Hood Canon Eos

Hood Canon Eos
I took a picture, and there is a ring of light, what caused this?

Here is the photo. http://i120.photobucket.com/albums/o182/marlabmarrs/IMG_0999.jpg I had a Canon Eos Rebel XT, when I was using a lens Canon EF 28MM 1:1:8 and had a hood on it .. I wondered why that occur ring

Well, I was using a bell, but you were still firing directly at the sun! The hood can not prevent the protection rings lens from the sun if it points directly at the sun and you were looking absolutely dead on, straight into the sun. Okay, you're wondering how other people take pictures of the sun without this ring of light and I think the key is how the sun is right at the top of the barn, creating a strong contrast between stable dark and clear sky or something. Anyway, everything was "correct" in this instnace to get the outbreak. If you're a little to the right or slightly to the left you may not have done so badly. You can try to limit further opening the diffraction around the blades. You were at f/11 to 1 / 1250 at ISO 100. You do not can choose a lower ISO, but you could get the same f/6.3 EV in 1 / 4000 and may not have much flare. "Next time, right? Check LCD image and see if you have the extreme flare and then change the aperture to see if I have better or worse when you try the new configuration. On the other hand – there are people out there right now – including me – they are saying, "I wish I could do that when I wanted!" It may not be what you were expecting, but still being a very good image.
