Don't know how to take close-ups of objects.

Don't go too close to the object, since the lense works similar to the eye. EX if you put something mm. away from the eye it appears blurry and hard to see.
You need a certain distance and then use the zoom untill you have the desired image.
In SCN there is a special option for close up pics.

Pls. rate me good if any of these tricks have been useful for you.
Good luck

I used the above solution and it worked. I did not zoom in too much, as the more zoom I used the photo became slightly fuzzier. I used the Program/micro focus.

If you are like me and want to fill a picture with a flower, you'll have to go back and edit down the photo after.
