Using Metabrush to create textures, along with the blending tools in iColorama, an infinite variety is possible started with the same image. Here I started with a sketch of mine, painted it in Painstorm Studio, and then produced three very different version using Metabrush and iColorama. In each version, it is all about the texture.
I started with this 90-second sketch of mine, drawn from a live model.
I photographed the sketch and opened it in iColorama. I cleaned it up using Effect/Levels (to lighten the image) and Style/Simplify (to get rid of the paper texture). I used Brushes/Clone to clean up the lines. I used the Elasticam app to change the shape of some of her features, most notably her right hand.
I opened the image in iColorama. I used the last preset under Style/Water at medium opacity to produce this image. I saved this image to use later. Call this Image A. We will set it aside for now.
Now I opened my sketch in Paintstorm Studio, and on a new layer I painted with the watercolor brush.
I moved the sketch layer to the top of the layer stack and changed its blend mode to Multiply. This is so the watercolor paint does not obscure the lines, and so we can see through the otherwise opaque white background of the imported sketch.
I added a new layer and used the paint bucket tool to fill it with color. Then I dragged the layer to the bottom of the layer stack, so that it does not obscure the image elements on the other layers.
I opened the image in MetaBrush and on a new layer, I painted with a lot of different Brushes modes.
Now on another new layer, I painted in Brushes/Paint mode over the figure. As secondary image, I used the image itself. (While in Brushes/Paint, to choose the secondary image, touch the flower icon on the left edge of the screen and select an image from your camera roll.) I painted with a variety of Kanji and Petro brushes. In brush settings, I set spacing to its maximum value, I set position variance and rotation variance to their maximum values, and I left dynamics at their default values, I set shadow to zero and structure to its maximum value. I saved to my camera roll.
I opened the image in iColorama. Using Effect/Blend, I blended the previously saved Image A onto it. I tried several blend modes and slider settings, including the sliders under Set.
I used Effect/Raise to emphasize the strokes.
I blended Image A onto the image again. I tried several blend modes and slider settings, including the sliders under Set.
I used Adjust/Tonelab and Tone/Enhance to improve tone and color.
I applied two different presets in Preset/Border, using a brush mask to protect the head and feet.
I increased exposure using Adjust/Exposure, and I used an inverted brush mask to paint the increased exposure as highlights.
I used Tone/Pastels and Adjust/Levels to Adjust color and contrast. This is Version 1.
I used Effect/Blend to blend Image A onto the image again. I tried several blend modes and slider settings, including the sliders under Set. Then I used Effect/Raise to bring out the texture. This is Version 2.
I opened Version 1 in MetaBrush and painted with a variety of brushes in Wets and Brushes. These are a few of the layers I created. I experimented with changing the layer order and opacities. I used the Erase tool to erase from some of the layers where there were bits in the final combination that I didn't like. I saved the final result to my camera roll.
I opened the image in iColorama and used Adjust/EQ to adjust tone and color.
I used Effect/Blend to emphasize the texture. I used the Elasticam app to change the thickness of her right arm.
I used Form/Crop to crop some of the edges. I used Effect/Blend several times to blend the image onto itself, with an offset, and using an inverted brush mask to paint in some areas that I felt needed altering, around the face, right shoulder, and feet. I used Tone/Duotone to alter the tone of the shadows, and I used Tone/Pastel to alter the tone of the highlights. This is Version 3.
