I notice that people often post old Apollo era shots of Earth, unprocessed, in some cases reproduced from faded prints.
Well, haze in the atmosphere dulls down all shots from space, but it’s REALLY easy to fix. I’ll be using Photoshop elements, but you can do the same with pretty much any image editor, including the free open source GIMP. Similar options are available on tablets and phones.
The same techniques are a good start in restoring scans of old family photos.
I wanted to make a dwarf planet, using elevation maps from the Moon, (and maybe Mars?) for realistic craters. I thought it may be helpful to save out the steps, so that others can follow along. Tutorial time!
You will need:
The 3D program of your choice, it should support displacement maps.
A high res source elevation map, these are available online.
An image editor that can edit 16 bit grey scale images.
I started with a slice of elevation map from the rear of the moon, (less recognisable), in the proportions of 2:1
