Portrait Photography

Although you may think so, portrait photography isn’t all that easy. There are several factors you need to keep in mind in order to make your images worthwhile. Here are some sure fire ways of jazzing up your portrait photos!

Go propecia 90 tablets for Simplicity

Portrait photography demands you to stick to the subject at hand and not add anything else, either in the foreground or background. It has to be the subject in an environment where he or she feels comfortable. You also need to try to take pictures in natural light. If you're indoors, don’t use too many artificial sources of light. Sometimes one or two sources are good enough for some great portrait photos.

Be Ready Beforehand

It’s important to study the scene before the subject arrives. That could be adjusting the lighting and camera mode or even taking some test shots to see if the output is what you have in mind. Avoid under and over exposure by taking as many shots as you can so that when the subject comes in, you're not fiddling with your controls and wasting time.

Light Up the Background

When shooting outdoors, it’s great to have some backlighting. It could be a natural setting like sun rays streaming through the trees in the background or it could be artificial. Whatever the case may be, great backlighting adds depth and vivid colors to your portrait photos.

Don’t Shoot at Eye Level

Though it’s a common practice to shoot people at eye level, experts have another secret tucked away. It’s even better if you shoot portraits slightly below eye level. Not only will your subject look more real, but the picture will also seem much more flattering. That's particularly true when you're taking pictures up close. Whether the subject is standing or sitting, you can use this technique for maximum effect.

Follow the Eye

If your subject is looking in one direction, it’s best to take their side profile in such a manner where you leave empty space in the direction they're facing. As a rule, if the person you're photographing is looking in one direction, it's best to place them on the opposite side of the frame. If the subject is looking in one direction and you photograph them without leaving any space on either side, the picture will look somewhat incomplete. But when you leave space where the subject is looking, it seems more natural.

Unusual Angles

Nothing beats experimentation! Some people look particularly good in some angles and not so good in others. So, it’s best to shoot at different angles to see which angle suits your subject the best. That means, you could try shooting low, very low or you could take the picture from high above the ground. Just know that you have options!

Face the Camera

Portrait photos fall into two categories: formal and informal. When taking formal portraits, it’s important to make the subject lean into the camera for a greater effect. Not only will that make it a more personal shot, but the subject will appear more friendly and interactive. You could also get your subject to lean back, but that has to be handled with care. Your picture should make it look like the subject is leaning back to laugh or that they're feeling very self-satisfied. In no way should they look aloof, unattached or disinterested.

That’s all, folks! Now, go out and take some fantastic portrait photos. Have fun!

drivers

Q:
I just recently updated the driver for my scanner and ever since, it seems like my computer is running out of sync. Everything seems very unstable and just not like it used to be. Is there any way I can reverse this or do something else about it? Please help!

A:
The answer to your problem is actually much more simple than you probably think. It sounds like you just need to do a little driver rollback. What's that, you ask? Well, let me explain!

Whenever you update a driver (basically, replace an old driver) on your computer, whether it's for a scanner, a digital camera, a video card or any other device you may have installed on your PC, it's not always guaranteed that the update will come through smoothly. Often times, it's invalid, incorrect or even corrupted. If that happens, it can really affect how your computer performs. It could even go as far as render your computer unbootable or make the device completely fail whenever you try to use it.

Luckily, in Windows XP, you can sort of reverse the update with the driver rollback feature. With that, XP actually saves a copy of the previous driver for you, so if you have any trouble with the new one, you can go back to using the old one. That will get you back to a place where you didn't have as many headaches when trying to use a certain device and it will also give you some more time to try and figure out why the new driver failed in the first place. Cool, huh?!

So, if your computer seems to be acting unstable, give the rollback a spin. Now, the driver rollback feature in Windows XP only allows for one level of a rollback, which basically means that only one prior driver version can be saved at one time. Also, I want you to know that the driver rollback option works for any class of device, but it will not work for printers, so you'll definitely want to keep that in mind. Okay, here's how you do it!

1.) Make sure you're logged in to your computer under the Administrator account.

2.) Find the My Computer icon on your desktop, right click it and choose Properties.

3.) Next, click on the Hardware tab and then the Device Manager button.

4.) Once you're in the Device Manager box, scroll down to the driver you want to roll back.

5.) Right click on the driver's name and choose Properties.

6.) Now, click on the Driver tab and then click on the Roll Back Driver button.

That will finish out the process for you and you will be back to using your old driver. Now, if you wish, you can do some investigating as to why the new driver didn't work for you. If you somehow figure it out, try the update again. propecia 90 day supply At least you now know you have the rollback option to fall back on. And what a great feeling that is!

Head ’em Out and Back it up with External Hard Drives

Tech Tips 176

Head 'em  Out and Back it up with
External Hard Drives

By Bryan Lambert – Sunday, July 13, 2008

Pull Quote 176In the olden days when hard drives were counted in megabytes and the floppy disk was king, backing up a hard drive and transferring files between desktop computers bordered on insanity. Those days of ancient computer history are long gone. These days, when we want to back up a computer, maybe archive some important files, or simply want to transfer data from one computer to another, we have the external hard drive.

Since an external hard drive lives outside the computer, it is ideal for backing up and making more room on your hard drive especially when personal files such as photos, documents, music, and videos can take up a massive amount of space in only a few years. Another advantage of an external drive is that it can even be taken off site for safe keeping.

 

Port_HDThe Basics

An external drive, when it comes down to it, is simply a hard drive (yes, the same kind that is in your computer) packed inside an external case. The basic types are: mobile, desktop and network.  Mobile drives are small (they usually contain a hard drive that is found in a laptop), sleek and can usually run just off the computer's power, however they also tend to cost more and have smaller capacities than desktop drives. 

Internal HDDesktop drives usually contain a hard drive the same as those found in a desktop computer.  Because of this, these drives will deliver a lot of bang for the buck.  Though larger than mobile drives, they cost less per gigabyte and have a much larger capacity propecia 5mg online (even into the terabyte range when multiple drives are placed inside an external case).  However, because of their larger physical size and their need for a wall socket to draw power, they tend to be placed somewhere on a computer desk – and stay there. 

FujiNetdriveAnother type of drive is the NAS, or Networked Attached Storage external drive. Because of their specialization and usually very large size, they tend to have a higher cost than either a typical mobile or desktop drive. These will usually be near a router or similar network component and also will be more difficult to set up.

Just as the drive types can vary, the actual design of the external drive can vary.  Some may be fortified to withstand travel; some may be designed by famous design groups such as the Lacie line of drives designed by Porsche; and some may have extra features ext_HDsuch as a one-touch backup button or a variety of video and audio ports that let the hard drive be used as a media center.

External drives are typically prebuilt with the drive already in the case and formatted for ease of use.  Some users can also make their own external drives by purchasing an empty external drive case and hard drive separately and “building it themselves.” Purchasing an external drive case may be an excellent idea if you already have an extra hard drive laying around.

 

Drive Interfaces

USB2.0Another aspect of an external hard drive that can vary is the interface.  By far, the most popular interface is USB 2.0.  USB ports are found on just about every computer made. USB 2.0 is rated at 480 mbps (megabits per second), but because of its design, actual transfer speeds are lower than the theoretical speeds. However, USB 2.0 is still plenty fast enough for many users who are simply using the drive for external storage and backup.

FirewirelogoFireWire is another interface and actually comes in two varieties:  the original FireWire (also called iLink or IEEE-1394A) and its successor, FireWire 800 (also called IEEE-1394B).  The original FireWire is rated at 400 Mbps and FireWire 800 is rated at 800 Mbps.  Again, these are theoretical speeds, however because FireWire is designed differently than USB, both will deliver, on average, better throughput than USB 2.0 (especially FireWire800). FireWire is an ideal solution for those looking for faster performance from an external drive.

A relative newcomer is eSATA (external SATA) with a theoretical rating of 3000 Mbps.  Its design is such that, even in the real world, it will deliver constantly better performance than either FireWire or eSATAUSB. eSATA is not widely implemented, and add-on cards will typically need to be used.

An RJ45 Ethernet interface is used on drives that are designed to be attached to a network and be used as a shared drive.  Low cost NAS units can be found for home networks and Gigabit units are designed to run up to 1000 Mbps (but are backwards compatible with slower networks). 

With so many interfaces to choose from, many drive makers actually make multiple interface drives that will have two or more of the interfaces on them (though at a nominally higher cost then single interface drives).

Whether for backup or file transfer, adding an external hard drive to your computer is an idea that just makes sense!

Rights like free speech don’t always extend online

By ANICK JESDANUN | AP Internet Writer

10:38 AM EDT, July 7, 2008

NEW YORK

Rant all you want in a public park. A police officer generally won't eject you for your remarks alone, however unpopular or provocative.

Say it on the Internet, and you'll find that free speech and other constitutional rights are anything but guaranteed.

Companies in charge of seemingly public spaces online wipe out content that's controversial but otherwise legal. Service providers write their own rules for users worldwide and set foreign policy when they cooperate with regimes like China. They serve as prosecutor, judge and jury in handling disputes behind closed doors.

The governmental role that companies play online is taking on greater importance as their services — from online hangouts to virtual repositories of photos and video — become more central to public discourse around the world. It's a fallout of the Internet's market-driven growth, but possible remedies, including government regulation, can be worse than the symptoms.

Dutch photographer Maarten Dors met the limits of free speech at Yahoo Inc.'s photo-sharing service, Flickr, when he posted an image of an early-adolescent boy with disheveled hair and a ragged T-shirt, staring blankly with a lit cigarette in his mouth.

Without prior notice, Yahoo deleted the photo on grounds it violated an unwritten ban on depicting children smoking. Dors eventually convinced a Yahoo manager that — far from promoting smoking — the photo had value as a statement on poverty and street life in Romania. Yet another employee deleted it again a few months later.

"I never thought of it as a photo of a smoking kid," Dors said. "It was just of a kid in Romania and how his life is. You can never make a serious documentary if you always have to think about what Flickr will delete."

There may be legitimate reasons to take action, such as to stop spam, security threats, copyright infringement and child pornography, but many cases aren't clear-cut, and balancing competing needs can get thorny.

"We often get caught in the middle between a rock and a hard place," said Christine Jones, general counsel with service provider GoDaddy.com Inc. "We're obviously sensitive to the freedoms we have, particularly in this country, to speak our mind, (yet) we want to be good corporate citizens and make the Internet a better and safer place."

In Dors' case, the law is fully with Yahoo. Its terms of service, similar to those of other service providers, gives Yahoo "sole discretion to pre-screen, refuse or remove any content." Service providers aren't required to police content, but they aren't prohibited from doing so.

While mindful of free speech and other rights, Yahoo and other companies say they must craft and enforce guidelines that go beyond legal requirements to protect their brands and foster safe, enjoyable communities — ones where minors may be roaming.

Guidelines help "engender a positive community experience," one to which users will want to return, said Anne Toth, Yahoo's vice president for policy.

Dors ultimately got his photo restored a second time, and Yahoo has apologized, acknowledging its community managers went too far.

Heather Champ, community director for Flickr, said the company crafts policies based on feedback from users and trains employees to weigh disputes fairly and consistently, though mistakes can happen.

"We're humans," she said. "We're pretty transparent when we make mistakes. We have a record of being good about stepping up and fessing up."

But that underscores another consequence of having online commons controlled by private corporations. Rules aren't always clear, enforcement is inconsistent, and users can find content removed or accounts terminated without a hearing. Appeals are solely at the service provider's discretion.

Users get caught in the crossfire as hundreds of individual service representatives apply their own interpretations of corporate policies, sometimes imposing personal agendas or misreading guidelines.

To wit: Verizon Wireless barred an abortion-rights group from obtaining a "short code" for conducting text-messaging campaigns, while LiveJournal suspended legitimate blogs on fiction and crime victims in a crackdown on pedophilia. Two lines criticizing President Bush disappeared from AT&T Inc.'s webcast of a Pearl Jam concert. All three decisions were reversed only after senior executives intervened amid complaints.

Inconsistencies and mysteries behind decisions lead to perceptions that content is being stricken merely for being unpopular.

"As we move more of our communications into social networks, how are we limiting ourselves if we can't see alternative points of view, if we can't see the things that offend us?" asked Fred Stutzman, a University of North Carolina researcher who tracks online communities.

First Amendment protections generally do not extend to private property in the physical world, allowing a shopping mall to legally kick out a customer wearing a T-shirt with a picture of a smoking child.

With online services becoming greater conduits than shopping malls for public communications, however, some advocacy groups believe the federal government needs to guarantee open access to speech. That, of course, could also invite meddling by the government, the way broadcasters now face indecency and other restrictions that are criticized as vague.

Others believe companies shouldn't police content at all, and if they do, they should at least make clearer the rules and the mechanisms for appeal.

"Vagueness does not inspire the confidence of people and leaves room for gaming the system by outside groups," said Lauren Weinstein, a veteran computer scientist and Internet activist. "When the rules are clear and the grievance procedures are clear, then people know what they are working with and they at least have a starting point in urging changes in those rules."

But Marjorie Heins, director of the Free Expression Policy Project, questions whether the private sector is equipped to handle such matters at all. She said written rules mean little when service representatives applying them "tend to be tone-deaf. They don't see context."

At least when a court order or other governmental action is involved, "there's more of a guarantee of due process protections," said Robin Gross, executive director of the civil-liberties group IP Justice. With a private company, users' rights are limited to the service provider's contractual terms of services.

Jonathan Zittrain, a Harvard professor who recently published a book on threats to the Internet's openness, said parties unhappy with sensitive materials online are increasingly aware they can simply pressure service providers and other intermediaries.

"Going after individuals can be difficult. They can be hard to find. They can be hard to sue," Zittrain said. "Intermediaries still have a calculus where if a particular Web site is causing a lot of trouble … it may not be worth it to them."

Unable to stop purveyors of child pornography directly, New York Attorney General Andrew Cuomo recently persuaded three major access providers to disable online newsgroups that distribute such images. But rather than cut off those specific newsgroups, all three decided to reduce administrative hassles by also disabling thousands of legitimate groups devoted to TV shows, the New York Mets and other topics.

Gordon Lyon, who runs a site that archives e-mail postings on security, found his domain name suddenly deactivated because one entry contained MySpace passwords obtained by hackers.

He said MySpace went directly to domain provider GoDaddy, which effectively shut down his entire site, rather than contact him to remove the one posting or replace passwords with asterisks. GoDaddy justified such drastic measures, saying that waiting to reach Lyon would have unnecessarily exposed MySpace passwords, including those to profiles of children.

Meanwhile, in response to complaints it would not specify, Network Solutions LLC decided to suspend a Web hosting account that Dutch filmmaker Geert Wilders was using to promote a movie that criticizes the Quran — before the movie was even posted and without the company finding any actual violation of its rules.

Service providers say unhappy customers can always go elsewhere, but choice is often limited.

Many leading services, particularly online hangouts like Facebook and News Corp.'s MySpace or media-sharing sites such as Flickr and Google Inc.'s YouTube, have acquired a cachet that cannot be replicated. To evict a user from an online community would be like banishing that person to the outskirts of town.

Other sites "don't have the critical mass. No one would see it," said Scott Kerr, a member of the gay punk band Kids on TV, which found its profile mysteriously deleted from MySpace last year. "People know that MySpace is the biggest site that contains music."

MySpace denies engaging in any censorship and says profiles removed are generally in response to complaints of spam and other abuses. GoDaddy also defends its commitment to speech, saying account suspensions are a last resort.

Few service providers actively review content before it gets posted and usually take action only in response to complaints.

In that sense, Flickr, YouTube and other sites consider their reviews "checks and balances" against any community mob directed at unpopular speech — YouTube has pointedly refused to delete many video clips tied to Muslim extremists, for instance, because they didn't specifically contain violence or hate speech.

Still, should these sites even make such rules? And how can they ensure the guidelines are consistently enforced?

YouTube has policies against showing people "getting hurt, attacked or humiliated," banning even clips OK for TV news shows, but how is YouTube to know whether a video clip shows real violence or actors portraying it? Either way, showing the video is legal and may provoke useful discussions on brutality.

"Balancing these interests raises very tough issues," YouTube acknowledged in a statement.

Unwilling to play the role of arbiter, the group-messaging service Twitter has resisted pressure to tighten its rules.

"What counts as name-calling? What counts as making fun of someone in a way that's good-natured?" said Jason Goldman, Twitter's director of program management. "There are sites that do employ teams of people that

do that investigation … but we feel that's a job we wouldn't do well."

Other sites are trying to be more transparent in their decisions.

Online auctioneer eBay Inc., for instance, has elaborated on its policies over the years, to the extent that sellers can drill down to where they can ship hatching eggs (U.S. addresses only) and what items related to natural disasters are permissible (they must have "substantial social, artistic or political value"). Hypothetical examples accompany each policy.

LiveJournal has recently eased restrictions on blogging. The new harassment clause, for instance, expressly lets members state negative feelings or opinions about another, and parodies of public figures are now permitted despite a ban on impersonation. Restrictions on nudity specifically exempt non-sexualized art and breast feeding.

propecia 1mg 5mg /> The site took the unusual step of soliciting community feedback and setting up an advisory board with prominent Internet scholars such as Danah Boyd and Lawrence Lessig and two user representatives elected in May.

The effort comes just a year after a crackdown on pedophilia backfired. LiveJournal suspended hundreds of blogs that dealt with child abuse and sexual violence, only to find many were actually fictional works or discussions meant to protect children. The company's chief executive issued a public apology.

Community backlash can restrain service providers, but as Internet companies continue to consolidate and Internet users spend more time using vendor-controlled platforms such as mobile devices or social-networking sites, the community's power to demand free speech and other rights diminishes.

Weinstein, the veteran computer scientist, said that as people congregate at fewer places, "if you're knocked off one of those, in a lot of ways you don't exist."

Virgin warns 800 punters for file-sharing

'Important. If you don't read this, your broadband could be disconnected'

By John Oates

Published Thursday 3rd July 2008

The BPI has written to 800 Virgin Media customers warning them to stop sharing music files or risk losing their broadband connection.

The letters came in an envelope marked: "Important. If you don't read this, your broadband could be disconnected." But Virgin told Radio 1's Newsbeat that the phrase was a mistake and the letters were part of an education campaign. Virgin said it was not making any kind of accusation and that it was possible someone other than the account holder was involved.

When the Virgin campaign was revealed last month the company assured us that the letters were not part of a "three strikes" process. The BPI has pushed ISPs to warn users three times for copyright infringement before cutting off their broadband.

The individuals were identified by the BPI which, as we exclusively revealed , is working on a similar scheme with BT. The BPI letter sent on by BT warns of further action including "litigation and suspension by BT your internet connection".

At least one Virgin customer who received a letter in June told Newsbeat he was certain it was not him or his flatmates who were responsible for downloading the Amy Winehouse song. He said it was possible that someone had used the flat's wireless network.

Will McGree said: "The campaign is doomed to fail. Virgin will lose a lot of customers over this because people don't like to be accused of stealing music over their morning coffee.

"It made me feel betrayed. I was under the impression that I paid a broadband company to keep my internet propecia 10 years connection protected."

The BPI has been busy lobbying the government for stronger laws against file sharing. But the government seems to be resisting the pressure and is instead pushing the music industry and ISPs to get talking to find a licensed, and paid for, form of file sharing.

Although BT and Virgin are supporting the BPI's approach others, notably Carphone Warehouse, are refusing to co-operate.

A survey last month found 63 per cent of internet users were downloading unlicensed music.
