Make a list of things Jesus created that need to be photographed, perhaps giving a different point value for each item photographed.
Have fun coming up with the list to start with, then go on a walk or drive and see if you can get a certain number of points.
An example of things to photograph could include concepts like these:
A person with a picture of a flower on their top, two ducks together, a cloud that looks like an animal, a white feather, a cross, a musical instrument, a heart shape, animals starting with each vowel, falling water, three or more fruits together, a picture of Jesus, a Bible (or the word), a purple flower, wind (or its effects), etc
