity of the image is determined by the capacity of each resolution of the resulting image. The higher the resolution, the larger CCDnya also the space for image storage.

4. Digital Pocket Camera is a tool that uses an automatic photographic image capture formats with small size and light weight sehingag very easy to carry anywhere.

The character of digital compact cameras is the same as the manual or use the film medium, the camera is equipped with many amenities such as to handle the lighting looks weak and focus on the top or close up.

Digital Cameras certainly have weaknesses, here are some disadvantages of this photographic tool:

• Have a long time delay when recording an image.
• Have limited use to manage objects in a professional manner and a certain artistic treatment.
• Has limitations in the absence of supporting accessories such as lenses or filter exchange.
• Its function is too simple and monotonous, even for the latest type of compact pocket camera also has the facilities and functions similar to the type of digital camera types LSR.

5. SLR (Digital Single Lens Reflect) Camera.

Who does not know Adobe Photoshop? If you hear the word photography, the term is also usually immediately comes to mind. There are photos, no photo editing. Not only the fans of photography, graphic designers also often use this software.

Adobe Photoshop is an image editor software made by Adobe Systems Incorporated, a computer software company from America since 1982, based in San Jose, California, United States. The inventor, John Warnock and Charles Geschke, previously worked at Xerox PARC, and stop when they decided to develop and sell the PostScript language description.

Photoshop is a special software for editing or correcting the results of a photo or image and create or add effects to photos / images. This device was first introduced as Adobe's flagship product in 1989, which is a graphical correction program for the Macintosh. This application was created by Thomas Knoll and John Knoll in the early summer of 1988, which was later purchased licensed by Adobe Systems in September 1988.

Adobe Photoshop and Adobe Acrobat referred to as the best product ever produced by Adobe Systems to gain appreciation of International Standard, ISO 32000-1: 2008. Nowadays these devices have been widely used by professional digital photographers, graphic designers, and advertising companies. The resulting popularity of the company which includes the ranks of pioneers is still difficult to compete with, so Adobe can be regarded as a market leader (market leader) for image processing software or image.

Adobe Photoshop Features

Initially, Photoshop designed by Thomas Knoll, PhD., a graduate of the University of Michigan who created the program to display an image format or display of black-and-white or grayscale into a monochrome display. This program, called Display, then ogled John Knoll, his brother who worked at Industrial Light Magic, and it is suggested that perfected to become an image editing program or corrections.

They then collaborated and created Photoshop. Now, along with innovation, this software can also be used to correct the images, add effects or filters to the image, change the image, even producing images for the World Wide Web. Some of the final version also features additional applications, namely Adobe ImageReady.

Photoshop has a close relationship with some software for media editing, animation, and other Adobe authoring. Native Photoshop file format (PSD) can be exported to and from Adobe ImageReady. Photoshop can accept the use of several color models, as follows.

• RGB color models
• Lab color models
• CMYK color models
• Grayscale
• Bitmap -Duotone

Version of Adobe Photoshop

In 1990, Adobe launched the first series of this software to the public, with labels Adobe Photoshop 1.0. Along with the development of its management, renewal programs continue to be planted on this application until Adobe continues to launch new versions for the broad market.

From the start version 2.0 (also known as Fast Eddy code), version 2.5 (codenamed Merlin for compatibility on the Macintosh, and Brimstone for Windows), version 3.0 (codename Tiger Mountain), version 4.0 (codenamed Big Electric Cat), version 5.0 ( codename Strange Cargo), version 5.5 (codename still Strange Cargo), version 6.0 (codenamed Venus in Furs), version 7.0 (codename Liquid Sky), and version 7.0.1.

Photoshop CS is the name of the eighth version of this application. CS first version was released in October 2003. Owned real difference is the version of Adobe Photoshop earlier than this version is able to process raw or raw format media from a variety of digital cameras and also supports extensive corrections for 16-bit color images.

Ninth and subsequent versions of Adobe Photoshop CS continues to use the term (which is an acronym of the Creative Suit), and followed by the serial number on the back, which is Adobe Photoshop CS2, Adobe Photoshop CS3 for the tenth version, a version of Adobe Photoshop CS4 for the eleventh version, and Adobe Photoshop CS5 for twelve versions, and the latter was released on the market in March 2012 is the Adobe Photoshop CS6.

Version nine was released in 2005 and marketed under the name Photoshop CS2. This version has some extras, such as selecting multiple layers and warp, curve version of the transform tool and the color replacement tool.

Adobe also provides filters reduce again (to reduce the grain) for photography enthusiasts. This filter helps to optimize photo taken during low light conditions. Photoshop CS and CS2 wear fur as icons and shape identification.

On December 15, 2006, released a beta version of Photoshop CS3 to CS2 users. The logo is different from the previous version, the typefaces with the letters Ps shaped white and blue gradient background.

Adobe Photoshop CS4 (Adobe Photoshop Creative Suite 4) is a new version of Adobe Photoshop program issued by Adobe Systems Incorporated. CS4 is available in two versions and is a refinement of previous versions.

While Adobe Photoshop CS6 even support for video editing or correction. The advanced features in this version are known to straighten tool which by this equipment the user can draw a straight line at any angle on the image, and the straight line will automatically orient and adapt itself to the media image. The line can instantly change the horizontal, vertical, or oblique, according perspective drawing.

File Format

Adobe Photoshop capable of reading and writing images with raster and vector formats like png, gif, jpeg, etc.. Some typical file format owned Photoshop is as follows.

• PSD (Photoshop Document), which is the format that stores images in the form of layers, including text, mask, opacity, blend modes, color channels, alpha channels, clipping paths, and duotone settings.
• PSB, which is the latest version of the PSD is designed for files with size more than 2 GB.
• PDD, which is another version of the PSD and is only able to support software features PhotoshopDeluxe.

Tools

In Adobe Photoshop, the "Tool" is a tool that serves to help users in editing. Here are some of the tools available in Photoshop.

• History Brush Tool
• Eraser Tool
• Path Selection Tool
• Direct Selection Tool
• Pen Tool
• Shape Tool
• Brush Tool
• Audio Annotation Tool
• Eyedropper Tool
• Measure Tool
• Text Tool
• Hand Tool

Impact to Photography Industry

The development of software for Adobe Photoshop is the correction of digital images greatly affect the photographic industry, namely the creation of photo retouching and photo manipulation or photo creation.

Maximize the end result may be less than perfect photos like a professional photographer, to manipulate or change the total picture until the final result is more imaginative, is now able to be done by an amateur.

Photoshop has become the standard in the industry at the time of the digital revolution. Many photographers are now "requires" the use of this software, given its function is really needed and value added.

However, there is still a photographer who prefers shooting as perfect as possible of the need to correct the image again, which takes more time. Especially for fans of analog photography. Regardless, the existence of Adobe Photoshop gives a color of its own in the photography industry and the people that work in the world-creations of imagination images and photos.

One of the advantages of a digital camera that can not be found in an analog camera is the ability of digital camera to connect directly to the computer. This is certainly an advantage for the photographer to be able to select the photos stored in the camera. They can choose the best photos or can edit before printing.

Having selected the best photographs, the photographer will make the transfer to the computer. Its required special interface, so that the camera and computer can communicate with each other. Commonly, known term is the data transfer.

There are several ways that can be done to transfer the data from a digital camera to a computer. Maybe not all the way is owned by a digital camera, but at least there is one way that has been provided by the digital cameras that can perform data transfer to a computer.

• At the start of production, a digital camera using the serial port on the computer. The weakness of this connection is a slow time of data transfer. Currently, connected via the serial port is not used anymore.
• Using a USB (Universal Serial Bus) connection is a more practical and faster than the serial port. USB connection is becoming the most widely used today and has become the standard interface of data transfer between a digital camera to a computer.
• Using a FireWire connection. This connection is copyright Apple Inc.. known as IEEE 1394 interface. The advantages of this connection is also the same as the connection using the USB interface.
• Using a USB PTP (Picture Transfer Protocol) connection. This connection can be used as a way to connect a USB connection in addition to MSC (Mass Storage Device). Currently, some computers have provided two ways that connection.
• Using a Wireless connection. Currently, some digital cameras have been equipped with a wireless connection to connect to a computer. Practical because it does not use a longer cable. Although wireless, the speed of data transfer is not in doubt.
• Using a storage media reader tool called Card Reader. Storage media in a digital camera will be released and then fed to the Card Reader. Card Reader will be connected to a computer so that the data derived from a digital camera can be opened in the computer. Today, the use of Card Reader has become a standard alternative because this tool is able to read various types of storage media, and enables high data transfer rates also.

One of the advantages Card Reader that no other connection is the data transfer takes place when the battery power is not needed. This is very helpful if a photographer had forgotten to bring a spare battery.

Advances in technology also affected the camera world. Nowadays almost all digital cameras have the ability to record a direct transfer to a printer without using a computer. The photographers only need to choose the best photos on the camera's LCD screen through them, then just connect to the printer (wired or wireless) and print directly. Practical isn’t it?
