Early Morning Sun on Sgurr Mor

Early Morning Sun on Sgurr Mor (sRGB)

It was a beautiful morning today with bright sunshine on Sgurr Mor across Balmacara Bay from our house.  I got this shot with a graduated ND filter to avoid blowing out the sky which has really interesting clouds I think.  The colours appear to have changed a bit since exporting from Lightroom, not sure why, but will have to investigate as the image is not a fair bit darker.
OK, I have just learned something new.  I was reading somewhere that when editing images in Google's Nik Collection it is best to use ProPhoto RGB as opposed to sRGB colour as it gives the best range and tonality apparently.  This may be the case but when exporting from Lightroom it makes the images darker and gives them a blueish tint.  So, I have now replaced the top image with one in the sRGB colour scheme and it looks much better compared with the ProPhoto RGB one below..
