are you using manual settings?
I do have a question. How to balance aperture and shutter speed?
using aperture priority or shutter priority, you can only control one or the other following the name of the mode. the other value will be determined by the camera's metering for exposure. you can then adjust how 'bright' or how 'dark' the picture is by adjusting the exposure compensation; which is the << -[----0-|---]+ >> bar... negative for darker image, positive for brighter image.
if you're using manual mode, then you will need to know whether your priority is shutter speed or aperture. once you know for example, you want a shallow depth of field, you open up your aperture let's say, to f/3.5, then now, adjust your shutter speed to get the moving bar in << -[----0----]+ >> to zero. that's where the exposure is optimum as 'read' by the camera's metering. from here, adjust to taste. same goes if you want a specific shutter speed, then you adjust the aperture to taste (and probably ISO too if you're maxing out on the aperture)
hope this helps. else, read up on photography's exposure 101 (light trinity - aperture, shutter speed, ISO) on how they affect one another. that will make your photography journey more meaningful.
