“Glare”, “shine” and “gloss” on the surface of an object are perceived when the ratio of specular reflection to diffuse reflection is large. As most of visible objects diffusely reflect a part of the illumination light, they look same even the view position shifts. Diffuse reflection occurs when light reflects off a rough surface and forms a blurry image or no image at all. A well-polished surface such as a mirror gives almost perfect specular reflection, but if the surface is not flat or rough, it will have diffuse reflection.Īs for visual and camera images, the reflected light is perceived as the light source itself in case of specular reflection, while the reflected light hardly tells light source because it is reflected at various angles in diffuse reflection. Regular reflection occurs when light reflects off a very smooth surface and forms a clear image. On the other hand, the reflection of incident light in various directions is called “irregular reflection” or “diffuse reflection” 1. We get to see clear images when image is formed by regular reflection. Regular reflection happens from a smooth surface, e.g. Irregular Reflection: There are many other reflective surfaces besides mirrors. The image is in form position with complete clarity and visibility. Common examples of regular reflection are silver, mirrors etc. It is called “regular reflection” or “specular reflection”. When all the reflected rays are parallel to each other, this case of reflection is called regular reflection. Characteristics of Regular Reflection: In regular reflection, when light falls on the smooth surface reflect in a parallel manner. The state where the incident angle and the reflection angle of the light are same against the reflecting surface according to the “law of reflection”. At this time, when the light coming from one direction is reflected to go in the other direction. The light from the source to the subject is reflected on the surface of the subject. Regular reflection (specular reflection) and irregular reflection (diffuse reflection) Reflection of the subject is checked hereinafter. To create a regular reflection, the roughness of a surface must be less than the wavelength it reflects What is diffuse reflection Diffuse reflection is reflection of light waves from a rough surface, like a rock. Here I would like to check the reflection of the subject. Regular reflection is reflection of light waves from a smooth surface, like glass. Light from the subject, as the secondary light source, is condensed and imaged through the lens. Browse 6,900+ regular reflection stock photos and images available, or start a new search to explore more stock photos and images. In case of reflective light, light from the light source is reflected by the subject. Such head coverings must be of one colour and an even shade.In order to take images with the camera, the light from the subject must be imaged on the image sensor. No, applicants can only wear head coverings for reasons of religion or belief, or if they have suffered hair loss due to medical treatment and wish to cover their head on the photo. Yes, applicants may decide themselves whether or not to wear glasses in the photo. When mirrors reflect, the reflected image will be backwards, but if you reflect something twice, it will look normal. Yes, but not too long: eyes and face must be fully visible. What is/isn’t allowed? Photos for passports, identity cards and driving licences: what is/isn’t allowed Item If it has any doubts, the organisation issuing the travel document or identity document has the right to ask you to provide a medical certificate as proof. You may not be able to comply with all the requirements for physical or medical reasons. Exception for physical or medical reasons
