Hi guys,

I'm new to LF and just got a 8x10 LF camera and a 240 Sironar-S lens.

Today, for the first time, I looked at the groundglass with the lens and saw that the image is well illuminated only in the center. At the edges it gets quite dark.

Everything was set up correclty, no movements such as rise or fill, I realize that I don't have too much room with the 240 ...

When shooting a sheet of 8x10 film, how come the image will be well lit overall whereas on the groundglass only the center is really getting much light?

Is there a difference between what one sees on a groundglass in terms of vignetting than what one will get on film?

I know this might be an easy answer, but I'm new to this kind of photography, i.e. working on a groundglass ...

Kind regards

Paul
