While it's good to have zoom, red eyes a lot of the time are NOT round due to 
eylids.  So the tool as is is frustrating to use.  Also, it`s annoying and slow 
to have to select each eye separately.


Currently, the red eye zoom expects to remove the red from the entire area that 
is denoted by the circle created with the tool.

This is incorrect behaviour.

The red eye tool should be smart enough to only apply the correction to the 
area within the denoted circle that is actually RED.  This is quite simple to 
do.  Simply make an irregular mask based on a red filter.  Once that is done, 
take the original image section corresponding to the new mask (a subset of the 
denoted circular section), and correct the redness.  This makes it quite a lot 
easier to fix all manner of irregular shapes.  It removes any red from a 
subsection of the image (leaving other valid red areas... jackets/scarves 
true).  You really only need to define a range of colour which is considered 
red to create the irregular mask.


This also paves the way to selecting both eyes at the same time, or even using 
a square area... it will be irrelevant what the shape the user denotes since 
only the red areas within that shape will be modified.  All red-eye tools I 
have used before did this at least.


In addition, this paves the way for enhancing this to autocorrect red-eye for 
the entire picture, with one click and not specifying an area at all... the 
picture is the area that the algorithm would be applied to.  Since this will 
possibly cause more collisions with other valid red ares, it would likely need 
to be enhanced.  You simply need to marry the above to eitherto 

a) face detection to make changes only to anything red on a face
b) shape detection to make changes only to anything resembling a series of 
shapes (circular, oval, partially closed bottom, partially closed top, etc.)

Magic.


Just my 2 cents.

Not to worry - hearing from multiple people asking for the same feature can
highlight things that our users really want, and as such, helps us know what
should be prioritized.
