My inspirations came from Adan Matrin & Bertrand Benoit 

Now to my steps of making a realistic food (Mango) from PHOTOGRAMMETRY  

I Learned Agisoft Photoscan & it was easy to learn from YouTube &i used my Canon EOS 1200D​​​​​​​ for taking 57 images of a Mango i bought .. (i made it a Mango juice after..yummy)

first i made 3 chunks for top and bottom & middle of Mango shots.

 i made the Tie points then Dense Cloud for all chunks..then generate a model from Dense cloud of merged chunks.

Then exported the model as obj to retopology it in 3Dsmax as lower poly 

(obj was 1.9 Million).

the tricky part i made in retopology for this easy surfaces is that i made a sphere & refine it with FFD modifier to make nearly shape of the Mango then work with Freeform & use conform to make all polygons touch the surface of the high res. Mango. was so easy & fast. i made it to a Lemon too and worked great.

export the low poly & opened UVLayout for Unwrapping.. love this software & so easy to use. 

Back to Agisoft Photoscan to apply Diffuse texture to my fine UV model (you should choose "keep UV" option in this step.

Final step in Agisoft is to export the texture in 4K.

Now we open Susbtance Designer to make the Normal & Displacement map.

Adan Martin have a great tutorial on that so i can skip this step.

just mention that i get bad texture result with dis. map so i didn't use it.

i use the diffuse to make reflection map.

i Work with my Lovely render .. Corona

i make tests with material and got this realistic material like the Mango on my desk.

Finally i use Mass FX and make a nice plate of mango.. (the plate is not mine).

i used DOF in 2nd image & i used PS for make the image as it was taken by a food photographer.. LOL

here is the images that get right away from render

Hope you liked it and learn something from my long talking. :)
