Output from regim black

[simondodd]

Hey there,

I am having a slight issue with regim (decided to try it as DSS isn't playing ball with me)

The preview image in Regim looks fine (lots of noise but generally fine) but when I save it as a tiff all I am getting is a black image. I've attached the two images. Is this normal and do I just need to process the image to get an output or have I screwed something up?

Thanks in advance.

After some pretty extreme processing I am seeing some data in the files however it's not as good as a single frame from before the stack... Might have to give DSS another go...
