Step 1: The research I usually start from an artist / artwork I like and then dig into biographies, interviews, art books, both online and off line. I'm lucky to have a great library and love google books ;-)
Step 2: The composition Once I have decided to work on a specific artwork or artworks, I create the composition that I will use for the final painting. I often make a focus on a detail of a painting, and sometimes combine several images in a grid layout.
Step 3: The dialogs The dialogs and dates are accurate and based on my research. I use quotes or interviews of the artists that I include in the dialogs. My goal is to show the links between the artist and his friends, art dealors, collectors or lover... I try to be as close as possible to the personality of the artist and convey his message in just a few words. Hashtags and emojis are helpful to translate the story into social media language.
Step 4: Studio time ! To create the image part of the POST, I use acrylic paint. It's fun to recreate artworks painted in oils, encaustic, pastels or gold leaf with this medium.
One of my challenges is to pick the right colors because photos modify them. I study several sources to assess them as best as I can. That's why I take lots of photos when I go to a museum!
I print the original image at the same size than the finish painting, to get all the details. My background in photorealism helps me to reach the goal of painting what I see.
The text is printed direclty on the canvas to be as close as possible to a "real" Instagram.
Step 5: Varnishing Once I have taken photos of the finished artwork, I am ready to varnish the painting to give it a glossy touch and to preserve it. Then I simply have to write its title and ID number at the back and the painting is ready !
