I have a Nikon D5200, a standard DSLR camera. I just checked a photo in Photoshop by clicking "view in Browser" which brings up a window that looks at photos in given file folder on your computer. All the exif data is displayed in a column on the right. It took a little searching, but it looks like there is an indicator that says "Exposure Mode", on mine it said Auto on the first one and subsequently I did some bracketed exposures for HDR and the indicator changed to "Manual" so I think the info you are searching for is accessible in the data.
As far as enlarging, you can enlarge to any size you want, despite what anybody else says. I had an early DSLR, the Canon 5 megapixel D60, and I too came up with a "money shot" that people were buying. One customer wanted a large print to hang over his sofa, meaning like 48"x60" a real whopper! I used a special enlarging program called "Genuine Fractals", at the time it was like $100 and enlarged it to that size, the digital file was like 360 megbytes, I put in on a CD and took it to a commercial printer, who for a fee, at that time it was less than $100, made a print at the required size. I was amazed to find it perfect, no pixelation whatever. The customer was happy and I made a nice profit in the end.
As far as cropping goes, that is a judgement call, I almost aways do a little cropping to make a balanced composition, there may be an unwanted object on the side that can be removed that way, or too much sky can be fixed, or it you want to center the area of interest more. Just be sure to keep a high resolution setting on the cropping tool.
Tip for enlarging, (if you don't use a special enlarging program) try only 10% at a time. If it is 8x10, the first enlargement should only add .8 to the width, so make it 8.8 inches, then 9.6, 10.2 etc untill you get to the preferred size. I tried that and then compared to one I enlarged in one shot, and sure enough, when I zoomed in closely with the magnifying tool the 10% method did have superior detail.
The huge 24 megapixels the D5200 has makes superior cropping and enlarging possible even more so than a camera that has fewer megapixels.
