Adding People

Adding People To Pictures
Now you can touch up your photos, which is an extremely useful skill with this next lesson.


How often have you been with a group of people...family, friends, school classes... and there is that one person who conveniently disappears right before the picture was taken, and reappears right after the image has been taken?
Chances are, pretty often.


In those cases, you would usually try to retake the picture, but now you don’t have to. All you need is the image that is missing one person, and a picture of the person who disappeared.


The first step is to open both the group picture, and a picture of the missing person into Photoshop. For this tutorial, I will be using a class picture, shown below and the student who was absent the day it was taken, also shown below..


Once the images are opened in Photoshop, go onto the one that has the single person in it. You are going to select the lasso tool, shown below, and select around the person, shown under the lasso tool. (Note: When using the lasso, you cannot click around the object and must hold and drag around the object.)
Once you have selected around him, you should see what is referred to as ‘Marching Ants’, which is the dashed line that shows around your selection. After selecting him, copy and paste him into the image of the entire class.
After he is inserted into the entire class image, you need to lower the opacity until you can see both the single person and the entire class behind him.
To set the opacity, go the right toolbar and look for the word opacity next to 100%.
After you have set the opacity to be able to see both the entire class and the single person you need to line him up so that he looks as if he was there originally.
The next thing you need to do is enable a layer mask to remove the remaining background surrounding the person. To enable a layer mask, go to the side panel and select the icon that shows a circle inside of a rectangle, shown below.
Once the layer mask has been enabled, select the paintbrush and ensure that the color is white before you begin to paint because if you don’t, the image that is currently there, may erase itself. With the layer mask enabled, paint around the background of the person. until you are happy with the result.
Once the single person is where you want and the background has been erased enough that he looks as if he belongs in the image, all that is left to do is to touch up both photos so that it looks as if it was one image.
In the image above, the kid in black looks as if he was there the entire time, and if you had not already learned that he was missing, you probably wouldn't be able to tell.

Now that you can add people to images, what happens when there is that one person who walks into the background right as the picture is taken? Well, that will be the next lesson.

Touch Ups

Photo Touch Ups
Now you are able to use the tools in Photoshop and know where to find them. Maybe now you want to know how to use Photoshop to improve your pictures? I hope so, because that is the next lesson.
Why?
The reason is that even if you can do manipulations in Photoshop, you need to know how to touch up your pictures to make them look better.
Touch ups include;
  • Resizing to appropriate size
  • Fixing the resolution (DPI)
  • Adjusting the brightness and contrast levels
  • Burning or dodging the picture if necessary
  • And lastly, Cropping the image.


The first thing that you are going to do is open the image in Photoshop. Once you do, your screen should look similar to the one below.


Resizing
The reason that it is important to resize your pictures when you first enter them into Photoshop because if you don’t the picture could become pixelated later on when you print them. To resize the image, go to the Image tab, and go down until you see  Image Size. When you click on it a window should pop up that looks like the one below.
When sizing an image, you often want to use the size 7 1/2 inches by 10 inches for a basic standard. If you know that you need the picture to be a certain size, that would be the size you would want to enter. The width and height depend on the orientation of the image. More often than not, the image will come in at a much larger size than you would think. One example is having a picture go in and be similar or larger than the dimensions shown below.
In this image, the file that was brought into Photoshop was 22.2 inches by 16.67 inches. Most likely, you will not need the picture to be this large and the image may appear to be more pixelated because there are only so many pixels per inch. This leads us into our next touch up.


Resolution
Changing the resolution of an image can help to fix up the pictures. Resolution is usually measured with dots per image, or DPI. The resolution level will depend on what your intended goal for the picture is. If you were going to be keeping the image on a cellphone the resolution would not need to be as high as if you were having the image printed professionally. The closer a viewer is going to be viewing the image, the larger the DPI should be.
Either printing pictures or having them printed: 300 dpi
Posting pictures to an online sight: 72 dpi
An example is shown below. When you originally bring in the image to Photoshop, the dpi will be 180 DPI or lower.
Once you have the resolution set, your next step would be to adjust the brightness and contrast levels of your image.


Brightness & Contrast
Brightness & contrast is another important step when touching up images because it enhances the image. Below is an example. The first image has no changes to brightness & contrast, while the second has been adjusted.
In the first image you see the shell sitting on cement with a building in the background and a car passing behind it. In the second image the contrast was brought up and not the texture of the shell is more apparent and the ground has more texture and there has been a feeling of depth that has been brought in, by increasing the shadows. that are clearly seen. This is a tool that is simple to find. All you have to do is look for the Image menu, and select Adjustments, before selecting Brightness/Contrast, as seen below. The second image shows the window that will pop up once you click on Brightness/Contrast.
Once the window opens, you can move the slider to set both the brightness and contrast to the levels that you think are the best for your image. There is no set level to make the picture better because each picture is different. In some cases you need to use another tool along with the Brightness & Contrast and this is the burn and dodge tool.


Burn/Dodge Tool
When using the burn/dodge tool, it often follows the brightness & contrast tool because changing the brightness & contrast will often expose lighting issues that may have been unnoticed before. A good example is the image used above. When the brightness & contrast was raised, the little bit of color in the sky started to vanish. To correct this issue, simply select the burn or dodge tool from the toolbar. In this case, the burn tool is needed. If you do not see one or the other, click and hold on the one visible until a side menu pops up and then select the tool you want to use. The side menu is shown below.
With some pictures, burning or dodging may not be necessary and can be skipped. When this happens, all that is left is to see if the image needs to be cropped.


Cropping
The last step to touching up an image is to see if there is any cropping that needs to be done. The image that is above is good, but can look better. To crop an image, look on your toolbar for the icon shown below, that resembles two intersecting right angles.
Once you click on this, the screen should change over to what is shown below.
Photoshop will help you with cropping by darkening the area that it will be erasing, so that you know exactly what will be left once the image has been cropped. As you can see above, the original image was a little too close to the center and to close to creating a bullseye image, which is when the object of focus is centered in the middle of the picture. Cropping also removed the majority of the car, which was drawing away from the shell with the bokeh building in the background. (Bokeh is when the background of an image is blurred out instead of in focus.) Once you confirm the crop, the image is done and all that is left is to save the image. When you save the image a window will pop up, similar to the one below
.
More often than not, you will want to save the image at the highest quality, which is 12. Once you hit OK, you are done and have successfully touched up a photograph.


Now that you can do basic touch ups, it is time to begin the manipulations. The next lesson will be on how to add people to images, mainly those people who are not around when the group photo is taken.

Tools In Photoshop

Photoshop CS5 Tools & Features
By now, you know how to compose a good photo. So what?
(http://www.theimediasite.co.uk/unit1_learning_zone_tool_panel.html)
Maybe now that you can compose pictures better, you would like start to learning how to manipulate the images that you have taken. Before you are able to create well done manipulations, you need to know how to use the tools that you will be using to create the manipulations. Below is the toolbar from Photoshop CS5 with all of the extensions that are included. The tools that are circled are the tools that will be most commonly used and they include:
  • Lasso Tool
  • Pen Tool
  • Clone Tool
  • Spot Healing Tool
  • Burn Tool
  • Dodge Tool
  • Magic Eraser Tool

Other tools that will be occasionally used are:
  • Hue & Saturation
  • Free Transform
  • Clipping Mask


Lasso Tool: What is it?
The lasso tool is one of the selection tools available with CS5. When using the lasso tool you begin by selecting the tool and then you select one point around the object you wish to select and continue selecting around the image until you reach the point where you originally started. Depending on the reason you are selecting the image, you may need to refine the edges to remove the small border now around the object. Edge refining will be covered in later on, when needed. You can find it on the toolbar by looking for an image of a lasso, like the one seen below.


Pen Tool: What is it?
The pen tool is another one of the selection tools available with CS5. In some ways this tool is easier to use than the lasso, but your choice of tool depends on what your own preference is.. When using the pen tool you begin by selecting the tool and then much like the lasso tool, you select a point around the object that you would like to start with. and continue to select points around the object until you reach the point that you originally started at. One way that this tool is a bit easier is that it shows each point that you click on. You can find it on the toolbar by looking an image of an old fashioned pen tip, like the one seen below.


Clone Tool: What is it?
The clone tool is very similar to another tool in photoshop, the spot healing tool. The difference is that with the clone tool, you are actually covering an area of an image with another image. This is used more often with markings on clothing or paper, objects within the background that distract from the object and even distracting areas of the scenery. You can find it on the toolbar by looking for an image of a stamp, like the one seen below.


Spot Healing Tool: What is it?
The spot healing brush is very similar to the tool seen above, the clone tool. The major difference is that instead of covering an area of an image with another piece of the image, Photoshop is determining which part of the picture would be best to pull from, but it is also important to remember that this tool is meant to be used on small spots and not a large area of the image. Most often this is used with the touch-up of portrait (removing blemishes). You can find it on the toolbar by looking for an image of a bandaid with an arc of dot above it, like the one seen below.


Burn Tool: What is it?
The burn tool is used when you want to change the lighting in a particular area to add darkness, instead of the entire image. When using the burn tool you begin by selecting the tool, the size of the brush you wish to use (the amount of area that will be covered with one click, and the amount of exposure that the brush has (how dark. you want the amount of area covered with one click). Often it is common to confuse this tool with it’s opposite, the dodge tool. One way to remember the difference is that if you burn something it generally will leave a darkened mark on the object. You can find it on the toolbar by looking an image of a grayish-white hand forming an ‘O’, like the one seen below.


Dodge Tool: What is it?
The dodge tool is used when you want to change the lighting in a particular area to increase the light, instead of the entire image. When using the dodge tool you begin by selecting the tool, the size of the brush you wish to use (the amount of area that will be covered with one click, and the amount of exposure that the brush has (how light. you want the amount of area covered with one click). Often it is common to confuse this tool with it’s opposite, the burn tool. You can find it on the toolbar by looking an image of a ball head pin, or what some might say resembles a lollipop, like the one seen below.


Magic Eraser Tool: What is it?
The magic eraser tool is a tool that can either save you time, or be a time consumer. This tool will erase only pixels that are very similar in color. Most often this is usful if you are trying to remove a background from an object that is a different color than the object. If the tool erases parts of the object then you may need to erase the sections that you do not want included by using the regular eraser first and separating the object from what you are trying to erase. If the magic eraser is still deleting parts of the image that are not supposed to be deleted then you will need to use the regular eraser for the entire thing. You can find it on the toolbar by looking for an image of an eraser with a star shaped burst above it, like the one seen below.


Hue & Saturation:
The hue and saturation tool is often used when you want to change the color of an object, the amount of color vs. black & white within the object, and the lightness or darkness of the object. To access the Hue/Saturation menu, you go to the image menu and go down until you see Adjustments, and then when the Adjustments menu opens, select Hue/Saturation. Another way to select the hue/saturation menu is the hit Ctrl U on a pc, or Cmnd U on a mac. The menu should look like the one below. The box that pops up is also shown below.
Transform:
Transform is used in many ways to distort pictures. The most common form of transform is called free transform and is what is used when you want to re-size or rotate a picture. When free transform is selected, there will be a solid border around each edge (or in a square or rectangle, if the image is not a square or rectangular shape) and there will be small squares at each corner and often in the middle of the edge. The boxes on the corners are how you change the sizes and if you do not hold down the shift key, you will cause the picture to become unproportional. With transform you can also distort and warp your pictures. Distorting your picture is when you stretch the image in all directions or in any direction. Perspective is when you change the perspective of an object. Lastly is warp. Warping an object is when you manipulate the actual shape of the object to include bending the object over itself.
Layer Mask:
Lastly is the layer mask tool.that is important to know how to use. Layer masks are used to hide portions of the an image in a layer. It makes things a lot easier to go back and change mistakes later, than having to redo the entire piece. The first step is to create the layer mask, by locating and hitting the layer mask button located on the bottom of the toolbar that is commonly on the right hand side of the window, shown below in a blue rectangle. When looking at the toolbar, you have to find the button on the bottom of the toolbar that shows a circle inside of a rectangle, highlighted by a blue circle below.
The layer mask is one of the more complex tools, because, odds are that you will not do every step correctly on your first try.
When you first click the button to apply a layer mask, it will seem as if nothing has changed on your picture, but if you look at your layers menu, you will notice that there is now a white box next to the image that you added a layer mask to. If you no longer see the image that the layer mask was added to, that means that the layer was created with black instead of white. Why does it matter?  The reason that it matters is that in Photoshop, the layer mask only recognizes three colors: white, black, and gray. When the layer mask is white, the image will be 100% visible, when the layer mask is black the image will be 100% transparent or invisible, and when the layer mask is a shade of gray it means that the image is not 100% visible or 100% transparent. With gray, the closer to white that you are, the more visible the image will be, compared to when the gray is closer to black and more transparent. To enable the layer mask, you would select the paintbrush tool, shown  below.

Before you begin to use the paintbrush it is important to ensure that the paint color is black because having it white, will add white onto the already existing white, while adding black would in a way, erase the white and the painted part of the image seem to be erased. If you accidentally remove a part of the picture, Don’t Worry. By switching to using white paint, Photoshop will reveal the ‘erased’ portions of the picture. Continue to use the two different colors until you reach the desired look. Another reason that this tool is a lot more helpful is that your edits are never permanent and can always be changed in a layer mask.
