d-23 straight for 5 or 6 minutes and 2% solution of Kodalk (this is balanced alkali... 20 Mule Team will work also as it is borax) for 4 or 5 minutes. Give an extra stop worth of exposure to support the shadow area and hope. If I read your post correctly you are talking about that seen you posted that was washed out in the outside part of the scene. Is that correct? Someone mentioned using a larger format and that will help. Also, if you don't have the ability to mix d-23 use Microdol-x and Kodalk.
