Today was my first day this spring getting outside to paint. It was marvellous... I found a quiet spot in the sun by a creek. It was partially cloudy out and so I would occasionally have very bright sun on the view, followed by cloud cover. As you can see in the 2 pics below - it can sure makes a difference to your colours and values when it is cloudy vs sunny. I attempted to get the 'sunny' view - however - I made the mistake of bringing a canvas stained with a deep orange. I think for my Plein air painting - a lighter warm colour (grey or Sienna) would be better.

Only wildlife, other than geese overhead, was this colourful fly who sat on my easel for a few minutes, warming up. Would be cool to paint him, but he didn't stick around long enough.
I did two fairly quick 'sketches' - one is the general view - very thinly done with thinner and oil - so the orange really shows through too much. The other was just a 'sketch' of the little tree in front of me. Both I 'erased' after to reuse the board for my next time out. I just made sure to paint the panel a light grey for next time.
