My test of the Canon R5’s Focus Bracketing — or focus stacking — continues.
I’ve been working with the Canon R5’s focus bracketing (or focus stacking) since I bought the camera. Overall, I’ve been impressed. Here are my previous blog postings on this topic.
Questions have come up during my tests and in talks with other photographers.
What increment should be used? The Canon R5 comes set at increment 3. That’s a good starting point and what I used on my first tests.
I changed to increment 7 for the purple passionflower blooms. I like 7 now.
How many photos are needed for a good photo stack? Obviously, that depends on how deep the subject is. I used 10 on the long-tailed skipper and 10 on the red passionflower bloom. The skipper is much smaller than the flower.
In my tests, 10 photos seems to be a sweet spot. The Canon R5 takes less than a second to fire off the series of images. Push the shutter button one time and the camera does the rest.
I used Photoshop’s focus stacking and tried 3, 5, or 1o images. The stacks with 10 images were smoother and better aligned.
Where should the focus point be at the start of the stack? Focus should be on the closest point to the camera. That’s a lesson learned.
On the long-tailed skipper, I focused on the wing closest to the camera. In earlier tests, I focused on the head and the wing closest to the camera wasn’t sharp.
On the red passionflower, I focused on the flower in one photo. In the second photo, I focused on the buds in front of the bloom. Notice the difference?
All photos were taken with the Canon R5, 100-500mm lens, 1.4x extender, f/11, ISO 400.
Questions? What’s been your experience with the R5’s focus bracketing? Does your mirrorless camera have focus bracketing or stacking? Experience?
