Fear not, the world of Photoshop is less daunting than one may think. All you need is a computer, and according to a Opinion Research Corporation's CARAVAN poll, 76% of American adults own their own computer. It is also unlikely that you would be reading this Instructable if you didn't at least have access to a computer.
OK, now I will tell you EXACTLY what I will cover in this Photoshop Instructable!
-An in-depth look at the basic tools, as well as more advanced usages of these tools (marquee tool, zoom, move tool, quick select tool, crop tool, brush, and erase). I will use a possible Photoshop project to further explain the uses and importance of certain tools.
-I will also cover some tips and tricks that I have learned
Computer - You probably already have one of these
Photoshop - You have a higher chance of not owning this as it is quite pricey if you don't get a student discount.
Gimp - I know it isn't as good as Photoshop, but it is a FREE ALTERNATIVE to Photoshop, I have provided a link to their website.
If you find this Instructable helpful, feel free to visit my forum topic with other tutorials that I have created in order to help you figure out the basics of Photoshop. It is looking a bit sparse right now, but I plan on expanding in the very near future.
Step 1: And So It Begins: Getting Started
-Tip- If you copy an image from the internet, the size of the canvas will be the EXACT same size as the image you coppied. If you copy a 345x892 pixel image from the interwebs, that is going to be the size offered to you in the New... window.
I chose to re-size my canvas size to 1000x1000 pixels just to make it a nice box to put whatever comes to mind into it. I looked up puppies in Google images, and was about to make this Instructable about the basics of Photoshop, with puppies being my lab rats, but decided a car would be much easier for demonstration purposes. It is easier to Photoshop because you do not have to worry about hairs. I find Photoshopping something with hair to be more difficult, and not suited for a basic tutorial.
Once you find the right image, copy and paste it into the canvas (Ctrl+V for PC, Command+V for Mac)
Step 2: Tools: Move Tool (V) and Marquee Tool (M)
-VERY IMPORTANT TIP-Now before you do anything you regret, such as guessing the correct dimensions so as to avoid stretching the image, it is important to HOLD SHIFT before you start to drag the corner out. This will cause the image to scale properly without stretching the image.
Now that you have the image re-sized to the correct size, you can chop your image down to size with the Rectangular Marquee Tool (the shortcut for the Marquee tool is M). The Marquee Tool will allow you to create a box with marching ants (the moving dashes). You can then cut, copy, paste, or delete what is inside or outside of this box.
Once you have the Marquee tool selected, you can either...
A) hold shift and drag the box around your car to create a 1:1 ratio box
B) drag without the shift to make a non-ratio selection
C) OR look up in the Style drop-down menu, and select Fixed Ratio. With this selected, you can create a box who's ratio between sides will NEVER FALTER! I chose a 1:1 ratio in order to make a perfect square selection. This is shown in pictures 3 and 4.
Once you have what you want selected, you can right click the box, choose Select Inverse, and Command+X to cut away what you didn't originally select. You may be thinking "WHOA" after that last sentence, but don't worry, it is merely a way to delete all of the unwanted pixels outside of the original selection. This little move becomes useful when you want to get rid of a background or something big.
Step 3: Tool: Quick Selection Tool (W)
Oh... You're still here? Well congrats, you've survived the boring basics and now you can finally get into the slightly more complicated tools that Photoshop has to offer. The tool I'm going to show you will allow you to select pieces of an image based on that image's color and contrast.
In the first picture, I selected the Quick Selection Tool (W) and used it like I would a paint brush, painting above the car in order to select the background. As you may notice, Edit>Undo is your friend when messing about with the Quick Selection Tool (W). I was able to make the selection in the second picture with the help of the + and - brush options shown in the third picture. The + option will add to your selection, whereas the - will take away from your selection.
Now, if you were to select inverse, and get rid of the background, you would notice how jagged the edges of the car became. This is where the Refine Edge comes in handy. In order to open up the Refine Edge toolbox, you need to right click your selection and then scroll down to the Refine Edge selection. The tool box will open and allow you to change the parameters of your selction, everything from smoothing, feathering, and increasing or decreasing the selection size. If you have CS5 you will also be able to use the Edge Detection to make a more precise selection, but that is a little too complicated for this basic Instructable.
Note: I only selected this to show you the advantages of this tool, I did NOT do anything with this selection.
However... thinking back on it, you can get the general selection of your car, create a new layer, select the new blank layer, right click your selection, and choose to fill with color in order to speed up the next step. I will go into how to create a new layer in the next step if you do not know how to already, in addition to the Brush (B) and Erase (E) Tools.
Step 4: Tool: Crop Tool (C)
For example, the picture below shows the Crop (C) with a 1000 px by 1000 px. To get this setting, simply do what I demonstrated in a previous step with the Rectangular Marquee Tool (M). Notice, the Crop (C) doesn't take up the entire screen even though the canvas itself is 1000x1000 px. The reason for this is because the 1000x1000 is the finished resolution, as well as the ratio that the Crop (C) must follow when selecting.
You may also notice the lines that are going through my Crop (C) selection. These are the Rule of Thirds perspective lines. Basically, it is a photography guideline. The focus points of the image are where the horizontal and vertical lines meet, so if this was a face, you would want the eyes to meet where the horizontal and vertical lines meet. More about the Rule of Thirds is here.
Step 5: Tool: Brush Tool (B)
But before we get too crazy with the paint, you will need to create a new layer, on top of the layer with the car. To do this, you need to click the button on the bottom of the layers tab that looks like a peeling Post-It-Note. if this layer isn't on the top of the layer list, simply click and drag it up to the top of the list. Now you want to change the opacity to around 50% in order to see the car under the new layer. Make sure you have Layer 2 selected before changing the opacity.
Now you can begin to paint over the car with any color you want. I chose red because it is highly visible. The color doesn't matter because we will be using some Photoshop magic in the next few steps. Notice that I only changed the opacity after I got the general outline of the car. It doesn't matter when you change the opacity. Once you have completely covered the car in a coat of red paint, it is time to fine tune your paint job with the Erase Tool (E)
Step 6: Tool: Erase Tool (E) & Zoom (Z)
The Zoom Tool (Z) is quite simple, it allows you to zoom in on your picture. Once you select the tool, either click on the (+) or (-) on the top of the toolbar. OR you can do it the easy way by just clicking and dragging to the right to zoom in, or clicking and dragging to the left to zoom out.
To navigate when you are zoomed in, you can either use the blue scroll bars, or use the Hand Tool (H) to drag the picture around as you are zoomed in. The Hand Tool isn't special enough to have its name in the title of this step... luckily it is a hand and not a wrist... yeah bad joke, moving on...
Make sure to erase all of the red from parts of the car that are not painted. This includes windows, car interior, vents (if they don't have the paint on them), trim, lights, and the grille. You should end up with something similar to the 4th picture.
Step 7: Blending Options
You can arrive at the Blending menu two ways.
1) Right click the layer you want to blend and select the Blending Options... to open up the menu
2) Double click the layer. Double click the right side of the layer because if you click the layer name, you will get the option to rename the layer instead of opening the Blending options.
Once you do either one of these steps, the menu shown in the 2nd picture will pop up. It looks a little confusing at first, but all you really need to see is the "Blend Mode" and it's opacity slider, and the "Fill Opacity" right below it in the Advanced Blending portion.
What you are going to do is change the color of the layer, to do this, change the "Fill Opacity" in the Advanced Blending portion of the menu to 0%. After doing this, your layer is still at 100% opacity, but you can no longer see the red. To add a color overlay, select the "Color Overlay" on the left side of the menu. A screen similar to the 4th picture should pop up. Now what you need to do is change the "Blend Mode" to the option of Overlay. Once you have done that, you should change the color of the overlay by clicking on the color box to the right of the "Blend Mode".
-Tip- You will need to select a darker color than you may expect due to how the Overlay mode works. The green color that I chose is nearly black, but the car shows up as a light green.
Step 8: Using the Curves Option
To get to the Curves tool, you will need to go into Image>Adjustments>Curves
The basics of Curves-
Curves allows you to change how dark or bright an image is. This isn't just contrast changes here. You will notice that there is a funky looking graph with a diagonal line going from the bottom left to the top right. The X-Axis of this graph is the darkest colors on the left, and the brightest colors on the right. If you drag the diagonal line down near the bottom left, it will darken the dark colors. If you drag the diagonal down on the right, it will darken the lighter colors. This also works for brightining up the dark colors and light colors when you pull the diagonal up.
The Curves tool is a professional photographers FAVORITE tool. They usually employ an S curve (shown in picture 3)) This will result in a picture that really pops out. You can see the difference in the 4th picture. Keep in mind the 4th picture is NOT MINE, I do not endorse the product, nor do I endorse the website. I am simply showing you the before and after for comparison.
Step 9: The End Result... or Is It?
Well... maybe not a pro, but you are better than when you started. Now that you know the basics of Photoshop, go out and mess around with all of the options in the Blending Options, mess around with the many pre-loaded filters Photoshop offers. Experiment with changing the colors of people's hair, their eyes, the color of houses, the color of dogs, and maybe even branch out and try your hand at more complex tutorials online.
Remember, you have to practice Photoshop in order to become better at it. If you have a suggestion for a future Instructable Photoshop Tutorial, Questions about tools that I haven't covered, corrections, or comments, feel free to post on this Instructable. If this Instructable has helped you in any way, feel free to tell me about it.
I plan on adding more tools to this Instructable at a later time, but considering I did both the Photoshop and the Instructable write up all in one go, I'm a little tired. Future Tools to be added: Crop, Burn, Dodge, Type, possibly the Pen Tool, and Transform Tool. Feel free to suggest any other tools that may be helpful for me to go over.
