To take great close up pictures with detail you need a 60mm F/2 macro lens use an f stop of f14 to f16. Otherwise with a standard 50mm lens increase your f stop to increase the depth of field to like f 14 1/60 shutter speed and use a flash and an iso setting of 200. Set your image size to like 3500 and then crop the part of the image you want to show in detail. You will loose detail if you re-size images.
This is the result-----

The picture below I resized and you can see you lose some of the detail-----just experiment film is cheap!!
