I could have done that,īut I knew I was going to be waiting a while either way since it was dark out, although Have taken at least one more shot for the foreground at a closer focus point the veryĬlose foreground rocks are actually out of focus. The sky was shot at ISOĢ000 for 30 seconds and the foreground consists of three shots, all at ISO 800, one forģ0 seconds and the other two for 60 seconds each. 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.
