I guess this is a JPG file, you do not have any RAW file.
Your camera has already done its best to make it not look right, but fit into the limited brightness range which can be shown in normal computer screens. Unfortunately the standard JPG generating process in the camera hasn't understood that not so perfect lens and image sensor spread diffuse light around high exposure areas and that makes the dark leaves look like they are in fog.
You can make a copy of the image in a new layer and apply different levels or curves to the copy so that the foggy areas are fixed. Then with layer mask you make just those areas visible in the differently adjusted layer.
Another way is to insert an adjustment layer. Here's a curves layer inserted and set to drop the brightness without changing contrast. A full black layer mask was inserted when the curve affected so that the fog was vanished and then white was painted with soft low opacity brush into the mask to the problem area:
Black in the layer mask keeps the effect off and white puts it on. Grey means partial effect. Painting white slowly gradually fades the effect in with no disturbing border.
Save as JPG flattens the image to single layer. Save as PSD retains the editability.
