When I was in South Carolina visiting my son and granddaughter, I tried some shots. Fast shutter speeds only produce little dots of light. You really need a tripod to take long enough shots to develop a background in the dark along with the streaks of the lighting bug's light. I did not have a tripod along on this trip and so my "successful" shots were few and far between. Pick a good background and treat the shoot similar to shooting fireworks but at a much slower shutter speed. I have seen some very successful lighting bug shots, but mine are not some of them. The next time I am in South Carolina in the summer with a tripod, my shots will be much better.

The community that I live in (Camphill Village Copake) supports several communities in India. Those communities, like us, create dignified life situations for people of differing abilities. My wife and I visited in January and I thought to show two photos here. The first is a gentleman who tore all of his clothes, picked everything in the house apart for years until a clever colleague gave him palm fronds and said:"you can make brooms." Now he sits on the front step of the house all day, content and happy, picking palm fronds apart which are then turned into brooms for the community. He is very proud of his brooms.
The second gentleman has Downs Syndrome and lives in a very impoverished village that receives support from one of our communities. He is sitting in front of his family's house, that is his father at work on the left - but look at that smile! That is how he greets everyone and invites them in for tea.
In these strange times I thought it might be nice for more people to see that smile.

Your camera DID move. It moved to the right and slightly up from the original photo. Look closely at your first print and notice a small stone located above the word "DOWNLOAD." (The stone is actually above the letter "D") Now notice your second photo and that stone is now 1/2 inch more left than in the first shot. It is also lower than the in the first. When you moved your lens you allowed different light to strike it. Thus, you have caused flaring. 1/2 inch seems trivial until viewing your photos but it is more than enough to allow problems.
