How to iOS: AE / AF locking in camera app of iPhone

On the iPhone, the camera has an auto focus (AF) and Auto Exposure (AE) function. When the camera moves slightly he will automatically adjust focus and exposure so that you do not overexposed photos or videos get. It is also possible to use the auto focus lock. It can be useful when shooting a person and if you want to create a blurred background which gives a nice effect.

The function AE / AF-locking has been around since iOS 4 are present, but is not yet known to everyone. Using the camera lock will not automatically focus on objects, but only on a selected object and then the exposure is well adapted.

Lock the focus is very simple. Normally when tapped with your finger on the screen with the camera app you see squares appear so that you can focus.

To the AE / AF lock to keep your trigger finger a few seconds on screen. You see a few times the square appearance. After a few seconds remove your finger from the screen and there above the shutter button, AE / AF lock. Now the focus is locked and will not auto focus.

A very useful feature, sometimes it is not nice that the camera will focus when suddenly you do not want. The lock can counter this. The lock works on both the photo and video camera.

AMD FX-8150: Bulldozers enters the market [Test]

TEST Bulldozer is something most tech-savvy heard of. It is AMD's new architecture, built from the ground up, which is the first time since 1999 when they introduced the Athlon series and the K7 architecture, all processors until now been based on. Discussions have been many, so join us in our deep dive of AMD's new performance chip Bulldozer.

When we reviewed AMD Llano, we said that 2011 would be AMD's most important year ever. It is something we stand by today. But in addition to an important year, there has been a very eventful year. AMD chose unexpectedly that their CEO Dirk Meyer, who got the company back on its feet, had to go. Finding a replacement took over six months and the Chosen for the task to bring in AMD in the future, where Rory Read. Read has a background at IBM where he worked 23 years and five years from Lenovo. As COO of Lenovo, he was one of the main people behind the company's success in Asia.

In late September, although Rick Bergman, the company that was their product manager in the consumer market. He was a veteran from ATI, which certainly many old ATI fans knew who it was before AMD bought up the company. Speculation was hot around that he had to leave involuntarily. But it turned out, he left to take a CEO job at Synaptics, which develops touch-products and user interfaces.

Besides having lost two great icons of the company, so today it is launching its third new architecture in less than a year. December 2010 launched their first fusion product: Zacate based on their new Bobcat core and Cedar graphics core. In June came the much talked-about Llano, which is built on AMD's older Stars-cores and Redwood graphics. Today, the company perhaps most anticipated architecture for years, namely the bulldozer that is built on an entirely new processor core. Bulldozers are unlike Zacate and Llano processors without built graphic.

It's certainly not often a product has received so much attention, and AMD has also managed to keep the details secret until the very end. With Bulldozer architecture takes aim at the upper-middle class, and the lower enthusiast segment with what they call the world's first consumer processor. Bulldozers are not only important today, but it is the basic AMD will use additional CPU architectures and APU's. It thus becomes their new K7 who will lead the x86 market underdog into the future.

It is now time to begin the largest plunge in the Bulldozer, the company's most anticipated processor architecture ever.
