Working on lots of sky studies at the moment. This is 31x41cm on Hot Press S.Waterford. Interesting experiment on this one - I bought a tube of MaimeriBlu Cyan months ago - as Edo uses, but it's so intense I wasn't sure how to use it. So I mixed it with white!! to make a deep cerulean sky color. I ended up mixing way to much of it as it is so intense a pigment - so I've saved it in a jar. The thing I like is that it doesn't granulate so I could build up a color that matched the true color of the sky. Cerulean is also quite expensive so this could save me a few euros!!
