How to Shoot Super Macro Photos

In this post, professional photographer Yanik Chauvin from Yanik’s Photo School shows us how to take stunning super macro photos.

I’m a big fan of macro photography. So much so that when I chose my first ever digital camera, the Nikon Coolpix 4500, it was mostly base on its macro capabilities. And when I purchased my Nikon D70 with kit lens, the next lens in my bag was the Sigma 105mm macro.

After shooting lots of macros, I wanted to push the envelope and see if there was a way to get even closer to my subject (without the need for a microscope). Looking on the net, I found a photographer who did just that! Boy was I a happy camper. I have since been using this technique called “Super Macro” to take some pretty amazing photography.

Ok, before I get into the “how to”, let me first give you a brief explanation of what macro is. It’s basically close-up photography where the image projected on the camera sensor is relatively the same size as your subject. We give this term a ratio of 1:1. Most standard macro lenses give you up to 1:1 ratio. As for super macro, depending on your lens combination, you can usually get a ratio of 2:1 or greater. What this means is that your sensor sees closer than the human eye which leads to some unusual photography.

Equipment

Alright! Let’s look at what we need to achieve super macro photos.

  • A macro lens (ideally a prime lens)
  • A fast lens (ideally a prime lens with f1.8 or f1.4)
  • A step-down ring
  • A portable flash
  • A tripod

The reasons why I suggest prime lenses is that they’re the sharpest lenses and when you’re staking that much glass in front of your sensor, things then to go soft very fast. The step-down ring should match your lenses’ respective diameters.

There are other ways to setup for super macros, some using extension tubes or teleconverters, but I wanted to keep it simple.

Setup

Now, let’s make it work.

Step 1: Put the macro lens on the camera (in my case it’s the Sigma 105mm)

Step2 : Make sure your lens is on manual focus

Step 3 : Screw the step-down ring onto the macro lens

Step 4 : Turn the aperture dial on your fast lens (in my case it’s the Nikkor 50mm) to it’s widest setting (smallest f-stop #). We need as much light as possible getting in.

Step 5 : Screw the front of the fast lens onto the front of the macro lens.

Step 6 : Put your camera on manual focus

This is what the setup should look like.

The reason I added the tripod and the flash in the equipment list is that, since there isn’t a lot of light making it to the sensor, you’ll either need a long shutter speed or more light.

You’ll notice that your depth of field (DOF) is extremely small (roughly 1 or 2mm) so things get blurry very fast. Make sure your subject isn’t moving or else you’ll be out of focus. If you insist on doing this hand held, exhale before you press the trigger… you might get lucky. ;-)

Being so close and having such a small DOF is a great combination for fun abstract photography. Use you imagination and have fun!

As for the flash, you’ll have to trigger it off camera because of the length of the combined lenses and the proximity of the subject to the lenses.

Here are some samples images as examples.

Key Ingredients for Black and White Images

Digital Camera Magazine (UK) has a useful feature in their October issue on Black and White photography. It contains a lot of good information - but one of the topics that they cover was on how to ’see in black and white’.

In it the author shares 4 ‘key ingredients’ of that will help you to visualize whether a scene will work as a black and white image or not. The titles below are from the article - the thoughts are mine (and I’ve added one of my own tips too).

1. Look for Contrast

One of the elements that can give interest to a black and white shot is contrast. Because you can’t use color to distinguish one element of your image from another the tonal variances become all the more important. This doesn’t mean you need to look for stark contrasts in every shot you want to convert to black and white - the subject matter will come into play here - but you should ponder how the contrast will come into play when composing your shot.


2. Wait for the Right Light

Linked to contrast, the lighting in a black and white shot can be very important. For example - h3 or direct lighting will often add to contrast. Side lighting will reveal any texture that a subject might have (and in portraits will accentuate features) and light from any one direction will create shadows. All of these techniques can add interest to a black and white image - however they can also be distracting - so play with light with care.

3. Shapes and Patterns

Patterns or shapes that can sometimes almost go unseen in color (due to the color itself drawing attention) can come alive in a black and white shot. Black and White shots that rely upon pattern can often take on an abstract quality.

4. Capture Texture

I’ve already mentioned this above when talking about side lighting - but revealing the texture of a subject can add a new dimension to an image. The sidelight does this by creating shadows.

A Tip for Black and White Landscapes

One more quick tip of my own for those wanting to try black and white landscape photography:

When shooting black and white landscapes look for ‘active skies’. I was given this advice by a photographer a few months ago who showed me some examples of his own black and white landscape work. The skies in his images were breathtaking with wonderful cloud formations and what often looked like storms about to break. Having skies with so much ‘action’ in them added mood and a really dynamic look and feel to his images. Without this active element the images looked rather empty and dull. I think the same principle could be applied to most types of black and white images that have large parts of them dominated by any one thing. If a large part of your image is all the same tone the image can look quite lifeless (unless of course you’re going for a more minimalist look.

Shooting Landscapes with Longer Focal Lengths

One of the simpler tips that I would suggest for those wanting to add a little variety to their landscape photography is to shoot with longer focal lengths.

While the majority of landscape photography is done with wide angle lenses (and rightly so - it’s a great way to capture to dramatic wide vistas) it can be very effective to take a lens with a longer focal length with you next time you set out to capture a scene.

Longer focal lengths can be particularly effective in those over-photographed locations where images can end up looking a little cliched. They’re also great for capturing patterns and layers on the horizon that often go unnoticed in landscapes shot with a wide lens.

A quick tip for those shooting landscapes with longer focal lengths - make sure you use a tripod. With longer focal lengths, any camera shake or movement will be amplified. The longer the lens the more noticeable it will become. So secure your camera and consider using a remote shutter release of some kind.
