About the later period of photos, how to make photos transparent and clear?

The final photo should be transparent, which is related to the later stage, and the early stage is more important. For example, the current weather, smog like milk, visibility is very low. When you open the door, you can't even see the face of the person next door. For the photos taken under this condition, please fix the transparency for me. Obviously this is unrealistic, not to mention that too much later will affect the picture quality.

Good light in the early stage, easy to retouch in the later stage. Basically, you can make photos more transparent through contrast, color scale and curve. Here is a chestnut: for example, before a sunny morning 10, the sun was shining and the visibility was quite good, with a reed flower in the background. As long as the exposure is accurate, the original film will be more transparent and make your eyes shine. Reed flowers are almost transparent and can brighten your titanium alloy eyes. That's why you don't usually choose the time and pay much attention to the shooting angle. When you see something, the shutter rings, and finally you complain that all the photos you take are gray.

Having said that, the importance of the early stage is so strong that the later stage can only be icing on the cake. If it's out of thin air, it's not photography, it's not retouching, it's pure PS.
