There are two types of zebra which accounts for the difficulty you mention. It can only be resolved from a photo if you revert using B&W. Border Collies exhibit the same difficulty. The ones South of Hadrian's Wall(English) are white dogs with areas of black and those North of the Wall( Scottish) are the reverse.
Yes I know that Hadrian's Wall no longer demarcates the border but no-one told the collies.
However for a colour photo of a B&W zebra I have to say this is very good
I had a tricolored Border Collier [tan, black and white] when I grew up.
Warning!! Handling a Hasselblad can be harmful to your financial well being!
Nothing beats a great piece of glass!
I leave the digital work for the urologists and proctologists.
