Did the Cactus v4 Cause this banding? - PhotoCamel

wsolum · 4 Weeks Ago

I did a senior shoot Monday and the images from the first portion turned out fine but the second portion where I used a Cactus v4 on my Canon 5D had terrible banding across the upper third of the images.

A few tests back at the studio show now problem with the images with or without the cactus.

If it wasn't the cactus, what could have caused this? If it was, then why does it seem intermittent?

I have never experienced this problem before.

Thanks,
Wayne

I dont see the banding the image looks black to me. Was it you sync speed too fast?

It is a bit dark but not black. Here's a different shot with exposure bumped up to emphasize. Shutter speed was 1/30

Okay - here's the image . . . (I think).

CF card problem? Cactus might show a dark black banding if it can't keep up with the sync speed but I don't think that has anything to do with ths!

If not the flash card - well it may be a camera problem

looks a bit like rfi, but rfi would usually affect the whole picture
