Here's a photograph:
Next I convert it to black and white - then I'm not distracted by the color.
I make a quick sketch of the darks only with a fat felt tip pen. If they make an interesting pattern..I'll follow that in my art work. If the pattern of darks is boring...then I'll tweak it a little. You can also see see if there are any major mistakes with balance, or rhythm. I find the position of the lights much less important...the weight is with the darks even if they're not all that apparent when the piece is finished.
Finally, I print out the photo and the value sketch - whether for a quilt or a painting -.
and now I'm ready to make art!!! Stay safe and healthy - making art is not dangerous and you don't even need to wear a mask!! And, if you have been, thanks for reading...and please comment and tell me your working method...I'd love to know. elizabeth
