Step2: Use the Zoom tool (circled in red at the left) to fill the screen with the teeth you will be working on.

Step3: Polygonal Lasso tool settings We will use the Polygonal Lasso tool, set the settings to match the picture at left

Step4: Selecting with the Lasso tool use the Lasso tool to select teeth. (The lasso tool works by starting at one point and doing quick click → release → drag → click → release → drag and clicks all the way around the object you want to select.)

Step5: Layer in the Menu at the top Click on "Layer" → "New Adjustment Layer" → "Hue/Saturation"

Step6: New Layer box New Layer box will pop up, just press "OK"

Step7: Hue Saturation Menu on Yellows Hue Saturation Menu will pop up on the right. On the Hue Saturation Menu change to yellow and use the sliders to adjust the color of the teeth. Click "OK"

Although it is expensive, today it is considered an essential program for anyone working with graphics, whether it’s in print, on the web, or even in television and movies. This has led to a huge number of cheaper competitors (who have been largely ignored), as well as rampant piracy of Photoshop itself. To counter this, a cheaper, simpler version of Photoshop called Photoshop Elements is now available, which is especially good for beginners.

How did Photoshop get into this dominant position? Well, development started in 1987, with the first release in 1990. Since then, Adobe has been improving the software continuously, constantly taking advantage of advances in hardware power. Even now, to get the best performance out of Photoshop, you should buy as much RAM as you can afford.

It is not just Adobe’s efforts that have got Photoshop where it is today, however. The program’s plugin architecture has allowed there to be are all sorts of plugins available for more advanced work, including some plugins that actually cost more and do more than the program itself. In this way, Photoshop is often used much like Windows, as a platform – and it would be a huge effort to get these plugins to run on any other software, making competitors effectively useless to anyone who relies on a plugin.

Today, you can get Photoshop for Windows and Mac OS (both OS 9 and OS X). If you want to use it on Linux, however, you will have to use Crossover Office, Codeweavers’ program that allows some Windows software to run on Linux, but it will be quite slow

So today I’m going to run you through the very quick process of backing your images to disc with Adobe Elements.

First I would recommend that you back up to DVD rather than a CD. Your first step is to select Organizer’s File Menu in the top right hand corenr and then choose Back Up Catalog to CD, DVD or Hard Drive.

You’ll than be given a dialog box, you are given some more options here, you can either do a full back up (you should do this option if it’s your first time) or you can choose Incremental Backup (you only choose this after your first backup because this option only backs up your new changes from your last backup). So if it’s your first time make sure you choose “Full Back Up”.

The last step is very simple and straight forward. All you have to do now is click Next and your destination settings screen will appear, here you are telling Elements to backup your stuff. Now it’s up to you if you choose to backup to CD, DVD or external hard drive. Like I said before we are going to be doing this with a blank DVD, so you just need to insert your DVD and choose that drive from the list. Make sure you give your DVD a name and then click the Done Button and that’s it.

So what does each of these do? Hue allows you and gives you the ability to change the images physical colour. Saturation, will this allows you and gives you access to control the amount of colour. Lightness, well this speaks for it’s self, it allows you to determine the brightness of the colour, but this is based on Hue and Saturation.

So how do you use the Replace Colour Adjustment?

The first thing you need to do is open Elements, then open you colour image. Next you need to click on Enhance Menu, the click on Adjust Colour and then click on Replace Colour.

Next you’ll see a Preview box you need to make sure this is ticked. Then you need to click on your active image with your selection eyedroppers to select, add or subtract colours.

Once you have done that, you then need to click on the Colour Box to select the colour which you’re after. Then drag the fuzziness slider which you’ll also see, you can drag this from right to left, this will increase or decrease the sensitivity of the eyedropper tool.

Now you need to click on your Selection or Photo/Image option to toggle between a view of the selection mask and the active image, you’ll notice that the white areas are the active ones. Then you just need to drag the Hue, Saturation and Lightness sliders to give you the right colour.

In elements 6 the brightness and contrast adjustments performs a linear adjustment for your new image. When you open the brightness and contrast adjustment you’ll see a slider bar, if you want to increase the brightness just move it to the right, this will increase the pixels within your image. This works for both brightness and contrast.

You might not know this but photographs are not linear in nature, so it’s best to use Curves and Levels (non linear). So if you are going to use brightness and contrast I would recommend using this on clipart text and clipart images, or just non photographic images or photos.

So to use brightness and contrast you need to open up Elements and then select your image. Your next step is to click Enhance menu, you’ll then have a drop down, you then need to select Adjust Lighting and the select Brightness/Contrast. Now make sure you have the Preview checked, this allows you to view your changes on your active image. To alter the Brightness just slide it to the right to increase the Brightness values, or just slide it to the left to decrease the Brightness values.

To alter the Contrast you need to slide the slider bar in the way. To the right increases the Contrast, to the left increases the Contrast. Once you are done just click OK.

By default Elements histogram displays the tonal range of your entire image. But you also have the option of using the selection tools to select a portion of your active image, so this way you can see the histogram for that portion.

The tonal range and colour values within Elements are really important to generate your great graphics which you are after, plus you can also see in the histogram palette your instant up to date information, you are given the option to view to specific pixel or range using Elements histogram palette.

If you want to view this information on the range of values all you need to do is drag Elements histogram into Elements highlight range.

Ok let’s have a quick look at how the Histogram works;

The first you need to do is launch Editor, then click on the Window Menu and then click on Histogram. Next you need to click the Channel list arrow, you’ll then be given a list of different colour channels which you can view your histogram in.

RGB – This displays the tonal range for Red, Green and Blue.

RED, GREEN AND BLUE – This just displays the tonal range for Red, Green and Blue.

LUMINOSITY – This is for lightness

COLOURS – This just displays the tonal colour range.

Next you can click the source list arrow you can see underneath the Histogram. You then can select your image source. Which include the following. Entire Image, Selected Layer or Adjustment Layer.

If you wanted to refresh your image cache just click the Uncached Refresh button. You can also view information about your range values, all you need to do is drag the histogram into the highlight range.
