I took the opportunity of the storm last night to test out two features LIVE COMP and LIVE TIME of my new camera. The Little Olympus, OMD EM10iii Mirrorless Camera. LIVE TIME lets you see a long exposure building up the image on the LCD screen (in 2 second updates so the lightning just lit up the whole sky (looked like sheet lightning, which it wasn’t)
Whereas LIVE COMP (the image above) takes a back ground image and then only add things that are stronger light, (again I'd set this to 2 second intervals), its like I am doing highlight blend mode across several images (say 50 to 100). That’s how I got this photo with the forks of lightning and strong frozen backlighting of the tree. Yes I have cropped in a bit.
