I am getting a lighter edge on the bottom of my images.... I have googled and can't seem to find anything that points me in the right direction to the cause. Any ideas?
Info:
Canon 6d
OrLit Speedlite RT-600
Gary Fong Speedlite diffuser



The whiter edge is there regardless of landscape or portrait shot (portrait shot is is on the right side which would be the bottom of the image.) However it is not on every shot!



Landscape Shots - shot one after the other:

ISO 100
85mm 1.2
1/640
speedlite set to high speed sync



image without light edgeImage with light edge



Portrait shot:
ISO 200
85MM 1.2
1/400
speedlite set to high speed sync



Light edge in portrait mode



Is it my speedlite malfunctioning? What would cause this?
I do have on an accordian style hood on the lens. The hood was not extended but was at the edge of the lens...could it be reflecting the light back into the bottom of the image? I'm mystified. I shoot raw and will be able to fix in post....

My bet is on the same thing you guess — light reflected from the diffuser bouncing around badly.



This is easily tested by making some images with and without the flash on. I'd suggest a neutral target (the infamous brick wall shot), and run through a range of apertures and flash power.



Assuming that's it — or actually, even if it's not — I'd suggest replacing the dome diffuser with an off-camera flash and possibly a a larger-yet-portable softbox. That sounds like it might be inconvenient outdoors, but the thing is, it's exactly because you're shooting outdoors. This style of diffuser does increase the effective flash area a little bit, softening light some, but its main effect is to scatter light in every direction. Indoors, that light then bounces from ceilings and walls, but outdoors (or in a large room), the primary effect is simply to waste light.



You can get that same effect for free and without risk of weird stray light simply by cutting the flash power. So maybe you don't even need to go the off-camera route ... but it's an option that will give you a lot more flexibility.
