I took some photos on a nice sunny day with my old Pentax K-r. I used fixed aperture mode because I like depth of field in photos. Settings for this particular photo are f/5.6, 1/100s, 55mm and ISO200 according to the exif data.
As you can see in this about 2-3 times zoomed in version of my photo, the yellow surface that is lit up by the sun radiates into the shadowy part behind it.
How is this effect called? How can I prevent it?
Based on the image Im assuming youre in the exclusion zone at Chernobyl. The hazmat suit youre wearing is covered in radioactive dust which is triggering the light sensors on your camera more than the rest of the image.
