To make the comparison, I have used a standard 300gsm "not surfaced" paper and the following paints:
- W&N Cotman UltraMarine - normally very flat and uniform,
- W&N Artists French UltraMarine - naturally granulates providing an artistically uneven wash
I'm very impressed with the results. Once the granulation medium is added, it's very difficult to tell the difference between the Cotman and the Artists UltraMarines. I think the granulation medium adds depth and variety to the Cotman paint, and will be very useful when a flat wash is not required.
This photo shows the paints whilst still wet:
And this one shows the paints now dry:
- W&N Cotman Turquoise - normally flat and uniform,
- W&N Cotman Cerulean - normally flat and uniform,
- W&N Cotman Alirizan Crimson - normally flat and uniform,
- Derwent Aquafine Sap Green - naturally granulates providing an artistically uneven wash
- W&N Cotman Burnt Umber - normally flat and uniform,
- W&N Artists Burnt Umber - naturally granulates providing an artistically uneven wash
