We are still in Russia. This is a canal in St. Petersburg. It was a dull overcast day.
Your Challenge is to convert the dull day into a bright colorful image.

If you rush to the Haze Removal tool watch out for halos appearing on the edge of buildings and roofs. Pull back on the slider or use a different adjustment tool.

The lower sky is white, do not allow this area to burn out to bright white with no detail. Do not replace the sky. Improve it. Watchout for noise.

The houses are very colorful, bring out the colors to add impact to the image.

Crop if required.

Context: sell St. Petersburg as a travel destination.

Sorry no RAW file. You'll do fine with the png file.

Gave it a little try Shakey.
I see some members are interested in how we do some things so I will mention a few. All my edits were in Photoshop. I broke this picture up into 3 primary layers all having their own mask. First one is for the buildings. I used camera raw and decreased highlights, opened shadows, increased whites, increased clarity and saturation. Layer is a duplicate of the improved first layer then reduced saturation and blue. The sky was also a duplicate of layer one and increased whites more, lowered highlights. Added a color correction layer for the sky and increased blue. Sky was not bright enough and couldn't get it so it didn't look so overcast so I added another layer set it for screen and dialed it back for just a slight improvement in whites.
