Lens Size Make Some Different

Everyone has at some point had the same problem: no matter how much you try to be consistent with your camera face, some pictures look great and others look awful.

The difference is in the level at which each lens distorts the natural image, bending light so that the three-dimensional image is represented as a two-dimensional photo.

Depending on the lens' focal length, the image will deform and affect how the image looks in photos. The shorter the focal length, the more field of view you can capture. That's why something like a 'fisheye' lens (15mm) distorts objects dramatically.

A larger lens (say 350mm) will flatten and widen the face of the subject. Experts say a 135mm lens would produce the best, most consistently accurate results. But even then there's an element of risk. If nothing else, you can now give your friends a decent excuse as to why you always look bad in holiday snaps.

Profesional Cameras In Your Pocket With Sony NEX-7

Sony has announced the much leaked NEX-7 enthusiast-targeted mirrorless interchangeable lens camera. It packs a 24MP APS-C CMOS sensor and 2.4M dot OLED electronic viewfinder into its magnesium alloy body and yet still finds room for a pop-up flash and Alpha hot shoe. This unique combination of sensor and processor assures ultra-rapid shooting responses, plus flawless image quality with ultra-low noise when shooting still images or Full HD video. Extending from ISO 100-16000, the ultra-high sensitivity range makes it easy to capture clean, low-noise images in dimly lit interiors or at dusk. Responses are accelerated further by a shutter release lag of just 0.02 seconds – the fastest of any interchangeable lens digital camera in the world. Quick, precise AF is enhanced by new Object Tracking that keeps accurate focus lock on a selected target, even when it’s moving in the frame. The NEX-7 offers quick, easy control over creative settings via an intuitive new TRINAVI control. Two control dials on the top of the camera are complemented by a control wheel. 

Pushing the navigation button cycles quickly through various shooting modes, allowing enthusiasts to make custom adjustments and control images with the flexibility of a DSLR camera. The NEX-7 uses a new shutter arrangement, with an (optional) electronic first curtain. In other words, the camera no longer has to close the shutter then open it again to start the exposure, and according to Sony this decreases shutter lag from 100ms to just 20ms. This isn't completely new technology - Canon's live view capable DSLRs have been using it since the EOS 40D of 2007 - but it's very welcome to see it implemented in this type of camera. 

Further indication, if any were needed, of the NEX-7's serious intentions is provided by the co-announced Carl Zeiss-branded E 24mm F1.8 lens (also known as the SEL24F18Z). This offers a field of view equivalent to a 35mm lens on full frame, and places the NEX-7 squarely up against the likes of the Fujifilm FinePix X100 (with its fixed 23mm F2 lens), as well as the E-P3. The NEX-7 will also be sold with a black version of the standard E 18-55mm F3.5-5.6 OSS kit zoom. The NEX-7 will be available in November for $1350 with a 18-55mm kit lens or $1200 for the body alone. Meanwhile the NEX-5N will be available in September with the same kit lens for $700, or on its own for $600.

Sony NEX-7 specification highlights

• All-new 24MP APS-C CMOS sensor (shared with the SLT-A7 and A657)
• ISO 100-16000
• Built-in 2.4M dot OLED EVF with eye sensor
• Electronic first-curtain shutter (cuts response time from 100ms to 20ms)
• 'AVCHD Progressive' 1080p60 HD movie recording with built-in stereo mic
• Tilting rear screen
• Three-dial user interface
• Built in flash and Alpha hotshoe
• Infra-red remote control receiver
• Microphone input socket
• Exposure Compensation
• Autofocus Mode
• Metering Mode (pattern)
• White balance preset (Auto, Daylight, etc.)
• DRO/Auto HDR mode (Off/DRO/HDR, but also Off/ DRO Level 1-5, Auto HDR/ HDR EV spread 1-6)
• Creative Style preset
• Picture Effect
• Quality (JPEG Fine/JPEG Standard/RAW/JPEG+RAW)
• "Not Set (in case you don't want to assign any function to that dial)

Bottom line, the NEX-7's new Tri-Navi interface offers more flexibility and configurability than anything we've seen to date on a Compact System Camera.

The Sony NEX-7 is a Compact System Camera unlike any other yet produced. Up to now there has broadly been two types of CSC: DSLR style and compact camera style, the key difference between them apart from shape, being the inclusion of a built-in electronic viewfinder (EVF) in the former. The NEX-7 is a hybrid of the two styles. It takes the compact styling of the rest of the NEX range as a starting point, but blows it up in size and adds an EVF. In outward appearance its styling and sober black-only finish is reminiscent of M series Leicas and immediately conveys that this is a serious camera aimed at a different and more advanced audience that CSCs have targeted thus far. 

Alpha Mount Adaptor

One of the appeals of the NEX system is that its shallow body enables the attachment of adaptors for pretty much any lens mount. Sony's new LA-EA2 Alpha mount adaptor features its own translucent mirror and AF module so that any Alpha lenses attached to it behave like they do on Alpha cameras, with the superior phase detection AF. But with the right mount you can fit all kinds of lenses, both current and obsolete, and it is envisaged that the NEX-7 will be popular with owners of Leica M series lenses in particular.

The NEX-7 we handled is an early pre-production model and we were not allowed to put an SD card in it to assess to image quality, as there's still some tweaking to be done to the firmware, but from a handling and usability perspective the NEX-7 is impressive. Its discreet form makes it an ideal street photographer's camera. The tilting 921k dot LCD screen facilitates candid shooting but the inclusion of that superb EVF, which we have already seen on the Alpha 77, makes it a great option for those who would never consider buying a camera without a viewfinder.

4 Rules about photography

4 Rules About 

Photography

Before we plunge into the world of photography more deeply, we should know the basic of these photography techniques. Among them is that we must understand the rules about photography.

Here I will describe some rules in photography, including: Composition Line, Geometric Shapes, The Rule of Thirds, Framing Images.

1. Composition Line

The composition of the POI is how we put in the frame so that the concept of balance and simplicity going on there.

Line has an important role as one element supporting the theory of composition. Lines meant here who could have been formed from the angle and position the frame so that the line formed from actual objects, like trees, railroads, power lines and other objects that make up the line.

Lines can also provide an additional effect on the visual and emotional impact of the picture because:

- Additional lines can display a dynamic impression in photos

- A line of photo lovers invited to direct his attention to the area (POI)

- Lines can also create depth (depth) in a composition field.

- A line we can use as well as directions and orientation in the image, etc.

In addition, understand the theory of composition is important because such lines could invite a response from the audience of how photographs They feel and mood from conducting your photos, which then becomes a challenge, how we "use" and "use" lines to draw the attention of connoisseur photos.

For this type of line we can reply "use" in adding the composition of our picture frames include :

- Leading lines,

- Vertical lines, 

- Horizontal lines,

- Diagonal lines,

- Curve lines,

- Perspective lines.

composition of several lines above each can cause different effects in the cause and evoke the mood for photos viewers.

2. Geometric Shapes

With the position of the key aspects of the landscape at the corner of geometric shapes you can help create a balanced composition. Probably the most common and easiest way to do this is to use the 'triangle' forms between objects in an image with three objects in the frame is positioned with one for each side and one center. Geometric shapes used in this way is one technique to get a balance in the shooting to lead the eye into the photo shooting (in the same way with diagonal lines above rules).

3. The Rule of Thirds

The Rule of Thirds will come out more often than others in all types of photography and is one of the first regulation of the composition is taught to students of photography. Although it sometimes feels a bit cliche this may also be a very effective technique in landscapes (although keep in mind that the breaking (and other rules) can also produce images that are dramatic and exciting). Key points in the landscape position is on the point of intersection between an imaginary 'third' dots in the picture and you will help provide balance to the images that you shoot an image focal point and help to really grab attention.

4. Framing Images

Many of us often put the photos in a frame, both frames as a means of displaying images (such as picture frames for wall hung, placed on a table / nightstand or other places), as well as limiting virtual frame image area with the photo paper / other print media .

The benefit of framing the image include:

1. Giving context to the photo

2. Adding a message of the photo

3. Gives the impression of more than photos

4. Creating a point of view of photo

5. Attracting viewers of your photos.

Frame for a photograph can be obtained from any and all objects, including tree branches, mirror, shot through the window, from behind the fence, behind the foliage, behind the gate, even from the person's head and shoulders, and others.

The above rule is not a rule that must be applied in photography. Rules can be used as a material consideration in taking a picture. For me personally a good outcome is determined from the imagination and creativity of each individual. Hopefully this article helps: D

Techniques Photographing Model In Outdoors

For photographing models outdoors, there are several techniques that need to be considered by the budding photographer, among others:

1. Use the camera on the ZOOM position so that the model could be a bit far from you.

2. Do not use the Wide Angle lens at the position (wide lens) because there will be distortion effects, the model looks more broadly.

3. When photographing models outdoors, try to find time when the sun is still soft (8-10 mornings or afternoons 3-5). It is characterized by the shadows under the eyelids or nose and neck look softer.

4. Use side lighting technique, where the light comes from the left or right model.

5. In anticipation of the models that are not exposed to light, you can use the techniques fill in light (fill light). Fill in light engineering is a simple to use white paper or white cloth as a reflector (reflective light medium)

6. For models with body size is, position the camera in the middle of the frame and the high level with the model.

7. For models with heavier body size or wide, try to take a somewhat oblique position or about the right to look thinner models.

8. For shooting outdoors models, choose locations that are not so crowded and the soft background so the model became the dominant look. Background color selection also endeavored to avoid the color red because it tends to make skin color more pale or even bluish - tint.

9. Dedication by the model is important because it will affect the aura of the resulting images, try to make models feel comfortable and relaxed, generally this will be obtained after 30 minutes of shooting.

10. Good communication is important so that the model does not lose the mood, such as delivering a less flattering pose, should be raised only the confidence of the model by saying "Ok .." "Well ..", "Great .. poses next please ... "
