Playing with Different File Formats

This is a shot of 40th and Park AvenueI took in 1992 at 12:17am on a Saturday morning. Here I saved it as a 24bit PNG image. Here is a link to the same image saved as a JPEG File. (Notice how different it is vs. a Rainslicked street?) It has the same resolution, but IMO the PNG file looks better but they are probably equal quality.
