Thanks for your help
Yeah Smith did use compesatory fill and bumped up practicals (christmas lights) etc. The push process was used more to achieve a specific look than to facilitate low light levels. In order to make the lights appear much brighter and to flare out.
He also used a Tiffen Low contrast filter on night time interiors. Im thinking of maybe using a pro mist to make the highlights flare out as another alternative.
If anyone has any other suggestions they would be much appreciated
Thank you
