The last of the town photos - will have to remember to look for this combo of colours as I really like their final result. I think it might have too much noise here too - need to fix it next time.
@granagringa@olivetreeann Thanks Madeline and Ann - These few Town photos were all taken on the same day - the sky was a gorgeous blue which gave this colour under the negative effect. The shiny silver roof gave the nice slate grey and the dark tower gave the light colour. I think I had a -1 bias on the camera - maybe that's why these colours appeared. Often the negative works well on only one part of the photo and is terrible on the others - so this was a lucky combo. Thanks again to both of you for your lovely comments. Cheers.
