In examples, a relative skin reflectance of a captured image of a subject is quantified.  Based on the relative skin reflectance , the captured image is determined as suitable or not suitable for biometric identification.  When the captured image is determined not suitable, a remedial capture setting is calculated and provided to an image capturing resource.  Another captured image of the subject, captured under the remedial capture setting, is received from the image capturing resource.  The relative skin reflectance of another captured image is quantified and based thereon, there is a determination of whether the another captured image is suitable or not suitable.
