I've been sent this very interesting picture of tom's eyes, I'm sure you've already seen it :
Question : Are Tom's eyes changing, just like weather or something ?
1srt answer : well, then, his skin color is changing too girls...
"do you mean those pictures are fake ?"
Not at all, I mean that each and every camera are different. Take the same picture with 5 different cameras, you'll have 5 shades of white/green/blue or whatever.
So, this picture is first explicable by the different cameras and flashes.
And very very obviously, by the picture editing, for there ain't no professional photographer taken pictures without editing details, light and colors first.
You can very clearly see the 4th picture is very yellow, so Tom's eyes look green.
Then of course, you have the light.
Light your eyes from the right, from the left...from far, from close, you'll never get the same colors.
"But eyes can change right ?"
Hum, you know, if eyes could realy change (and sometimes they do, but not from day to day but from years to years), security agencies would never create security systems based on our eyes...◔_◔
