Focus Stacking

B_PB1903

Yesterday afternoon I decided that I would have a little experiment with Focus Stacking, to be honest, it wasn’t really something that was on my radar until recently, I it seemed like it was something rather complex & requiring of special software, but a bit of research & some experimentation and some trials (none too scientifically done, largely kind of finger in the air, seat of the pants stuff) but with a little practice I think that I can nail it. I have a project that I am thinking of using it on  in the not too distant future.

It’s not perfect but this was my first attempt, gladly receive any pointers from anyone with some experience.

Finished Focus Stack

The final image is a composite of 22 images, whilst not perfect it is, I think close, I shall have another go later in the week. The images were shot on a Canon 100mm Macro lens at 39cm at F6.3, the amount of DoF at that distance at that aperture is very little. The image below is the first in the sequence.

SO 21 images later I have gradually moved the point of focus to the back of cable. And have a selection of images that I can focus stack. I used PhotoShop 2018 on a Mac, if you are on a PC the functions maybe in a slightly different place, but this was my process.

Having copied the files to the hard disk, I then loaded them into a Stack.

Then chose the files that I wanted to work with.

If you click the Auto Align option at this stage it saves you having to do it later, manually. This process can take a little while depending on the size of the files & the power of your machine.

Once loaded select all of the files in your stack, as show below

Then Auto Blend

And that is it, job done, now it’s time for a beer.
