The process behind it all: Below, you see my Adobe Photoshop CC 2018 workspace. This is the first essential part of my "madness". For this double exposure piece, I used several pieces from Adobe Stock but before licensing, I downloaded the basic "trial run" of the images to makes sure they fit cohesively and made some basic minor adjustments. If I liked the trial run, I pursued further with the official Adobe Stock licensed material to make something completely new. This is my brainstorming process.
All images were officially licensed on Adobe Stock used for modify use in double exposure purpose solely. Copyright: svetlanamiku | Vladamua licensed images off of Adobe Stock.
