Love taking pics of lightning, and yeap it’s pretty easy once you get it down. There’s a program called Imagestacker that’s great for repetative frames with same background. Can stack lots of bolts for a major cool pic!!!
What I do is find a distant focal point and get my focus first. I use a narrow aperture, low ISO setting. Then put the camera on bulb setting and hold the shutter open till I get a lightning flash.
If its a good dark night you can keep the shutter open and capture several lightning flashes.
