    Hi there. I take the photos for our local scale model club for the club web site (http://www.ipms-clacton.org.uk). Up until now I have had a Canon 80D and then a Samsung phone (with 48mp resolution). I have been using focus stacking by selecting each focus point manually and taking around 8 - 10 images. I then use Helicon Focus to stack them into one image.

    I now have a Canon 90D and have been reading about Focus Bracketing in 90D for Dummies.

    I find that the camera is not taking the full number of images requested. For instance, if I ask it to take 20 images, it takes 13. I have now set it to take 100 but it only took 19. Is there some reason that I don't grasp?

    i briefly took a look at this a day or so ago as i saw on one of my feeds someone took a focus bracketed image with a model plane large scale.
    i was more interested in the fact it could be done in the 90d but from the quick vid i saw the lenses make a difference and also weither you set it to wide or narrow.

    apart from that i havent really got much else but i had been looking at the 90d and the M6mkII as an additional camera body,
    if i'm right the 90D does the bracket stacking in camera and can produce a single image straight from camera?
    the M6mkII needs to have it done in post?

    (edit) lol it was one of your posts i saw here!!

    I think I understand what is going on here. I can set up focus bracketing (not stacking) with "upto" 100 images. It seems that the number of images that I get depends on how many focus points the camera finds so sometimes I get 18 images and other I get 50!

    I am careful to say "focus bracketing" because I still have to use a 3rd party program to "stack" them into a single image. I currently use Helicon Focus. I was using a program called Focus Stacker on my M1 Mac but, even being free, it is much slower than Helicon Focus and, when I use this, I often have up to 30 images to stack so a bit of speed is useful.
