Samsung Galaxy S5 Camera Review

Samsung came up with the latest iteration of their Galaxy S series and called it the Galaxy S5. It is the meanest, most powerful device in the series yet and it comes with a bunch of additions and improvements. The list of features expected from this device was quite long and it wasn’t exactly something dazzling when it came out. It adds features like a fingerprint scanner to make it safer and the heart rate monitor to keep track of your fitness. The hardware is powerful as compared to the previous devices and apart from the basic hardware, they have worked on the camera as well.  





 Sensor

The Galaxy S5 has got a camera with slightly higher resolution as compared to the Galaxy S4. It has an f/2.2 lens and an equivalent focal length of 31mm. the camera resolution is up to 16 from 13 which doesn’t seem like a huge upgrade. It is the same story with the size of sensors as well. The size of sensor has gone up slightly from S4’s 1/3.06 to 1/2.6 on this. While the sensor is larger, it doesn’t exactly translate into larger pixel size because of the increased resolution. The pixel size is a very mobile-ish 1.12 micron so you might not get an impressive low light performance. It features a new ISOCELL sensor which is something new after the Sony sensors they have been using for a while. The ISOCELL sensor is based on an entirely new architecture. It creates physical barriers between sensor pixels. This helps in reducing the crosstalk. This way you can raise the ISO level without inducing too much noise in the image. They claim that the crosstalk is down by almost 30 percent and the actual images justify their claims.

Phase Detect Auto Focus

You might have heard people talking about the insanely fast auto focus system on the Galaxy S5. Well this is because it uses Phase Detect autofocus. This is something we have seen first time on a mobile phone. In a standard contrast detect system; the camera tries to obtain the best contrast of the area in focus. Rest of the region hasn’t got contrast as good as the region in focus. While this system is effective, it takes a while to obtain a good focus. This is because it first goes beyond point of good focus and then tracks back once it has compared different points. You might have noticed this effect while focussing on your mobile phone. The image becomes crisp and then blurs before it reaches the crisp point again. This system also fails to work properly when the contrast is low. This might happen in case of a very bright or very dark frame. The phase detection system requires separate hardware and can be implemented in different ways. This system has been seen on various dedicated camera and while many of them use translucent mirrors to implement this, there are no mirrors on the Galaxy S5 and it is done with the help of extra lenses. The light being sent to the sensor passes through multiple plastic lens elements. When the focusing element is in the right place and image is in focus, the light from ends of the front lens will converge properly on the sensor. If that is not the case, light from the ends of front lens would not converge properly on the sensor. The phase detection would filter out the light received from these edges to see how much they are off their phase. This helps it determine the exact amount of adjustment required to get a sharp focus. The focusing element is moved and as soon as the light information is correct, it will signal to notify that the image is in focus. This system eliminates the need of going beyond the focus point making it faster than contrast detection. It can also perform better in condition where the frame has got low contrast. But the issue here is that it relies on specific lenses that are present above the sensor. This limits the number of focus points that you get. Samsung has kept it a secret about how many auto focus points it has got.

Image quality

While Samsung has done some good with the focus thing, they have left out the optical image stabilisation. Instead it relies on some software method for that. The photos that you obtain are crisp in daylight. If you compare it to galaxy S4, the differences are not very prominent but still they are present. The photos are slightly less sharp in the corners but that is something you might not notice at all. Unlike the Galaxy S4, it doesn’t increase the sharpness much. While focusing, it uses both phase and contrast detection to speed up the process and it is a good deal faster than other high end devices. The difference is very prominent when focusing on close objects as compared to objects far from you. In low light, the camera should be a star because of the normal pixel size. Well they have taken some measures to ensure that it performs well. In auto mode, the software picture stabilisation kicks in as soon as the intensity of light drops below a certain level. It then captures a series of images to merge together and form a single image. If the subject moves while shooting, it discards certain frames that don’t fit in. overall it is a decent performer in low light but not as good as the best devices out there. The HDR mode on this device is pretty good as well. It is quick, thanks to the fast camera software and powerful hardware. The results that you obtain look very natural and you can’t tell that it is a layered picture. The macro shots are decent as well because it is able to focus easily on objects that are very close to it. Author Bio: The author has great interest in handset and technology reviews. Currently he is working with 91mobiles

Benefits of Hiring a Message Taking Service for Your Business


Small business owners often work very long hours to make sure that their venture has the best possible chance of success in the early days. However, no matter how hard you work and for how long, if you cannot afford to hire a full-time assistant when you first start up your own company, there will be times when potential customers are unable to speak to anybody and it is at such times that they may well decide to contact another supplier who has a representative free to take their call.
The importance of having a real person answering customers’ enquires whenever you are unable to do so cannot be overstated. Just think about how you feel when you call a retail outlet to ask about a product they sell and have to leave a message on a machine instead of talking to somebody and you will know why this eventuality should be avoided at all costs when you are trying to establish a<--more--> new business.

Possible solutions

If you cannot afford to hire a full-time receptionist or it does not make sound financial sense to do so, you will have to think of another solution that will ensure prospective customers can talk to a friendly, well-informed company representative whenever you are unable to come to the phone. Message taking services, sometimes bundled as part of a virtual office package and sometimes sold as a standalone solution, offer a cost effective way to handle the problem that does notinvolve making a long-term commitment. Flexibility is important when you first start out in business as it is very difficult to forecast future turnover with any degree of accuracy and therefore what level of services you may require in six months’ or a year’s time.

The main benefits

We have already touched upon two of the biggest benefits of hiring a firm to take messages on your behalf but to make it easier for you to evaluate your options, they are listed below with some notes on why they could be important to your business.

·         Making your clients feel important - machines may be efficient at recording messages that people leave but they do not make your clients feel special so they should be avoided unless absolutely necessary. Whether you use a service such as those outlined above or have your calls forwarded to a mobile phone when you are away from your desk, do not use an answering machine to field enquires on your behalf.
·         Presenting the right image – if prospective clients get the impression that your company is operating on a shoestring, they may be less inclined to give you their valuable custom. A professionally trained and experienced receptionist will ensure that callers have a positive impression of your organisation after they have put down the telephone.
·         Customised responses – unlike a machine, a receptionist that works for a message taking service can be given instructions on how to deal with different types of calls, thereby ensuring that any urgent business is attended to promptly.
