Thanks a lot, this seems to be working!

Actually I'm using Magick.NET library (https://github.com/dlemstra/Magick.NET) to perform such conversion within .NET application. How can I translate with script to .NET code?

Well, thanks, indeed it is. After executing this command output tiff contains 2 images, like you describe. But that's not what I need. I don't need multipage tiff, but instead I need one page tiff with alpha as separate channel in open in Photoshop. Can I achieve this using ImageMagick?

Thanks for response. But is there a way to make this one alpha channel to look in Photoshop as separated channel, not merged into CMYK channels?
And will multiple alpha channels will be supported in the future?

Hi All,

I have some input.psd file containing 2 alpha channels within it. This is how it looks when open in Photoshop

It has 2 alpha channels - Spot1 and Spot2

I use the following command to covert it to tiff:
