The Swiss fast lane revisited0

There have been a few questions about my previous post on oversynching Elinchrom Ranger packs using a PocketWizard TT1 transmitter and plus II reciever. One kept coming up, so I’ll address it here:
Yes, although I initially thought not. lt turns out I was getting a strip of higher exposure right after the abrupt transition to unexposed area at the bottom of the frame. I missed this because I tended to compose it out of the frame, shoot objects where the variation looked natural or the mix with ambient light obfuscated it.
You can see the variation clearly in the above image (taken at 1/400th sec). With a high megapixel, low noise camera this isn’t too much of an issue to deal with by cropping or running a gradient in Lightroom.
You can use it to provide an effect:
Alternatively you could arrange so that the flash illuminates the top or left hand side of the image more than the bottom/right. Or rotate the camera upside down while shooting in the landscape orientation outside ( suggested by Tristan Shu ) and put the over exposed band in the sky where it won’t appear.
The main issue with this band would be if you were using Ranger packs for light alone. Then the variation in exposure would not be mitigated by any other light sources and post processing or careful lighting would be a necessity.
Thankyou to everyone who emailed. I hope this helps!
