Apple iPhone 5
Design
When we envisioned the new iPhone, we landed on a remarkably
thin and light design. But it’s nearly impossible to make a device so thin and
so light without sacrificing features or performance.
We could have taken the easy way out and designed something
more reasonable and less remarkable. But we didn’t. If the technology didn’t
exist, we invented it. If a component wasn’t small enough, we re-imagined it.
If convention was standing in the way, we left it behind. The result is iPhone
5: the thinnest, lightest, fastest iPhone ever.
iPhone 5 is just 7.6 millimetres thin. To make that happen,
Apple engineers had to think small, component by component. They created a
nano-SIM card, which is 44 per cent smaller than a micro-SIM. The intelligent,
reversible Lightning connector is 80 per cent smaller than the 30-pin
connector. The 8MP iSight camera has even more features — like panorama and
dynamic low-light mode — yet it’s 25 per cent smaller. And the new A6 chip is
up to 2x faster than the A5 chip but 22 per cent smaller. Even with so much
inside, iPhone 5 is 20 per cent lighter and 18 per cent thinner than iPhone 4S.
Thinnest Display
Making a thinner, lighter iPhone meant even the display had
to be thinner. Apple engineers accomplished that by creating the first Retina
display with integrated touch technology. Which means instead of a separate
layer of touch electrodes between display pixels, the pixels do double duty —
acting as touch-sensing electrodes while displaying the image at the same time.
With one less layer between you and what you see on iPhone 5, you experience
more clarity than ever before. All on a display that’s 30 per cent thinner than
before.
Finely Crafted
Never before has this degree of fit and finish been applied
to a phone. Take the glass inlays on the back of iPhone 5, for instance. During
manufacturing, each iPhone 5 aluminium housing is photographed by two
high-powered 29MP cameras. A machine then examines the images and compares them
against 725 unique inlays to find the most precise match for every single
iPhone.
Look at iPhone 5 and you can’t help but notice the exquisite
chamfer surrounding the display. A crystalline diamond cuts this bevelled edge.
It’s what gives iPhone 5 its distinctive lines. Fitting for a phone so
brilliant.
Precision-Matched Inlays
During the assembly process, each iPhone 5 aluminium housing
is photographed by two high-powered 29MP cameras. A machine then compares the
images with 725 uniquely cut inlays to find a precise match.
Sapphire Crystal
Although the surface of the iSight camera is as clear as
glass, it’s not made of glass. It’s actually sapphire crystal, whose hardness
is second only to diamond on the scale of transparent materials. That means the
surface of the lens is far less likely to scratch.
Diamond-Cut Bevelled Edge
A crystalline diamond is used to cut the chamfers of iPhone
5. This process gives the bevelled edge its beautiful sheen.
Earphone
It’s not easy to create earbud-style headphones that not
only feel good in your ears, but also sit securely in them. That’s because
everyone’s ears are different. Using optical scans combined with silicone
moulding, Apple designers created 3D models of various ear types to find a
common shape across many different people. That shape led to the unique look of
the new Apple EarPods. Unlike traditional circular earbuds, their design is
defined by the geometry of the ear. Which makes them more comfortable for more
people than any other earbud-style headphones.
They’re more stable and durable too. Apple engineers asked
more than 600 people to test over 100 iterations of the Apple EarPods. Testers
ran on treadmills in extreme heat and extreme cold. They performed various
cardio workouts. They were even asked to shake their heads from side to side,
and up and down. The result: Apple EarPods provide stronger protection from
sweat and water, and they’re remarkably stable in the ear. Which means they
stay in, even when you’re on the go.
4 Inch Retina Display
More display means more to see.
Anyone can make a larger smartphone display. But if you go
large for large’s sake, you end up with a phone that feels oversized, awkward
and hard to use. iPhone 5 features a 4-inch display designed the right way:
it’s bigger, but it’s the same width as iPhone 4S. So everything you’ve always
done with one hand — typing on the keyboard, for instance — you can still do
with one hand. On a larger canvas that lets you see more of every web page.
More of your inbox. More events on your calendar. Even more apps on your Home
screen.
It’s more vibrant too.
This isn’t just a larger display. It’s a larger Retina
display. At 326 pixels per inch, it has a pixel density so high, your eye can’t
distinguish individual pixels. And as stunning as the Retina display is on the
iPhone 4S, this one gives you 18 per cent more pixels for an impressive
1136x640 resolution. Colours get a boost too, with colour saturation that’s 44
per cent greater than before. So with iPhone 5, the games you play, the words
you read, the images you see and the apps you love look and feel incredibly
vivid and lifelike. For big-time entertainment, iPhone 5 lets you watch
widescreen HD video in all its glory — without letterboxing.Ultra Fast Wireless
Next-generation mobile data and wireless connectivity
iPhone 5 supports more networks all over the world. That
includes advanced networks such as HSPA, HSPA+ and DC-HSDPA. Browse, download
and stream content at ultra-fast speeds. Dual-band 802.11n wireless
connectivity accelerates your Wi-Fi experience too — up to 150 Mbps.2

Most Haunted Place in India- Bhangarh Fort
There is a belief about Bhangarh that the place is haunted and no one dares to go after sunset there.
Bhangarh is a place between Jaipur and Alwar in Rajasthan state of India. Bhangarh is known for its ruins, but still worth a visit; the place is beautiful and tranquil. What remains though, is a shadow of a once beautiful kingdom.
It’s still majestic. This medieval kingdom, that is. Or rather, the remains of it. Hundreds of years ago, its occupants fled. Or died. Nobody’s sure. Not a single human soul lives in the 158 hectares of land. Snakes slither along rocky corners. Climb up to the crumbling palace into the dark hallways, you’ll be greeted by the smell of dead bodies and gunpowder. Bat droppings apparently smell of war. You’ll see a secret passage guarded by orange and silver markings. And rats. Tantriks come here to perform black magic. Most temples inside have no idols. Welcome to the real city of djinns.
What does the signboard say?
The Government of India
The Archeological Survey of India, Bhangarh
Important warning:
1. Entering the borders of Bhangarh before sunrise and after sunset is strictly prohibited.
2. Shepherds and woodcutters who enter Bhangarh area will face legal action.
3. The Kewda or Pandanus trees found in Bhangarh area belong to the Archaelogy Survey of India. Is it forbidden to subject this tree to any kind of harm.
Note: Anyone flouting of the rules mentioned above will face legal action.
History
The story (and the history) of the Bhangarh began in the year of 1573 when the fortress was established. Built by Raja Bhagawant Das, the ruler of the city of Amber, Bhangarh Fort has become the residence of Madho Singh, ruler’s second son who fought alongside his father and brother in many wars. The decline of Bhangarh Fort started in 1630 after Chhatr Singh, son of Madho Singh got killed in a violent attack. The decline continued until 1783 when the fortress and the city were completely abandoned following that year’s famine.
Bhangarh Myths
It is said that the city of Bhangarh was cursed by
the Guru Balu Nath, causing the towns evacuation. Balu Nath sanctioned
the establishment of the town but said: “The moment the shadows of your
palaces touch me, the city shall be no more!” Ignorant of such
foreboding, one ambitious descendant raised the palace to such a height
that its shadowed Balu Nath’s forbidden retreat and thus the town was
devastated as prophesied. The small samadhi where Balu Nath is said to
lie buried is still there.
The other myth is as follows: The charm of princess of Bhangarh
Ratnavati was said to be matchless in all of Rajasthan. Being eighteen
years old, the princess started getting matrimonial offers from other
states. In the same region there lived a tantrik, a magician well versed
in the occult, named Singhia who was desperately in love with the
princess knowing that he would never be allowed to even see her, let
alone meet her. One day, he saw the princess’ maid in the market buying
scented oil for her. Seeing this, he got an idea by which he could meet
the princess. He used his black magic and put a spell on the oil which
would hypnotize the princess by her merely touching the oil, and she
would surrender herself. The princess foiled this plan though. She had
seen the tantrik enchanting the oil, and she therefore threw it away,
whereupon the flagon rolled over a stone. As soon as the oil touched the
stone, it started rolling towards the wicked tantrik and crushed him.
While dying, Singhia cursed the palace with the death of all who dwelt
in it, without any rebirth in their destinies. The very next year there
was a battle between Bhangarh and Ajabgarh and Ratnavati died.Tales of the yore
According to the Rajasthan Tourism website, “the evil effects of the (tantrik’s) curse are believed to be working even now.” The Internet is flooded with horror tales. People claim to have heard the tinkling of payals, seen the ruined market come to life. Tarun Akash, a student, wrote on indianfusion.aglasem.com about how he along with two friends met with an accident after a night spent in Bhangarh. The odd thing, he says, was that they were the only people to have been hurt in a bus of more than 50 people, even though they were sitting 5-6 rows apart. Bhangarh is on several lists of ‘the most haunted places in the world’ on the Web. Bhoot, chudail, djinns – she’s witnessed them all over the last three decades, says a wizened Rama Devi, who has been running a water stall outside the monument premises ever since she got married. “They are all there. But we are not scared. We have our temples,” she says.
Another indicator of ghosts was a signboard put by the Archaeological Survey of India (ASI) outside the ruins that warned people against entering the fort after sunset. The notice has now been removed because everybody who visited saw this as proof of ASI’s belief in the paranormal. “These rumours are rubbish,” says Vasant Kumar Swarnakar, superintending archaeologist, Jaipur circle, ASI. “Every monument in the country has the same sign. It has nothing to do with ghosts or spirits,” he insists. “All that is rubbish,” he repeats. It’s the wild animals that make the area dangerous. Its proximity to Sariska makes it a haunt for foxes, panthers and even tigers at night.
Besides, adds Swarnakar, “Our guards patrol the area at night but no incident has ever occurred!” But several people have come screaming out “ghost”. There have been deaths. “It’s because people try to enter the ruins from the hills at night, the boulders are loose, people fall!” he says.

Digitial Camera- Tips before buying Digital camera
Megapixels
- Remember it takes 4 times as many megapixels to make an 8x12 print as sharp as a 4x6 print.
- You need 12.8 megapixels to get double the resolution of 3.2 megapixels.
- You might not be able to see much difference in a print made from 3.2, 4, or 5 megapixels.
- You can make a surprisingly large print from a 3.2 megapixel image.
- Experiment for yourself by displaying part of a picture on your computer monitor and calculating how large a print it would make at that magnification.
Digital Sharpening
- Most digital cameras will "digitally sharpen" pictures before saving them.
- A little bit of sharpening is usually a good thing but it introduces visible artifacts so some cameras let you control how much or little sharpening is done.
- You can always sharpen later with software on your computer--you can't as easily unsharpen to remove the artifacts.
- There is considerable variation between cameras in the amount of sharpening done by default.
Battery usage
- Digital cameras use A LOT of battery power (much more than film cameras)! This seems to be largely due to the amount of computation required to capture and save the image after you take a picture and to continually update the display before taking a picture.
- Although they all use a lot, some models use much more than others. Be sure to check how long a charge (or set of batteries) will last.
- Can you save power by turning off the display? If so, is the camera sill usable?
- Will it still briefly display the picture after you take it?
- Do all the shooting modes still work with the display off?
- Does it slow down camera operation to have the display off?
- Can you change camera settings with the display off?
- Does the camera use standard AA batteries?
- If so, can you use standard (cheap-to-replace) NiMH rechargeable batteries?
- In a pinch, can you also use alkaline or single-use lithium batteries?
- The fastest AA NiMH battery chargers take only 10-15 minutes and charging batteries outside the camera means you can still use it while charging if you have another set of batteries.
- Does the camera correctly detect the kind of AA battery in use and adjust the low-voltage threshold accordingly? (For example, the Nikon 3100 has a low-voltage threshold set for single-use lithium batteries. If you use NiMH batteries, after just a few shots are taken, it says the batteries are low and soon after refuses to use them).
Viewfinder type, accuracy, usability.
- How accurate is the viewfinder?
- What information about camera settings is visible in the viewfinder (if any)?
- If camera settings can only be seen/changed on the screen, consider how useful the viewfinder will be if you can't see the screen without your glasses or in bright sunlight.
- Some viewfinders are optical (like on film point and shoot cameras) and some are miniature screens behind an eye-piece (like video cameras).
- Optical is clearer but usually less accurate.
- Video is typically low-resolution, slow to update but more likely to show camera settings and be usable in bright light.
Playback Magnification
- After you've taken a picture, can you zoom in on the display enough to check if the focus is good or if there is purple fringing? (About 10x playback magnification is needed for that).
- Assuming you can magnify 10x or more, is it reasonably fast to do so?
Some cameras let you zoom and crop a photo you've already
taken into a new photo (in the camera). This may be useful if you're going to
print directly from your memory card but it may be more useful as a way of
gaining more playback magnification (if the camera doesn't have enough to tell
if a picture is really in focus).
Which camera settings persist after you turn off the camera?
- Are the choices sensible? (If you always want to take pictures at the highest quality, can you set that once or must you reset it each time you turn on the camera?)
- Will the settings persist if you take the batteries out to charge them? If not all settings, at least the time and date?
- Some cameras have a separate watch battery for keeping settings while the main batteries are out.
Is there a panorama mode?
- This lets you take several pictures which overlap and later "stitch" them into one (more or less) seamless picture on your computer. (Seamlessness takes care and effort).
- Does the panorama mode help you compose your panorama by showing you a piece of the previous picture on the screen so you can line-up the next component picture?
- Does the camera come with "panorama stitching" software which will run on your computer?
- Does the software refuse to stitch pictures not taken in panorama mode (such as in manual or some other scene mode)? Some Olympus software has this limitation.
Is there EXIF header display?
- In playback mode, can the camera display all the modes and settings in effect when the picture was taken? Usually they're all recorded in the "EXIF" header in a JPEG file but not all cameras let you see the values on the screen.
Effective ISO
- Many cameras can automatically increase the effective "film speed" when subject is slightly beyond the range of built-in flash.
- Do you get any control over this for other situations?
- How much ISO boost is available? (Canon A70 goes from ISO 50 to 400)
- How much ISO boost can be used before noise becomes unacceptable?
- Some cameras have much less noise than others at boosted ISO.
Is there a "best
shot selector" mode?
Some Nikons have this and it is fantastic. It lets you press
and hold the shutter release and take 10 pictures in rapid succession and the
camera will automatically choose and keep only the sharpest. If you're not
using a tripod or flash and you need to use a slow shutter speed, this is much
faster than taking a picture, reviewing it, deleting it, trying again and again
until you get lucky and one is sharp enough.
Some cameras let you attach voice memos to your pictures.
This may be handy, though I haven't used it (because it is too awkward to do on
my camera).
Can one set the camera to take a series of pictures as long
as the shutter release is pressed? If so, how fast can it take them? (Usually
depends on size and compression settings).
Can the camera take any pictures using just its built-in
memory? Can the built-in memory be used to transfer pictures from one memory
card to another?
What USB protocols does the camera support?
- USB 2.0 allows much faster data transfer than USB 1.1 (but either will work).
- "Picture Transfer Protocol" (PTP) is supported on Windows XP and Macintosh OSX but not so well on older OS versions or Linux/Unix.
- With the right software, some cameras can be operated (remotely) from a computer using PTP.
- "USB mass storage" (which makes the camera look like a disk drive) works for all computers with USB and is also what you get if you take the memory card out of the camera and put it in a card reader.
- Using a card reader also means you won't need to run down your batteries while transferring pictures from (or to) your memory card.
- (Card readers cost as little as $10.)
Video output
Some cameras have video output so you can view your pictures
on a TV (at low resolution). If the camera has this feature, it may also have a
"slide show" setting where it will automatically cycle through the
pictures. (This can be nice at Grandma's house if she doesn't have a computer.)
Some digital still cameras can take short low-resolution
video clips. If this is of interest...
- Is there sound too?
- Can you edit them in-camera?
- What is the resolution, frame rate and maximum recording length?
Type, size and speed of memory card
- Whatever format you use, it may be wise to get two half-sized cards rather than one giant card so you have a better chance of not losing all your pictures at once if your card gets damaged or corrupted.
- Flash memories have a maximum read and write speed usually given as 4x or 12x. Faster is better until the camera (or card reader) becomes the limiting factor. (I think x=150kB/s like CD speeds).
- Some people think the older/larger "compact flash" is more robust and less likely to get damaged than some of the smaller formats (especially "smart media").
- Occasionally airport X-rays can corrupt data on your memory card. A card format which you can carry through the metal detector (avoiding the X-rays) may be worth some consideration.
