Some of my macro photos

I'd love to see an explanation of how there can be two different focus points.

Keep in mind..... the 'reflection' is NOT as the same focus point as the iris in the eye. It will be twice the distance from the eye to the reflected subject.

I really don't know what to tell you. The only thing I did to that photo was do some color editing in photo shop, it's absolutely not a fake reflection. And the focus point isn't on the reflection, it's obviously blurry. The focus point is on the eyelashes in the reflection honestly. The iris is a little blurry, as is my reflection.
I used an external flash on my camera, point it at my friend, shot the photo and was extremely impressed. I have a few that were really blurry and then that one came out perfect. If you think it's fake, then keep on thinking it but it isn't. Like I said, I could show you a completely unedited, untouched version of this photo... in fact I think I'll post it.

Oh don't worry this is nothing, we're up to 5 pages already on the latest 'newbie who wants to become a pro' thread :lol:

sooooo agree haha, that is nothing compared to some replies.
:)
also don't take it personally , a reflection can be added after for an effect, it happens.
what would be insulting is if you stated, "no post processing, this is a real reflection" and then someone stated "yeah right."
hopefully no one would be so rude as to do that.

Well, I stated that it wasn't a fake but I'm still getting told it looks fake. Oh well! Posted my originals. I know it's not the worst comment, I'm just kind of taken aback I guess because I didn't think it looked fake whatsoever.
 
Love #1 and I do believe it's a real reflection! The only thing that's bothering me a little is that the ISO noise seems to be a little high... But I imagine that was needed.
Great shot!
 
The reason for this is because the iris is not located on the reflective surface. It is in fact slightly behind that surface.
Because you are focusing slightly behind your reflective surface (which in this case also happens to be opaque like glass) you get two focal points.
With a plain glass surface which hasn't been curved this would result in two focal points at the exact same distances from the glass, one in front of it and one behind it.
The surface of the eye is curved though. This messes up the distances.
Because of the curve your reflected focal point is moved way backwards, which is why you can easily get a person standing in front of the eye in focus while also getting the iris in focus.

Here's a quick sketch I made showing the reflections on a straight and a curved surface.

The more curved the surface, the further the focal point.
Theoretically, if you have surface which curves inwards instead of outwards, the focal point will move closer to the surface.
