batch grayscale conversion?

[astropixel]

I need to batch convert RGB to grayscale. I know that Juan wrote a batch grayscale converter for the batch debayer script about 3 years ago. How would I go about isolating that part of code and using it as a stand-alone script.

Secondly, a PixelMath conversion should work - but how is that done. I reread Juan's old post and cant get it to work. Not my strong point.

Perhaps I have missed something obvious? Format hints when using the batch conversion script - maybe? Not sure?

Hi Rowland,

You can use ImageContainer with a ConvertToGrayscale icon. Just select your disk files on IC and drag the IC triangle to the CTG icon.

Thanks Juan. Easier than I thought.!
