Over 2 years ago I wrote about an (almost) famous PCIN subscriber. This was (and still is) a friend of mine who got on the radio with a song his brother-in-law had written. Well, he's aiming a little higher now. She has put been successfully building up a children's dance class, and together they have written original songs for the classes. The are even heading to the studio to make their own CD. Impressive!
The March Break (Canadian equivalent of Spring Break) is coming up next week so Lisa is trying to come up with something she can do with the boys. I suspect she'll be playing with a lot of Play-Doh!

The rise of technology addiction
The seemingly exponential growth of portable technology has sparked fears that people are becoming addicted or swamped by gadgets and their uses.
One major consequence of this phenomenon is that the line between work and private life is much more blurred, now that e-mail and phones provide a 24-hour link between employers and staff.
Experts believe that even the decision-making process of the average person can be adversely affected.
Dell's Doubtful Turnaround
Struggling Dell provided a glimpse into just how difficult its turnaround will be, reporting disappointing fourth-quarter results that include its first quarterly sales decline in five years. Adding to the uncertainty surrounding the world's second-largest PC seller, the company didn't shed any light on months-long investigations by the Securities & Exchange Commission and the U.S. Attorney for the Southern District of New York into certain accounting matters, as some analysts had been expecting. Dell is conducting its own internal investigation.
Time Change a 'Mini-Y2K' in Tech Terms
Two years ago, when Congress passed a law to extend daylight saving time by a month, the move seemed a harmless step that would let the nation burn a little less fossil fuel and enjoy a bit more sunshine.
Representative Fred Upton, a Michigan Republican, predicted that children would rejoice at the prospect of an extra hour of daylight trick-or-treating on Halloween. But there is no rejoicing among corporate technology managers.
The change takes effect Sunday, as daylight saving time begins three weeks earlier (and ends a week later, on the first Sunday in November). And many companies are scrambling to reset BlackBerry e-mail devices, desktop PCs and big data-center computers used to automate payrolls, purchasing and manufacturing.
Adobe to take Photoshop online
Hoping to get a jump on Google and other competitors, Adobe Systems plans to release a hosted version of its popular Photoshop image-editing application within six months, the company's chief executive said on Tuesday.
The new online service is part of a larger move to introduce ad-supported online services to complement its existing products and broaden the company's reach into the consumer market, Adobe CEO Bruce Chizen told CNET News.com.
Chizen said Adobe laid the foundation for a hosted Photoshop product with Adobe Remix, a Web-based video-editing tool it now offers through the PhotoBucket media-sharing site.
Layer Masks - Digital Photography Tip of the Week
Both Adobe Photoshop and Adobe Photoshop Elements 5.0 are great tools that offer precise control over your photographs. Back in the days when I printed my own black and white photographs in my basement darkroom, I used tools for both burning and dodging (adding or holding back exposure) specific parts of my photos. Today's photo editors offer similar tools but with more precision. Layer masks are one of the tools that provide that precision.
A layer mask is a type of selection that maps which pixels will be affected by the modifications to the current layer. The advantage to using a layer mask instead of a normal selection is that is easily editable which allows you to modify the selection later on. Adobe Photoshop CS2 has full support for layer masks while Photoshop Elements only supports them on Adjustment and Fill layers. Layer masks can be edited by painted them. Portions of the mask that are painted black will not be affected while portions that are painted white will be. You can also use shades of gray to adjust the degree of adjustment. Before we begin with an image, let's get acquainted with a layer from our image.
From left to right, the first icon tells us this layer is visible in the image (not hidden). The second icon
indicates what kind of layer this is if it is an adjustment layer or will display a preview of the layer if contains
image data. The third icon identifies whether or not our layer mask is linked to the actual layer. If it is not linked,
the two pieces may be moved separately. The selected layer portion will be outlined when they are not linked. The next
icon is a preview of our layer mask. This particular adjustment layer will modify the entire image with the exception
of the subject in the image. Finally, the name of our layer. To add a layer mask to an image layer, press the layer
mask button at the bottom of the layer palette .
Now lets start with the following image, a portrait of my friend Dave shot in a dark alley with only the overhead streetlight for illumination.
Through a series of adjustment layers and layer masks, we will transform this flat image with poor colour into a nice black and white photograph. As I mentioned two weeks ago, my first adjustment is to set my white and black points using a levels adjustment layer. Because this layer will affect the entire image, I have not modified the default layer mask that accompanies adjustment layers, it is all white. Next, using a Channel Mixer adjustment layer, I converted the image to black and white and followed that with a color balance adjustment layer for more precise control of how the colors were translated into black and white. Again, both of these layers were applied to the entire image and so the layer mask is completely white.
I then began to add more adjustment layers to modify selected portions of the image. I used a curve adjustment layer for each of the subsequent modifications to this photo. I slightly darkened the outside of the image. This causes the viewer to focus in on the subject. I then created a new curves adjustment layer and with the paint bucket, filled the entire image in with black (not affected). Switching to a brush and changing my foreground colour to white, I then painted over the pants. With my selection complete, I was able to adjust the layer until I was happy with the look. I used the same process to lighten the shadow that fell on his face, then again to lighten the entire face. selected everything in the image except for Dave and increased the contrast of the image until I liked the result.
In this image below, I have turned of the adjustment layer where I modified the pants off so that you can see the difference. Note that the only the only piece of the image that is different is the pants.
Layer masks allow you to make non destructive edits to your image. These non destructive edits enable you to make changes to your image after without degrading the quality of the source file. The only time in the editing process that any pixels were actually modified was at the end when I saved the image to a JPG file. I can turn off all of the adjustment layers I have created and my original layer will remain unchanged from the point I first opened it.
Knowing how to maximize the quality of your image by using all of the tools available to you can help you create better photographs. With the help of layer masks, you can make multiple edits to your image, but be comfortable knowing you can change your mind later.
Until next time, Happy Shooting.

Shutdown Day
It is obvious that people would find life extremely difficult without computers, maybe even impossible. If they disappeared for just one day, would we be able to cope?
Be a part of one of the biggest global experiments ever to take place on the internet. The idea behind the experiment is to find out how many people can go without a computer for one whole day, and what will happen if we all participate!
Shutdown your computer on this day and find out! Can you survive for 24 hours without your computer?
It'll be interesting to see how many people participate in this Shutdown Day...
