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?
Fuck, my eyes have bloom problems in normal conditions.
Both my eyes make a faint double image a few arcminutes above the original. It's apparent whenever I read white-on-black text but the brain has learnt to ignore it. It is most visible when I'm tired, squinting or refocusing. Aberration too – RGB LEDs switching from red to blue seem to shift position downward by about the same amount. Again, the effect changes magnitude while squinting. I imagine my brain must be correcting for a massive amount of blue and orange edges to make sure I don't see them everywhere but the fix doesn't work for narrow-spectrum light.
Yeah, and I have a weirdly big and dark "floatie" in addition to the normal ones, too far from the center to see well and only visible when squinting against a bright area. And part of the retina seems to freak out and flash sometimes, which gets better after a few minutes with the eye closed. Been to the doctor and they found nothing weird...
