For one thing, you need to take the picture with the camera on something thats not moving (like a desk) as well as the bud. The way I do it is I take my cam, set it on my desk, take a pic of my bud on something that elevates it to where the camera is focused (my digi scale works perfectly). Another important thing to do is to give it a background(I use a folded sheet of white paper), this allows the camera to have a more even plane of focus, and focusing on your buds will be more likely. Also you'll want a flat surface of buds facing the camera so more of them will be in focus and it looks nicer. So now we have the cam, in macro mode, facing the elevated weed, with a background, set your light setting on the cam to match what you're using (don't use flash) and whatever you use, (mine is a bright desk fluorescent energy saver) have it close to the bud to illuminate the bud and trichs.
After typing this, I demand pics
