Photographic chemicals in 5 gallon plastic bottles on a wooden pallet, a visible product load for vans/box cars. Referenced mesh assets by MSGSapper use non-parallax PBR textures. Photographic chemicals include fixer and developer and were in wide use as part of the process to convert exposed camera film to negatives and/or prints in the era before digital photography. Most users of cameras sent their film away to be processed by a lab but many professional photographers developed their own film. This had to be done in almost complete darkness in a dedicated darkroom. Digital photography has largely rendered this process obsolete but film photography is still enjoyed by a significant number of professional and amateur users.
