Flash Exposure Changing in Manual Mode (V6 + Nikon)
If this has been addressed previously please point me in the right direction, but I had a frustrating team photo experience this week that has never happened to me before with the V6. The triggers were being used with a Nikon D3s and SB-700/910 flashes. The camera was locked down in manual mode: 1/250th at f/8, ISO 200 (no ambient contribution). There were SB-700's as Group B for edge lights, and SB-910 as Group A key. I haven't updated the firmware in some time, but I believe the last on them was when the flash unlock command was introduced.
1) Problem the first. Despite the V6 sending only a manual power signal, and the D3s being in Manual mode, the flash exposure changed with the camera in portrait vs. landscape orientation. If I set exposure while camera in portrait orientation, it would underexpose in landscape. If set in landscape orientation, it would overexpose in portrait.
2) Problem the second. Adjusting aperture (still full manual on the camera) had no apparent effect on flash exposure.
3) Problem the third. One of the edge lights wasn't firing when triggered despite it appearing to do so, test trigger worked, all channel settings and such fine. It didn't light up until I first did a full power burst and then reset back to the desired output. Likewise flash power changes didn't respond until I did the same thing.
I am completely perplexed, can't even make up a reason why such things would be happening. Hoping somebody can provide some feedback.
