Use this short list to decide whether the current photo is worth continuing with.
Follow this sequence to keep the workflow clear and reduce avoidable mistakes.
Turn off direct flash when possible and use brighter ambient light instead.
Move the main light source away from the lens so reflections do not bounce straight back.
Take several frames after changing the light setup because small adjustments can remove the problem quickly.
Review the eyes at full size before you treat the image as ready to keep.
Red eye is usually caused by light bouncing back from the eye straight into the camera.
The issue is not only cosmetic. It changes how the eyes and face are read.
The safest fix is usually better capture conditions, not a heavier edit.
This decision should be quick and practical.
Use the product flow after the source image is already trustworthy.
It can. Red eye makes the eyes look less natural and can weaken facial visibility, especially when the problem is obvious at full size.
Usually a direct flash or another strong light source close to the lens causes red eye by reflecting back from the eyes.
A retake is usually safer when the problem is obvious. The cleaner move is to fix the lighting setup and capture a stronger source image.
Use brighter ambient light, avoid direct flash near the lens, and review the eyes at full size before continuing.
Use the upload flow when you already have a source image, or keep exploring the guides if you still need to fix the setup first.
