o you bought a new PC for yourself or a relative during the holidays. There was the initial excitement about its speed and the nice screen – and then it came time to actually get it running. Which meant embarking on some real work -– downloading a browser, a couple of multimedia players, a PDF reader, a toolbar, and maybe something for voice and instant messaging. Don’t forget the anti-spyware and anti-virus apps – you’ve got to have those. Hours, maybe even days, go by. How many wizards have you clicked through, not to mention license agreements and preference pickers? And then you have to ask: did I get everything? And how am I going to keep all of this up to date?
This has been my experience too many times. I wanted to simplify the project. This led me to Google and Google Pack– a one-stop software package that helps you discover, install, and maintain a wide range of essential PC programs. It is easier for everyone. And it’s free.
It downloads in minutes and installs in just a few clicks. There’s only one license agreement – and no wizards. And there’s a tool called the Google Updater that keeps all the software in the Google Pack current. Even if you already have some of the software in the Pack, you can use the Google Updater to update and manage it.
And now the question for you is: what will you do with all that time you’ve saved?

I’ve been shooting with digital cameras in my portrait and wedding photography studio for about five years now, and in that time I’ve taken well over 50,000 exposures.
Our studio has been around for about twenty five years, and it is busy, so creating a digital workflow that made sense was essential to not only our sanity, but our bottom line as well. After all, we’re in business to turn a profit, and time is money.
One of the reasons this is so important is because so many photographers get bogged down and stuck in time wasting systems, systems that are over complicated and too “perfect’. In the real world, where real clients pay the bills, and making them happy on a consistent daily basis is critical, getting the job done as fast as possible is essential.
Let give you a “snapshot” overview of our digital workflow. You should know that all the stratgies we’ve created in our studio are not new. They are essentially the same as when we shot film. Nothing has changed, except the media, the turnaround times (faster, much faster!), and, of course, the huge learning curve. Which we’ve over-complicated beyond anything that makes sense.
Funny thing is, I’ve come to realize that the learning curve is quite small when you do only the things required and when you use only the essential tools.
Here are the seven steps to digital photography workflow:
1-Good capture: This is the starting point. Without a properly exposed file and good color balance, you are in the “taking corrective measures” mode. You don’t want to be there. In time you would go crazy if you had to “fix” every file, so you need to master these two basics. Good photography and fast, painless workflow starts with good exposure and good white balance. A good exposure means you have as many of the tones, from the blacks all the way to the whites, in the image. The middle tones are exactly where you want them to be, in the middle. How can you check this? Shoot a grey card, and check your histogram of that grey card image in Photoshop. The levels should show you most of the data in the middle, or very close. If you are off, you are either over or under exposing your files and you are asking for trouble. Your white balance should be neutral, with no color cast. How can you verify? You should first of all should be creating a custom white balance for each lighting scenario. In our studio I created a custom white balance and never change it. It works all the time because the lights and the studio setting is consistent. On location each scenario requires a custom white balance. It’s very easy when you get the hang of it.
To check that you are getting a fairly neutral image from you custom white balance, again, shoot a grey card, in Photoshop use the color picker, and the RGB numbers should all be very close together. This means your image is neutral. If any of the RGB numbers are way off, you have a color cast in that direction. Master this and you are 90% of the way to success.
2-Adjust contrast: For many images we hardly do much contrast adjusting. Sometimes we slightly “tweak” the file in levels, but you can easily get carried away here and ‘over process’ the image. When you do that, there’s no turning back. It’s like over-cooking a steak. Too late, once it’s cooked. So be careful here.
My rule of thumb? Less is more. If you have to ask yourself “Does this need more contrast?,” then you’re done. STOP! But I do a step before anything else, and it does adjust the contrast as a side effect. You will never hear about this in any digital photography course or book. As a matter of fact, they will (”they”, being the “experts”) likely frown upon this step. Try it anyhow. We do, on every sinlgle image we work on. And that’s a lot of images. Here it is: In Photoshop go to Filter/Sharpen/Unsharp mask. Apply the following settings: Amount 60 Radius 20 Threshold 0. See how it removes the haze? Cool uh? And it just beefs the image up a bit. Now this filter is also used to sharpen image, but this step is not a sharpening step. We call it the de-fog step.
3-Enhance the skin tones: For all you nature and scenic photographers this step may not apply. But try it anyhow, it may help. The idea behind it is to bring out the reds in our skin tones, for all skin types. In the good old days of retouching by hand, we used to finish the print off with a layer of red.
This always brought the final steps of those long tedious retouching by hand steps together just nicely. How do we do this? Simple. In Photoshop go to Image/Adjustements/Selective Color. You will notice that the red channel is the default chanel. This is the one we want so don’t switch. Pull the top slider, Cyan, over to the left, and watch the colors, especially in the skin, warm up. Adjust it to your taste. We find that most images are within the -20 to- 40 range. That’s it! Assuming you have a good exposure and good white balance, this is the only color “enhancing” you will need to do.
4-Adjust the saturation: When I shoot I turn the cameras’ sharpening, contrast and saturation features off. I don’t want the camera doing any of these important steps for me, since every image requires a different amount in order for it to be optimum. The images that come off the camera tend to look a little flat, dull and sometimes not sharp. But that’s good! I get to adjust these myself.
The saturation will add a whole lot of life to your images, if done properly. Again, less is more. Here’s how: In Photoshop go to
Image/Adjustements/HueSaturation and pull the middle saturation slider over to the right. It helps if you enlarge your image so you can really see this effect and not over do it. This works very well on scenics and underwater images as well. But be careful not to over process. Remember, less is more.
5-Burning and Dodging: Over and over, I see it all the time. Using the right amount of good old fashioned burning or dodging and you will take your images to whole new level. It isn’t easy to master however. Way back when I started out in photography, my mentors and early instructors were well versed and skilled in the ways of this traditional application. They knew and valued the importance of an image that was properly worked. The rookie mistake I see over and over is either not using enough (or none at all), or using too much. It takes some doing but this skill is worth mastering. Here’s how: On the toolbar in Photoshop, click on the dodge/burn tool. It has both. Burning is by far the one you will use the most. When you select burn, the control bar accross the top will allow you to set the brush options. These settings are vital to your success. First, select a soft brush. The size will depend on the area you are burning. When I am burning all around an image, I generally choose a larger than the image area size. Next, choose Highlights in the range options. Next, bring your exposure down, way down to about 20. Now you are are ready to do the first step. Burn all around a few times, and stop after you notice a very slight darkening. Next, switch the Range to midtones. The first step, in highlight mode in the Range bar, gives your image some teeth for the next step. Now burn around again, careful not to over do it. The success of proper burning will depend on how well you can achieve an almost imperceptable dark vignette look to the image. If it’s too obvious, then you’ve over done it. I should point out that this is not recommended for white or very light images.
6-Sizing: Almost done. We size two ways. For prints smaller than 11″x14″, we use the crop tool and simply crop and save as required. For larger prints we use a technique that will magically increase your images to just about any size without any virtual deteriotion. Here’s how. In Photoshop go to Image/Image Size. In Document Size, switch the option in the drop down menu from inches to percentage. Only do this on the top “witdh” option: replace 100% with 110% and click okay. Make sure Constrain Proportions and Resample Image options on the lower left are clicked on. The image will increase in size by 10%. Do this until you have reached the size you want. It’s amazing! Virtually no deteriotion at sizes up to and beyond 40 inches. Try it.
7-Sharpening: This is the last step, well, almost. My sharpening approach is not something you will hear about in any course or book. Again, I figured out what works, and what works best. I was able to get tack sharp images from file sizes as small as 3.4 MP. Here’s how: Go to Filter/Sharpen/Unsharp and start with these settings: Amount 500%, Radius .2, and Threshold 0. Click on preview. Highlight the Radius number and start to increase that number (I use the “up” arrow on my keyboard) one step at a time until the image slightly “pops”. That’s when it’s done. If it pops too much, bring it back one number in the radius. I don’t even touch the other two settings. They will not recommend this technique in any course or book, but it works in the trenches. I’m sure it breaks all sorts of rules. The final step for all images is by to Filter/Noise/Add Noise, and set the amount at 1. Why do I do this? It gives the image a slight texture, a little bit of “love”.
That’s it! In a nutshell. From the trenches. There are more technical and highly advanced ways of getting these steps done, but frankly, in the end, you won’t see the difference. I know, I tried em all! Fact is the only expert in the game of portrait photography is the client. All she cares about is great looking images. She doesn’t care if I shot using RAW mode (which I don’t by the way, always JPEG). She doesn’t care how many megapixels I use. She doesn’t care what kind of lights I use, how I workflowed my images, whether I did them on a MAC or a PC (PC by the way). She ultimately is the final judge and jury.

Open Source Software and its Relation to osCommerce
Open Source Soft and its Relation to osCommerce
E-commerce sites such as osCommerce function through the use and continued success of open source – in fact, open source software is what makes these sites free. So what exactly is open source ? The purpose of article is to help you better understand what open source is.
Basically, open source is
based on the idea that when people have access to a software’s source code they
can change, improve and evolve a piece of at astonishing speeds – a
characteristic that ends up produces really great that meets the needs
of its users.
Open source software is not just free code for website and .
Open source software is “governed” by the Open Source Initiative. According to the website for the Open Source Initiative it must meet several criteria to actually qualify as open source:
First of all open source must not restrict anyone from selling (or giving away) the
software. In other words, it cannot require a royalty or fee. For a product to be open source, it must also provide the source code so that the users can easily evolve the software to fit their needs and any software created with free programms must be free as well.
Furthermore, open source software distribution cannot discriminate against people or fields.
So, how did this concept begin? Most experts on open source software will agree that the concept of open source soft began with the creation of the internet which was created and improved upon by it’s users who continually changed the code to make it work for them.
Then, when computers were first used, programs were often sent as a printed version that had to be
entered into the computer line by line. Programmers not only entered the programs onto the computers, they also were able to “play” with the programs and make changes as well as share there ideas with others.
Once computer became more mainstream and people other than programmers began using programs, the need (and desire) for the source code declined. This is when software companies began realizing the economical benefits of keeping their source code for software private. This also began the influx of new and incompatible operating systems which further declined the ability for programmers to share and collaborate with one another. While there are benefits to creating and selling software in this manner, some programmers realized the limits this posed on the usability of the
software.
Without keeping the source code open, the users were bound to the limits of the soft and were not able to alter it to fit their individual needs. This is what began the development of the GNU Public License operating system for open source soft. The premise behind renewing the concept of open source software is that programms development would be faster and more efficient in giving people the programs they need and want to use.
Today, open source software is becoming more and more mainstream and is used quite frequently on the internet for websites and browsers.
How does it all relate to osCommerce?
Obvious by its name, osCommerce is based on the concept of open source software. This means that osCommerce is free to use and the community members can feed off of one another to continually develop the code that they use. The store owners don’t simply purchase a software program (such as a shopping cart code) that they need to implement as is. They can
design, develop and evolve their store presence to meet their changing needs. The beauty of open source code in a situation such as this is that the members of the community can help one
another develop new code on an ongoing basis.
