Capturing Sun-rays

Sunlight that appears to look like rays in a landscape, is very attractive to look at. These rays can add the magic to even the simplest of landscapes, transforming them into works of fine art.

For effective landscapes with this effect, there are four simple steps. The creation of any photograph starts with visualization and goes through darkroom work and finally culminates as a print. In landscapes showing these ‘sun’s rays’, all these steps play important roles.

 

The Haze

Atmospheric haze is the first prerequisite for such photographs. Haze can be due to fog, mist, smoke or even fine dust. A simple scientific principle comes into play here. The suspended particles in the air, scatter the light and this scattered light is what we have to highlight. The effect is called Tyndall Effect.

The creation of the effect ( sun’s rays )

To sunlight passing through the hazy air gets scattered and becomes visible. However to actually show it as directional rays of sunlight, there have to be areas where this effect is not visible. The simplest solution to this in landscapes is to have objects that prevent the light from going to the hazy air.  These can be tall bushes, trees, mountains and even clouds. To further pronounce the effect, light falling from an angle looks even better.

Think of early morning walk in the woods on a cold foggy winter morning. The light-rays from rising sun will show itself in the foggy atmosphere as bright bands, separated by areas where the trees prevent the light from passing through the fog (effectively their shadow region).

 

Camera settings

Keeping in mind the post-processing that will be required to enhance the effect, here are some more things to keep in mind –

  • Click ‘raw’ and then post-process.
  • Use the lowest possible of the native ISO setting.
  • Preview the histogram after capturing the photograph. There should not be any clipping. (Understanding Histograms)
  • Usually such images have histograms which are limited to a small part of the available range. This is perfectly fine. Just ensure that the exposure is such that the maximum area is in the central part of the histogram.

(The histogram as seen in the curves tool, of a usual foggy landscape, predominantly limited to the central part of the available dynamic range. A similar histogram will be seen on the preview screen of the camera too. This is from Affinity Photo since I wrote this article after transferring the photographs to my computer.)

  • Do a sensor cleaning before capturing such photographs.
  • Use a tripod even if you feel that the light is enough to enable hand holding the camera at 100 ISO and with the required aperture setting.

 

Post-Processing

This is an important step in such photographs. There are two major things to do for making the effect more visible. The tool to be used for this purpose is the super-powerful Curves Tool (Curves Tool at your service). Here are the steps to get the required effect –

  • Shift the white and black points to the ends of the histogram. This is to make use of the whole available dynamic range. See the image below. The red line is the default and the white ‘curves’ line is the new setting. The black point at the bottom left has been shifted towards the histogram to a large extend and the white point on top has also been shifted slightly towards the histogram. The first effect of this is the overall increase of contrast and also a resulting increase in the sun-rays effect.
  • Look out for two major problems with this change.
    • First, the fine gradations of color may break up, leading to sudden change in shades. This is called banding. Be on the lookout in the regions with fine gradations like skies. If you carefully observe the shift in black point in the Curves Tool below, you’ll notice that I have stopped well before the place where histogram starts. This was done to prevent banding.
    • Second problem with this is with the dust particles. By doing as described above, sometimes hidden dust-bunnies of the sensor may become obvious in plain areas like skies. This is why is stressed upon the need for a clean sensor initially. If they do come up in the photograph, use a ‘Healing Tool’ to get rid of them. (Clone Stamp vs Healing)

 

  • Use a curves setting similar to ones shown below to further enhance the effect. This will affect only the mid-tones and improve their contrast. ‘S-Shape’ curve adds contrast. This may or may not be required, depending on the level of contrast already there in the mid-tones.

I recommend using the curves tool twice for the above settings rather than trying to perform both the adjustments in one go. I find doing specific things easier with the tool, rather then trying to do a lot of enhancements at the same time. A word of precaution – Curves tool is a very powerful tool. So, be careful. Keep the changes to a little less than what you feel is fine.

 

Another easier option is to enhance the ‘dynamic contrast’ if such a tool is available in your favorite image editing program.

A little amount of old school burning and dodging can also help in enhancing the effect.

 

The Print

Such fine shifts in tints and shades, that show the beauty in these sun-rays can get lost to poor printing jobs. My recommendation is to make use of a professional photo printing service which uses calibrated machines and a high grade paper. If you are planning to print at home, calibrate your printer first.

I had to face a similar situation some time back, when one of my photographs which was printed locally was made overly bright and it ended up loosing the sun-ray effect which had lighted up the main compositional element. Though the effect is not visible on display screens, you can still read about the mishap here – Annoying Little things
