Yep. That's the site. You have to email Admin and request to register.
Getting the lighting and angle the same is not hard. It just takes effort, imo. (And a good camera, I'm sure.)
For the angle, I just hold the camera half an arms length away from my face and snap. Level, or perfectly horizontal to my face, like if I were talking to someone. Level to my face is the easiest angle to get the same each time, for me. I also have the camera set to macro, and zoom in when I take pics. I use a mirror to see if the image is focused on the screen before I snap. Camera in one hand, mirror in the other at the same time.
After taking pics, I put them on my computer. I look at my older pics and the new ones side by side and if my skin tone doesn't match, I delete them. At this point, I don't even focus on how my eyes look. I think pics can make your eyes look all kind of ways and shades due to lighting, so I feel, at least if my skin tone is the same in the pics, I can feel confident that any eye lightening that I see, or lack thereof, is honest and true. I would also feel dishonest sharing them if it wasn't the same (but that's just me). So I put forth a little effort until I get one that matches so I won't be embarassed to share. (Off-topic, I'm still trying to get over being too embarassed to make a booby growth journal.
)
I usually have to take a whole lot of pics before I get a good one. When I find a good one I shrink it to a similar size of my previous pics, cut out my eyes, then paste them under my previous pic (line them up), and save.
Something that might help, not sure but, I take pics in the same place everytime, and I put on the same clothes. I heard different clothes can make your eyes look different colors, so I try to keep everything the same for the pictures.
