Too much television (TV), it can increase the risk of overweight (overweight) in children. The statement is based on research in the Archives of Pediatrics and Adolescent Medicine. However, it only applies to the condition of children with parents who suffer from obesity.
In that study, the group of children of parents with normal weight indicates the length of time watching TV does not affect their weight gain. In addition, it is believed also that parent weight status is an important factor in the relationship between TV viewing and child weight.
The study was conducted through interviews in the home or over the phone, which involved 1,483 children aged 6 to 19 years and showed that parental obesity is directly related to the risk of overweight in all the children, except in boys aged 6 to 9 years. Furthermore, for boys aged 14 to 19 years and girls 10 to 13 years old with parental obesity, overweight risk increased with increasing number of hours spent watching TV.

Healthy baby teeth are important for children to learn to chew, speak clearly, smile full of flavor themselves, and to ensure that the permanent teeth will appear correctly.
Dental disease is the most common disease that affects children, and reports from the Centers for Disease Control and Prevention says that 28% of them have cavities in milk teeth.
If your child has never aged 1y dental medicine, make an appointment now .American Academy of Pediatric Dentistry (AAPD) and the American Academy of Pediatrics recommends that children’s teeth examined for the first time after the age of 1 year. Examination will not be long and the doctor can quickly find early signs of tooth decay and plaque formation. The doctor will also make sure the teeth, mouth, esophagus and throat child correctly formed. When children suck a pacifier, your doctor may ask you to get rid of that thing so he was 2 years old in order to prevent problems that could potentially arise.

Some time ago blogs legendary photographic agency, Magnum Photos, created a 35 article contains advice to budding photographers magnum photographer (my original article was not linked). Here I extracted the contents of the 35 counsel with my translation simplify and shorten mine. To read a longer version of the original, you can download the original article in PDF format here (English).

Here to-35 this advice:
Abbas: “Buy a pair of comfortable shoes, and begin to fall in love”.
Alex Majoli: “A lot of-a lot of reading literature and as little as possible to observe the work of someone else’s photos. Work everyday even without assignments or money, work with discipline for yourself and not for others. And collaborate with people you admire. ”
Alex Webb: “Shoot because you love him, and because it is the greatest gift you shoot itself”
Alec Soth: “Try everything. Photojournalism, portrait, fashion … anything. You will not know which one fits before ever tried ”
Alessandra Sanguinetti: “I agree with Bob Dylan: always keep your head and do not forget to always carry a light bulb that good (idea)”

When you shoot an affluent light, autofocus system camera will never trouble locking focus. But you try to go to a well-lit, the autofocus system will start looking for trouble and lock the focus point.
Here are 8 tips to keep your camera fast and accurate autofocus lock even if you shoot in low-light situations:
1. Use the Focal Point in the Middle
Whatever brand your DSLR camera, when shooting in a dimly should use a focal point in the middle frame. Why? as the focal point at the center using a cross type sensor types that work more quickly and accurately than any focal point in your frame, let alone that there is a side area.
2. Take advantage of the AF-Assist feature
When trouble locking focus, you can enable this feature through the AF-Assist AF menu in the camera will turn on a small light in front of your camera’s autofocus system that can help. To use the Af-Assist, you should use the autofocus AF-Single mode Continue reading “8 Tips to Improve Speed and Accuracy Autofocus in low light conditions”
Say you’re traveling or walking while carrying a camera, while not unexpected will always appear a very good moment to be photographed. Moments like this take a moment and will not happen again. When you look at the moment and immediately photographed in order not to lose the moment, there is a chance your photo will produce fuzzy or blurry.
Why blur? many reasons, one of which is that these moments occur in areas that the light conditions are not perfect so we slow shutter speed, say 1/60 sec. With a shutter speed like this while we are shooting is not under direct sunlight, your photos are guaranteed to be a little blurry. How do the trick?
To avoid it, the trick is to enable the Auto ISO that is on camera. With the Auto ISO setting: ON, the camera will automatically increase the ISO when the shutter speed the camera is slow. When Auto ISO is on, we can even determine the minimum shutter speed and ISO to determine the maximum. So as if we tell the camera: “Hey camera, so the shutter speed below 1/125 sec, ISO increase, but not too high ya! maximum ISO 3200 alone! ” Continue reading “With Auto ISO, Your More Sharp Every Time”
What is Bulb Mode?
There is a special setting in almost all DSLR cameras and mirrorless cameras, which is or BULB BULB mode settings. This mode is usually marked with a notation in your digital camera. Well now look carefully control your camera, if there is a letter B there means he is responsible for activating the bulb mode, turn up at B and if the LCD is written bulb then you are ready to shoot bulb.
Jetty by Giles McGarry (2 min exposure)
Bulb mode is a special setting, where we can use a shutter speed above 30 seconds, we can even use a shutter speed as long as we want. Range Maximum shutter speed on camera DSLR usually stuck in 30 seconds, now with Bulb mode, we can use a shutter speed well above that.
The word bulb emerged since ancient era, grandparents predecessor photographers use air bubbles in the rubber (bulb) that pressing the shutter mechanism that opens.
Bulb Mode When Used?
Some shooting situations that require the use of bulb mode, among others:
When photographing fireworks
When you are photographing trail of light: light cars and tracks star
We will take pictures in the dark of night using a small aperture setting range of f/11 to f/22
When you want a photo light painting (see photo light painting tips here)
When you want to make a picture of lightning
Sometimes when photographing celestial objects (astrophotography)
In essence, Bulb used when you want to take a loooong exposure over 30 seconds
Milky Way by Daniel Taylor (45 second exposure)
What Are Needed In Using Bulb Mode?
Some items and essential in using bulb mode:
Tripod mandatory, unless you want to make an abstract picture that no one knew what it meant
Use Remote Shutter Release with locking mechanism
Timer, just use the timer on your smartphone
Try to use the ISO as low as possible
Battery backup, photographed with long exposure to minute drain camera batteries, so prepare reserves
Snack or friends chat or twitter app on your mobile phone while waiting expsoure a long finish, this heheh kidding
If you have started studying the manual exposure setting on the camera is available now is the time to play around with the settings there. In this article we will discuss how to freeze the motion (motion freeze) using shutter priority mode.
Just refreshing, as has been written before the shutter speed is how long the sensor to see the amount of light (aka exposure)
Broadly speaking, accelerate or slow down the shutter speed to produce images that are different. There is no right and no wrong, it all depends on the message that we want. Super fast shutter speed allows you to freeze the movement of birds flying, slow shutter speed makes panning you can produce images that show movement
For Super Fast Movement
The faster you want to freeze movement in an image, the faster the shutter speed is needed. In the example photo above, the selected shutter speed is very fast which is equal to 1/5000 sec. Shutter speed as fast as it takes for the surfers movement is very fast, while I was on the boat also moved closer, so either the object or the camera moves relative to each other. For that camera set on shutter priority mode and auto ISO, and focus on continuous position
I set the shutter speed in the first position of 1/5000 so that the camera choose the aperture of f/2.8.
How to movements that are not as extreme as that?
This photo shows people who are jogging in the morning is quite bright. Photographers need enough shutter speed is (1/400 sec) and it was enough to freeze move. Why did not need as fast as the previous example? because the movement of people jogging relatively slower than surfing, plus as a photographer in a stationary position, and because the field of the object (the run) are relatively parallel to the focal plane of the camera (do not move close as an example surfing).
Okay, one more example:
This picture requires a shutter speed of 1/800 sec. I was in a stationary position and a flying bird was trying to slow down the movement, but the distance from my bird close enough (about 6 feet) so I need a shutter speed of 1/800 sec.
There is no official benchmark how shutter speed required for any situation where we want to freeze the motion. What is clear you have to direct practice, but there are some points that can be drawn from the three examples above.
Broadly speaking, in order to freeze the movement you need to consider several things:
The speed of the object itself, the object accelerated faster shutter speed is needed
Relative velocity we (photographers) to the object. If we move closer the shutter speed required is also higher
Distance of the object. The closer the object to the photographer who takes the shutter speed is also higher
Focal length of your lens. The more the focal length of your lens, the faster the shutter speed is needed.
Okay, good luck!
A lot of questions sent via the Contact page on why you produce photo until now still not as sharp as expected. Now that your image is always sharp, the most important thing you should know is what causes your photo blur.
If traced-trace the logic and practice in the field, causing blurry photos are not sharp alias can be traced from the 5 things below. Just an assumption, assume that we are now using a 50mm f/1.8 lens.
1. Fast Shutter Speed Less
An important rule when you are holding the camera is not to use a shutter speed slower than the focal 1/long . So when shooting with a 50mm lens, you should use a shutter speed of 1/60 or faster, and even then with a record you can hold it very stable.
The longer focal length lens, the faster the shutter speed you should use. When using a 200mm lens, you at least use 1/250 sec. Telephoto lenses not only magnify images of objects, they also make it look more visible blur. It has a lens with IS and VR would also help.
2. Note Movement Subject
Rule number 1 above okay if you shoot stationary objects and the photographer is also silent, but if we picture is a car on the street or a bird flying or we were photographing was also engaged, of course only with focal 1/long still photos still look sharp.

In photography, the word “stop” often we hear and read. No, not stop it, not stop it means stop. Stop here is a term in photography. Examples of its use might be something like this: “Because of his picture look over, I was down one stop”, well like that.
If until this moment, the word stop in photography still make you confused, please refer to this brief.
Stop in photography about meaningful change the amount of light received by the sensor / film thus affecting exposure photographs. Add a stop means more light 2 times, plus 2 stop brighter means 4 times. Subtract one stop means darker half times. One stop means changing the amount of light as a multiple of 2.
As you know, the amount of light received by the sensor we frontage exposure. And ride one stop means increased exposure 2 times. Actions increase or reduce exposure can be done by changing any one or combination of the three elements that make up the triangle exposure: shutter speed, aperture and ISO. (Further described in this article: Understanding Exposure Drafts).
Rather abstract huh? okay so obviously a parable. In room Say you have 4 100 watt bulbs and fourth turns. Because the stop was illegal change of light, then down one stop means you can turn off two lights so that only two lights. While riding one stop means you have to take 4 lamp again with the same wattage. In this case, the room is a sensor in a digital camera is light moreover its exposure.

The eyes are the most important asset in photography. We put together a picture of the eye and vision ultimately captured photos also enjoyed the eye. The mistaken assumption that the quality of the image is determined only by the techniques and tools. It is true, but only partly. Because the eye is the vision, the actual practice how to view and composition of images, we can actually improve our photographic skills dramatically, all without capital other than the will and the camera that we already have.
When the ability and the art of seeing, recognizing and compiling an object image is honed, the picture we’re more interesting than before. The things that seem boring and ordinary, hands photographer with a sharp eye can be transformed into a very attractive picture. Well this article will discuss some basic tips to practice the art of seeing alias foresight to train your eye to recognize images of objects and translate them into a photo with interesting composition.
Here are some initial steps:
Take a picture of simple objects, such as “line”, “circle” or “box”. In one week you just force yourself photographing this object. If from the beginning you specify will only be taking photographs with a line object, for one week take time each day to simply photographing the line. Forget the object pictures, focusing on the line: the line road markings, line cord, line-storey building. Similarly to other simple objects.
