Explore the original pencil sketches created in the field by Ferdinand Bauer and compare them with the finished watercolour.
‘The original pencil sketch has the colour numbers, but also some Roman numerals which indicate number of scales, number of fins and so on and so forth. But what is remarkable when we have the slider is we can actually see how he converted all of that into the finished watercolour. And I must say, the first time I saw this I was absolutely astonished to see his technique become live in front of me.’ David Mabberley
