Perspective

Sometimes it so happens that when you take a picture without having direct access then the picture recedes into the background. For example the photo taken below is in a museum and you can see that the picture recedes into the background.

If we have to straighten this picture or the object in this picture so that we get a nice front view, we use the  “Perspective correction” option.
Click the arrow pointing downwards next to the “Straighten” option in the toolbar, and select “Perspective Correction”.
This places a marquee on the image which you can click and drag on the four corners of the object to get a front view.
Select the “Crop Image” option in the options bar.
When all four corners of the bounding box are perfectly aligned, click the “Apply” button in the options bar.

 

“Red eyes”

We can remove red eyes with the “Red Eye” option as you all know.

For those who do not know, the first thing you have to do is to zoom into the image and then select the “Red Eye” tool in the tool bar and finally click the red eye.

A better way to understand “Red Eye” is to use the “Red Eye Removal” dialog.
Click the “Adjust” button in the menu bar and select “Red Eye Removal” in the drop-down menu.

This opens the “Red Eye Removal” dialog.
At the top of the dialog we have the “Preview on Image” checkbox. When this is selected you will see the results displayed next to the picture, in the dialog.

 

Below this, we have two preview windows, “Before” and “After”.
The buttons below the preview windows are used to zoom into the image.
By clicking on the “Pan” option (1) we can immediately place “Red-eye frame” in the correct position.
You can always move in the preview window, “Before” by clicking and dragging, and the size of this small box can be changed by dragging the blocks at the edges of the frame.
In the preview window, “After”, you see the result.

 

Below the zoom tools, we find a textbox with a drop-down arrow (2).
If you click it, you have a list of preset options to edit red eyes.
If you wish to have your own list of preset options and to save them, or add them to the list, click the button, “Save Preset” (3).
If you wish to use the default settings of the “PSP”, click the “Reset to Defaults” button (4).

 

Below that we have the “Method” drop down box.

In the “Method” drop down box, we have several options.
The first option, “Auto human eye”, is to remove the red eye in a human.
The second option, “Auto animal eye”, is to remove the red eye in an animal.
You can use to remove the red eye from a photo of your cat.

Cats do not have a circular pupil, but a more oval pupil.  When you have selected this option you can change the width of the frame without changing the height of the frame and move it.

This can not be used for the option, “Auto human eye.”

 

The third option “Freehand Pupil Outline” is used to drag the mouse around the edge of the red area of the pupil until you reach the beginning point of the selection.
The fourth option “Point-to-Point Pupil Outline” is used to drag the mouse around the edge of the red area of the pupil and double-click it until you reach the beginning point.

Clicking on the OK button removes the “Red-eye frame” and all your settings with it.

 

It does take more time to remove a red eye this way, but the results are better.
