That looks promising, but I'm wondering about colour, and why you chose to 
convert to B&W.

Old lenses that predate colour film (certainly 1890) are generally not 
corrected for colour.

On the colour images, do you see any evidence of fringing or CA? It would 
probably be most prevalent in the corners, where spectral dispersion would be 
expected to be greatest.

Every now and then go away, have a little relaxation, for when you come back to 
your work your judgment will be surer. Go some distance away because then the 
work appears smaller and more of it can be taken in at a glance and a lack of 
harmony and proportion is more readily seen. -- Leonardo da Vinci
