The iPhone and their gimmicky "depth control" At first, I wondered if they were really adjusting the lens. But now I see on tv that their gimmicky control is on a still image, already captured.

Bokeh
From Wikipedia, the free encyclopedia
In photography, bokeh is the aesthetic quality of the blur produced in the out-of-focus parts of an image produced by a lens. Bokeh has been defined as "the way the lens renders out-of-focus points of light". Differences in lens aberrations and aperture shape cause some lens designs to blur the image in a way that is pleasing to the eye, while others produce blurring that is unpleasant or distracting ("good" and "bad" bokeh, respectively). Bokeh occurs for parts of the scene that lie outside the depth of field. Photographers sometimes deliberately use a shallow focus technique to create images with prominent out-of-focus regions.
Bokeh is often most visible around small background highlights, such as specular reflections and light sources, which is why it is often associated with such areas. However, bokeh is not limited to highlights; blur occurs in all out-of-focus regions of the image.
Emulation
Bokeh can be simulated by convolving the image with a kernel that corresponds to the image of an out-of-focus point source taken with a real camera. Unlike conventional convolution, this convolution has a kernel that depends on the distance of each image point and – at least in principle – has to include image points that are occluded by objects in the foreground. Also, bokeh is not just any blur. To a first approximation, defocus blur is convolution by a uniform disk, a more computationally intensive operation than the "standard" Gaussian blur; the former produces sharp circles around highlights whereas the latter is a much softer effect. Diffraction may alter the effective shape of the blur. Some graphics editors have a filter to do this, usually called "Lens Blur."
An alternative mechanical mechanism has been proposed for generating bokeh in small aperture cameras such as compacts or cellphone cameras, called image destabilisation, in which both the lens and sensor are moved in order to maintain focus at one focal plane, while defocusing nearby ones. This effect currently generates blur in only one axis.
Some advanced digital cameras have bokeh features which take several images with different apertures and focuses and then manually compose them afterward to one image. More advanced systems of bokeh use a hardware system of 2 sensors, one sensor to take photo as usual while other ones record depth information. Bokeh effect and refocusing can then be applied to an image after the photo is taken.

Though difficult to quantify, some lenses have subjectively more pleasing out-of-focus areas. "Good" bokeh is especially important for macro lenses

Bokeh
From Wikipedia, the free encyclopedia
Origin
The term comes from the Japanese word boke, which means "blur" or "haze", or boke-aji, the "blur quality". The Japanese term boke is also used in the sense of a mental haze or senility.

Bokeh
From Wikipedia, the free encyclopedia
Origin
The related term bokashi means intentional blurring or gradation.
The English spelling bokeh was popularized in 1997 in Photo Techniques magazine, when Mike Johnston, the editor at the time, commissioned three papers on the topic for the May/June 1997 issue; he altered the spelling to suggest the correct pronunciation to English speakers, saying "it is properly pronounced with bo as in bone and ke as in Kenneth, with equal stress on either syllable". The spellings bokeh and boke have both been in use since at least 1996, when Merklinger had suggested "or Bokeh if you prefer." The term bokeh has appeared in photography books as early as 1998. It is sometimes pronounced (boke-uh).

Details about my recent sleep are very fuzzy today. Can't remember for sure when I woke up. 3 am maybe. Or maybe shortly after midnight, can't really remember as I usually can. Remember dreaming something about driving my Jeep. Then I returned to it where it was parked in a parking lot after I was traveling through some passageways, hallways in a transit facility maybe. The only part I remember clearly is where a woman, I assume was my imaginary girlfriend asked me out for drinks or something. I told her we needed to keep it really casual though because all I had to wear was sweatpants. Kind of the downside to dating a homeless person I reflect now as I write this. She told me she would wear something with holes in it. I hope that was her in my dream, although the woman in the dream seemed to be someone unfamilar though. But I have noticed that happening with other people I know. They are represented, somehow, by a different person, but I think of them as someone specific. I feel like that is part of the manipulation. I have noticed something similar in real dreams, but I don't think it is the same here. I think they are disquising themselves in my dream for some reason. Anyway, if it really was her, she actually doesn't have to worry about dressing down if we were to go out. Of course, if I have my way, it would be a moot point because why would I want to go out with her when I am in such an ugly situation? At the minimum, I would want to be back to work so that I have regained some independence. And hey, next time you are in my dreams, dear imaginary girlfriend, how about wearing a bikini? Red would be good, or yellow maybe. That would be sweet!

STS-82 Day 5 Highlights
Back to STS-82 Flight Day 04 Highlights:
On Saturday, February 15, 1997, 7:00 a.m. CST, STS-82 MCC Status Report # 9 reports:
Early this morning, astronauts Greg Harbaugh and Joe Tanner completed a 7 hour, 27 minute spacewalk in the cargo bay of the Shuttle Discovery to replace and install several new engineering components in the Hubble Space Telescope.
After being awakened late Friday afternoon, Harbaugh and Tanner completed the checkout of their spacesuits well ahead of schedul, allowing them to start the second spacewalk of the flight at 9:25 p.m. Central time, almost one hour ahead of schedule.
Harbaugh and Tanner went right to work, replacing a degraded Fine Guidance Sensor and a failed Engineering and Science Tape Recorder with new spares. Payload controllers verified that the new Fine Guidance Sensor and the new tape recorder were healthy and ready to support the telescope's scientific efforts. The astronauts also installed a new unit known as the Optical Control Electronics Enhancement Kit, which will further increase the capability of the new Fine Guidance Sensor.
During the spacewalk, the astronauts and flight controllers took note of cracking and wear incurred by thermal insulation which protects several areas of the telescope. The part of the telescope which is in the direction of travel and always exposed to the sun has experienced slight cracks and delamination during almost seven years of time on orbit. Flight controllers and Hubble project managers are evaluating whether some repair work might be performed to certain portions of the telescope's insulation during the final spacewalks of the flight.
As Harbaugh and Tanner neared the end of their work in the cargo bay, Discovery's small maneuvering jets were fired for about 20 minutes to gently raise Hubble's altitude by about 1.8 nautical miles. The reboost effort by Commander Ken Bowersox and Pilot Scott Horowitz will be performed again near the end of the final two spacewalks and should raise Hubble's altitude by a total of about five nautical miles. Harbaugh and Tanner returned to Discovery's airlock at 4:52 A.M., with more than 14 hours of spacewalk servicing time having been logged during the first two excursions in the Shuttle's cargo bay.
The astronauts will begin an eight-hour sleep period at 9:25 this morning and will be awakened at 5:25 this afternoon for the third spacewalk by Mark Lee and Steve Smith. They will replace an ailing Data Interface Unit, swap out another science and engineering tape recorder for a new solid state recorder and will replace a faulty Reaction Wheel Assembly for a new unit to help steer the telescope to its targets.
Discovery and the Hubble Space Telescope continue to orbit the Earth every 90 minutes at an altitude of approximately 370 statute miles with all of the Shuttle's systems still operating in excellent condition.
On Saturday, February 15, 1997, 5:00 p.m. CST, STS-82 MCC Status Report # 10 reports:
With two spacewalks complete, the STS-82 crew has met the minimum success criteria for the second Hubble Space Telescope servicing mission, but still has plenty of work left to do.
Tonight, astronauts Mark Lee and Steve Smith will leave the crew cabin for their second spacewalk of the flight. Lee and Smith are scheduled to install a new Data Interface Unit in HST and swap out a science and engineering tape recorder with a new solid state recorder. Unlike the older reel-to-reel recorder, the new digital recorder has no reels, no tape or moving parts to wear out and unlimited lifetime. Data is digitally stored in computer-like memory chips until HST's operators at the Goddard Space Flight Center play it back. Lee and Smith also will replace a Reaction Wheel Assembly that failed late last year with a new unit to help steer the telescope to its targets.
The Hubble Space Telescope was designed for on-orbit servicing with three maintenance scenarios in mind. They are incorporating technological advances into the science instruments as was done with the installation of the Space Telescope Imaging Spectrograph and the Near Infrared Camera and Multi-Object Spectrometer, replacing items such as the tape recorders and reaction wheels which normally degrade over time; and correcting random equipment failures or malfunctions.
If there is time during the spacewalk, Lee and Smith may perform some simple operations to assist engineers in planning for the possibility of performing some repairs to the aging thermal covering of the telescope. Controllers and astronauts have noticed areas on the telescope where the insulation is peeling. The tasks include bringing materials that could be used for the repair back into the crew cabin, assessing how brittle the insulation is and testing how well Kapton tape adheres to the insulation.
The spacewalk is officially scheduled to begin at 10:20 p.m., but for the first two EVAs, crew members completed their preparations early so that they were ready to begin between 9 and 9:30 p.m.
Also during the sixth day of the mission, Commander Ken Bowersox and Pilot Scott Horowitz will fire the small steering jets in the next phase of the effort to reboost the telescope. The first reboost burn raised Hubble's altitude by about 1.8 nautical miles, and a second unplanned burn, which was required to move Discovery a safe distance from some orbital debris, raised the orbit another half mile. Overall, flight controllers plan to raise HST's orbit about 7 statute miles.

Brave New Hard Drives
File that, would you? There was a time when your only choice was to stuff a piece of paper in a drawer somewhere (and hope that later, you'd remember where).
Today, we take digital storage for granted but the fact is, the possibilities for storing all sorts of files – words, numbers, images, music, video, and more – have been growing by leaps and bounds for the past fifty years, as computers themselves shrunk from forests of machines filling huge rooms to thin pieces of plastic apt to slide off the laps of careless users.
When PCs first came out, there were no affordable hard drives. Even when the IBM PC was introduced in 1981, it had only a 160 kilobyte floppy drive. The first mass market PC with a built-in hard drive was the IBM XT, which came out in 1983, with a whopping 10 megabytes of storage.
The original 160 KB floppy could store about 164,000 bytes or characters – enough for about 137 pages of double spaced text. Forget about graphics, music or video. That 10 megabyte drive back in 1983 could store about 8,800 pages of text.
The comparison to today's PCs, most of which are likely to have an at least 40 gigabyte hard drive, is dramatic. High end PCs tend to have 500 GB hard drives, which can store nearly 550 million double spaced pages or more than 128,000 songs or high resolution digital photos.
And Seagate makes a PC hard drive that stores 750 GB.
While it took until the 1980s for hard drives to migrate down to PCs, they were actually invented back in the 1950s. The first hard drive used in a commercial computer was unveiled by IBM 50 years ago this week on September 13, 1956.
That first drive assembly, called the "IBM 350 disc storage unit" was part of the IBM 305 RAMAC computer, according to Craig Butler, IBM's manager of disc storage products.
The device, according to Butler, made it possible for businesses to access data on a random basis without having to predefine the order of access - similar to the way you would locate a song on a cassette tape.
The storage process was called "continuous accounting" because it allowed users – that is, businesses who could afford it - to process data right after it was loaded into the computer.
The device, which stored five million characters (a bit short of 5 megabytes), cost $35,000 in 1956 dollars and stood 5 feet tall, a little less than 6 feet wide and 2.5 feet deep.
Storage capacity for drives is measured in areal density – the number of bits per square inch of storage surface. The areal density of today's drives, according to Butler, is 64 million times higher than it was back in 1956: an increase of 46 percent per year. Butler expects drive capacity to continue to grow rapidly for the next couple of years but eventually slow down.
Still, consumers can expect to see significant improvements in capacity over the next few years. A relatively new breakthrough is technology that increases areal density by aligning bits of data vertically or perpendicularly, instead of horizontally.
Prior to this innovation, bits were stored on flat sections of the platter. Storing them vertically is a little like erecting a high-rise building, enabling engineers to pack more per inch into the total amount of disc real estate.

Zefram COCHRANE: I haven't aged. The Companion sees to that.
SPOCK: Captain. These instruments, they date from the time indicated. From your ship, Mister Cochrane?
COCHRANE: I cannibalised it. The food, water, gardens, everything else I need the Companion gives me. Apparently, it creates it out of the native elements.
KIRK: You say you can communicate with it. Perhaps you can find out what we're doing here.
COCHRANE: I already know.
KIRK: You wouldn't mind telling us?
COCHRANE: You won't like it.

Tony, you promised me and I promised you we wouldn't do the kind of stuff you did with Truck.
Remember when we thought it was all funny, like a game?
And all the other kids thought we were freaks or witches.
I know, Tia.
We lost all our friends until we quit doing the spooky stuff.
You should have let Truck hit you.
Are you kidding?
He's much bigger than me!
Then you should have made it look like he won.
I suppose.
