EOS Utility doesn't show exposure meter in manual model. In manual i usually adjust the exposure by stopping up and down. You cant adjust this on manual. It lets you adjust in AV and TV but not manual. How is this adjusted in the Utility? There has to be a way.
I just did a bit of Googleing and found this thread
Lifted from the thread:
These is no real use for the exposure compensation display in manual mode via the EOS utility. The cam decides the relevant aspect(aperture / shutter speed) to change in TV and AV modes - where as in full manual mode the utility is probably expecting you to alter this based on say a light reading / or other method to decide exposure.
If you were to use this exposure compensation display in full manual mode you would have to interpret how to adjust the shutter or aperture yourself according to the bar - not as accurate as other means. It would be far easier to take a shot with AV / TV mode, note the settings and move to manual mode or as suggested in the thread you could use live view / histogram to check for correct exposure.
Another suggestion would be to use a light meter to get the correct exposure for your shot.
