A great start!
Mary you're adventurous. Suggestions. You are the guardian of M&M, our mascot, so I have to help you!
Move around so that sky or grass shows through the leaves, not the brick wall. If you turn your flash on, that will help, also it will be easier to get a sharp shot hand held. Put one thin layer of toilet tissue or a thin piece of nylon stocking in front of the flash with a rubber band to really make the light soft.
Buy a Macro lens from B&H

Call them and tell them what your camera is and that you want a 250 D macro filter.
I'm not sure if you need an adapter.
Someone else chime in here, please.
You could also return to your local camera store and they might have the stuff in stock.
Let's see if we can get more exact spec ifications.
Any way, this will get you closer to the berries and they will take up more of the frame of the picture.
This way, more pixels will be devoted to them and the image will be sharp.
Try to rest the camera on someting to krrp it steady: the back of a chair, a little step ladder, or another tree. You can brace yourself against a wall, tree or post to keep you still. Hold your breath when you gently release the shutter. So gently!
Then you will have a really sharp picture with a great background.
That's enough for now.
Good luck,
Asher
