You will not get the same result at all. When you start with your 2000x2000 pixel image you have some scene or subject in it. If you crop it down to 500x500 pixels then you will only have 1/16th of the subject in it. However if you have a 500x500 with the same but lower resolution content, you will have an entire subject. What you can do instead is scale ...

Pixels will be 1/28 inch wide, or 0.9 mm. Now you have to decide whether that's good enough. To decide that, print out something at 28 DPI and see how far ...

Try Dehaze in LR or ACR. If that does not work for you, try experimenting with vibrancy/warmer white balance/clarity applied gradually over the area with the haze. The tool names probably differ in non-Adobe products...

This is very easily done in Post Processing, I'll do it using Photoshop. I did it with 3 adjustment layers which I'll explain. First I did a Color Fill with Blend Mode set to fill using a bronze color. I then adjusted the Blend-If Lightness, Underlying Layer to 0/231, 50/255 Then I did a Contrast Curve on the Lightness pulling the midtones down and ...
