For Christmas my mom got my family a canon rebel t3. I'm used to my old point and shoot but know that this camera is more than that. I would love to know what type of settings (iso, aperture, and shutter speed-think that is all...tried googling it) is good for capturing night castle pics and parade pics...fireworks and anything else you might be able to clue me in on. I would love to get some great pics when we are there in Feb. If anyone could help me, that would be great! Thanks in advance!
