It is cold and snowy in beautiful Colorado today so the activity was indoor photo experiment with focus bracketing. I thought I would give it a shot (pun intended) with Fuji XT3 and see how it works. It is a little tricky to set it up, but once you get the hang of what is happening it is not so bad. Tripod is required! Be sure to use the electronic shutter to reduce camera shake.
Steps:
- Set the drive to BKT
- In the Shooting Settings Menu select Drive Setting > BKT Setting > Focus BKT
- Set Frames - this is how many photos you want to take.
- Set Step - this is the focusing steps. Think of the steps as 'slices'. The camera shoots from bottom to top so set your focus for the first frame to the lowest part of the subject you want to capture. The XT3 will shoot continuously for the number of frames and focus the number of slices.
- Interval...I didn't use this. My guess it is for a moving subject?
What I discovered is that the Steps set at 10 works well if you are wanting the background in focus, but if you set the Frames too high you will get a bunch of out of focus images of the background. I was shooting some close ups with a 55-200 MM lens on a tripod with some lighting Depending on my focal length I would increase/decrease the frames. It was all trial and error. For the shots below I took 20 frames with 10 steps.
What is really cool is that you can see the focus steps in the live preview while they are being captured! I was able see when I didn't have enough frames set up.
