Particleshop- How to Convert Files to 8-bit RGB?

[PeytonJacob]

Please can someone help me to convert photos into 8-bit RGB in order to edit in particleshop? Every time I try to open a photo it comes up with an error message saying 'TIFF file has an unsupported number of bits per sample' and the Aftershot online manual said that particleshop only accepts 8-bit RGB?

I don't really understand what 8 bit RGB is properly but there's no option to export the file as that type in the software so I don't know how I'm supposed to convert it to the required file type?

Corel technical help has been looking into this and even did a remote desktop session tonight with me and they couldn't find it either so I'm stumped. It's now been escalated to the next level of support.

Any help would be much appreciated if someone knows how to do this.

Thanks
