In this collage, I combined 3 monochromatic images using Snapseed's "Double Exposure tool". It's a free photo editing app which is almost similar to the professional version of Photoshop.
After combining the 3 images, I used Snapseed's "Retrolux tool" to colorize the resulting image.
From there, I tweak result by adding glows and contrast to achieve a cartoon looking art.
And then I finished the photo-art by adding Text. That's it! It's a fun way of creating a new image using existing images. Here's the final result.
I love taking photos of anything and I like to turn it to black & white image. It is for a simple reason that the picture becomes pure, free from color preferences. With black & white, you interpret the meaning of the photo and not the colors.
