What the DJI Go Settings Mean:
ISO—ISO measures the sensitivity of an image sensor. The
sensor in the Phantom is very small and delicate, and I would
not suggest ever going above an ISO of 400. Anything more
and your image will look grainy, muddy, and unappealing. You
can go higher if you choose, but be aware that the images
won’t look as nice as they would otherwise.
Shutter Speed —Shutter speed measures how long your shutter is open. The higher the number, the faster the shutter snaps
and the crisper your photo will appear. There is no ideal shutter
speed, but my general rule of thumb is that the higher you can
set it while maintaining a bright image, the better. If you are
shooting photos, this is even less of a concern. I try to keep my
shutter speed above 200 just to play it safe, but I have gone far
lower and still produced nice, crisp images.
EV (Exposure Value)—EV lets you compensate for the relationship between the shutter speed and the ISO. Anything on
the plus side of the spectrum will brighten up the image and on
the negative side will darken it. I try to get a nice balance without messing with the EV all that much.
