Working in the field of altering pictures by making them more beautiful and changing the appearance
Question

                It is well known that there are many doubts about photography. I would like to know what is the ruling on altering pictures by using Photoshop; this program can make a person look more beautiful and alter some of the features, and it has caused fitnah because some girls come and ask for their eye colour to be changed, or for their eyebrows to be thinned, or for blemishes to be erased from the face, or for the hairstyle to be changed. 

I would like you to explain the ruling on these actions, and I would like complete details of the source of the fatwa so that I may explain to some people with full evidence and proof.
Praise be to Allah.Firstly: 
Contemporary 
    scholars have differed with regard to the ruling on photography. In the 
    answers to questions no. 10668 
    and 12786 we have stated that 
    the more correct view is that it is haraam. 
Secondly: 
Some 
    scholars who are of the view that it is permissible and not haraam have 
    stipulated conditions for that: 

    1-That the purpose of the picture 
    should be permissible, such as for a passport, driver’s licence and so on.

    2-The photographer should not 
    introduce any changes or improvements to the picture.

    3-It should not be a haraam 
    picture such as a picture of a woman in makeup and the like.
It is clear 
    that these conditions are not met in the case mentioned in the question. 
    Thus it is clear that the action asked about here is haraam. 
Shaykh Ibn 
    ‘Uthaymeen (may Allaah have mercy on him) said: 
With regard 
    to these cameras which produce an image instantly, and the person has 
    nothing to do with this image, we think that this does not come under the 
    heading of image-making, rather it comes under the heading of transmitting 
    an image that Allaah has made by means of this machine. This is like a 
    reflection and the person has nothing to do with making the image. The 
    ahaadeeth speak rather of image-making that is done by people in imitation 
    of the creation of Allaah. This is like when a person writes a letter and 
    makes a photocopy of it. The image that comes out is not what was done by 
    the one who operated the machine; perhaps the one who operates the machine 
    does not even know how to write. People will know that this was written by 
    the first person, and that the second person had nothing to do with it. But 
    if he makes this photographic image for a haraam purpose, then it is haraam 
    because the means that lead to haraam ends are also haraam. End quote.
