It's a completely different experience!
For years, I have thought about doing some Plein air painting, it all seemed so romantic, but being so visible to everyone going by was a bit scary. I thought what if the painting wasn't perfect I would be humiliated, and with so much external stimulation it would be overwhelming and not knowing what to focus on.
One day we had a power outage, it was a beautiful day, warm, with blue skies, so I threw some old tubes of color into a bag, a block of paper, and an easel (that I never used) and went for a drive, so, this is what happened.
What was fascinating about that experience is that it forced me to release all of the distractions around me and focus on what I had control over. Another obstacle I had was thinking that I needed to have the perfect line drawing but for this technique it doesn't matter.
You don’t really need a great location, only to be inspired and let your imagination go to the surrounding shapes, space and color. Lighting conditions don't need to be perfect and even with time is limited, (just 20 - 30 minutes) you can paint leaving you with feeling creative and re-energized. Simply allow the water on the surface to carry the color and create some magic.
