Also, while you could shoot very small stacks handheld, it’s going to be much more difficult. Each frame needs to be as consistent as possible, other than the focus point, and exposure changes can cause issues. The next is that if you’re shooting the stack by hand (not advised), make sure to lock in your exposure on the first frame.
That stack is ruined, and you might not know until you get back to the computer, so err on the side of too small a movement, compared to too large. If you move the focus beyond the point where the two frames have the in-focus areas overlapping, you’ll end up with a subject that has alternating bands of focus and blurred areas. The first is that you can’t take too big of a step between each frame.
There are a few things to keep in mind when shooting, regardless of which method you choose to capture the frames. Note that depth of field doesn't extend across the whole flower, even stopped down to f/8. Here's an example of a single frame that would go into a stack. If you’re going to try again or shoot a similar composition, I like to take a random picture of the ground just to separate the different stacks in Lightroom. Continue to move the focus point back and take photos at each point, until you’ve reached the farthest back point you want in focus. Ideally, you’ll just be shifting the in-focus area back, not changing it entirely. From here, trigger the shutter, then move the focus point back ever so slightly. The basic setup goes: choose an exposure and set it manually, disable adjustments like auto ISO, and move focus to the nearest point in your image that you want to be in focus. This set of exposures then contains a wider cumulative area of focus compared to even a significantly stopped down single photo, and these shots can then be combined in software to produce a final image.

Fortunately, it’s easier than ever to properly focus stack. When you don’t have to worry about stopping down or picking what’s in focus, you can be even more creative. Focus stacking, where you combine multiple exposures at different focus points, can completely change the game when it comes to tricky depth of field situations. Whether you’re shooting macro subjects like jewelry and flowers or landscapes on the latest high-resolution bodies, controlling depth of field can be essential.
