Having elements only inches from your camera or shooting with a longer lens will increase the number of images. Since the R5 considers the current aperture when adjusting focus, the number of images will usually range between three and six with the most narrow setting when shooting at f/9.5 with a wide lens. Setting a wider increment might result in fewer photos and a quicker bracketing sequence, but blending the image will become more challenging. I have set up the R5 to use the most narrow focus increment during bracketing. But tests and extensive pixel peeping showed that in the majority of cases, the difference in quality between 12- and 14-bit is negligible. At first, I was hesitant to use it, because it uses an electronic shutter resulting in 12-bit raw files versus the 14-bit raw files you get in the other shutter release modes. It has quickly become one of my favorite features of the Canon EOS R5. The in-the-field process got much simpler as camera manufacturers began introducing automatic focus bracketing. Placing the focus points too far apart could also still happen. This approach is good enough for the web, but the results often lack detail in large-format prints.Įven when touch screens later allowed for faster focusing and hence faster capturing of a stacking sequence, it often still took too long to capture all the photos.
So often, the only way to get a photo after all was to stop down the lens and increase the ISO. Stacking them involved a lot of retouching. Moving elements were a big problem because of the time required to manually shift the focus between individual exposures. In the beginning, though, it was difficult for some scenes. Usually, I try to shoot at f/9.5 for the best compromise between overall sharpness and depth of field.īecause fiddling around with the hyperfocal distance was slowing me down too much while still just giving me "acceptable" sharpness, I already made focus stacking a routine more than 10 years ago when I got my first full-frame camera, the Canon 5D Mark II. I was never satisfied with the results obtained by stopping down the lens. Focus stacking has always been my choice for landscape and architecture photos requiring a large depth of field.
