Pure 3D.
Quite often we photograph elements where there isn't time to model or it just isn't possible in a realistic time frame compared to the comparative quality/time trade off from photography.
Having a fully CG scene can have many benefits; reusing items over and over again for example, as well as the time saved from compositing photographic elements properly. We have been using 3D scanners for 3-4 years now but this is our first go with photogrammetry.
We have been testing 2 photogrammetry options; Reality Capture and Agisoft Photoscan. Reality capture seems a lot quicker overall but won’t accept certain sets of photography if the exposure differs slightly. In those cases we've switched to Agisoft which seems to handle these cases better but takes a lot longer.
Below are the final images we created to test out the photogrammetry capabilities. Some fantastic work by one of our new recruits, creating the cheese and crackers. Other details were added by our more experiences 3D artists with a gentle retouch in Photoshop by our retouchers. Mistletoe model and fir sprig are from Turbosquid, here and here respectively.
Worth also mentioning that the Figs were scanned a few years ago using our old NextEngine scanner, did a pretty good job though.

Post.
A very small amount of post work was done on the images. The first image is the raw render, second is the photoshopped version.
Below is the AO pass showing the topology.
VRay SSS really helped bring the food to life, we also applied it to the mistletoe. In hindsight I think we may have overdone it on the Wensleydale SSS, it looks a bit waxy!
