Question

You need to apply multiple photoshop techniques on an image.
The following techniques to be applied:
Image retouching
Image stretching and equify technique
Changing background (white)
The above techniques need to be applied to an image with a person.
You can have as many layers as you need but keep the original image layer at bottom so that it can be compared with the edited image.

Answer 1

Image retouching:

This technique can be considered as a more subtle approach to local image edits. One could say that, things which the photographer could realistically have done in preparation of taking the picture. E.g. removing distracting elements, applying or looking for a bit different lighting, preventing unnecessary inelegant shapes or even technical flaws. By utilizing the image retouching technique users can apply changed over an image done without conveying different perceptions.

Image stretching:

The sensitivity of this technique depends on several factors including the amount of distortion, the content of the image, and the viewer’s cultural background. Extending the technique explores the category of images to which people are most sensitive. On images with people in them, viewers can see moderately small stretches even with brief exposures to the images.

Image equify:

This photoshop technique works on enhancing the reflectance layer by ignoring illumination, which is mist preferred filtering technique. Fuzzy based image enhancement approach makes use of illumination by omitting reflectance. Homomorphic decomposition is used for getting the exact illumination image from the value layer of ‘Hue’, ‘Saturation’, and ‘Value’ (HSV) final image.

Changing background:

This photoshop technique is based on the concept of semantic segmentation. It is the process of linking each pixel in an image to a class label, classifying its different parts such as the ones belonging to the person and the others of the background behind him. As a result of this process, different parts of an image can be separated from each other and the background behind a person can be blurred, removed, or simply replaced with an image or a video as per requirement. Here I have replaced it with a simple white color.

Expected output on the image:
