So for a matte painting assignment. I was assigned to create a world that has a sci-fi feel. I decided I wanted to create an alien mushroom planet. Because This is a matte painting and it requires photo manipulation. So I went to Pexels and textures.com to mostly get the images that I required.
Then I went on to work on some simple thumbnails to work out the composition and some perspective. It doesn't have to be perfect at this point, just get the basic look and feel.
Then after putting together images in photoshop and editing the images to match the color and perspective. It was a lot of push and pull getting the composition and images to look just right. I didn't end up following the compositions I drew up in my thumbnails exactly and that's Ok. Its a process. Here is what I have so far.
This is a photo manipulation matte painting so I do not own the right to the photos
