![]() We have a great article here for how to get sharp photos, which can help with each individual shot for this series. We don’t want the composition to change as we’ll be layering the images on top of each other in Photoshop. Using a tripod is generally recommended for landscape photography and is particularly important when shooting for stacking. The technique is really simple and just needs some forward thinking plus a tripod. On the whole I’ve found between three and six photos works best, depending how close the foreground is in relation to the distant background. The scene in front of you will typically dictate how many images will be needed to get front to back sharpness. In these two examples you can see the difference in focus at 100% magnification for the areas in the front and back of the beach shot, using a sequence of four images. Focus stacking provides a really simple technique to overcome this limitation in depth of field. This can make an image look less sharp, and if we’re focusing really close even f/30 can be too shallow. We do get a greater depth of field with a narrower aperture, however anywhere over f/11 can cause diffraction, depending on the lens being used. ![]() That’s the case with the finished example above, where the patterns in the sand is sharp, right though to the cliffs in the background. For landscape photography we would generally use focus stacking when we’re shooting with a wide angle lens and need to get something close in the foreground sharp, all the way to a distant background. The main reason to stack images is to get a deeper focal depth, with front to back sharpness, or somewhere desirable in between. Lucky and persistent as I went to this location around 10 times before getting these conditions. I was lucky that the conditions all came together for this shot with light, colour, tonal balance and the tide all perfectly aligned. This is a beach scene during sunset, which was made with four RAW photos in the sequence. Let’s start off with the finished result of a focus-stacked image.
