Remove Red Eye
Free Select Tool For Beginners

General Flash Eye Notes
Redeye (green, yellow or blue eye for animals) occurs when a photograph is taken with a flash. Light from the camera’s flash is reflected onto the retina at the back of the eye, and in humans, (and sometimes dogs) results in red eye, caused by the blood vessels. Animals; including, dogs and cats, have special reflective layers (tapetum lucidum), over their retinas - similar to mirrors, and this aids their nocturnal vision. This results in the strange green/yellow/blue eyes often displayed in photographs of indoor pets, (taken with flash). As they age, their eyes become cloudy, exacerbating the spooky appearance caused by flash.

Notes
You can quickly Undo a step at any time by pressing Ctrl then Z. Alternatively, click a previous Undo History snapshot - Windows then Dockable Dialogues then click Undo History. In addition, to Zoom in (or Zoom out) of your image; from the top menu choose View then select a Zoom Tool from the subsequent
drop-down list.

Launch GIMP & Organise Its Workspace & Palettes

1/
Open your choice of Start Image onto GIMP’s workspace - File then Open - Ctrl then O.

Duplicate Your Image
It’s important to preserve your original image: therefore, Duplicate your image; Ctrl then D - (Image then Duplicate). Now, close the original image, and work on the Duplicated image.



Zoom Tip
For accuracy, Zoom into the eyes: - top menu, then View then Zoom.



Shift+Plus Key And Minus Key Tip
To quickly zoom in or out of an image - tap your Keyboard’s Shift+Plus Key or the Minus Key, respectively.



Note
I zoomed in twice.
 


Note
You are looking to isolate both Turquoise Pupils with a Selection Marquee.

2/
Now, from
the left-side Toolbox, activate the Free Select Tool.



And enter the following Add to the current selection and Feather 2 settings into the left-side Options Box.



Then
click-and-stretch a “Lasso Line” around the left-pupil

Free Select Tool For Beginners

Tip - Retracing Your Steps
Whilst you are applying the Lasso Line; - and before the Selection Marquee has been
applied, to go back one step - press your Keyboard’s Backspace Key. Press the Backspace Key for however many steps you want to go back - (this is for Window PC users, I am unfamiliar with Mac’s). Tapping the Escape Key completely removes the Lasso Line/Selection Marquee.



After you have clicked a Lasso Line around the pupil in a complete circuit, pass your cursor over the exact point where you began, and then left-click. Left-clicking completes the circuit and transforms the Lasso Line into the following Selection Marquee.
                        
 


Now, isolate the right-side Turquoise Pupil with a Selection Marquee, in exactly the same way as you did with the left-side Turquoise Pupil. 

After you have isolated both Turquoise Pupils with a Selection Marquee, you are ready for the next step.



Tip
Disable the Free Select Tool by clicking any other Tool from the left-side Toolbox. I always activate the Move Tool.

3/ Feather The Selection Marquees
To Feather the Selection Marquees’ edges, right-click over one Selection Marquee, and from the subsequent drop-down list, choose Select and then choose Feather.



Then, from the subsequent Feather Selection dialogue box, set a Feather selection by value of 6 (Pixels), and then click OK.



Feather Note
Feather settings are dependant upon your image’s
Resolution. Therefore, when working with your own image’s, it’s important to find the correct Feather Radius for you.



4/
From the top menu, choose Colours and then choose Desaturate. And from the subsequent Desaturate dialogue box, mark the following Lightness settings, and then click OK.





5/
To further darken the Selected Pupils, from the left-side Toolbox, activate the Dodge/Burn Tool



Then set the following Burn settings into the Options Box.

Burn Tool


Tip
You can quickly alter the Brush Size by tapping your Keyboard’s Square Bracket Keys
.



Now, darken the pupils by left-clicking and applying the Burn Tool inside both Selected Pupils - as illustrated below. (I Applied the Burn Tool 6 times to each selected pupil).

Note
Reapplying the Burn Tool will increase the darkening. Therefore, be careful not to over-darken the pupils. If necessary, tap Ctrl then Z to step backwards.
 


6/
Now, from the top menu, choose Select and then choose None.



Tip
If necessary, you can minimise any stubborn turquoise pixels using the Burn Tool.

Note
I changed the Burn Tool’s Brush from Hard to Fuzzy, and I also changed the Range from Midtones to Highlights.

             

Smudge Tool Tip
You can soften the demarcation line between the pupil and iris by activating the Toolbox’s Smudge Tool.
 


Now, enter the following settings into the Smudge Tool’s Options Box.



Then left-click and carefully soften the demarcation line - as illustrated below.



Tip
Return your image to its original size; View then Zoom then Zoom Out.
