so im trying to shoot different sports. the camera i have is a canon rebel XT. as of now im trying to shoot surfing and i have a few questions about it. first of all im shooting from the shore sometimes the water flows over my feet. is this a good spot to stand or shoutd i be farther away? the lens im useing is a 55-250is canon lens. most of my shots are 640-1000 shuter speed. should i be shooting with a higher shutter speed? it looks like my pics are kinda blury when i view them in actual size vs. the fit to screen size on my computer.is that because im sitting to close to the screen therefore looks blury? should i use a tri pod? my iso is set to 100. im shooting in shutter priority mode.all help will be great!
