    This must have taken some serious processing time to put all the images together but great result!

      About an hour typically, not sure if that's a long time or not haha

    Very clever. How do you move the camera only 0.25mm at a time? I recently bought myself a Macro lens to play with and I'm amazed how shallow a DOF it has. Today I photographed this https://www.clickasnap.com/i/63g5oqwluwdl2v2p">Snowdrop but had to resort to a more soft focus effect than I wanted.

      I'm releasing a blog article later this week showing all the kit. In short it's quite tricky to do by hand and can result in missed focus points

        A friend of mine photographs insects & flowers using focus stacking in Photoshop. But he hand holds his camera & just rocks forward while firing his shutter on burst. Maybe 7-10 images. He achieves pretty stunning results like that. I'm surprised you need so many images?

          The lens i use is not a normal macro lens, it actually has a 1:5 ratio rather than a 1:1 it means even full stopped out it's depth of field is in the order of fractions of a millimetre hence the huge amount of images required :)

            That's not a cropped or post edit zoomed in picture you see there. That's full size on a full frame camera ;)

    I take it each image has a different point of critical focus to achieve a deeper dof ? I have never gotten into stacking therefore not sure I understand it.

      I'm releasing a blog post on it this week. But yes basically you take a picture then move the whole camera and lens assembly about 0.25mm take another picture and carry on until the picture is complete you then use something like helicon focus to stack them. Its really cool

        Thanks Tom. I admit it is fun to experiment.
