Photographs
The reading is only as good as the picture.
You need two frames. The right eye, close. The left eye, close. Daylight, no flash, no beauty mode. If the colour is sharp, Daniel can work.
- Pupil. It should be a clean dark circle, not a white blow-out from a flash.
- Collarette. The inner ring of the colour. It should be in focus.
- Iris. The coloured part fills about half the frame.
- The white of the eye stays visible around the colour. The lid does not cut across the top.

Ask someone else to take it.
The rear camera is sharper than the front camera. If you are alone, use the rear camera and a mirror, and check the result on a large screen. A front-camera selfie is the last resort.

02
Face a window. Leave the flash off.
Soft daylight from the side or the front. No direct sun in the eye. No ring light parked in the pupil. If a bright dot sits on the coloured iris, move and shoot again.

03
Come in close.
About 10 to 15 centimetres. The eye fills the frame. Hold still. Tap the screen on the iris so the focus lands there, not on the eyebrow.
-
04
Open the eye fully.
Look straight at the lens. Both eyes open. If the upper lid covers the colour, a clean finger can lift the brow gently. Do not press the eye.

05
One eye at a time.
Name the files right.jpg and left.jpg, from your own point of view. A third photograph of both eyes, a little further back, helps with colour. It does not replace the close pair.

06
Turn the improvements off.
No portrait blur, no beauty filter, no black and white, no extra sharpness from an app. Wipe the lens. Take glasses off. Take coloured contacts out.

07
Check before you send.
You can see the pupil, the colour, and some white. The colour is crisp when you zoom in. The file is the original, not a screenshot of the photograph.

Add a few lines about you.
Age, what you came to understand, medicines you are on, and anything a physician is already treating. The iris is read beside that, not instead of it.
