As part of our ongoing efforts to showcase some of the fun effects you can apply with photoshop, we're going to touch on how to selectively desaturate an image. There are multiple ways to achieve this type of effect; each method involving the utilization of Photoshops massive tool box to do the work for you. We’re going to go over a couple of different ways to selectively desaturate, but first, what does that even mean?
‘Saturation’ is a term used to describe the intensity of basic colors that make up an image. As such, the lower the saturation of the image, the less intense the colors. When an image has no saturation at all (see: desaturated) , it becomes a black and white image. ‘Selective saturation’ usually involves converting an image into black and white, with the exception of a single part of a photo that remains in color. Often, the part of the photo left in color is the primary subject.
Thousands of photographers have used this technique, with varying degrees of success, for a long time. We won’t claim that our example here is going to be high art, but it should serve as a nice guide.
With all due respect to Alexander Graham Bell, he couldn't possibly have known that his patent for "the method of, and apparatus for, transmitting vocal or other sounds telegraphically" would one day give birth to the modern day smartphone. He couldn't have foreseen the wonders that we take for granted today, like text messaging and voice-to-text searches.
We now live in a connected world, and today's smartphones define what it means to be a power user. Want to look up turn-by-turn driving directions on your phone? There's an app for that. There's an app for just about everything, even if they're sometimes tough to find (we're looking at you, Android Marketplace).
But for as much as we rely on our iPhone, Nexus One, or BlackBerry, it wasn't that long ago when you wouldn't think of trying to cram a mobile phone in your pocket. Remember when pagers were all the craze? Like computers, communication devices continue to evolve at a rapid pace, becoming faster, more portable, and increasingly flexible in functionality. It's been a wild ride getting to where we are today, and to pay homage to that journey, we take a look back at 40 of the most important phone models of all time.
In the pantheon of nerd achievement, water cooling ranks near the top—somewhere between installing Linux and becoming fluent in Klingon. And there’s a reason the hardest of the hardcore prefer water cooling: It’s incredibly effective at lowering the temperatures of core system components. With higher thermal conductivity and specific heat capacity than air coolers, water cooling can mean double-digit drops in CPU and GPU temperatures.
However, water cooling isn’t exactly a walk in the park. You’ve got two challenges ahead of yourself: Designing the water-cooling system that’s right for your PC, and actually putting it together. Both tasks will take some time and effort, but neither has to be daunting. Every first-time water-cooling build is a learn-as-you go experience, but we’ll walk you through the details and help you avoid the mistakes that would take the biggest toll on your system and your wallet.
Adobe's Photoshop is industry-standard software, used by creative professionals all over the world. It's a serious tool, with serious uses. But don't let all that fool you—it's also a ton of fun. That's why we're starting a new series of how-tos, where we'll show you how even photoshop-beginners can use the program to achieve lots of cool and fun effects. To kick it off, we'll show you how to do this:
Yep, you can clone yourself, using just a DSLR camera, a tripod, and Adobe Photoshop. The steps involved in this tutorial will act as a crash course in manual DSLR shooting, the use of a stable tripod, and the fundamental applications of ‘layers’ in Photoshop. As with any other creative hobby, learning these basic ideas will serve you well as you journey further down the complex path of photo editing and illustration.
Whether you are preparing to reuse a hard disk for another operating system, clear off your junk shelves by passing along outdated drives to a friend or relative, donate an old PC to a charity or school, discard a too-small USB drive or flash memory card, or repurpose an SSD, you don’t want to leave any information on the storage device. With stories abounding of identity theft aided by information lifted from discarded storage devices, you want devices you no longer plan to use to have no usable information when they head out the door.
When you erase/delete a file from your computer, it’s not really gone until the areas of the disk it used are overwritten by new information. If you use the normal Windows delete function, the “deleted” file is sent to the Recycle Bin until the space it uses is required by other files. If you use Shift-Delete to bypass the Recycle Bin, the space occupied by the file is marked as available for other files. However, the file could be recovered days or even weeks later with third-party data recovery software. As long as the operating system does not reuse the space occupied by a file with another file, the “deleted” file can be recovered.
In this article, we'll show you how to erase your drives the right way, leaving no trace behind.
Google Maps is great—it’s got tons of convenient, frequently updated information about pretty much everywhere in the world. There’s just one problem: It’s stuck on the internet. Or at least it was, because now, with Google Map Buddy, you can print Google Maps out at any size, whether you want to put together your own old-fashioned roadmap or make a giant geographical mural for you wall.
In addition, you can use Google Map Buddy to create large, continuous digital images from Google Maps, which make excellent desktop wallpapers. We'll show you how to do both in our Google Map Buddy how-to.
Unless you’ve been living under a rock for the last year, you know that 3D is this year’s entertainment buzzword. With 3D blockbusters like Avatar scoring megabucks in the theaters, 3D cinema’s jump to the living room is all but a foregone conclusion. But where does that leave all your old 2D files and DVDs?
Thanks to a couple of very cool programs and some clever scripting, there’s hope for them yet. In this article, we’re going to show you how to use AviSynth and VirtualDub, along with a script from the 3D Vision Blog to give any 2D film the 3D treatment.
Trying to fix a badly infected PC without HijackThis is sort of like going into surgery without a scalpel; it’s the only tool for the job when all other measures fail. New spyware strains and increasingly complex viruses emerge every day, and your PC’s immune system (i.e, antivirus software) isn’t always able to keep up. And if you’re performing emergency surgery on someone else’s PC, you may find that they didn’t have any AV software installed to begin with.
No matter how bad the infection, HijackThis gives you the means to dig deep into Windows to root out whatever it is that’s wreaking havoc. It’s not a cure-all, however, or even a cure-little. In fact, HijackThis doesn’t cure anything on its own. What HijackThis does do is give you a snapshot of the system’s registry and file settings, putting particular emphasis on the browser. It doesn’t discern between safe and malicious settings, so it’s possible to unintentionally inflict real harm if you don’t know what you’re doing. Follow along as we show you how to properly wield HijackThis.
Show of hands - how many of you are still clinging to Firefox not because it's the perfect browser, but because it's the best alternative out there to Internet Explorer? Probably a good many of you, and the reason why Firefox has been so hard to supplant as the No. 2 gateway to the Web is because Mozilla had the foresight to make it extensible. Thousands of add-ons exist allowing users to custom tailor the open-source browser however they see fit, and it only takes a few mouse clicks to do so.
Well move over Mozilla, and make room for Google Chrome. Why is that? To start with, Google recently added extension support to Chrome, which was previously only available in beta builds. Now that Google has given users the green light to install third-party add-ons, it's a brand new ballgame in the browser world. And in case you haven't heard, Chrome also supports Greasemonkey scripts, of which there are over 40,000 to choose from.
But those aren't the only reasons to give Chrome a second look. Google continues to tweak the underlying code and add features to what's already a fast, lean, and intelligent browser. Chrome is also highly tweakable, though you wouldn't know it by glancing at the sparse interface.
On the following pages, we'll show you how to soup up Chrome so you can leave Firefox in the rear view mirror and never look back!
Micro-management just isn't Microsoft's thing. Why do we say that? It's because the folks from Redmond are regular Babe Ruths when it comes to coding an OS and knocked the ball out of the park with Windows 7. But when it comes to integrated apps -- all those things we would expect Microsoft to excel at -- the software giant is more like Casey at the bat and we're all just a bunch of Mudville suckers wondering how Microsoft manages to whiff it at the easy pitches. Internet Explorer? Most of us are rocking Firefox or Chrome. And while we don't want to be too hard on Windows Media Player, there are certainly better media frontends out there.
One of them is XBMC, an open-source project formerly known as Xbox Media Center. XBMC was originally developed for the first Xbox console, and through the years, it has evolved as a fully fledged, cross-platform media hub with a rabid following and plenty of user-created plugins and scripts. It's also given birth to more familiar projects like Boxee, Voddler, and others, all of which initially borrowed from XBMC's source code.
If you've never played with XBMC, it's time for a test drive. To help you kick the tires, we've assembled 12 terrific tips and tricks so you can spend more time cruising the media byways and less time fumbling with the controls.
