Hello @zakir43

About your smartphone, I guess you can use it as "Any Medium or Format is allowed". After this sentence, it is just examples.

About the Basic processing, it means you can use a software as Lightroom (or similar). You can by example play with the exposition, the lights, the constrat but you can not use a software as Photoshop in order to modify your photography.

I hope it will help you to participate to the contest !

Good luck !
