Do about what?
Picture shown, has the sun in shot, over exposed cos its bright.. and beach in foreground a tad dark, 'so its not emitting or reflecting a lot of light.
What do you want to achieve?
In camera light meter has probably averaged the brightness of the whole scene, ie bright sun, and dim shore and come up with some sort of 'average' to cover the range as best it can, and the results are what you see.
If you want to dim down the sun.. that would beg diming down the whole shot, which would darken the foreshore more. Conversely, to brighten up the foreshore, you would up the exposure over the whole shot, which would brighten the shore but blow the sun out a bit more.
This is how cameras work, and you could get more elaborate on the metering, but the answer would be the same, you have a tonal range in the scene wider than the camera can capture... so you have to pick settings to get what's most important, exposed to your taste as best suits.
You could try holding back the sky and sun with a graduated filter, to dim the top portion of the frame... but you could get the fade line wrong, and its only going to fudge the mater a bit, underlying tonal range remains,or you could get technical and take multiple exposures, one for the bright spot (hi-lights) one for the mid-tones and one for the shadows, and merge them in post process, (HDR or High Dynamic Range' manipulation,,, an old technique employed by masters of old with very low dynamic range glass plates, brought up to date with a computator!).. But, the underlying issue remains, you have a very bright sun in shot and a shaddowed foreground,,,, try a different time of day.... and/or mess with various exposure methods, metering means, and as much paraphernalia by way of grads or multi-image merges as you like really.,.
Back to top.... What would we do about what? And what do you want to achieve?
