I have recently been on a kick to shoot the sunrises here in Brasilia, Brazil because they are just a beautiful sight to behold. Some days very red others orange yet others more white. I am playing around with various f-stops up to f64 and shutter speeds to see what kind of shots I can get. I am not using any kind of filters as of yet. Maybe if the sun was higher in the sky I would have to use filters.
After I took the shot I had to check my camera out. I thought I had some sort of dirt or oil spots on my sensor. I couldnt believe what I was seeing. My friend Lucas Ferreira,student at Universtiy of North Brazil, pointed me to a video from NASAs site called NASA SDO - One Giant Sunspot. After watching it I felt better knowing my sensor was not dirty or damanged!
One photo I uploaded was from 10/17 and it didnt show a massive sunspot. Another photo I attached shows a large sunspot in the lower right section of the sun, then on October 24 I decided to take some shots of the sunrise and you can see what I got.
