Focus stack of four shots manually blended in Photoshop. The longer the focal length, the more likely you’ll need to use focus stacking when you have close foreground objects, but even with a 14mm lens you may need to use focus stacking when you’re very close to the ground, making it nearly impossible to get the very close foreground and distant background in sharp focus in the same shot. It’s fairly often that I have to spend an hour or even multiple hours blending all the exposures, particularly when it comes to landscape astrophotography images that require a difficult blend of a brightly exposed foreground with a dark sky.įocus stacking is needed in situations where it’s either impossible to get everything in focus in one image or you want to avoid the softness that high ƒ-stops produce due to diffraction. The process varies from easy to incredibly time consuming and complicated, depending on your level of OCD.

So, what exactly is focus stacking? It’s the process of taking multiple exposures at different focus distances and blending them in software to create an image that’s sharp from the closest foreground object to the furthest background object.
It definitely takes patience, yet the process is well worth it if you’re looking for the best-quality images, particularly if you like making large prints and want to retain the sharpest details possible. But with some tips and a bit of practice, you can be on your way to making sharp images at any focal length and angle of composition. Nikon D810, NIKKOR 24-70mm ƒ/2.8, all shots at 36mm and ISO 80Īre you a landscape photographer suffering from out-of-focus foregrounds or backgrounds even when you shoot at ƒ/11? Or are you tired of using ƒ/16 or ƒ/22 to get everything in focus, yet suffering with image softness because of diffraction? Then focus stacking may be for you.Ĭhances are, you’ve heard of this technique by now-maybe you haven’t tried it or had trouble with it because of the complexity.
