As we were driving one evening after sunset, I snapped a photo. Since we'd recently been to the Monterey Bay Aquarium, my mind went to the jellies and how one of them could be used to mimic an explosion in the sky over the freeway. And voila, an image is born!
I started with this photo I took with my iPhone in a car on highway 101, towards home.
And I also used this image from my iPhone 7 Plus, taken in the Monterey Bay Aquarium, using ProCamera on slow shutter.
In iColorama, I applied Adjust/Tonelab preset 4 at medium opacity for clarity and depth.
Using Effect/Blend, I blended these two images in overlay blending mode, using my fingers to resize the jellyfish image to place it where I wanted it. I chose this blending mode because it created that lovely pink horizon, but it dulled the jellyfish.
Next, using Effect/Blend, I blended the Tonelab'ed jellyfish with the above image, this time using Normal blending mode, and using an inverted brush mask to paint back the jellyfish image only over the jellyfish, to bring back its original brightness.
I used Form/Warp to straighten the transition to black at the bottom of the image, and then I cropped.
Now in Effect/Blend, I blended in another image for texture, at low opacity. I tried several different blending modes.
This is the image I blended in for texture. The base image was a Pixabay (a source of copyright-free images) image of an elephant. I painted over it in Metabrush using many different brushes, mostly doodle brushes. Then I blended the Metabrush image with the original elephant image. When I blended this with the jellyfish/highway image, I enlarged the elephant and placed it so that I was using mostly the upper right part of the elephant image.
Here is the Pixabay image of the elephant.
I applied Effect/Light preset 70/83 at medium opacity, and using a brush mask on the lower portions of the image so the effect would not apply there. This Effect/Light preset is what created those interesting effects in the sky.
I used Adjust/High preset 1 (masking out the bright parts of the jellyfish), Adjust High 2, Effect/Glow, Effect/Sharpen preset 3, and Effect Raise preset 2, most at low opacity, for the final image.
