I am using Poser Pro 2012 on a Win 10 64 bit system. I first installed Poser on my old Win 7 computer some years ago. As I use my computer for work as well as leisure I created 2 user accounts. Poser installed itself on both of these accounts. I noticed early on that my renders of the same subjects came out differently. One was significantly lighter than the other. I was using the same figure, skin mat and lights. I preferred the lighter version so did all my 3D work on this user account. Some months ago my computer became ill and I replaced it and reinstalled Poser and imported my old runtime. Unfortunately my renders are coming out dark. I have tried increasing the intensity of the lights and this helps but I cannot seem to recreate the same image with the adjusted one looking a bit washed out.

I am attaching some sample renders. The figure is Barliecorn but has Caludia SSS skin mats and I'm using some lights by Sveva. Any thoughts?

At a guess, it's your render settings.... Try these and see if things are more to your liking!

It seems to me like a Gamma Correction problem. Look at your render settings and note if Gc is ticked on and set to 2.2. That would be the only reason, I can think, would cause your renders to suddenly go dark.

Yes that has done the trick. Thanks to both of you.
