Focus Stacking with Fujifilm: trying it out and documenting the process.

No matter whether you are a hobbyist or a professional photographer, it is without a doubt that we all want to maximise the functionality of our cameras and of course, test out newly released functions to see what they can do for us whether it is in our work or passions.

And it seems that among all the interest and hype generated with Fujifilm updating the GFX50S, X-H1 and X-T2 with thefocus stacking function, there have been few places online detailing a process coming to the steps to do so and this is what I hope to do so today. 

So let us start on: Focus Stacking in Fujifilm.

To start off, the equipment of my choice was the X-H1 and the XF90mm F2.
(If you are curious why not the GFX50S and the GF110mm, the frank reason is I do not have confidence my entry level iMac would be able to handle the processing of stacking GFX50S files and so yeap 😑


This wasn’t a shoot for a client and more of me trying to document a visual process for everyone on the focus stacking process hence I agree there are many ways where the process can be improved: from using a stronger tripod, better backgrounds, better post processing, a more expensive watch, remembering to wipe off my fingerprint, shooting at ISO 200 etc but again, my concern here is to share the process so more of us will be acquainted and not find the focus stacking process daunting.


Setup was simple with a Foldio 3 studio, a Manfrotto Pixi (I 100% suggest as strong a tripod you have and I was literally being lazy here)

In camera, it was a quick jiffy accessing the Focus stacking options at:

Menu → Shooting Settings → Drive Settings → BKT Setting → Focus BKT. 

The most often asked questions come next, which is what values does one set for Frames/Step/Interval.

My best answers are:

Frames: The number of frames you wish to take, note you can do up to maximum of 999 frames but the higher the number of frames will also mean more work later stacking the images in post processing.

Step: My understanding of this is it affects how much the sensor moves between shots. Min value is 1 to a Max of 10. Lower the number, the less the focus change will be. 

Interval: The timing between shots in seconds, min value is 1 to a Max of 10. My gut feels are go for a 2~4 seconds so that the camera doesn’t have to rush through and you don’t feel yourself aging waiting.

For this round, my settings were: 40 frames, 3 steps and 2 seconds. My gut feeling was of if its a small item like a 40mm watch, its likely 40 frames will be sufficient for good depth of field across, 3 steps from gut feeling again and 2 seconds just so that the camera won’t take too long between shots. There maybe someone with a magical formula out there but for now, I haven’t seen any and I guess there’s a bit of experimentation involved as we prod along. 

I also shot in Electronic Shutter mode to minimise vibrations and like all good photographers, I used manual focus here to ensure I don’t miss the (ahem) focus. 

and so, once ready, depress the shutter and one is set to go.

Shot 11 of 40, the camera will do its fair share of work now.

Once done, I downloaded the files and uploaded them into Adobe LR.

Yeap, 40 of them.

And to give a quick explanation why we need to do focus stacking is that when doing close up shots (of products especially) the depth of field is generally insufficient across the image and focus stacking allows a solution where we simply layer and stack images shot across different points of focus in the same image to form a single final image where it is focused all across.

The following images below show some of the 40 shots done, and why depth of field was lacking across (aperture used was F5.6)

DSCF1857 (note straps, and the 15 min markings) DSCF1863
(note bottom , especially the 30min markings)

(note name of brand)

Within Lightroom, I adjusted the white balance and exposure and used the Sync function to ensure uniformity across the 40 images.

Once done, the next step is to export to Photoshop CC by going to the ‘Library’ module, selecting all the images and right-clicking to select the ‘Edit In’ and then ‘Open as Layers in Photoshop’ option.

Once this is done, we have to wait a while for Photoshop to load the layers. Waiting time is dependent on how fast the system can process the workload.

Under Layers, one can see all the images we are now going to use.

Once all the images have loaded in Photoshop, select all the layers (images) – go to Edit Menu and select ‘Auto-align Layers’. It is good to use the default settings and this can be quite a slow process. 


Once this is done, we will go back to Edit Menu and now select ‘Auto-Blend Layers’ allow Photoshop to do a final round of clean-ups to the image.  

As a comparison, it took around 20 mins for my system to get all this done. (iMac 2017 21 inch base model) 

Once the whole process is done, we are almost there. Make any further adjustments one will need and once done, simply ‘close’ the project and choose to save the project and yeap, we are back to Lightroom with a merged file in ‘tif’ format for your final touches. 

and finally, with all your needed adjustments done in Lightroom, export the image and you are done ! 

My final ‘tif’ file weighed in at close to 200 megabytes, and this was from processing 40 JPEG images. (yes, using RAW is better and allows you way more latitude) but if space is an issue, do take note that final files can be huge. 


The final stacked shot. 😄 

And at the end a few things I really have to confess while trying out this feature are:

  1. A macro lens would have been much more appropriate, but I didn’t have access to either an XF80 or XF60 so this was with what I had available.
  2. Settings. The lower the ISO the better, I should have set ISO200, but in a rush to get things done I used ISO640. Aperture size wise, as a friend reminded, F5.6 was ‘not here nor there’ and I gotta learn more.
  3. Post processing. I am sure there’s more methods out there than the one I shared, pls do share with me if there’s better methods as I am still trying my best to figure out focus stacking rightly.

  1. Hi nice article. If you are seriously into stacking, consider the application Helicon Focus. It will speed up the operation tremendously, as well as the quality. There is a free trial.
