GIMP. ACTIVITY 1 CHANGE OF LOOK


In this activity we will retouch a photo of a person changing the color of his/her eyes, hair and lips. We will also try to improve his/her appearance by cleaning up pores, wrinkles and other imperfections. We will need a person's front picture similar to the one shown below. The picture must show the face at the foreground (en primer plano), the hair and the top of its clothes in the better possible quality.


In the pictures below you can see a sample of the starting point and the expected result.

HOW TO MAKE THE PICTURE

FRONTAL PICTURE

 

Some examples of pictures that will and won't work

 

DISHEVELED HAIR IS A PROBLEM,

 


The main problem in this picture is the hair. There are too many scatterd locks of hair. It will be very difficult ro paint a color over them in a convincing way without missing many of the thinest locks hither and yon .

Another weak point is the framing. Our point of interest must be the face, since we are going to retouch lips, eyes and the face skin so we need a more close-up image, where the face is more in the foreground




Here Penelope's hair is carefully combed, it will be easier to paint it. It would be even better if her tail fell hidden on her back though

The framing is almost better since shows a better close-up of the face.

 

 

LET FALL THE LONG HAIR ON THE BACK

 





You will save a lot of work if the long hair falls back your shoulders, and not on your chest

 

CLOSE-UP PHOTOGRAPHY (primer plano). FRAMING MUST FOCUS ON THE FACE .

 


This picture has an almost perfect framing, because it is a close-up of the actors face where all the tiny details are visible. The only objection Is that most of the cloths have been cut off. We need to see part of the shirt in order to change its color




This picture will be very difficult to retouch. You will need to zoom in a lot to upscale the face so that you can work it, and unless you shot the picture using a high resolution camera, you'll have all the details on the face blurred.

Another problem is the background scenario. To save time you must keep the background simple, a wall in a plane color will be perfect.

 

 

 

SECOND SNAPSHOT. SEMI-PROFILE PICTURE



In this second picture we need a semi-profile picture. This means the model must stare in a 45º angle to the camera. There must be possible to see both eyes and the nose. In the following table is shown an example of the required picture

 



In these images below are shown the starting point and the expected result. As you can see the goal of the activity is to make a 3D effect in which the face seems to be getting out from the frame. That's the reason why we need a 45º to 60º semi-profile shot, in which the perspective of the face will be similar to the one of the frame.

 








GIMP. ACTIVITY 1 CHANGE OF LOOK


 





 









In the table of images below are shown three different merging modes



 

Modo blanquear

combinado granulado

 Modo tono

 






Look at the table of images below. On the left picture you can see the iris color chosen, and on the right the color achieved using the tone merging mode

 


If your eyes are dark black the result will be disappointing. Look at the next couple of pictures. We have applied the blue eyes procedure to the baby's eyes to no effect, because the baby has very dark black eyes. The aforementioned merging procedure only works if there are intermediate tones of color to merge with. It can happen something very similar if your eyes are very light gray.


Save your work. Save a back up copy with other name.

For these cases, (and actually most of you will have dark black and brown eyes), we will try a different solution called iris transplant.

IRIS TRANSPLANT

 

This procedure can be used when the aforesaid fails, because the person's eyes are too dark or too light. Before proceeding, make sure you have already saved a backup copy of your GIMP project with other name. Save this project as borrowed iris.

 

Download the two images of an iris shown below, using the option guardar imagen como from the contextual menu. You can chose any of them. The quality of both images is good enough. But they have some flaws. The first one have excellent mid-tones which will turn in a great blue or green iris. But the pupil is a bit too dilated and the person might look sort of high.

 


This other below is also excellent, whith a more convincing pupil. But the amber tone here is too light, and to get blue or green colors will be more difficult

 




    








   


EXERCISE 2. CHANGE OF COLOR OF LIPS AND CLOTHS


In this activity the girls will change their lips color. It might be unseemly that boys change their lips color so they will change the color of their clouths instead, (shirt, t-shirt, jersey visible in the image).







Te result must look similar to the image shown below. The quality of the result will mainly depend on your accuracy match the borders of the eyes, lips and cloths. Save the file and out of security make a back up copy with a different name.



EXERCISE 3. CHANGE THE HAIR COLOR



      





 



Save the file and out of security make a back up copy with a different name.



EXERCISE 4 OVERHOUL FACE ERASING LITTLE FLAWS, SHINES AND IMPERFECTIONS












Now click on the white shinning area. A little circle cloned from the previously clicked area will be copied there covering the shinning white area with the correct skin color. Repeat, adding more cloned circles until getting rid of the shinning area.




 

The quality of the final result will depend on how carefully and how patiently you use the blurring tool. Look at the left side of the face in the picture below. The blurring has been made here patiently using short strikes and repeating the process many times. On the contrary in the right image the tool has been used quicker, using long strokes , with a big size paint, resulting in a smudget texture, as if the model had got her make up smeared.



                   



Original.

Actually the person in the picture hadn't many flaws to retouch, but notice how in this picture there are no longer shinnings


            Save the file, make sure that all is correct and you have finished it. Send the gimp file by email tot Informatica.ieselcabanyal@gmail.com
