“Resizing”

When we take a photo with our digital camera, the picture quality is exceptional in terms of dimensions and size (in MB) which are of acceptable standards.

For example if you have a favourite photo that you want to place on the Internet, then you must make sure that the dimensions of this picture are not too large and especially that the number of MBs of this picture is not too high. The more megabytes, the longer you have to wait before you get to see something on the Internet.

If the size of the picture is big it takes lot of time to upload

 

If the pictures are too big and too heavy to e-mail, you need to first change the format.

To resize a photo, open it in “PSP”.
The photo can be opened by selecting “Open” in “File” tab of the menu bar or by clicking the “Open” button in the standard toolbar.

In the above two cases, you can navigate to the folder where the photo is located, select the photo and click the “Open” button in the dialog box.

Once the photo opens, click the “Image” option in the menu bar and select “Resize” in the drop-down menu.

This opens the “Resize” dialog box:

On the left side we find the “Original” size and resolution.
On the right side we find the “New” dimensions and resolution.

When you change the width or height under the “Print Size” column in the “New” section, then automatically the “Width” and “Height” in the “Pixel Dimensions” will be adjusted.

This has nothing to do with the width / height ratio of the picture, but just the fact that an image is composed of pixels.  If you reduce the size of a picture then pixels are removed from the picture and vice-versa.

The “Pixel Dimensions” varies by varying the “Resolution” in “Print Size”.  The default setting for “Resolution” is pixels/inch.

The standard dimension of the image is 72 pixels per inch.

This is an excellent ratio which can be used while placing a photo on the internet.
If you print a photo you must ensure the Pixel / inch ratio should be at least 350 dpi. Confirm the “Resolution” before you take the printout on your printer.

 

As mentioned earlier, the size and the pixel dimensions has nothing to do with the locking of the height / width ratio.

Select the check box, “Advanced Settings”, and then select “Lock Aspect Ratio”.
By default this is checked, and if this is not the case you now know where you need to set this up.

If you wish to change the size, height / width independently, de-select this checkbox by clicking it again.

 

If you wish to change the size of the image without changing the size of the pixels, for example, to print your photos, then uncheck the box for the text, “Resolution” in “New”.

 

Remember, in this part of the lesson that unless you select “Resolution” in “New”, you can not add or remove pixels from the picture.

 

Rotating photos

When we take a picture with the camera in a rotated position, then we must rotate the photo in “PSP” to view it in a normal way.
For this we have a number of options.
One option is to click on “Image” in the menubar and click on the “Rotate Left” or “Rotate Right” options. In both cases, this image will be the rotated through 90°.
If you want to rotate the image in a different dimension then click the “Image” button in the menu bar and select “Free Rotate” from the drop-down menu.
This opens the “Free Rotate” dialog box where you have the option to rotate the image at a certain angle (90 °, 180 °, 270 °) to the left or right, or you can enter the a rotation angle in the “Free” textbox.
Obviously you can determine the direction in which you want to rotate this.

 

Other ways to rotate an image are using the options “Mirror” and “Flip”.

In the “Mirror”option, the image will rotate about its horizontal axis. In the “Flip”option, the image will rotate about its vertical axis.

Both these options can be found under “Image” in the menu bar.
