If you don't collect the textures the tiffs are left as they are and Lux will handle them directly. If you collect then the result depends on the size selected: 

• if you select the same size as the original then the original tiffs are copied in the resources directory

• if you select a smaller size then the file is scaled and converted to PNG, no JPG.

There is no temp folder in use by Reality for this, so that part is related to Studio. If you have jpgs then there is something strange happening...
