Design me an eye-catching cover that looks great when it is minimized as a Amazon thumbnail and also looks stunning when it is displayed as greyscale on a Kindle. The image should be future focused with strong Science Fiction feel.
I had two ideas, feel free to go with either of these two options:
1. Lunar Landscapes
The story is about a helium mining base on the Moon so the image must feature a lunar landscape or dark mining scene. I'm looking for gritty realism with a heavy industrial feel. Think about big mining machines and hostile environments.
2. Underground Living
Much of the story takes place in hollowed out mines in the hills of Mare Imbrium. Here are two images of underground life that will give you an idea.
Kindle Direct Publishing currently accepts two types of files for cover images:
JPEG (JPEG / JPG)
TIFF (TIF / TIFF)
For best results, please upload your images with minimal compression.
The ideal size of your submission is a height/width ratio of 1.6:1. In pixels, this means that, for every 1,000 pixels in width, the image should be 1,600 pixels in height. To ensure the best quality for your image, particularly on high definition devices, the height of the image should be at least 2,500 pixels.
Ideal dimensions for cover files are 2,560 x 1,600.
Important: The minimum image size allowed is 1,000 x 625 pixels. The maximum image size allowed is 10,000 x 10,000 pixels and your image must be less than 50M.
Your image must be less than 50MB. Try to avoid compressing your files, as this can affect the quality of your cover when displayed on reading devices. Be sure to save your file with 72 dots per inch (DPI).
