Hello Students,

Your new assignment is to enhance your best portrait that you took during your recent photo shoot yesterday. Read through the color enhancement assignment and find a way to enhance the colors in your image to make it rich and vibrant. Next try the process listed afterward to modify additional images using the cross processing, tilt-shift affect and the "Dragan"method to create deep shadow and gritty detail in your images.

Color Enhancement Assignment:

• Choose your best portrait from your photo shoot yesterday and create a copy of it, open the copy up in Photoshop
• Read the entire tutorial below and try each step out on your photo
• Boost the color and depth of the photo with the tricks outlined in the tutorial
• Create an image border
• Add your first initial and last name to the lower right corner as a watermark
• Post the original and enhanced versions to the class site
• Pick 3 more images and follow the steps to create a cross processed image, a tilt shift affect and one that demonstrates the "Dragan" process

Color Enhancement and Photoshop Basics:

For many beginning photographers, any version of the image editor, Photoshop, can look quite daunting to use. With all the menu options, palettes, tools, filters, layer styles and various changes you can make to an image, it’s difficult to know where to start. This article provides some ways to get started with the most popular image editor in the world.

Here’s a copy of the original image used in this introductory photoshop tutorial. Notice it’s lacking control and saturation of color. It’s a little flat.

To get started, simply open a portrait or facial shot similar to the one I’m using here.

1. Duplicate The Background Layer

The first thing you want to get used to doing is making a copy of the background layer of your image. The Layers palette should open by default, but it is also found by clicking onWindows>Layers in the menu bar of Photoshop.

Select the Background Layer and click on the little triangle at the top right of the palette. When the palette options open, click Duplicate Layer, or you can use the shortcut keystroke, Command+J.

By duplicating the background layer, you can make all types of adjustments to duplicate layers without permanently changing the bottom background layer. If you make some adjustments you don’t like, you can drag the duplicate layers (with all the adjustments and effects you made to them) to the trash at the bottom right of the layer palette.

2. Automatic Image Adjustments

When you start learning how to use Photoshop to improve your photos, you might want to try out some of the automatic adjustments that can be made, even if you don’t understand the tools themselves.

The basic image enhancement and adjustment tools in Photoshop are found underImage>Adjustments in the menu bar. In the Adjustment palette, there are various tools likeLevels…, Auto Contrast, Curves, Brightness/Contrast.

To introduce you to these adjustment tools in this introductory photoshop tutorial, I’m going to suggest that you use the automatic and preset features of these tools. As you begin to understand them more, you will make use of manual adjustments.

So with your background layer duplicated and selected, click on Image>Adjustments>Auto Levels in the menu bar. When you release the mouse of the menu item, the automatic Levels adjustment should enhance or at least affect the shadow (dark), midtones, and highlights (bright) areas of your image. Often, a photo can be improved in Photoshop with just the automatic adjustments applied.

3. More About Layers

Now let’s revisit how layers work. Go back to the Layers palette and click on the little eye next the Duplicate layer that you just applied the Auto Layers adjustment to. When you toggle that little eye off, it means that you’re turning off the adjustment or effect that you made in that layer. Since the adjusted layer is on top of the background layer like a clear transparency, you can toggle the eye off and on to see how the adjustments are applied to the background layer (also remember: you can drag the duplicate layer to the trash to get rid of the adjustment(s) all together).

4. Automatic Curves

Okay, let’s return to a few other automatic adjustments and enhancements you can make to your photo. Go back to Image>Adjustments and then click on Curves. The Curves box will open. This box may look seriously scary with its grid, points, lines, and ear droppers. But don’t worry about that. We’re simply going to use some automatic adjustments to see how Curves can impact your photo.

Click on the button next to the word Preset. In the drop-down box, select Medium Contrast (RGB). If you don’t see much of a change in the contrast of your photo, go back to the Preset button and try Strong Contrast. You should be able to see the effect of the Preset on your photo before you click OK. Curves works similar to Levels but with more intensity in contrast.

Much more could be said about Curves and Levels, but this is just an introduction. You can play around with the points in the Curves box and see how they affect your photo. Remember, the changes you make are non-destructive to your photo, so you can experiment as much as you like. The illustration below explains a little about how the three main points in the grid function. If you make a mess of things, simply click Cancel and start over, or click OK when you’re satisfied with how the photo is looking.

5. Make Colors Pop

Okay, now lets move on to learn about other enhancements that can be made. One of the tools I use on nearly all the images I bring into Photoshop is one called Soft Light. Here’s how it works.

Go back to the Layers Palette, drag all the layers, except the background layer to the trash. Click on the Background layer and create another duplicate of it. Now click on the Normal button at the top of the Layers Palette. In the drop-down box, select Soft Light. When selecting this adjustment, it should make the colors of your image pop, or at least intensify the contrast of your images. The contrast of most digital images always need to be improved. This technique does that job extremely well without too much loss to detail.

If the Softlight application is too strong, select the Opacity button at the top of the Layers Palette and decrease the opacity of the layer/effect.

6. Image Border

Another tool that beginning Photoshop users might want to know is how to add a border around an image. Again there are a few ways to do this. One way is to select the top layer in the Layers palette. Next click on Image>Canvas Size. In the dialogue box that opens up, change the Width and Height to both to .2. Choose a color for your border. Make sure the center of the Anchor box is selected. Click OK and you should see a border around the image.

3 More Flavors of Post Processing: Cross Process, Tilt-Shift and Dragan Method:

Take your favorite images from your recent portrait assignments and create 3 different versions of each image by working through the online tutorials posted below. Post your 9 post-processed images to your blog when complete:

Cross-Processing:

Cross processing is an effect where the film is developed with the wrong mix of chemicals. Work through the tutorial to recreate this effect and make your photo look like it's source was film and not digital. The border around the film is called the "film rebate". Search for one on google images to use on yours.

Tilt-Shift:

Tilt shift photography is a technique where the lens angle is changed to create a focused center area. This tricks the brain into thinking it is seeing something very small. This is the effect we see when we squint our eyes at a small object.

Dragan Effect:

Andrzej Dragan's photography is known for having an intensity in detail and tonal depth. Try to mimic his technique with photoshop by working through the video tutorial.
