It was windy the next night, and I got started a little later. some were 1 second exposures. One of my cheap umbrellas got damaged from a fall ( I had it weighted down too). Orange filter used on the flash units to increase the blue in the sky. Anycolor filter can be used on the flash units which will be corrected in software or the camera, the elements in the photo not lit up by the flash will have a color shift.
