Hopefully you will find the EV meta data will have been found and set, if not you will need to manually set the EV value but putting in a number or by adjusting the slider.

Click on ether the drop down box or the tab (depending on version and os) and select “Mantiuk”,
Leave all settings at default except for size and pick on “1024X768” and click on “Apply”.

After a wait (length depends on pc specs) the tone map image will be generated using the “Mantiuk” routine.
Click on “ Save as ...”, name the file (don't forget to put the .jpg on the end).
Then click on “Exit” to close the Tonemap Wizard then click on “Exit” to close QTPFSGUI.

Sit back and give yourself a pat on the back for creating your first HDR image from a jpg.
