The Vaseline trick was made famous by Bob Guchione (sp?) of Penthouse magazine although I suspect it is a very old trick. I am not sure I want to do this to any of my lenses.
Tessars will produce just awful images when the front cell is removed. The back cell contains most of the power and most of the correction is in the front. I don't think you would want this effect except for some special effect.
I don't know how to adapt the Dagor to a digital camera because I suspect its focal length may be much too long although Goerz made some short FL versions of the lens. The soft focus effect is small and exists when the lens is wide open, nonetheless it gives a pleasant softness for some types of work. The effect is best when the complete lens is used. A single Dagor cell is useable with about 1.8X the focal length of the combined lens but the most obvious aberration is coma which is not very pleasant. Coma subtracts when two identical lenses are used back to back, as they are in the combined Dagor, but spherical adds so that the complete lens actually has more zonal spherical than a single cell.
You might be able to expeiment with an adaptor as simple as a cardboard tube and some tape.
