Aperture priority? im still new with the whole photography thing. focusing issue is great, im not sure what to do with that, its not so much the lighting i mean my stock flash wasnt terrable but it wasnt great. because of that my shots wernt that clear and focused. when i had the flash on i could only use shutter speed 90 when normaly for action shots iv been using 2000. i deffinetly know i need a speedlight but even the fact with the shutter speed i dont know how to fix that if you could help me with those problems id be happy but thanks for everything else.
Hey matty reps,
Aperture priority is a setting on most SLR cameras where you choose the aperture, which is the size of the opening in the lens that lets light thru, and the camera chooses a shutter speed that provides a correct exposure. The smaller the opening in the lens the less light that gets thru to expose the film so the shutter has to stay open longer to provide a correct exposure, but the smaller the aperture you use the larger the depth of field. Depth of field is how far in front and behind the subject things are in sharp focus. Canon refers to aperture priority as Av mode. With flash photography the camera usually sets the shutter speed to a designated speed called xsync speed, which is probably 1/90th of a second since this is what you said the camera was setting it to, but that speed is irrelevant since the duration of the flash is what determines the exposure time with flash photography which is usually around 1/10000 of a second (easily fast enough to stop almost any action). In aperture priority with a flash the smaller the aperture you use the more that will be in focus but more light will be needed from the flash and the closer you will need to be to your subject. A hotshoe mounted flash will help tremendously. I hope I didn't confuse you more, but as I said before you are attempting something difficult to do in photography. Keep trying and you'll get it!
Sincerely,
Allan
