I have a single JPG file. If I open it with IrfanView, it is darker than the same file opened in PhotoShop (or in Firefox). What can cause this? The correct version is the one from Photoshop (or Firefox). I have also tried to open it manually with LibJPG-Turbo in C++ app, but the result is same as Irfan - dark.
Left: Irfan
Right: Firefox or Photoshop
From exif info tool, I have obtained also this:
