Irfanview image viewer - colour management

[pinup tragic]

Hi all, it seems that irfanview is off kilter or maybe i never fully noticed but there is a massive difference between the image viewer and photoshop on B/W images / scans - screenshot is not colour managed but you can see the difference - 35mm scan - Hasselblad Grey...Irfanview is colour managed according to my settings - use monitor profile
