Extreme Macro Photography. Focus-Stack using Photoshop. A Post By: Don Komarechka One of the biggest challenges facing macro photographers is getting your subject in focus.
Not only is hitting the perfect focus point an exercise in frustration, but often you don’t have enough in focus. Unlike a landscape photographer who can set their aperture to F/22 and be happy, a macro shooter will likely be rewarded by blurry images – and even if they are sharp, the focus still won’t magically spread from edge-to-edge. The best solution is to use a technique called “focus stacking”, which combines multiple frames together to increase the area of the image that is in focus. Focus stacking requires you to photograph your subject at every single possible focus point you’d like to have sharp, and then combining those images together to get one image where everything has detail.
Pollen inside a flower. Shooting: There are a few tips to get started with hand-held shots intended to be focus-stacked. You’ll also want the camera on continuous shooting. Remote Focus stacking. Focus stacking is a technique for increasing the depth of field by taking a series of photographs with different focus settings and then combining them together using the areas in focus from each image.
This technique is useful for macro and close-up photography, landscapes, product photography and any other image where the depth of field is critical and the subject isn't moving. The live view display in DSLR Remote Pro makes it very simple to automate the process of taking a sequence of images with different focus settings by running a script. There is no need to touch the camera and the mirror stays locked up during the sequence which minimizes the chances of camera shake or movement. Once the pictures have been taken they can be combined using free software such as CombineZM or commercial software like Helicon Focus (the example images on this page were combined using CombineZM). Example 1 Model car Combined image from 38 shots taken with Canon EOS 40D, 50mm f/1.8 lens @ f/5.6. Focus Stacking. Editor’s note: This excerpt first appeared in photographer and author Harold Davis’ recent Focal Press book, Photographing Flowers: Exploring Macro Photography with Harold Davis.
The closer you get in macro flower photography, the fussier focus gets. Since “fussy” is not a technical term, let me explain. Because focus is inherently shallower as you get closer to your subject, slight variations of distance between camera and subject throw you out of focus very quickly, and even fully-stopped down you may not have enough depth-of-field for your entire photo to be in focus. Certainly, stopping your lens down to its smallest aperture, observing whether you have the in-focus areas you want, and seeing if there is any way to position the camera to improve the amount that is in-focus is a good way to start. The combination of images can be accomplished by hand-painting to select the areas you want or using automated layer alignment and stacking software (see text box below). Layers Palette. How-to from Photo.net. How to take close-up pictures of small things by Philip Greenspun, June 1997 (updated January 2007) macro \'mak-(.)ro-\ aj [macr-] 1: excessively developed : LARGE, THICK 2: of or involving large quantities 3: GROSS Taking close-up pictures of small things is called "macro photography.
" I have no idea why. Perhaps because the small things in macro photography are generally larger than the things you are taking pictures of when doing "micro photography". If you really want to be pedantic then you should say you are doing "photomacrography". What Kind of Camera Point and shoot digital cameras can have remarkable macro capabilities, but for best results you want a single-lens reflex camera. A typical setup might be a Canon Digital Rebel XTi (Black) (review) with a Canon EF-S 60mm f/2.8 Macro USM (review). Comprehensive Guide. When we photograph something very small we call it a macro photography.
I would imagine we should call it Micro photography, but I don’t have control over the jargon. Shooting small things poses great challenges and comes with high rewards. In this tutorial I to get all the info that you’d need to take macro shots. starting from equipment through subjects and tip and wrap up of some of my favorite macro photographers on Flickr if you need some extra inspiration.
When we talk about macro photography we tend to think about small things that we shoot from a close distance. This definition works for me as an on-the-nose definition and is probably right for just about 95% of all macro images. Ratios Way back in film days macros used to have ratios. The Ration (or Macro Ratio) is the difference in size between the “real” size of the subject and the size that subject was caught on film.
To make things non technical, let’s just say that the ratio is, the larger magnification it means. Equipment. Depth of Field in Macro Photography. The defining characteristic of macro photography is of course that subjects are shot at close distances.
While this close camera-to-subject proximity can lead to visually arresting images captured from an intimate perspective, this sort of photography presents unique technical challenges as well. In this article I'll address one of the most significant of these challenges - controlling depth of field (DOF).
