Does MP works only with 24bits TIFs?

[AAM]

Hi,

Is this a normal behaviour?

1. I opened in MP a 48bits TIF.
2. I adjusted the TIF using the Luminosity curve and I save the image.
3. The image got converted into 24bits.

What am I making wrong? Does Xn View MP can only save the files up to 24 bits?

Thank you.

Component of pixel are always converted in 8bits, if you want to keep 16bits per component only NConvert can do the conversion
