If you read my recent post about taking movies with the iPhone 3GS, you probably noted that I talked about the lack of editing capabilities on the iPhone with the exception of trimming the beginning and ending of your videos. What if you want to edit your movies, add titles or effects, or combine a bunch of short iPhone video clips?

Several of the comments left by TUAW readers asked the same question, and it's so easy to do that I decided to whip up a quick tutorial showing how this works. You probably have a tool on your Mac that can do the job for you with just a few clicks, drags, and menu selections. iMovie is the perfect easy tool for creating full feature films (just kidding) from individual scenes shot with the iPhone 3GS video camera. Here's how to do it.

If you've always wondered how to draw a "ball of nodes" as featured in a variety of Mac OS X icons, wonder no more: Mike Rundle of flyosity.com has written a tutorial to show you how using Photoshop.

Rundle discusses "spheric realism," the process of understanding the materials, reflectivity, and roundness of a sphere, and how to accurately illustrate it digitally.

Clever users can easily adapt the technique for Illustrator, Acorn, or many other compositing tools that feature blur and blending mode support.

Rundle also offers a PSD file containing the artwork with no strings attached.

Thanks Todd!

Yesterday, I showed you how to simulate a photograph taken with a tilt-shift lens by using Photoshop CS3's Lens Blur tool. Today, we'll do something a bit more practical: clipping out an object that's not entirely in focus.

Clipping out objects that are out of focus can be something of a chore: either you have a hard, dark edge somewhere you don't want, or you have to settle for feathering the whole thing, leaving edges that should be sharp a little too blurry.

We'll be clipping out this old book, and dropping it on a new surface.

We all know Photoshop is a powerful tool. In two tutorials, I'll take you through how to use Photoshop CS3's Lens Blur filter to do two things: today, we'll make images look like they were shot with a tilt-shift lens. Tomorrow, we'll create clipping masks for objects that aren't entirely in focus.

Lens Blur gives the effect of a narrower depth of field, so some areas of your image stay in focus, and other areas are blurred. Combined with an alpha channel that defines areas of blurriness, you have a powerful way to create masks and alter photos.

The easiest thing to do is show you first how Lens Blur works in pictures.

Apple has posted a online seminar on using iWork '08 in a business environment. Presented together with Rebecca Breitenkamp, the CFO of a biotech company that uses iWork internally, the half-hour video goes over some of the basic ways that Pages, Numbers, and Keynote can be used in a corporate setting. It not really a step-by-step tutorial, but more of a series of examples of how well iWork functions on what many folks think of as Microsoft Office's turf.

To watch the video you will need need to complete a free registration.

Here's a fun little tutorial by Ged from Iconfactory, showing how to easily use icons (exported to a certain size) as contact images for the iPhone. His example is with the Dino-o-Matic icons from IF, which are (cheer!) free this week, but the fact is that this is a great idea for almost any contacts that you don't have a readily available picture for. You could use any icon you like, use Pixadex to get it in the right form, and then plug it right into your Address Book.

As Ged notes in an update, while this is perfect for iPhone, it could be used for anything, including just Address Book itself. Because why say with a crappy, out-of-focus picture what you could say with a beautiful icon?

Today with so many of us using our digital cameras to shoot short video segments, it's especially easy to forget that we're dealing with videos and turn the camera on its side for a portrait orientation. Unfortunately, most video programs are not set up to handle portrait video. The video ends up displaying on its side. QuickTime Pro makes it easy to recover from this kind of shooting calamity and restore the orientation you intended. Here's a gallery showing you how.

No doubt you know that sharing your internet connection on your Mac is easy. For instance, if want to turn any Mac with a built-in Airport card into a wireless router (e.g. with a cable or DSL modem plugged into the built-in ethernet port), all you have to do is go to the Sharing pane of your System Preferences select it and hit start. However, what if you want to do something a little bit more complicated? In this tutorial I'll cover some other ways for turning your Mac into a router, including over FireWire and adding a second ethernet port via USB (which can be really tricky).

When we posted about Part I of Scott Stevenson's Learn Cocoa tutorial, some people complained that there wasn't actually any coding involved. Well Part II at least introduces what Scott calls "Thinking in Code" and begins to dig a little deeper into what is required to actually use Xcode to write a Cocoa application. Obviously, Scott is moving very slowly, as yet again he requires no previous experience, but his lavishly illustrated guide is a pleasure to behold. He holds out the promise of more such guides in the future, provided some donations are forthcoming. Given how well he's done so far, I hope that comes to pass. Check it out at Cocoa Dev Central.

If someone you know just got their first iPod, you might want to steer them towards this free iPod Tutorial. In PDF format, this tutorial introduces new users to all the basics of iPod use from creating an account at the iTunes Store to using the Hold switch to iPod software updates.

The 27-page tutorial promotes NotePage's FeedForAll and RecordForAll iTunes-compatible podcast software. (They put links to the software and a logo on every page. It's not subtle.) Still, it's a pretty decent tutorial, especially for the price.

I found this OS X trash primer over at YouTube in the new video listings. For many of you readers this is going to be old news--how to throw away locked or busy files--but for those of you who are new to OS X and the Macintosh, you may appreciate the basic how-to steps that the video offers. You don't actually need a third-party product to dispose of an application, but many OS X users like to keep their systems clean and tight.

MurphyMac has posted a video tutorial showing how to customize your dmg containers to make them look more professional. The tutorial walks you through the steps of creating a disk image, adding a background graphic, and saving the result for production and distribution. A fully customized dmg file offers a polished presentation so you can really impress the people you're distributing your material to.

Prompted by a TUAW reader comment on my post the other day about some Quicksilver fundamentals, I thought I would take a crack at posting some short tutorials on what Quicksilver actually does, and how to get started with it. I'm talking about the most basic of the basics here for anyone who is curious but still confused as to what the heck they're looking at the first time they launch Quicksilver. To anyone who can't make heads or tails of it: I don't blame you. It took me quite a while to wrap my head around all this stuff, so I hope I can do you some justice with this post.

Disclaimer - I use a somewhat modified version of Quicksilver and I've added a lot of extras, but for this demo I *think* I've properly fixed my copy to look like a default Quicksilver install.

Speaking of my screenshot - let's get started.

Yesterday Quicksilver started acting a little goofy, and I wasn't surprised; I have just about every beta and extra turned on as I just can't stop exploring all the neat stuff this app can do. During my troubleshooting efforts I resorted to the simple trick of quitting Quicksilver and simply moving its preference file (located with other preference files in ~/Library/Preferences) to my desktop, forcing Quicksilver to re-create a clean new preference file. This fixed the issue, but it also forced me to dive back into my preferences to tweak, toggle and change some of the options I use to make Quicksilver do what I want.

That experience made me realize, however, that part of the Quicksilver learning curve for new users really is to get to know its preferences, since they act as a handy springboard into what Quicksilver is capable of. A lot of fantastic tutorials, like those at 43 Folders and Blacktree's own site (the makers of Quicksilver), sometimes assume that you already know what you're doing with Quicksilver. Another complication is that the actions (and sometimes plugins) used in these tutorials are not installed or enabled by default. Some of the email actions - for example the "send item immediately" action that allows you to email an item to someone without ever touching a mail composition window - are oddly not enabled in a default Quicksilver installation, which means a user has to open Quicksilver's preferences (once invoked, a quick cmd - , does the trick) and dig around in the Actions section to find what they need. Ultimately, I figure there are three key areas of Quicksilver's preferences that might help new or aspiring but confused users get their feet grounded: Catalog, Actions and Plugins, and here is a brief explanation of each:

• Catalog - this is a pretty straight-forward list of everything Quicksilver keeps track of on your Mac. Looking through the Catalog and the Actions preference panel should help you get a grasp of what items Quicksilver can find and manipulate, and then how you can manipulate them.
  
• Actions - this is a list of the defining ability that separates Quicksilver from mere seek-and-find applications. Actions allow you to do something with the item you have found, far above and beyond simply opening it. Actions are (loosely) categorized to help you find your way around: Address Book actions allow you to do more with your contacts, Text actions (an optional plugin) allow you to do things like looking up word definitions right from within Quicksilver and appending text to a file buried somewhere, etc. If this panel doesn't excite your inner productivity geek, you should consider consulting your physician.
  
• Plugins - Quicksilver is highly, highly plugin-able, which is where even more of its beauty radiates from. Plugins for Backpack, alternative browser bookmarks, the Mac OS X Keychain, NetNewsWire headlines, a multiple-item clipboard, hundreds of web search engines and much, much more all have your name written on them. Go wild.

Quicksilver is one of the few apps that is so different and powerful that the classic "just open and play with it" phrase might not be enough for some users to grasp what's going on. If you are one of these users, I hope this brief explanation will help you to take your first step into the wide, wonderful universe of Quicksilver.

Today I fall even more deeply in love with Quicksilver, as I have discovered yet another incredibly useful and productive trick from a 43 Folders tutorial. This easy tip, loosely called "the comma trick," allows you first to find more than one item with Quicksilver, then apply an action to all of those items. If you're wondering why or how this could be useful, consider a couple scenarios:

• You can find multiple bookmarks (as many as you want, as far as I can tell) and open them all in tabs (as long as your browser does the tabs thing).
• You could find a file, chose Quicksilver's "send immediately" action and then find multiple people from your address book to send that same file to - all without ever touching an actual email compose window.

This trick's usefulness boggles my mind, and all you really have to do is hit the comma key in order to chose multiple items. Check out the 43 Folders tutorial for the full deets on how this trick works, then feel free to take a break from being amazed.
