I painted this landscape in Paintstorm Studio Pro by first painting in blocks of color, painting over a photograph of mine. Then I painted a layer of textured foliage, then a layer of sky, then a layer of textured rock, and then I combined the layers. I finished the image in iColorama, where I worked on color, tone and relief.
I started with this photo of mine taken in Acadia National Park, enhanced in Lightroom.
I opened the photo in Paintstorm. I've been having memory problems using Paintstorm because I was using a canvas size of 4000 on the long edge. So in Paintstorm, I resized the photo to 3000 on the long edge, using Image/Canvas Resize. Then, on a new layer, I painted with the Roller 2 brush. In the brush settings, I checked Take Underlayer Color, I made sure Dirty was unchecked, and I set Color Amount to under 10%. This way, when you paint, the Brush will pick up color from the layer beneath it, rather than from the color picker. I noticed later that I had the image zoomed in and didn't see that I had failed to paint the rightmost edge. I'll deal with this later with a crop. The image I show here has the opacity for the photo layer turned off, to show you only the paint layer.
I moved the painted layer to the bottom, under the photo. I created another new layer above the photo. With a flat texture brush, I painted the foliage. Using Image/Color Balance & Brightness, I increased the contrast of the layer and deepened its colors. Again, I failed to zoom out to notice that I hadn't painted some of the right side. I'll notice this later and come back to this layer to paint more. While I didn't do this, I think it would be a good idea to rename each layer as you create it with the name of the brush you will be using. This would have helped me when I came back to finish this layer. The image I show here has the opacity for the photo layer turned off, to show you only the paint layers.
I used a variety of brushes to paint a sky layer.
On a layer underneath the foliage layer, I repainted the rock with the Oil with Canvas Texture brush. I finished painting the foliage on its layer, and also painted sky on the foliage layer.
I changed the layer blending modes and reordered the layers. On top is the sky and foliage layer in Soft Light blend mode. I put the foliage layer on top because I didn't want to obscure any of its strokes with other painted layers. Underneath that is another sky layer in Normal blend mode. Underneath that is the rock layer in Soft Light blend mode. I used Soft Light mode so that I would get a blend of the original painted layer and the repainted rock layer. Underneath that is the full-canvas color layer I painted first, in Normal blend mode. Underneath that is the photo, with its visibility turned off. I saved to my camera roll. I also saved a psd file to iCloud, in case I might one day want to revisit the file with all its layers. You'll notice that turning off visibility of the photo layer left me with some white unpainted spots. I'll deal with that in iColorama.
I opened the image in iColorama and cropped.
Using Effect/Blur, I blurred the image, and saved but did not apply. I used one of the Blur presets that gives some texture in the blur. Then using Effect/Blend, I blended the blurred image over the unblurred one. I brought up the brush mask bar, touched Invert to create an inverted brush mask, and with a very small brush, I painted a spot of blur over each of the areas of white canvas.
I used Adjust/Tonelab preset 4 at low opacity for tonal separation. I used some presets in Tone/enhance at low opacity as well as Adjust/Channels Preset 1 to correct and intensify the color. I used Adjust/High preset 1 and Effect/Light to bring out the highlights. I used Effect/Raise to enhance the relief and bring out the strokes. I used Form/Warp as well as the Elasticam app to drag some unwanted bits off the edges of the canvas.
