Fair A' Far Dam
This isn't as massive as Niagara by any means but I am always 'drawn to it'. To the extent that I have hundreds of shots of it - and people far & wide, know it as, "Nik's Waterfall". I have a postcard made of it, for self-promotion. Shot with a Konica Minolta fitted with a VCG and Sony 18-70 [at 26mm]. Taken handheld from the carpark at the bottom of School Brae in Cramond, Edinburgh. The flashes of colours within it are caused by a Cokin Universe diffraction filter.
