Macro Lens ConversionĮxtension tubes and macro converters are the most popular ways of making your lens macro-capable.

But we will not be using dedicated macro lenses capable of close focusing but rather enhancing existing standard lenses we had with macro accessories. The focusing method using the autofocus motor inside the lens is the most favorable choice in many situations.įor examples made in this article, we will use mirrorless cameras (Sony A7IV and Fuji XT5) with lenses capable of autofocus. Additionally, there are advanced workflows involving macro bellows. These can be done with electronic control and motors or by hand. Standard techniques are changing the focus for each photo or adjusting the distance between the lens and the subject. We can do focus stacking in a few different ways. Lastly, with the help of automated processing, we make only the focused part of each image visible, thus getting a shot where the entire subject appears to be in focus. Then we take those photos and stack them on top of each other. The principle is straightforward - we take many photos at different focus values or distances and cover our entire subject with the focus zone but in separate images. To combat thin DOF, we use focus stacking or bracketing. Focus is the number one tool in creating technically sound and aesthetically pleasing images. A misfocused or entirely out-of-focus photo is a failed image in all photography fields. Our eyes automatically seek out the focused parts of the photo while ignoring the blurry background or foreground. The depth of field is the plane where things are in focus, and all the details are visible. In this article, we will discuss focus stacking techniques and connect the dots on why focus stacking is necessary for small-scale photogrammetry. In practice, this means when the subject is very close to the lens and appears large in the frame. The thin depth of field results from large subject magnification and open aperture. It is bread and butter for macro photographers because close-up photography deals with the razor-thin depth of fields.

Focus stacking is a technique that involves taking a lot of photos and combining them to create an image that does not contain a narrow focus zone.
