“Object Remover”

Another way to delete an object in your photo is by using the option, “Delete Object”.
We can also use “Clone” tool.
The first thing you have to do is to select the portion that needs to be replaced.
Click the button, “Selection Mode” in the options bar, click and drag on the portion of the photo you want deleted.
Then click the “Source mode” button in the options bar and select the portion of the picture that you want to replace.
This places a marquee in the photo.
You adjust the size of the marquee by clicking on the blocks at the edge of the selection frame by clicking and dragging.
Move the selection frame by moving your mouse pointer over it, and when it changes into a four-headed arrow, click and drag it to the correct position.
Finally, click the “Apply” button.

We have the options “Coverage” and “Feather”.”Coverage” will determine the coverage, or in other words the transparency and “Feather” will smoothen hard edges.

 

“Background Removal”

If you have an image on a website, it can sometimes suit the main subject in the image to be isolated by removing the background.
You can do this by using the “Background Eraser” tool option in toolbar.
When you work with the default settings you can delete the background of a photo by using the brush on the background while you move keeping the left mouse button pressed. All pixels which correspond to the pixel in the center of the brush need to be erased.

 

A word of explanation about the options:

“Cover”: When this is set to 100%, pixels are completely erased to make them transparent. A lower opacity erases pixels that are partially transparent.

“Tolerance”: This determines how closely the selected pixels must match with the sample pixel. The sample pixel is the pixel over which the tip of the pencil is located.
At lower values, only pixels with closely matching colors are erased.
At higher settings, more pixels will be deleted. The value ranges from 0 to 512.
This option is not available if the Enable Automatic tolerance option is selected.

“Sharpness”:This determines the rate of the softness of the deleted edge depending on the color difference between the object and the background.

You can use lower settings when the edges that you are erasing form a gradient (a more gradual color transition); you can use higher settings when the edges that you are erasing have a more abrupt color transition.

The range of values are from 0 to 100.

“Sampling”: Indicates the basis on which pixels are erased and provides the following options:

“Once”: It samples the point where you first click and then erases all matching pixels for the duration of the stroke. This setting will erase similar colors and continue to maintain your desired areas.

“Continuous”: It continuously take samples and erases all pixels that match. If the area to erase is variable, you can use this option and set the Step value low, so that the area is sampled frequently as you erase. The tool can erase any color it encounters, including foreground colors if the sampled pixel falls in the foreground area.

“Background Language”: It erases all pixels that match the current background color on the Materials palette.

“Foreground Language”: It erases all pixels that match the current foreground color on the Materials palette.

“Limits”: Allows you to specify whether the erased pixels are adjacent and offers the following options:

“Non-contiguous”: It erases all pixels in the tools path that match the sampled pixels, even if they are non-adjacent. You can use this mode to correct areas in which the background is displayed because of holes in the image.

“Contiguous”: It erases only contiguous pixels that match sampled pixels. You can use this mode when the background pixels are of a color that is similar to that of the edges of the object you want to isolate.

“Edge Search”: It uses the edge information to restrict the erasing.

“Automatic tolerance“: It determines the tolerance based on the pixels in the tools path. The tolerance may change continuously as the tool moves over different parts of the layer. You can unmark this check box to specify a Tolerance setting.

“All Layers”: It samples data from all layers merged together. Only pixels in the current layer will be erased.To sample data from the current layer only, you can unmark the respective check box.

“Ignore Brightness”: It ignores sharp differences in color lightness and saturation. You can select this check box when the colors in the object that you want to isolate are strongly saturated and the background is unsaturated, or vice versa.

 

If you want to use this picture as a transparent image on the Internet, save them it as transparent POISON.
