OK it is subjective, and we could be wrong. But to me they are all SAD, different angles, ages, expressions and resolutions.
So post me an image, or any number of images, that illustrate what makes you feel comfortable with your assertions.
Without images, all you are providing is an opinion.
The real problem, it seems to me, is that almost everyone WANTS Stanley Ann Dunham to be the girl who posed for the photographs.
And WANTING doesn’t make it so.
Frank Marshall Davis had five children, four daughters and a son, who were all born after his arrival with the wealthy, attractive Helen Canfield Davis, his second wife, in Hawaii in 1948.
He was a short, barrel chested, thickset man - born in 19O5. He was fifteen years older than her father!
There used to be a guy called Dakkster here on Free Republic who kept saying he saw no resemblance between Stanley Dunhman and Barack. Every time he would say this, he would post photographs of a very old Stanley, and a very young Barry, and say he couldn't see any resemblance. Everyone kept telling him, "You need to select photographs where the men were similar ages, and then it becomes obvious they resemble strongly. "
It often does no good to make comparisons between photographs when they are taken at different angles. Some people resemble someone from the front, but look different from the side. It is a characteristic of three dimensional images rendered onto a two dimensional surface. (a photograph.)
Comparing front and profile photographs with photos from a combined angle is not always easy for humans. Computers can do it perfectly, but people aren't so consistent.
