InDesign makes black and white photos brightener than original

I'm using InDesign CS6 and I'm preparing a book there are black and white photos. When I want to export a .pdf file, these black and white photos are brighter than the original ones.

I can see this in InDesign when I check "Separation Preview": all CMYK (screen 1) gives brighter photos, K alone (screen 2) give the correct photo.

There is a lighter image in the exported .pdf file.

Please, what to do to ensure that the photos in the exported .pdf are properly saturated?

Thanks! What to do when the printing house asks not to include ICC profiles?


Export to a PDF/X preset with the Output Destination profile set to Document CMYK—that will convert all CMYK and Grayscale objects to DeviceCMYK and DeviceGray (no profiles). PDF/X will keep transparency live, PDF/X-1a will flatten transparency

The difference in the appearance of black and white photos in .pdf is due to the simulation profile?

After clicking "Output Preview":

 

In fact, I do not understand why now some photos are exported to me as they are in PS, and others not ...

 

Where do these problems with the saturation differences between imported and exported black and white photos come from?
