Digital image editing enables one to modify an image or photograph as per your requirements. It is often used to enhance the clarity or alter the size of an image. Cropping and resizing are the popular image editing operations. But there are several other editing functions and it is always helpful for you to know them as a photographer.
1. Image Resizing
You can resize the image through this image editing process. It is also known as image scaling. The cameras which have high resolution produce the images in large size.
Most space is required for large size images and you cannot place those large size images in the internet. So, to avoid this situation, image scaling has been introduced. Through this process, you can scale the image into the required size.
2. Image Cropping
You can crop the extras present in the image through image cropping. It is a simple technique. You can improve the composition of the image and clarity levels through this technique.
This histogram plots the total number of pixels present in the picture (in vertical axis) with certain brightness values (in horizontal axis).
4. Noise Removal
Image editor features several algorithms to remove or to add the noise. Through these algorithms, you can remove the scratches and dust present in the image.
Removing the unwanted elements present in the image: Using a tool named “clone” you can remove the unwanted elements present in the image. The overall composition of the image will also be improved through this image editing process.
5. Color Change
You can change the colors present in the image through image editors which have color swapping abilities.
6. Image orientation
You can alter or rotate the image in any degree or in any direction through image editors. Don’t forget to crop the images after rotating or altering them.
7. Perspective Distortion and Correction
You can transform or distort the shape of the image through some image editors. You have to perform this task with appropriate care because the image will be reprocessed through interpolation of the pixels which are presented adjacent to them.
8. Image Softening and Sharpening
Graphic programs will be used to soften and sharpen the image. Edge enhancement is the technique which is used to sharp the images.
9. Merging of Images
Several graphic applications provide the facility to merge two images into a single one. While performing, you must control the placement and orientation of each image.
10. Image Slicing
It is the recent tool introduced in digital image editing software. Through this software you can slice, label and save the image separately from the whole image.
11. Special Effects
You can create lots of unusual special effects for your image through image editing software. You can skew and distort the image into several ways through this method.
12. Brightening and Contrast
You can add required brightness and contrast to your image through the image editing software.
13. Changing Image Color in Depth
Through software, you can change the color of the image in depth. It is a special process which should be performed with special techniques.
14. Color Adjustments
You can adjust the colors present in the images through several varieties of techniques. Maintain balance of colors while adjusting the image to obtain more natural look.
15. Print Quality and Size
You can print the image perfectly by controlling the quality and print size of the digital image.
Pixels-per inch (PPI) variable is the special variable which will be stored in the image. So, before printing the image you have to control this pixel-per inch variable to attain best output.
