I took a series of pictures, 4-5 seconds of exposure each one, and merged them with PS. I had almost 100 pictures captured, 10 of them had a lightning. So, yes, 90 of them were just bright clouds.
I should have taken a shorter exposure one, like 0.5 - 1 second to avoid the bright church. I forgot about it. It looks a little overexposed but I eventually liked it

I definitely love this shot. The lightning is captured so beautifully.
