Photographers, from left to right: Aljieryon Hill, Aljieryon Hill, Ifetayo Forrest, Andy Vasquez

Post your corrected versions of all four to Flickr.

Select your favorite of your partner’s photos that could look better with some adjustment. Tone it in Lightroom. Your partner will also adjust the same photo. Compare your results. Post both versions titled with each of your names to openlab using a gallery so we can see them side by side.

Now, reverse it. Your partner picks their favorite of your photos. And you both adjust it. Post the results.
