Unless an iris is very unusal in color or markings it is almost impossible to photo ID as not only for instance a yellow self (all one color) the lighting, the monitor, the time of day, soil PH all have something to do with the pictures now include the camera. These factors all have something to do with trying to ID any iris.
As a judge as a fun test once we had 5 pink iris, all cut the same height had I think 8-10 iris names to pick from and in the group were several well known hybridizers and growers the nearest was 3 ID'd.
