ما شاء الله عليكم يا جماعه شكلها كانت رحله جامده نفسى و الله فى واحده من دول
متقلقش يا كاريزما الاوربس دى مش زى ما الناس معتقده دى مجرد ظاهره طبيعيه عشان الكاميرات الجديده اللى بنصور بيها المسافه بين الفلاش و العدسه قليله فلو فيه ذره تراب حتى على العدسه او قريبه منها بتعكس الاضائه الخارجه من الفلاش فى اغلب الاحوال للعدسه على طول و بتظهر بالشكل اللى بتشوفه ده الدوائر دى

Due to the size limitations of the modern compact and ultra-compact cameras, especially digital cameras, the distance between the lens and the built-in flash has decreased, thereby decreasing the angle of light reflection to the lens and increasing the likelihood of light reflection off normally sub-visible particles. Hence, the orb artifact is commonplace with small digital or film camera photographs.

The orb artifact can result from reflection of light off solid particles (e.g., dust, pollen), liquid particles (water droplets, especially rain) or other foreign material within the camera lens.

The image artifacts usually appear as either white or semi-transparent circles, though may also occur with whole or partial color spectrums, purple fringing or other chromatic aberration. With rain droplets, an image may capture light passing through the droplet creating a small rainbow effect.

Underwater photographers notice the effect also, which occurs for the same reason as above-water photographic artifacts. Sand, small sea life or other particles close to the lens, invisible to the diver, reflect light from the flash causing the orb artifact in the image. A strobe flash, which distances the flash from the lens, eliminates the artifacts.
