Hi 

 

would any experts have advice on creating bump maps of images for use in 3d renders? 

 

should I go the greyscale route or black and white ? is there a filter I'm not aware of? 

 

any suggestions most welcome.

 

thanks!

Hey there,

 

Here I am ;)

 

Greyscale 8 bit should be enough, saves memory. For displacements maps go 16 bit.

 

As for base color depends on your render engine. Some consider black as 0 bump, others 50% grey as no bump + in this case you have positive and negative bump(I would go 16 bit in this case just to get high quality gradients)

 

HSL, Levels, High Pass Filters are the quickest ways to get bump maps.
