PANCHROMATIC IMAGE PROCESSING - URBAN AND NON -URBAN CLASSIFICATION

Dear all ( from a young researcher),

I need to extract nice land use classification from old panchromatic photos 1954 and 1968 with quite good resolution: 0,96 m.
I am not an expert in image processing of panchromatic ones. I know that I will build a model to test the quality of image enhancement many times, but at the moment I need some advice in:

1) how to get rid of the shadows or at least decrease their effect? (ERDAS 2013, ARCGIS etc.)
2) how to extract water bodies from PAN? I work with coastal areas with many inland water bodies...
3) any suggestions for a urban - non urban classification? I was thinking about combining results of textural and spectral enhancement (new channel from combining the TEXTURE AND CONVULTION in ERDAS 2013) and setting a  treshold in the model maker


I would appreciate some tipps,
many thanks!
