After 3yrs of reading books looking at videos and shooting with my camera I am having a brain block about camera setting, It just doesn't sink in, I'm so frustrated.
I'll make a few assumptions. I'll assume that your post is serious. I also assume that you are not referring to problems with the image quality you are getting (sharpness, exposure, noise, etc). I also assume that after 3 years of "studying" you have a basic knowledge of shutter speed, aperture and ISO settings - what they do and why they are important (if you don't, you are not ready to use the camera in anything other than the fully automatic modes!).
So I'll assume you know the basics (the "exposure triangle") and that your problem is deciding which of the D5600 shooting modes (Auto, M, P, A, S, scene modes, etc) you should use. Reminds me of being on the Charles Bridge in Prague with my new D5300 camera and, even after having read the manual, being essentially clueless on how to set up the camera to capture the beautiful sights before me.....
I'm going to suggest something that will make some of our UHH friends gag, yell and boo: Try setting your D5600 to "M" on the dial (Manual) and turning on "Auto ISO" in the menus. With this semi-automatic setting, you select the shutter speed (based on your need to stop fast action and/or minimize camera shake) and aperture (based on your desire to control depth of field). The camera then selects an ISO value to give you the "correct exposure".
I think that this shooting mode, M + Auto ISO, is a great way to shoot and also to learn. You will learn, for example that depending on your shutter and aperture settings, you can get over or under exposures because the camera has a limited ISO range. In that case you have to change your shutter and/or aperture setting. You will also learn how you feel about noise and other effects of shooting at high ISO values.
If you go that route, M + Auto ISO, like shooting in any semi-auto mode, at times you have to add another setting - "Exposure Compensation". You can select that on the Information Screen of your camera.
So, I suggest you try M + Auto ISO + Exposure Compensation (when needed). Good luck!
