alpha image

[chipster]

hello folks
im in need of some help,im a total newbie to photoshop and im trying to make my images look like this in the first image,i believe you call it an alpha,
im not sure what sofware it was created in(could be artcam) but its my understanding that photoshop can do the same.
as a hobby i run a cnc router i built several years back and used to have a software that converted a jpeg or bitmap in the same way but at the click of the mouse,so ive not concerned myself with how its done until now:redface:.
can anyone point me to a tutorial that will step by step tkae me from importing a photo or image and turning it into what you see in the first image then i can export it to a 3d modeling software like z brush etc ready for machineing,thanks

well you could just openup the chanels window (tab next to Layers) any 1 you click on apart from RGB will give you similar results

Sorry about that chipster, the system automatically moderates some posts on it's own based on keywords.

Not the PSG system, steve. The link works but the video at mimeo won't play at the time . Now it plays.

Height map for complex rotated objects (like a horse) can't be made in Photoshop.
