I am new to this, so forgive my ignorance. But I am basically copying his settings just to play around with it, and I see the -5.0 at the bottom, and that slider can't be adjusted. What setting is that for?
That is your 'Exposure' and is there for reference and can't be controlled directly. You would have to adjust the shutter speed and/or ISO sensitivity to get the Exposure correct (0). In the picture the (-5) means it's 'underexposed' and will result in a darker image then what the camera defines the scene should be in order to be properly exposed, a balance between darkness & brightness is (0). So in this case you would want to slow down your shutter speed (lower the number) and/or raise your ISO sensitivity (higher number) to find a balance where the Exposure number is (0) or as you prefer.. because in some cases a person may choose to underexpose or overexpose an image intentionally for 'artistic' reasons.
Keep in mind though - a low ISO is always preferred and results in a cleaner image, less noise - Used in bright environments. Raise this number to have the camera's sensor be more sensitive to light, but keep in mind the higher you go the more you'll deal with a 'depreciated' image. The first thing you would want to adjust is lower (or raise if the exposure reads +#) the shutter speed, so that light has more time to enter the camera and 'expose' the image more. Find a happy balance to get the exposure meter to (0) or intentionally over/under if that is what is wanted.
One last thing to keep in mind when you shoot video (not photo's). The shutter speed should be double or a factor of itself relative to the framerate you are shooting in (24, 30, ..)
So if I'm shooting 4k at 24 fps (framerate-frames per second) I would want my shutter speed to ideally be at 50 (1/50 of a second.) This will produce 'smoother' footage, it will look proper. Otherwise it will look weird. For 30 fps, a shutter speed of 30, 60, 90.
I don't have any examples off hand, but if you watch a bunch of Mavic footage on youtube and you keep an eye on the background of a shot, like mountains in the distance and you'll sometimes see 'juddering' where the video looks like it's skipping frames. Not smooooth.
I hope this helps!
And if someone can enlighten me as to why in the DJI Go camera settings Exposure is labled as M.M (something Metering?)
Edit:
I wanted to add & this doesn't apply to the Mavic, Air, etc. but lot's of camera's have a way to adjust the aperature too, the opening and closing size of the lense 'hole' (for lack of a better description) to let in more or less light. So in those cases you would find a balance between your Shutterspeed (speed of the opening), Aperature size (size of the opening) & ISO (Light sensitivity) to expose the image properly.
And sorry if I've drifted into territory that may already be of your knowledge, figured this would be helpful to some. And maybe I should have just started a new thread with this subject.
