I went for a walk in Bush Pasture park today. I wanted to try using my iPod Touch to make a value sketch before starting a watercolor. I sat on a concrete bench and did the value sketch first. Then I took a reference photo and used the PhotoFX app to generate a charcoal sketch version to see the photo in black and white (like a value sketch). Finally I sketched in my Moleskine with a Pilot FriXion 0.5 erasable pen. Then while checking the value sketch on the iPod, I used watercolor to sketch in the colors and values. Here’s a slideshow of the four together.
By doing the value sketch first it helped me to see the areas of light and shade. I need to make my darks darker and remember not to use Burnt Umber in the dark greens (Payne’s Gray works better – doesn’t look so muddy).
