Alas, the posted version is not the original file from the camera where we would be able to see the details of the EOS body and EF-S lens from the EXIF data. Can you post the original file rather than this Photoshop version?

Without the EXIF details, we can only assume the lens was focused on the woman in the center backrow. The image is so detailed, we can see the individual hairs on her face and inside her nose. We can see the individual facial hair of the woman next to her in glasses / Tigers logo and the partial head of the person obscured in the center of the frame. The "where" of this combo where the camera is focused is insanely sharp and detailed.

The location of the AF and the depth of field at f/5.6 are incorrect as needed to capture this entire group at the same level of sharp focus. My experience is to always focus on the nearest eye of the person nearest the camera, being the woman in light blue and glasses on our left of the image. Or maybe in this group, maybe the eyes of the child in the foreground. Still, f/5.6 is too wide to cover the entire group and 1/60 is likely too slow to reliable freeze the motion of this small group.

I mean "focus" via setting a specific AF point (or zone / group of AF points) to the specific location of focus. This is completely different from "focus and recompose". For event photography, this takes practice and skill and preparation. You won't get a good candid response if the subjects are sitting there waiting for you to configure the camera and focus. For this group, you need to look at their arrangement, decide the AF location and the exposure settings needed to capture them, and prepare the camera. Then raise, enable the AF and shoot / "cheers" all in one smooth and quick motion.

Program Auto lets the camera make an initial decision. Sometimes, the camera needs the 'help' of being told where to focus and it will determine a smaller aperture is needed for the composition. Otherwise, you have to tell the camera what to do, adjusting the Program-determined parameters or using another shooting mode. Manually setting the AF point to the child or the woman with glasses on the left is the primary change, then adjusting to probably f/9 would give the result you're likely looking for in this image, preferably also at 1/100 to assure the subject's small movements are frozen.

Finally, in your processing workflow, create your JPEGs in the sRGB colorspace, another change that will improve the shared / posted results.

Hi. I've used LR for about 10 years now. I've taught it at a local college as well as on a one-to-one basis and I have an LR website, viathelens.net. I recommend that you first go to the Adobe website and read portions of the online Help manual, in particular any part having to do with the Library Module. Do this prior to using the software. The Library Module is the heart of the software and learning it will help you to avoid problems and to use the software effectively. Know that LR does not store your images, you determine where they are stored and how they are organized. Second, once you link a folder to LR, you do this through the Import dialog, you must not change anything in that folder outside of the software as this will break the link. A third important thing is to read all of the boxes and settings in the software when you are importing, this is an area where people have problems. Do read up on the Library Module at Adobe. I like the Martin Evening book on LR, he knew the people who were involved in designing the software. The book is available as a download, too. To learn open a Catalog and use it as a practice catalog, using perhaps 10 or so images to work with. When you are done with it, delete the Catalog, this will not affect your images, and when ready open a new Catalog for your long-term use.
