Originally posted by P. Soo I read many times in these forums that the use of a lens hood, while not absolutely necessary, is highly desirable to improve image quality. I think it must be true, but the use of hoods is a real pain in some cases since many are very large and a nuisance to carry around. Is the use of a hood mainly for shooting towards the sun or a light source? Will there be any loss in image quality if I shoot without a hood with the sun at my back? Does anybody have comparison shots taken of the same image with and without a hood. I'd love to see if the differences will induce me to become a hood user.
It's not that you need the hood when shooting toward the sun, you need the hood when the sun is at an angle to your lens. Without a lens hood, your photos can suffer from flare, reduced sharpness and reduced contrast. Of course, some lenses have coatings that do a good job of ameliorating these issues.
What lenses are you using that have overly large hoods? With some lenses, the hoods will reverse-mount on the lens for easier portability.
