Bring out the Gimp

This week’s episode is another homage to free software. For starters, Gimp has arrived, courtesy of Aaron Voisine. But, the fight is not over. We’ll also look at a live battle for OS X compatibility, as we work to get a popular new P2P internet phone app made for Mac.

mu Bring out the GimpGimp.app

Between OpenOffice and Gimp, many argue there’s no need to pay hundreds for software. This version of Gimp comes packaged in an Aqua-like theme and packs new features. Today it works with Panther, Jaguar compatibility is on the way.

It is doubtful that Adobe sees this as a threat to Photoshop, which recently reeled in record profits for the company with its new CS version. Photoshop will likely out-feature Gimp for the foreseeable future.

But Gimp does bring an element of freedom to users who don’t yet have the free cash to own the best, and are happy for a free alternative. Free software opens doors, and the efforts of the many who contribute to the project are more than appreciated.

Upgrade your graphics power, or get yourself a powerful backup. Either way, Gimp is worth the download.

Skype

Peer to peer telephony is what they call it. A long-awaited, quality successor to DialPad is another way to describe Skype. But, with a Mac OS version mentioned only as a possibility, you may not even have a chance to try it out.

Thanks to Jack Arends for the heads up on this one. The coming of a Mac version of Skype my be in your hands. Send feedback to make sure the makers of Skype know that there is interest and you can help ensure that Skype comes to the best OS there is.

Doesn’t free software make the Mac OS a great place to be? More next week.

A Brief History of Free Software (Part 1)

This week, we’re going to try something a little different. Rather than enjoying free apps, we’re going to learn about how freeware came into being and how you can contribute the movement. Hopefully, this brief history lesson will be more interesting than you expect. You’ll see some familiar faces and better understand the lingo of Open Source.

In the Beginning, all Software was Free

We all know something about the early days of the mail-order home PC. Much of the software development for these early machines was written and shared in user groups. Among other Apple soon-to-be’s Steve Wozniac was a high profile figure. In these groups, software hackers came in with their source code and openly shared their work in hopes of forwarding the small movement of home computer hobbyists. One notable figure missing from the fun: young Bill Gates. Though an early part of Silicon Valley, this young enterprising enthusiast sought to introduce the concept of coding for money.

Freeing UNIX

On the corporate/educational front there were also early divisions on paid versus free software. AT&T created UNIX, but by the 70′s many of the utilities and additions to UNIX had been created by contributing academics. These students and professors wanted their work to be free. AT&T was of the same school of thought that Gates was. To solve the problem, professors organized a tremendous volunteer effort to recode the AT&T-owned portions of UNIX. Their product was a free version of UNIX that lives on in FreeBSD, OpenBSD and Apple’s Darwin.

Protecting Free Software: the GPL

Other coders who wanted their hard work to remain free devised the Free Software Foundation, GNU (GNU not UNIX) and a new kind of software liscence: the GPL (GNU Public License). Unlike Berkley’s “free to distribute” license, the GPL goes one step further. Software published under the GPL must be free and include source code. Also, any additions to the software must also be made available free. This protected the work of good-will programmers that didn’t want a company capitalizing on their hard work.

The Free OS

Under the protection of the GPL, Linus Torvalds created, and maintains today, the Linux project. I say maintains because, thanks to the protection of the GPL hundreds of programmers and dozens of companies have contributed to Linux. Now, as Mac users we tend to see Linux as a threat. Nothing could be farther from the truth. One of the core values of GNU software and Linux is portability. This includes efforts to maintain Linux and GNU software for the on the PowerPC processor as well as porting projects like Fink. With OS X’s core (Darwin) a close cousin of Linux, we can enjoy the products of the Linux movement too.

Free as in Beer, Free as in Freedom

Open Source software is about more than free code. GNUs define two types of freedom – free as in beer (free to download and guzzle) and free as in freedom (free to modify the source code, free to distribute). The later type of free may not seem as important – but it is.

Contributing to Open Source

Inspired by the idea that software should be free? Eager to join the army of hobbyists and professional coders? Don’t know a thing about coding? That’s okay. In fact, what many say is a weakness of Open Source software is a core strength of many Mac users: design. Along with contributions of art, an eager Open Source supporter can contribute in may ways:

  • GUI/Theme/Template Design
  • Marketing, Evangelism and Promotion
  • Contributions to Documentation
  • Help in Support Forums

The beauty of community build software is that projects from Mozilla Firefox to tiny Mac freeware apps are inclusionary and always looking for help.

Conclusions, Part 1

Okay, that was a lot of background. But I think it is worth knowing about the origins of free software and the ties it has to the Mac. In a couple weeks we’ll continue our discussion of free software by highlighting its future. We’ll talk about how you can still make money with free software and we’ll identify some of Open Source’s friends and foes.

Until then, long live free software!

Experimenting with Adobe Photoshop CS3 (Comic Effect Deconstructed)

(from Episode #74 of The Lab with Leo Laporte)

finish 20070912 143158 Experimenting with Adobe Photoshop CS3 (Comic Effect Deconstructed)

S.C.A.M.P.E.R.
Photoshop is supposed to be a creative outlet, right? But it has so many features and settings that sometimes we’re so overwhelmed that we become afraid to just play with it. We might have an effect in mind and we search the internet for it. When we find it, sometimes it’s not what we have in mind or often we don’t find it at all and we just give up. “Photoshop can’t do that.� we tell ourselves.

We have to give ourselves the freedom to play and we have to give Photoshop the freedom to do things that it was never expected to do.

For instance, Photoshop has a Photocopy filter, right? Have you ever tried using it for something other than making an image look like it was photocopied? Give it a chance! Most of Photoshop’s filters can be adjusted to the degree where the effect they produce looks nothing like what its label in the Filters menu would have you expect. What is important to note in those situations is not that the particular combination of settings doesn’t look like a photocopied image, but what does it look like? What effect can you use this combination of settings to achieve?

Don’t be held back by the labels on the menus!

This kind of thinking can (and should) be applied to Photoshop tutorials you find online and in books as well. Follow the tutorials as they were written and see how the effect materializes as it was intended by the tutorial’s author. But then, after you’re familiar with what it does, play around with the tutorial a bit and see what else comes out of it.

Here, we’re going to take my Comic Art Effect tutorial and apply Alex Osborne’s S.C.A.M.P.E.R. principle to see what other effects we can make from it.

start 20070912 143032 Experimenting with Adobe Photoshop CS3 (Comic Effect Deconstructed)

S.C.A.M.P.E.R. stands for:
Substitute
Combine
Adapt
Modify
Put to some other use
Eliminate
Rearrange

A brief Breakdown of the Comic Art Effect
This is an effect is based on a Tone layer and a Color layer to approximate the coloring of a vintage comic book illustration and 3 Ink layers to give the effect of “hand drawn� outlines and shading. At the end of the tutorial he recommended adding another color layer to tweak skin tones that may have gone astray, a white layer to brighten teeth and eyes, and a dot screen layer to give the image that course dot pattern associated with old comic books.


substitute 20070912 143459 Experimenting with Adobe Photoshop CS3 (Comic Effect Deconstructed)

Substitute
Try Substituting different filters in tutorials. In the case of this tutorial, you might substitute the second and third Ink layers with one where you have copied the original image to a new layer above Ink 1. Set the new layer to “Multiply� with an opacity of 50% and then apply Filter>Sketch>Graphic Pen using the settings 15, 43, Left Diagonal. It gives a much softer illustrative effect.


combine 20070912 143624 Experimenting with Adobe Photoshop CS3 (Comic Effect Deconstructed)

Combine
If you have Adobe Photoshop CS3 as part of a Creative Suite bundle, you probably have Adobe Illustrator CS3 as well. Why not combine its abilities with Photoshop to create effects that could not be achieved using either application on their own? He had saved a copy of my finished Photoshop Comic Effect where I turned off all of the Ink layers and saved it as a flattened TIF. He then opened that TIF in Illustrator and used Live Trace to simplify the colors to look a bit like and Andy Warhol pop-art painting.


Adapt
If you look on MacMerc.com, you’ll find that this tutorial has been Adapted for use as a Photoshop Action. It has also been adapted for Adobe Elements. If you don’t happen to own Adobe Photoshop, that shouldn’t stop you from enjoying a free open-source creative outlet—namely, Gimpshop! I unfortunately haven’t adapted this tutorial for use with Gimpshop but that’s only because I have Photoshop. I welcome and encourage any of you Gimpshop experts out there to take a crack at the Comic Art Effect and and let me know how it goes. I’d love to link to your tutorials!!


modify 20070912 143813 Experimenting with Adobe Photoshop CS3 (Comic Effect Deconstructed)

Modify
Photoshop has long offered non-destructive ways of modifying an image; affording safe experimentation where any mistakes or undesired results are entirely reversible. Once you’ve finished a tutorial, don’t be afraid to go over it again and change the filter settings. Use Smart Filters, if you can, and then you can go back again and again and try new effects and settings. Layer Masks and Adjustment Layers also allow for experimentation.
I have added an Adjustment Layer to my file to cycle the color of my image through the rainbow to create a psychedelic result.


Put it to some other use
Who says Photoshop has to just be for static images? Go to video! After all, video is just a string of still images strung together and displayed in quick succession. Look at what one person has done using the Comic Art Effect tutorial (click to view video above).


eliminate 20070912 143959 Experimenting with Adobe Photoshop CS3 (Comic Effect Deconstructed)

Eliminate
For “Eliminate,� try turning off all but the Ink layers. For many photos I’ve tried this effect on, turning off everything but the Ink layers creates and pretty cool looking illustrative effect. This was the inspiration for my Frank Miller Sin City Effect.


Rearrange
While my experiments with rearranging or reversing the Layers and steps of this tutorial didn’t return any pleasing results, the technique of Layer shuffling often does produce new and interesting effects that you can call your own.


Conclusion
So, bottom line, I hope you’ll be encouraged to play a bit with Photoshop and apply the S.C.A.M.P.E.R. principle. The only way to feel comfortable using any software is to become familiar with it and an excellent way to do that is to explore and experiment.
Have fun!!
