I love the lightening shot, I am a complete novice so no critique. I would however like advice on shooting lightening. Is it absolutely necessary to use a tripod? What are the best settings to use? Many thanks.
I used a 3 second exposure, so it was absolutely necessary to use a tripod. Having the exposure that long allows more light into the shot so you can actually see the lightning. Also, if you try to go for a fast shutter speed, your finger may not always be speedy enough to catch the lighting

When I got this shot, I just sat outside during a storm and continually pressed the shutter release, even if it wasn't lighting. That way if there was an unexpected flash of lightning, I was able to get it. Anyways, that's how I did it, though it's not the only way, and probably not the best way, of getting lightning shots
