About myself
There are many people who are living in this world and everyone has different personalities. There are no two people who have the exactly same personalities. Everyone in this world is unique in their own ways. One’s personality is something that does not change which makes one unique and special. As for me, I am a responsible and sympathetic person, however, I am a self-centered person as well who may have made enemies with a lot of people anyway my name is LIM WEE JIEH.
I am a pretty responsible person and I do what I am supposed to do. As now, I am a student in school, therefore I do my homework every single day and study for what I have learned at home. I also pay attention in class most of the time as well. Besides that, I organize my work as well. At home, I am a child, so I respect my parents and help them to do house works, such as doing laundries and washing dishes. I clean my room once a week as well because that is my responsibility as being a child. I also help out friends and classmates when they need help. I give out advices and suggestions to them when they need support and help as well. Generally, I can say that I am a responsible person who does my duties.
Besides being a responsible person, I am also a person who is sympathetic. I have been a sympathetic person when I was really young. For example, when I walk on the street and saw some handicapped people or vagrants, I would help them by giving them money or whatever things that I can do for them to have a better living. When I see animals without a home, I feel sorry for them and I might buy some food for them to eat. I used to donate money to the charities for orphans with my family as well. I feel sympathetic to many people in the world and therefore I do something to help them have a better living.

In addition, the Photoshop CC Image Size dialog box has been updated for ease of use:
- A window displays the preview image from the resizing parameters.
- Resizing the dialog box resizes the preview window.
- The Scale Styles option is turned on and off from inside the gear menu in the upper right corner of the dialog box.
- From the Dimensions pop-up menu, choose different units of measurement to display the dimensions of the final output.
- Click the link icon to toggle the Constrain Proportions option on and off.

Resizing images
- Choose Image > Image Size.
- Do any of the following to modify the image preview:
- To change the size of the preview window, drag a corner of the Image Size dialog box and resize it.
- To view a different area of the image, drag within the preview.
- To change the preview magnification, Ctrl-click (Windows) or Command-click (Mac OS) in the preview image to increase magnification. Alt-click (Windows) or Option-click (Mac OS) to reduce the magnification. After clicking, the percentage of magnification briefly appears near the bottom of the preview image.
- To change the unit of measurement for the pixel dimension, click the triangle next toDimensions and choose from the menu.
- To maintain the original ratio of width to height measurement, make sure that the Constrain Proportions option is enabled. If you want to scale the width and height independently of each other, click the Constrain Proportions icon to unlink them.Note:You can change the unit of measurement for width and height by choosing from the menus to the right of the Width and Height text boxes.
- Do any of the following:
- To change the image size or resolution and allow the total number of pixels to adjust proportionately, make sure that Resample is selected, and if necessary, choose an interpolation method from the Resample menu.
- To change the image size or resolution without changing the total number of pixels in the image, deselect Resample.
- (Optional) From the Fit To menu:
- Choose a preset to resize the image.
- Choose Auto Resolution to resize the image for a specific printing output. In the Auto Resolution dialog box, specify the Screen value and select a Quality. You can change the unit of measurement by choosing from the menu to the right of the Screen text box.
- Enter values for Width and Height. To enter values in a different unit of measurement, choose from the menus next to the Width and Height text boxes.The new image file size appears at the top of the Image Size dialog box, with the old file size in parentheses.
- To change the Resolution, enter a new value. (Optional) You can also choose a different unit of measurement.
- If your image has layers with styles applied to them, select Scale Styles from the gear icon to scale the effects in the resized image. This option is available only if you selected the Constrain Proportions option.
- When you finish setting options, click OK.
To restore the initial values displayed in the Image Size dialog box, either choose Original Size from the Fit To menu, or hold down Alt (Windows) or Option (Mac OS), and click Reset.
Automatic
Photoshop chooses the resampling method based on the document type and whether the document is scaling up or down.
Preserve Details (enlargement)
When this method is chosen, a Noise reduction slider becomes available for smoothing out noise as you upscale the image.
Bicubic Smoother (enlargement)
A good method for enlarging images based on Bicubic interpolation but designed to produce smoother results.
Bicubic Sharper (reduction)
A good method for reducing the size of an image based on Bicubic interpolation with enhanced sharpening. This method maintains the detail in a resampled image. If Bicubic Sharper oversharpens some areas of an image, try using Bicubic.
Bicubic (smoother gradients)
A slower but more precise method based on an examination of the values of surrounding pixels. Using more complex calculations, Bicubic produces smoother tonal gradations than Nearest Neighbor or Bilinear.
Nearest Neighbor (hard edges)
A fast but less precise method that replicates the pixels in an image. This method preserves hard edges and produces a smaller file in illustrations containing edges that are not anti-aliased. However, this method can produce jagged effects, which become apparent when you distort or scale an image or perform multiple manipulations on a selection.
Bilinear
A method that adds pixels by averaging the color values of surrounding pixels. It produces medium-quality results.

How to Remove Background With Photoshop Elements
One of the most useful skills you can learn in Photoshop is removing the background from an image. This will allow you to stick the subject in any picture that you want, without having to worry about blending backgrounds, or dealing with large expanses of plain white. There are a couple of ways to remove the background of an image, depending on how complex that background is.
Method 1 of 2: Deleting a Simple Background
-
Edit step1Open the image in Photoshop Elements. This method works best if the background is a solid color, or close to a solid color.Ad
-
2Navigate to the Layers window. This is typically located on the right side of the screen. Most images that haven’t been edited before will only have one layer, called “Background”. Right-click on this layer and select “Layer From Background…”.
- This will open the New Layer window. Leave the options at their presets and press OK. “Background” will change to “Layer 0”. Doing this will unlock the image, allowing you to edit it.
-
3Select the Magic Eraser tool. This is located in the Eraser tool menu. To access it, click and hold the Eraser tool icon. Select the Magic Eraser Tool from the menu that appears.
-
4Adjust the Magic Eraser settings. Once you select the Magic Eraser, you will see some settings in the top menu bar. Adjust them so that they look similar to this:
- Set Tolerance to 20-30. A low tolerance will keep parts of your original image from being erased when you use the tool. Adjust the tolerance to find a level that works for your project.
- Check the Anti-alias box.
- Check the Contiguous box.
- Set Opacity to 100%
-
5Click the background. The Magic Eraser will remove all of the color that you clicked on, turning it into transparent background. The Tolerance level will affect how many related colors are removed as well (For gradient backgrounds).
-
6Make any minor adjustments. If you were deleting a solid-color background, it should be almost completely erased in one click. You may need to zoom in and make minor adjustments with the Eraser tool.
-
7Select your object. Once you are satisfied with the removal of the background, you can use the Lasso tool to draw a rough outline around the object. Press Ctrl+Shift+J to create a “New Layer Via Cut”, which will place your object on a separate layer from the old background. You can now delete the background layer (Layer 0).
-
8Save your image. You now have an object with a transparent background that can be overlaid onto any other existing image.Ad
Method 2 of 2: Erasing a Complex Background
-
1Open the image that you want to edit. This method will allow you to delete more complex background without removing the subject of the picture..
-
2Select the Background Eraser tool. Click and hold the Eraser icon until the Eraser menu appears. Select Background Eraser Tool.
-
3Set your brush options. In the toolbar at the top of the window, click the arrow icon next to the brush shape. Set the Hardness to 100% so that the edges of the brush remove as much as the center. Set the diameter to a size that works well with the image you have. You will be making large, broad strokes with the brush.
-
4Set the Limits to Contiguous. This will delete the color that you select in the circle, but only if the colors are touching. This will help keep from deleting colors inside the subject of the photo, while only erasing the background.
- If you have spots of the image where there is background inside the subject (wisps of hair that can be seen through, for example), use the Dis contiguous option to remove the background from inside the isolated spots.
-
5Set a low Tolerance. A low tolerance limits erasure to areas that are very similar to the sampled color. A high tolerance erases a broader range of colors. Set your tolerance between 20-30.
-
6Bring the pointer near to the edge of subject. You will see a circle with small cross hairs in the center. The crosshairs show the “hotspot” and deletes that color wherever it appears inside the brush. It also performs color extraction at the edges of any foreground objects, so that color halos are not visible if the foreground object is later pasted into another image.
-
7Click and drag to start erasing. You can allow the circle to cross over into the subject while erasing and you shouldn’t lose anything, but do not allow the cross hair in the circle to touch the subject, otherwise you will start deleting those colors..
-
8Check your progress. As you click and drag you’ll see the checkerboard pattern appear in the areas you have erased. The checkerboard represents transparency.
-
9Continue erasing around the subject. In some places you will need to reduce the size of the brush to ensure that you don’t accidentally erase part of the subject. For example, in this image you would want to change the size when erasing between the petals.
-
10Focus on erasing on the exact edge of the subject. Once you have the subject properly outlined, you can make broad strokes with a standard eraser to remove the remaining background.
-
11Smudge the edges. If you want to soften the edges of your subject so that it will blend in better with the whatever background you put it on, use the Smudge tool. Set it to a low strength (20% or so) and drag it around the edge of the subject. This will soften any hard lines.[1]
