Lightning was working pretty hard north of my house last night and having never shot lightning before I thought I would give it a whirl. I wasn't sure how to approach this so I set the camera to full manual and adjusted shutter speed/aperture until the result looked right to me. Most were shot at 20 second shutter and 22 aperture. I have cropped to improve composition on some of these, but that has also made them grainy. I think the third shot is my favorite. How would you have approached differently or improved the results?
