Thanks Guys - it is a little regretfull - combinations of life and work - mean
that it's not that often I am 'with camera' so I can only photo what's there at the time
I have attempted some on the mobile phone - but it's really not up to the job!!
kgosded, yes but only a tiny bit plus saturation. i use GND filters from Cokin and sometimes they render color this way which gives a bit of a problem to correct. Cokins are not true GND unfortunately but are useful for amateurs like me.
