Hi, auroraskye,
if I haven't done it yet, welcome to
RP!!
I had a go at your picture... you and everybody have done an excellent job on the tape so I didn't do anything about it ... I concentrated on "
shadow/highlight balance" particularly in lifting the 'blocked shadow along your Granny's arm and highlighting her lovely face while minimizing the noise
**...
I haven't much time for a detailed explanation right now, but if what I did goes in the right direction I'll post it as soon as possible.
**To get rid of the noise, I use
Neat Image (a Noise Removing software which comes in 2 versions: as standalone only (free) or with the addition of a
PS plug-in (not free))... Neat Image can be downloaded
here and on the same page you will find the links to manual, support, tips and tricks..
